Overview ¶

Package op defines functions for adding TensorFlow operations to a Graph.

Functions for adding an operation to a graph take a Scope object as the first argument. The Scope object encapsulates a graph and a set of properties (such as a name prefix) for all operations being added to the graph.

WARNING: The API in this package has not been finalized and can change without notice.

Example ¶

// This example creates a Graph that multiplies a constant matrix with
// a matrix to be provided during graph execution (via
// tensorflow.Session).
s := NewScope()
input := Placeholder(s, tf.Float) // Matrix to be provided to Session.Run
output := MatMul(s,
	Const(s, [][]float32{{10}, {20}}), // Constant 2x1 matrix
	input,
	MatMulTransposeB(true))
if s.Err() != nil {
	panic(s.Err())
}
// Shape of the product: The number of rows is fixed by m1, but the
// number of columns will depend on m2, which is unknown.
fmt.Println(output.Shape())

Output:

[2, ?]

Functions ¶

func Abort ¶ added in v1.1.0

func Abort(scope *Scope, optional ...AbortAttr) (o *tf.Operation)

Raise a exception to abort the process when called.

If exit_without_error is true, the process will exit normally, otherwise it will exit with a SIGABORT signal.

Returns nothing but an exception.

Returns the created operation.

func Abs ¶ added in v1.1.0

func Abs(scope *Scope, x tf.Output) (y tf.Output)

Computes the absolute value of a tensor.

Given a tensor `x`, this operation returns a tensor containing the absolute value of each element in `x`. For example, if x is an input element and y is an output element, this operation computes \$y = |x|\$.

func AccumulateNV2 ¶ added in v1.5.0

func AccumulateNV2(scope *Scope, inputs []tf.Output, shape tf.Shape) (sum tf.Output)

Returns the element-wise sum of a list of tensors.

`tf.accumulate_n_v2` performs the same operation as `tf.add_n`, but does not wait for all of its inputs to be ready before beginning to sum. This can save memory if inputs are ready at different times, since minimum temporary storage is proportional to the output size rather than the inputs size.

Unlike the original `accumulate_n`, `accumulate_n_v2` is differentiable.

Returns a `Tensor` of same shape and type as the elements of `inputs`.

Arguments:

inputs: A list of `Tensor` objects, each with same shape and type.
shape: Shape of elements of `inputs`.

func Acos ¶ added in v1.1.0

func Acos(scope *Scope, x tf.Output) (y tf.Output)

Computes acos of x element-wise.

func Acosh ¶ added in v1.3.0

func Acosh(scope *Scope, x tf.Output) (y tf.Output)

Computes inverse hyperbolic cosine of x element-wise.

func Add ¶ added in v1.1.0

func Add(scope *Scope, x tf.Output, y tf.Output) (z tf.Output)

Returns x + y element-wise.

*NOTE*: `Add` supports broadcasting. `AddN` does not. More about broadcasting [here](http://docs.scipy.org/doc/numpy/user/basics.broadcasting.html)

func AddManySparseToTensorsMap ¶ added in v1.1.0

func AddManySparseToTensorsMap(scope *Scope, sparse_indices tf.Output, sparse_values tf.Output, sparse_shape tf.Output, optional ...AddManySparseToTensorsMapAttr) (sparse_handles tf.Output)

Add an `N`-minibatch `SparseTensor` to a `SparseTensorsMap`, return `N` handles.

A `SparseTensor` of rank `R` is represented by three tensors: `sparse_indices`, `sparse_values`, and `sparse_shape`, where

```sparse_indices.shape[1] == sparse_shape.shape[0] == R```

An `N`-minibatch of `SparseTensor` objects is represented as a `SparseTensor` having a first `sparse_indices` column taking values between `[0, N)`, where the minibatch size `N == sparse_shape[0]`.

The input `SparseTensor` must have rank `R` greater than 1, and the first dimension is treated as the minibatch dimension. Elements of the `SparseTensor` must be sorted in increasing order of this first dimension. The stored `SparseTensor` objects pointed to by each row of the output `sparse_handles` will have rank `R-1`.

The `SparseTensor` values can then be read out as part of a minibatch by passing the given keys as vector elements to `TakeManySparseFromTensorsMap`. To ensure the correct `SparseTensorsMap` is accessed, ensure that the same `container` and `shared_name` are passed to that Op. If no `shared_name` is provided here, instead use the *name* of the Operation created by calling `AddManySparseToTensorsMap` as the `shared_name` passed to `TakeManySparseFromTensorsMap`. Ensure the Operations are colocated.

Arguments:

sparse_indices: 2-D.  The `indices` of the minibatch `SparseTensor`.

`sparse_indices[:, 0]` must be ordered values in `[0, N)`.

sparse_values: 1-D.  The `values` of the minibatch `SparseTensor`.
sparse_shape: 1-D.  The `shape` of the minibatch `SparseTensor`.

The minibatch size `N == sparse_shape[0]`.

Returns 1-D. The handles of the `SparseTensor` now stored in the `SparseTensorsMap`. Shape: `[N]`.

func AddN ¶ added in v1.1.0

func AddN(scope *Scope, inputs []tf.Output) (sum tf.Output)

Add all input tensors element wise.

Arguments:

inputs: Must all be the same size and shape.

func AddSparseToTensorsMap ¶ added in v1.1.0

func AddSparseToTensorsMap(scope *Scope, sparse_indices tf.Output, sparse_values tf.Output, sparse_shape tf.Output, optional ...AddSparseToTensorsMapAttr) (sparse_handle tf.Output)

Add a `SparseTensor` to a `SparseTensorsMap` return its handle.

A `SparseTensor` is represented by three tensors: `sparse_indices`, `sparse_values`, and `sparse_shape`.

This operator takes the given `SparseTensor` and adds it to a container object (a `SparseTensorsMap`). A unique key within this container is generated in the form of an `int64`, and this is the value that is returned.

The `SparseTensor` can then be read out as part of a minibatch by passing the key as a vector element to `TakeManySparseFromTensorsMap`. To ensure the correct `SparseTensorsMap` is accessed, ensure that the same `container` and `shared_name` are passed to that Op. If no `shared_name` is provided here, instead use the *name* of the Operation created by calling `AddSparseToTensorsMap` as the `shared_name` passed to `TakeManySparseFromTensorsMap`. Ensure the Operations are colocated.

Arguments:

sparse_indices: 2-D.  The `indices` of the `SparseTensor`.
sparse_values: 1-D.  The `values` of the `SparseTensor`.
sparse_shape: 1-D.  The `shape` of the `SparseTensor`.

Returns 0-D. The handle of the `SparseTensor` now stored in the `SparseTensorsMap`.

func AddV2 ¶ added in v1.5.0

func AddV2(scope *Scope, x tf.Output, y tf.Output) (z tf.Output)

Returns x + y element-wise.

*NOTE*: `Add` supports broadcasting. `AddN` does not. More about broadcasting [here](http://docs.scipy.org/doc/numpy/user/basics.broadcasting.html)

func AdjustContrast ¶ added in v1.1.0

func AdjustContrast(scope *Scope, images tf.Output, contrast_factor tf.Output, min_value tf.Output, max_value tf.Output) (output tf.Output)

Deprecated. Disallowed in GraphDef version >= 2.

DEPRECATED at GraphDef version 2: Use AdjustContrastv2 instead

func AdjustContrastv2 ¶ added in v1.1.0

func AdjustContrastv2(scope *Scope, images tf.Output, contrast_factor tf.Output) (output tf.Output)

Adjust the contrast of one or more images.

`images` is a tensor of at least 3 dimensions. The last 3 dimensions are interpreted as `[height, width, channels]`. The other dimensions only represent a collection of images, such as `[batch, height, width, channels].`

Contrast is adjusted independently for each channel of each image.

For each channel, the Op first computes the mean of the image pixels in the channel and then adjusts each component of each pixel to `(x - mean) * contrast_factor + mean`.

Arguments:

images: Images to adjust.  At least 3-D.
contrast_factor: A float multiplier for adjusting contrast.

Returns The contrast-adjusted image or images.

func AdjustHue ¶ added in v1.1.0

func AdjustHue(scope *Scope, images tf.Output, delta tf.Output) (output tf.Output)

Adjust the hue of one or more images.

`images` is a tensor of at least 3 dimensions. The last dimension is interpretted as channels, and must be three.

The input image is considered in the RGB colorspace. Conceptually, the RGB colors are first mapped into HSV. A delta is then applied all the hue values, and then remapped back to RGB colorspace.

Arguments:

images: Images to adjust.  At least 3-D.
delta: A float delta to add to the hue.

Returns The hue-adjusted image or images.

func AdjustSaturation ¶ added in v1.1.0

func AdjustSaturation(scope *Scope, images tf.Output, scale tf.Output) (output tf.Output)

Adjust the saturation of one or more images.

`images` is a tensor of at least 3 dimensions. The last dimension is interpretted as channels, and must be three.

The input image is considered in the RGB colorspace. Conceptually, the RGB colors are first mapped into HSV. A scale is then applied all the saturation values, and then remapped back to RGB colorspace.

Arguments:

images: Images to adjust.  At least 3-D.
scale: A float scale to add to the saturation.

Returns The hue-adjusted image or images.

func All ¶ added in v1.1.0

func All(scope *Scope, input tf.Output, axis tf.Output, optional ...AllAttr) (output tf.Output)

Computes the "logical and" of elements across dimensions of a tensor.

Reduces `input` along the dimensions given in `axis`. Unless `keep_dims` is true, the rank of the tensor is reduced by 1 for each entry in `axis`. If `keep_dims` is true, the reduced dimensions are retained with length 1.

Arguments:

input: The tensor to reduce.
axis: The dimensions to reduce. Must be in the range

`[-rank(input), rank(input))`.

Returns The reduced tensor.

func AllCandidateSampler ¶ added in v1.1.0

func AllCandidateSampler(scope *Scope, true_classes tf.Output, num_true int64, num_sampled int64, unique bool, optional ...AllCandidateSamplerAttr) (sampled_candidates tf.Output, true_expected_count tf.Output, sampled_expected_count tf.Output)

Generates labels for candidate sampling with a learned unigram distribution.

See explanations of candidate sampling and the data formats at go/candidate-sampling.

For each batch, this op picks a single set of sampled candidate labels.

The advantages of sampling candidates per-batch are simplicity and the possibility of efficient dense matrix multiplication. The disadvantage is that the sampled candidates must be chosen independently of the context and of the true labels.

Arguments:

true_classes: A batch_size * num_true matrix, in which each row contains the

IDs of the num_true target_classes in the corresponding original label.

num_true: Number of true labels per context.
num_sampled: Number of candidates to produce.
unique: If unique is true, we sample with rejection, so that all sampled

candidates in a batch are unique. This requires some approximation to estimate the post-rejection sampling probabilities.

Returns A vector of length num_sampled, in which each element is the ID of a sampled candidate.A batch_size * num_true matrix, representing the number of times each candidate is expected to occur in a batch of sampled candidates. If unique=true, then this is a probability.A vector of length num_sampled, for each sampled candidate representing the number of times the candidate is expected to occur in a batch of sampled candidates. If unique=true, then this is a probability.

func AllToAll ¶ added in v1.12.1

func AllToAll(scope *Scope, input tf.Output, group_assignment tf.Output, concat_dimension int64, split_dimension int64, split_count int64) (output tf.Output)

An Op to exchange data across TPU replicas.

On each replica, the input is split into `split_count` blocks along `split_dimension` and send to the other replicas given group_assignment. After receiving `split_count` - 1 blocks from other replicas, we concatenate the blocks along `concat_dimension` as the output.

For example, suppose there are 2 TPU replicas: replica 0 receives input: `[[A, B]]` replica 1 receives input: `[[C, D]]`

group_assignment=`[[0, 1]]` concat_dimension=0 split_dimension=1 split_count=2

replica 0's output: `[[A], [C]]` replica 1's output: `[[B], [D]]`

Arguments:

input: The local input to the sum.
group_assignment: An int32 tensor with shape

[num_groups, num_replicas_per_group]. `group_assignment[i]` represents the replica ids in the ith subgroup.

concat_dimension: The dimension number to concatenate.
split_dimension: The dimension number to split.
split_count: The number of splits, this number must equal to the sub-group

size(group_assignment.get_shape()[1])

Returns The exchanged result.

func Angle ¶ added in v1.4.0

func Angle(scope *Scope, input tf.Output, optional ...AngleAttr) (output tf.Output)

Returns the argument of a complex number.

Given a tensor `input` of complex numbers, this operation returns a tensor of type `float` that is the argument of each element in `input`. All elements in `input` must be complex numbers of the form \$a + bj\$, where *a* is the real part and *b* is the imaginary part.

The argument returned by this operation is of the form \$atan2(b, a)\$.

For example:

``` # tensor 'input' is [-2.25 + 4.75j, 3.25 + 5.75j] tf.angle(input) ==> [2.0132, 1.056] ```

@compatibility(numpy) Equivalent to np.angle. @end_compatibility

func AnonymousIterator ¶ added in v1.11.0

func AnonymousIterator(scope *Scope, output_types []tf.DataType, output_shapes []tf.Shape) (handle tf.Output)

A container for an iterator resource.

Returns A handle to the iterator that can be passed to a "MakeIterator" or "IteratorGetNext" op. In contrast to Iterator, AnonymousIterator prevents resource sharing by name, and does not keep a reference to the resource container.

func AnonymousIteratorV2 ¶ added in v1.12.1

func AnonymousIteratorV2(scope *Scope, output_types []tf.DataType, output_shapes []tf.Shape) (handle tf.Output, deleter tf.Output)

A container for an iterator resource.

func AudioSpectrogram ¶ added in v1.2.0

func AudioSpectrogram(scope *Scope, input tf.Output, window_size int64, stride int64, optional ...AudioSpectrogramAttr) (spectrogram tf.Output)

Produces a visualization of audio data over time.

Spectrograms are a standard way of representing audio information as a series of slices of frequency information, one slice for each window of time. By joining these together into a sequence, they form a distinctive fingerprint of the sound over time.

This op expects to receive audio data as an input, stored as floats in the range -1 to 1, together with a window width in samples, and a stride specifying how far to move the window between slices. From this it generates a three dimensional output. The first dimension is for the channels in the input, so a stereo audio input would have two here for example. The second dimension is time, with successive frequency slices. The third dimension has an amplitude value for each frequency during that time slice.

This means the layout when converted and saved as an image is rotated 90 degrees clockwise from a typical spectrogram. Time is descending down the Y axis, and the frequency decreases from left to right.

Each value in the result represents the square root of the sum of the real and imaginary parts of an FFT on the current window of samples. In this way, the lowest dimension represents the power of each frequency in the current window, and adjacent windows are concatenated in the next dimension.

To get a more intuitive and visual look at what this operation does, you can run tensorflow/examples/wav_to_spectrogram to read in an audio file and save out the resulting spectrogram as a PNG image.

Arguments:

input: Float representation of audio data.
window_size: How wide the input window is in samples. For the highest efficiency

this should be a power of two, but other values are accepted.

stride: How widely apart the center of adjacent sample windows should be.

Returns 3D representation of the audio frequencies as an image.

func AudioSummary ¶ added in v1.1.0

func BatchToSpaceND ¶ added in v1.1.0

func BatchToSpaceND(scope *Scope, input tf.Output, block_shape tf.Output, crops tf.Output) (output tf.Output)

BatchToSpace for N-D tensors of type T.

This operation reshapes the "batch" dimension 0 into `M + 1` dimensions of shape `block_shape + [batch]`, interleaves these blocks back into the grid defined by the spatial dimensions `[1, ..., M]`, to obtain a result with the same rank as the input. The spatial dimensions of this intermediate result are then optionally cropped according to `crops` to produce the output. This is the reverse of SpaceToBatch. See below for a precise description.

Arguments:

input: N-D with shape `input_shape = [batch] + spatial_shape + remaining_shape`,

where spatial_shape has M dimensions.

	block_shape: 1-D with shape `[M]`, all values must be >= 1.
	crops: 2-D with shape `[M, 2]`, all values must be >= 0.
  `crops[i] = [crop_start, crop_end]` specifies the amount to crop from input
  dimension `i + 1`, which corresponds to spatial dimension `i`.  It is
  required that
  `crop_start[i] + crop_end[i] <= block_shape[i] * input_shape[i + 1]`.

This operation is equivalent to the following steps:

Reshape `input` to `reshaped` of shape: [block_shape[0], ..., block_shape[M-1], batch / prod(block_shape), input_shape[1], ..., input_shape[N-1]]

Permute dimensions of `reshaped` to produce `permuted` of shape [batch / prod(block_shape),
input_shape[1], block_shape[0], ..., input_shape[M], block_shape[M-1],
input_shape[M+1], ..., input_shape[N-1]]

Reshape `permuted` to produce `reshaped_permuted` of shape [batch / prod(block_shape),
input_shape[1] * block_shape[0], ..., input_shape[M] * block_shape[M-1],
input_shape[M+1], ..., input_shape[N-1]]

Crop the start and end of dimensions `[1, ..., M]` of `reshaped_permuted` according to `crops` to produce the output of shape: [batch / prod(block_shape),
input_shape[1] * block_shape[0] - crops[0,0] - crops[0,1], ..., input_shape[M] * block_shape[M-1] - crops[M-1,0] - crops[M-1,1],
input_shape[M+1], ..., input_shape[N-1]]

func Bincount ¶ added in v1.1.0

func Bincount(scope *Scope, arr tf.Output, size tf.Output, weights tf.Output) (bins tf.Output)

Counts the number of occurrences of each value in an integer array.

Outputs a vector with length `size` and the same dtype as `weights`. If `weights` are empty, then index `i` stores the number of times the value `i` is counted in `arr`. If `weights` are non-empty, then index `i` stores the sum of the value in `weights` at each index where the corresponding value in `arr` is `i`.

Values in `arr` outside of the range [0, size) are ignored.

Arguments:

arr: int32 `Tensor`.
size: non-negative int32 scalar `Tensor`.

func Bitcast ¶ added in v1.1.0

func Bitcast(scope *Scope, input tf.Output, type_ tf.DataType) (output tf.Output)

Bitcasts a tensor from one type to another without copying data.

Given a tensor `input`, this operation returns a tensor that has the same buffer data as `input` with datatype `type`.

If the input datatype `T` is larger than the output datatype `type` then the shape changes from [...] to [..., sizeof(`T`)/sizeof(`type`)].

If `T` is smaller than `type`, the operator requires that the rightmost dimension be equal to sizeof(`type`)/sizeof(`T`). The shape then goes from [..., sizeof(`type`)/sizeof(`T`)] to [...].

tf.bitcast() and tf.cast() work differently when real dtype is casted as a complex dtype (e.g. tf.complex64 or tf.complex128) as tf.cast() make imaginary part 0 while tf.bitcast() gives module error. For example,

Example 1: ```python >>> a = [1., 2., 3.] >>> equality_bitcast = tf.bitcast(a,tf.complex128) tensorflow.python.framework.errors_impl.InvalidArgumentError: Cannot bitcast from float to complex128: shape [3] [Op:Bitcast] >>> equality_cast = tf.cast(a,tf.complex128) >>> print(equality_cast) tf.Tensor([1.+0.j 2.+0.j 3.+0.j], shape=(3,), dtype=complex128) ``` Example 2: ```python >>> tf.bitcast(tf.constant(0xffffffff, dtype=tf.uint32), tf.uint8) <tf.Tensor: ... shape=(4,), dtype=uint8, numpy=array([255, 255, 255, 255], dtype=uint8)> ``` Example 3: ```python >>> x = [1., 2., 3.] >>> y = [0., 2., 3.] >>> equality= tf.equal(x,y) >>> equality_cast = tf.cast(equality,tf.float32) >>> equality_bitcast = tf.bitcast(equality_cast,tf.uint8) >>> print(equality) tf.Tensor([False True True], shape=(3,), dtype=bool) >>> print(equality_cast) tf.Tensor([0. 1. 1.], shape=(3,), dtype=float32) >>> print(equality_bitcast) tf.Tensor( [[ 0 0 0 0]

[ 0 0 128 63]
[ 0 0 128 63]], shape=(3, 4), dtype=uint8)

```

*NOTE*: Bitcast is implemented as a low-level cast, so machines with different endian orderings will give different results.

```

In the above example, the input Tensor with the shape of `[1, 3]` is broadcasted to output Tensor with shape of `[3, 3]`.

This operation is useful for Locality-Sensitive-Hashing (LSH) and other algorithms that use hashing approximations of cosine and `L2` distances; codes can be generated from an input via:

```python codebook_size = 50 codebook_bits = codebook_size * 32 codebook = tf.get_variable('codebook', [x.shape[-1].value, codebook_bits],

dtype=x.dtype,
initializer=tf.orthogonal_initializer())

func CropAndResize ¶ added in v1.1.0

func CropAndResize(scope *Scope, image tf.Output, boxes tf.Output, box_ind tf.Output, crop_size tf.Output, optional ...CropAndResizeAttr) (crops tf.Output)

Extracts crops from the input image tensor and resizes them.

Extracts crops from the input image tensor and resizes them using bilinear sampling or nearest neighbor sampling (possibly with aspect ratio change) to a common output size specified by `crop_size`. This is more general than the `crop_to_bounding_box` op which extracts a fixed size slice from the input image and does not allow resizing or aspect ratio change.

Returns a tensor with `crops` from the input `image` at positions defined at the bounding box locations in `boxes`. The cropped boxes are all resized (with bilinear or nearest neighbor interpolation) to a fixed `size = [crop_height, crop_width]`. The result is a 4-D tensor `[num_boxes, crop_height, crop_width, depth]`. The resizing is corner aligned. In particular, if `boxes = [[0, 0, 1, 1]]`, the method will give identical results to using `tf.image.resize_bilinear()` or `tf.image.resize_nearest_neighbor()`(depends on the `method` argument) with `align_corners=True`.

Arguments:

image: A 4-D tensor of shape `[batch, image_height, image_width, depth]`.

Both `image_height` and `image_width` need to be positive.

boxes: A 2-D tensor of shape `[num_boxes, 4]`. The `i`-th row of the tensor

specifies the coordinates of a box in the `box_ind[i]` image and is specified in normalized coordinates `[y1, x1, y2, x2]`. A normalized coordinate value of `y` is mapped to the image coordinate at `y * (image_height - 1)`, so as the `[0, 1]` interval of normalized image height is mapped to `[0, image_height - 1]` in image height coordinates. We do allow `y1` > `y2`, in which case the sampled crop is an up-down flipped version of the original image. The width dimension is treated similarly. Normalized coordinates outside the `[0, 1]` range are allowed, in which case we use `extrapolation_value` to extrapolate the input image values.

box_ind: A 1-D tensor of shape `[num_boxes]` with int32 values in `[0, batch)`.

The value of `box_ind[i]` specifies the image that the `i`-th box refers to.

crop_size: A 1-D tensor of 2 elements, `size = [crop_height, crop_width]`. All

cropped image patches are resized to this size. The aspect ratio of the image content is not preserved. Both `crop_height` and `crop_width` need to be positive.

specifies the coordinates of a box in the `box_ind[i]` image and is specified in normalized coordinates `[y1, x1, y2, x2]`. A normalized coordinate value of `y` is mapped to the image coordinate at `y * (image_height - 1)`, so as the `[0, 1]` interval of normalized image height is mapped to `[0, image_height - 1] in image height coordinates. We do allow y1 > y2, in which case the sampled crop is an up-down flipped version of the original image. The width dimension is treated similarly. Normalized coordinates outside the `[0, 1]` range are allowed, in which case we use `extrapolation_value` to extrapolate the input image values.

box_ind: A 1-D tensor of shape `[num_boxes]` with int32 values in `[0, batch)`.

The value of `box_ind[i]` specifies the image that the `i`-th box refers to.

Computes the RNN from the input and initial states, with respect to the params buffer. Produces one extra output "host_reserved" than CudnnRNN.

rnn_mode: Indicates the type of the RNN model. input_mode: Indicates whether there is a linear projection between the input and

the actual computation before the first layer. 'skip_input' is only allowed
when input_size == num_units; 'auto_select' implies 'skip_input' when
input_size == num_units; otherwise, it implies 'linear_input'.

direction: Indicates whether a bidirectional model will be used. Should be

"unidirectional" or "bidirectional".

dropout: Dropout probability. When set to 0., dropout is disabled. seed: The 1st part of a seed to initialize dropout. seed2: The 2nd part of a seed to initialize dropout. input: A 3-D tensor with the shape of [seq_length, batch_size, input_size]. input_h: A 3-D tensor with the shape of [num_layer * dir, batch_size,

params: A 1-D tensor that contains the weights and biases in an opaque layout.

The size must be created through CudnnRNNParamsSize, and initialized
separately. Note that they might not be compatible across different
generations. So it is a good idea to save and restore

output: A 3-D tensor with the shape of [seq_length, batch_size,

dir * num_units].

output_h: The same shape has input_h. output_c: The same shape as input_c for LSTM. An empty tensor for other models. is_training: Indicates whether this operation is used for inferenece or

training.

reserve_space: An opaque tensor that can be used in backprop calculation. It

is only produced if is_training is true.

func Cumprod ¶ added in v1.1.0

func Cumprod(scope *Scope, x tf.Output, axis tf.Output, optional ...CumprodAttr) (out tf.Output)

Compute the cumulative product of the tensor `x` along `axis`.

By default, this op performs an inclusive cumprod, which means that the first element of the input is identical to the first element of the output:

```python tf.cumprod([a, b, c]) # => [a, a * b, a * b * c] ```

By setting the `exclusive` kwarg to `True`, an exclusive cumprod is performed instead:

```python tf.cumprod([a, b, c], exclusive=True) # => [1, a, a * b] ```

By setting the `reverse` kwarg to `True`, the cumprod is performed in the opposite direction:

```python tf.cumprod([a, b, c], reverse=True) # => [a * b * c, b * c, c] ```

This is more efficient than using separate `tf.reverse` ops.

The `reverse` and `exclusive` kwargs can also be combined:

```python tf.cumprod([a, b, c], exclusive=True, reverse=True) # => [b * c, c, 1] ```

Arguments:

x: A `Tensor`. Must be one of the following types: `float32`, `float64`,

func Cumsum(scope *Scope, x tf.Output, axis tf.Output, optional ...CumsumAttr) (out tf.Output)

Compute the cumulative sum of the tensor `x` along `axis`.

By default, this op performs an inclusive cumsum, which means that the first element of the input is identical to the first element of the output:

```python tf.cumsum([a, b, c]) # => [a, a + b, a + b + c] ```

By setting the `exclusive` kwarg to `True`, an exclusive cumsum is performed instead:

```python tf.cumsum([a, b, c], exclusive=True) # => [0, a, a + b] ```

By setting the `reverse` kwarg to `True`, the cumsum is performed in the opposite direction:

```python tf.cumsum([a, b, c], reverse=True) # => [a + b + c, b + c, c] ```

This is more efficient than using separate `tf.reverse` ops.

The `reverse` and `exclusive` kwargs can also be combined:

```python tf.cumsum([a, b, c], exclusive=True, reverse=True) # => [b + c, c, 0] ```

Arguments:

x: A `Tensor`. Must be one of the following types: `float32`, `float64`,

func DecodeProtoV2 ¶ added in v1.9.0

func DecodeProtoV2(scope *Scope, bytes tf.Output, message_type string, field_names []string, output_types []tf.DataType, optional ...DecodeProtoV2Attr) (sizes tf.Output, values []tf.Output)

The op extracts fields from a serialized protocol buffers message into tensors.

The `decode_proto` op extracts fields from a serialized protocol buffers message into tensors. The fields in `field_names` are decoded and converted to the corresponding `output_types` if possible.

A `message_type` name must be provided to give context for the field names. The actual message descriptor can be looked up either in the linked-in descriptor pool or a filename provided by the caller using the `descriptor_source` attribute.

Each output tensor is a dense tensor. This means that it is padded to hold the largest number of repeated elements seen in the input minibatch. (The shape is also padded by one to prevent zero-sized dimensions). The actual repeat counts for each example in the minibatch can be found in the `sizes` output. In many cases the output of `decode_proto` is fed immediately into tf.squeeze if missing values are not a concern. When using tf.squeeze, always pass the squeeze dimension explicitly to avoid surprises.

For the most part, the mapping between Proto field types and TensorFlow dtypes is straightforward. However, there are a few special cases:

- A proto field that contains a submessage or group can only be converted to `DT_STRING` (the serialized submessage). This is to reduce the complexity of the API. The resulting string can be used as input to another instance of the decode_proto op.

- TensorFlow lacks support for unsigned integers. The ops represent uint64 types as a `DT_INT64` with the same twos-complement bit pattern (the obvious way). Unsigned int32 values can be represented exactly by specifying type `DT_INT64`, or using twos-complement if the caller specifies `DT_INT32` in the `output_types` attribute.

The `descriptor_source` attribute selects a source of protocol descriptors to consult when looking up `message_type`. This may be a filename containing a serialized `FileDescriptorSet` message, or the special value `local://`, in which case only descriptors linked into the code will be searched; the filename can be on any filesystem accessible to TensorFlow.

You can build a `descriptor_source` file using the `--descriptor_set_out` and `--include_imports` options to the protocol compiler `protoc`.

The `local://` database only covers descriptors linked into the code via C++ libraries, not Python imports. You can link in a proto descriptor by creating a cc_library target with alwayslink=1.

Both binary and text proto serializations are supported, and can be chosen using the `format` attribute.

Arguments:

bytes: Tensor of serialized protos with shape `batch_shape`.
message_type: Name of the proto message type to decode.
field_names: List of strings containing proto field names. An extension field can be decoded

by using its full name, e.g. EXT_PACKAGE.EXT_FIELD_NAME.

output_types: List of TF types to use for the respective field in field_names.

Returns Tensor of int32 with shape `[batch_shape, len(field_names)]`. Each entry is the number of values found for the corresponding field. Optional fields may have 0 or 1 values.List of tensors containing values for the corresponding field. `values[i]` has datatype `output_types[i]` and shape `[batch_shape, max(sizes[...,i])]`.

func DecodeRaw ¶ added in v1.1.0

func DecodeRaw(scope *Scope, bytes tf.Output, out_type tf.DataType, optional ...DecodeRawAttr) (output tf.Output)

Arguments:

bytes: All the elements must have the same length.

Returns A Tensor with one more dimension than the input `bytes`. The added dimension will have size equal to the length of the elements of `bytes` divided by the number of bytes to represent `out_type`.

func DecodeWav ¶ added in v1.2.0

func DecodeWav(scope *Scope, contents tf.Output, optional ...DecodeWavAttr) (audio tf.Output, sample_rate tf.Output)

Decode a 16-bit PCM WAV file to a float tensor.

The -32768 to 32767 signed 16-bit values will be scaled to -1.0 to 1.0 in float.

When desired_channels is set, if the input contains fewer channels than this then the last channel will be duplicated to give the requested number, else if the input has more channels than requested then the additional channels will be ignored.

If desired_samples is set, then the audio will be cropped or padded with zeroes to the requested length.

The first output contains a Tensor with the content of the audio samples. The lowest dimension will be the number of channels, and the second will be the number of samples. For example, a ten-sample-long stereo WAV file should give an output shape of [10, 2].

Arguments:

contents: The WAV-encoded audio, usually from a file.

Returns 2-D with shape `[length, channels]`.Scalar holding the sample rate found in the WAV header.

For `set1` and `set2` ranked `n`, this has rank `n` and the same 1st `n-1` dimensions as `set1` and `set2`. The `nth` dimension contains the result of `set_operation` applied to the corresponding `[0...n-1]` dimension of `set`.

Arguments:

func DepthToSpace ¶ added in v1.1.0

func DepthToSpace(scope *Scope, input tf.Output, block_size int64, optional ...DepthToSpaceAttr) (output tf.Output)

DepthToSpace for tensors of type T.

Rearranges data from depth into blocks of spatial data. This is the reverse transformation of SpaceToDepth. More specifically, this op outputs a copy of the input tensor where values from the `depth` dimension are moved in spatial blocks to the `height` and `width` dimensions. The attr `block_size` indicates the input block size and how the data is moved.

Chunks of data of size `block_size * block_size` from depth are rearranged into non-overlapping blocks of size `block_size x block_size`
The width the output tensor is `input_depth * block_size`, whereas the height is `input_height * block_size`.
The Y, X coordinates within each block of the output image are determined by the high order component of the input channel index.
The depth of the input tensor must be divisible by `block_size * block_size`.

The `data_format` attr specifies the layout of the input and output tensors with the following options:

"NHWC": `[ batch, height, width, channels ]`
"NCHW": `[ batch, channels, height, width ]`
"NCHW_VECT_C":
    `qint8 [ batch, channels / 4, height, width, 4 ]`

It is useful to consider the operation as transforming a 6-D Tensor. e.g. for data_format = NHWC,

Each element in the input tensor can be specified via 6 coordinates,
ordered by decreasing memory layout significance as:
n,iY,iX,bY,bX,oC  (where n=batch index, iX, iY means X or Y coordinates
                   within the input image, bX, bY means coordinates
                   within the output block, oC means output channels).
The output would be the input transposed to the following layout:
n,iY,bY,iX,bX,oC

This operation is useful for resizing the activations between convolutions (but keeping all data), e.g. instead of pooling. It is also useful for training purely convolutional models.

For example, given an input of shape `[1, 1, 1, 4]`, data_format = "NHWC" and block_size = 2:

``` x = [[[[1, 2, 3, 4]]]]

```

This operation will output a tensor of shape `[1, 2, 2, 1]`:

```

[[[[1], [2]],
  [[3], [4]]]]

```

Here, the input has a batch of 1 and each batch element has shape `[1, 1, 4]`, the corresponding output will have 2x2 elements and will have a depth of 1 channel (1 = `4 / (block_size * block_size)`). The output element shape is `[2, 2, 1]`.

For an input tensor with larger depth, here of shape `[1, 1, 1, 12]`, e.g.

``` x = [[[[1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12]]]] ```

This operation, for block size of 2, will return the following tensor of shape `[1, 2, 2, 3]`

```

[[[[1, 2, 3], [4, 5, 6]],
  [[7, 8, 9], [10, 11, 12]]]]

```

Similarly, for the following input of shape `[1 2 2 4]`, and a block size of 2:

 [5, 6, 7, 8]],
[[9, 10, 11, 12],
 [13, 14, 15, 16]]]]

```

the operator will return the following tensor of shape `[1 4 4 1]`:

``` x = [[[ [1], [2], [5], [6]],

[ [3],   [4],  [7],  [8]],
[ [9],  [10], [13],  [14]],

func DepthwiseConv2dNative ¶ added in v1.1.0

func DepthwiseConv2dNative(scope *Scope, input tf.Output, filter tf.Output, strides []int64, padding string, optional ...DepthwiseConv2dNativeAttr) (output tf.Output)

Computes a 2-D depthwise convolution given 4-D `input` and `filter` tensors.

Given an input tensor of shape `[batch, in_height, in_width, in_channels]` and a filter / kernel tensor of shape `[filter_height, filter_width, in_channels, channel_multiplier]`, containing `in_channels` convolutional filters of depth 1, `depthwise_conv2d` applies a different filter to each input channel (expanding from 1 channel to `channel_multiplier` channels for each), then concatenates the results together. Thus, the output has `in_channels * channel_multiplier` channels.

``` for k in 0..in_channels-1

for q in 0..channel_multiplier-1
  output[b, i, j, k * channel_multiplier + q] =
    sum_{di, dj} input[b, strides[1] * i + di, strides[2] * j + dj, k] *
                      filter[di, dj, k, q]

```

Must have `strides[0] = strides[3] = 1`. For the most common case of the same horizontal and vertices strides, `strides = [1, stride, stride, 1]`.

Arguments:

strides: 1-D of length 4.  The stride of the sliding window for each dimension

of `input`.

padding: The type of padding algorithm to use.

func DepthwiseConv2dNativeBackpropFilter ¶ added in v1.1.0

func DepthwiseConv2dNativeBackpropFilter(scope *Scope, input tf.Output, filter_sizes tf.Output, out_backprop tf.Output, strides []int64, padding string, optional ...DepthwiseConv2dNativeBackpropFilterAttr) (output tf.Output)

Computes the gradients of depthwise convolution with respect to the filter.

Arguments:

input: 4-D with shape based on `data_format`.  For example, if

`data_format` is 'NHWC' then `input` is a 4-D `[batch, in_height, in_width, in_channels]` tensor.

filter_sizes: An integer vector representing the tensor shape of `filter`,

where `filter` is a 4-D `[filter_height, filter_width, in_channels, depthwise_multiplier]` tensor.

For example, if `data_format` is 'NHWC' then out_backprop shape is `[batch, out_height, out_width, out_channels]`. Gradients w.r.t. the output of the convolution.

strides: The stride of the sliding window for each dimension of the input

of the convolution.

padding: The type of padding algorithm to use.

Returns 4-D with shape `[filter_height, filter_width, in_channels, out_channels]`. Gradient w.r.t. the `filter` input of the convolution.

func DepthwiseConv2dNativeBackpropInput ¶ added in v1.1.0

func DepthwiseConv2dNativeBackpropInput(scope *Scope, input_sizes tf.Output, filter tf.Output, out_backprop tf.Output, strides []int64, padding string, optional ...DepthwiseConv2dNativeBackpropInputAttr) (output tf.Output)

Computes the gradients of depthwise convolution with respect to the input.

Arguments:

input_sizes: An integer vector representing the shape of `input`, based

on `data_format`. For example, if `data_format` is 'NHWC' then

 `input` is a 4-D `[batch, height, width, channels]` tensor.
	filter: 4-D with shape

`[filter_height, filter_width, in_channels, depthwise_multiplier]`.

out_backprop: 4-D with shape  based on `data_format`.

For example, if `data_format` is 'NHWC' then out_backprop shape is `[batch, out_height, out_width, out_channels]`. Gradients w.r.t. the output of the convolution.

strides: The stride of the sliding window for each dimension of the input

of the convolution.

padding: The type of padding algorithm to use.

Returns 4-D with shape according to `data_format`. For example, if `data_format` is 'NHWC', output shape is `[batch, in_height, in_width, in_channels]`. Gradient w.r.t. the input of the convolution.

func Dequantize ¶ added in v1.1.0

func Dequantize(scope *Scope, input tf.Output, min_range tf.Output, max_range tf.Output, optional ...DequantizeAttr) (output tf.Output)

Dequantize the 'input' tensor into a float Tensor.

[min_range, max_range] are scalar floats that specify the range for the 'input' data. The 'mode' attribute controls exactly which calculations are used to convert the float values to their quantized equivalents.

In 'MIN_COMBINED' mode, each value of the tensor will undergo the following:

``` if T == qint8: in[i] += (range(T) + 1)/ 2.0 out[i] = min_range + (in[i]* (max_range - min_range) / range(T)) ``` here `range(T) = numeric_limits<T>::max() - numeric_limits<T>::min()`

*MIN_COMBINED Mode Example*

If the input comes from a QuantizedRelu6, the output type is quint8 (range of 0-255) but the possible range of QuantizedRelu6 is 0-6. The min_range and max_range values are therefore 0.0 and 6.0. Dequantize on quint8 will take each value, cast to float, and multiply by 6 / 255. Note that if quantizedtype is qint8, the operation will additionally add each value by 128 prior to casting.

If the mode is 'MIN_FIRST', then this approach is used:

```c++ num_discrete_values = 1 << (# of bits in T) range_adjust = num_discrete_values / (num_discrete_values - 1) range = (range_max - range_min) * range_adjust range_scale = range / num_discrete_values const double offset_input = static_cast<double>(input) - lowest_quantized; result = range_min + ((input - numeric_limits<T>::min()) * range_scale) ```

*SCALED mode Example*

`SCALED` mode matches the quantization approach used in `QuantizeAndDequantize{V2|V3}`.

If the mode is `SCALED`, we do not use the full range of the output type, choosing to elide the lowest possible value for symmetry (e.g., output range is -127 to 127, not -128 to 127 for signed 8 bit quantization), so that 0.0 maps to 0.

We first find the range of values in our tensor. The range we use is always centered on 0, so we find m such that ```c++

m = max(abs(input_min), abs(input_max))

```

Our input tensor range is then `[-m, m]`.

Next, we choose our fixed-point quantization buckets, `[min_fixed, max_fixed]`. If T is signed, this is ```

num_bits = sizeof(T) * 8
[min_fixed, max_fixed] =
    [-(1 << (num_bits - 1) - 1), (1 << (num_bits - 1)) - 1]

```

Otherwise, if T is unsigned, the fixed-point range is ```

[min_fixed, max_fixed] = [0, (1 << num_bits) - 1]

```

From this we compute our scaling factor, s: ```c++

s = (2 * m) / (max_fixed - min_fixed)

```

Now we can dequantize the elements of our tensor: ```c++ result = input * s ```

Arguments:

min_range: The minimum scalar value possibly produced for the input.
max_range: The maximum scalar value possibly produced for the input.

func DeserializeIterator ¶ added in v1.5.0

func DeserializeIterator(scope *Scope, resource_handle tf.Output, serialized tf.Output) (o *tf.Operation)

Converts the given variant tensor to an iterator and stores it in the given resource.

Arguments:

resource_handle: A handle to an iterator resource.
serialized: A variant tensor storing the state of the iterator contained in the

resource.

Returns the created operation.

func DeserializeManySparse ¶ added in v1.1.0

func DeserializeManySparse(scope *Scope, serialized_sparse tf.Output, dtype tf.DataType) (sparse_indices tf.Output, sparse_values tf.Output, sparse_shape tf.Output)

Deserialize and concatenate `SparseTensors` from a serialized minibatch.

The input `serialized_sparse` must be a string matrix of shape `[N x 3]` where `N` is the minibatch size and the rows correspond to packed outputs of `SerializeSparse`. The ranks of the original `SparseTensor` objects must all match. When the final `SparseTensor` is created, it has rank one higher than the ranks of the incoming `SparseTensor` objects (they have been concatenated along a new row dimension).

The output `SparseTensor` object's shape values for all dimensions but the first are the max across the input `SparseTensor` objects' shape values for the corresponding dimensions. Its first shape value is `N`, the minibatch size.

The input `SparseTensor` objects' indices are assumed ordered in standard lexicographic order. If this is not the case, after this step run `SparseReorder` to restore index ordering.

For example, if the serialized input is a `[2 x 3]` matrix representing two original `SparseTensor` objects:

index = [ 0]
        [10]
        [20]
values = [1, 2, 3]
shape = [50]

and

index = [ 2]
        [10]
values = [4, 5]
shape = [30]

then the final deserialized `SparseTensor` will be:

index = [0  0]
        [0 10]
        [0 20]
        [1  2]
        [1 10]
values = [1, 2, 3, 4, 5]
shape = [2 50]

Arguments:

serialized_sparse: 2-D, The `N` serialized `SparseTensor` objects.

Must have 3 columns.

dtype: The `dtype` of the serialized `SparseTensor` objects.

func DeserializeSparse ¶ added in v1.5.0

func DeserializeSparse(scope *Scope, serialized_sparse tf.Output, dtype tf.DataType) (sparse_indices tf.Output, sparse_values tf.Output, sparse_shape tf.Output)

Deserialize `SparseTensor` objects.

The input `serialized_sparse` must have the shape `[?, ?, ..., ?, 3]` where the last dimension stores serialized `SparseTensor` objects and the other N dimensions (N >= 0) correspond to a batch. The ranks of the original `SparseTensor` objects must all match. When the final `SparseTensor` is created, its rank is the rank of the incoming `SparseTensor` objects plus N; the sparse tensors have been concatenated along new dimensions, one for each batch.

The output `SparseTensor` object's shape values for the original dimensions are the max across the input `SparseTensor` objects' shape values for the corresponding dimensions. The new dimensions match the size of the batch.

The input `SparseTensor` objects' indices are assumed ordered in standard lexicographic order. If this is not the case, after this step run `SparseReorder` to restore index ordering.

For example, if the serialized input is a `[2 x 3]` matrix representing two original `SparseTensor` objects:

index = [ 0]
        [10]
        [20]
values = [1, 2, 3]
shape = [50]

and

index = [ 2]
        [10]
values = [4, 5]
shape = [30]

then the final deserialized `SparseTensor` will be:

index = [0  0]
        [0 10]
        [0 20]
        [1  2]
        [1 10]
values = [1, 2, 3, 4, 5]
shape = [2 50]

Arguments:

serialized_sparse: The serialized `SparseTensor` objects. The last dimension

must have 3 columns.

All subsequent operations using the resource will result in a NotFound error status.

Arguments:

resource: handle to the resource to delete.

Returns the created operation.

func Diag ¶ added in v1.1.0

func Diag(scope *Scope, diagonal tf.Output) (output tf.Output)

Returns a diagonal tensor with a given diagonal values.

Given a `diagonal`, this operation returns a tensor with the `diagonal` and everything else padded with zeros. The diagonal is computed as follows:

Assume `diagonal` has dimensions [D1,..., Dk], then the output is a tensor of rank 2k with dimensions [D1,..., Dk, D1,..., Dk] where:

`output[i1,..., ik, i1,..., ik] = diagonal[i1, ..., ik]` and 0 everywhere else.

For example:

``` # 'diagonal' is [1, 2, 3, 4] tf.diag(diagonal) ==> [[1, 0, 0, 0]

[0, 2, 0, 0]
[0, 0, 3, 0]
[0, 0, 0, 4]]

```

Arguments:

diagonal: Rank k tensor where k is at most 1.

func DiagPart ¶ added in v1.1.0

func DiagPart(scope *Scope, input tf.Output) (diagonal tf.Output)

Returns the diagonal part of the tensor.

This operation returns a tensor with the `diagonal` part of the `input`. The `diagonal` part is computed as follows:

Assume `input` has dimensions `[D1,..., Dk, D1,..., Dk]`, then the output is a tensor of rank `k` with dimensions `[D1,..., Dk]` where:

`diagonal[i1,..., ik] = input[i1, ..., ik, i1,..., ik]`.

For example:

``` # 'input' is [[1, 0, 0, 0]

[0, 2, 0, 0]
[0, 0, 3, 0]
[0, 0, 0, 4]]

tf.diag_part(input) ==> [1, 2, 3, 4] ```

Returns The extracted diagonal.

func Digamma ¶ added in v1.1.0

`Gamma(x)`), element-wise.

func Dilation2D ¶ added in v1.1.0

func Dilation2D(scope *Scope, input tf.Output, filter tf.Output, strides []int64, rates []int64, padding string) (output tf.Output)

Computes the grayscale dilation of 4-D `input` and 3-D `filter` tensors.

The `input` tensor has shape `[batch, in_height, in_width, depth]` and the `filter` tensor has shape `[filter_height, filter_width, depth]`, i.e., each input channel is processed independently of the others with its own structuring function. The `output` tensor has shape `[batch, out_height, out_width, depth]`. The spatial dimensions of the output tensor depend on the `padding` algorithm. We currently only support the default "NHWC" `data_format`.

In detail, the grayscale morphological 2-D dilation is the max-sum correlation (for consistency with `conv2d`, we use unmirrored filters):

output[b, y, x, c] =
   max_{dy, dx} input[b,
                      strides[1] * y + rates[1] * dy,
                      strides[2] * x + rates[2] * dx,
                      c] +
                filter[dy, dx, c]

Max-pooling is a special case when the filter has size equal to the pooling kernel size and contains all zeros.

Note on duality: The dilation of `input` by the `filter` is equal to the negation of the erosion of `-input` by the reflected `filter`.

Arguments:

input: 4-D with shape `[batch, in_height, in_width, depth]`.
filter: 3-D with shape `[filter_height, filter_width, depth]`.
strides: The stride of the sliding window for each dimension of the input

tensor. Must be: `[1, stride_height, stride_width, 1]`.

rates: The input stride for atrous morphological dilation. Must be:

`[1, rate_height, rate_width, 1]`.

func DrawBoundingBoxes ¶ added in v1.1.0

func DrawBoundingBoxes(scope *Scope, images tf.Output, boxes tf.Output) (output tf.Output)

Draw bounding boxes on a batch of images.

Outputs a copy of `images` but draws on top of the pixels zero or more bounding boxes specified by the locations in `boxes`. The coordinates of the each bounding box in `boxes` are encoded as `[y_min, x_min, y_max, x_max]`. The bounding box coordinates are floats in `[0.0, 1.0]` relative to the width and height of the underlying image.

For example, if an image is 100 x 200 pixels (height x width) and the bounding box is `[0.1, 0.2, 0.5, 0.9]`, the upper-left and bottom-right coordinates of the bounding box will be `(40, 10)` to `(180, 50)` (in (x,y) coordinates).

Parts of the bounding box may fall outside the image.

Arguments:

func DrawBoundingBoxesV2 ¶ added in v1.12.1

func DrawBoundingBoxesV2(scope *Scope, images tf.Output, boxes tf.Output, colors tf.Output) (output tf.Output)

Draw bounding boxes on a batch of images.

Outputs a copy of `images` but draws on top of the pixels zero or more bounding boxes specified by the locations in `boxes`. The coordinates of the each bounding box in `boxes` are encoded as `[y_min, x_min, y_max, x_max]`. The bounding box coordinates are floats in `[0.0, 1.0]` relative to the width and height of the underlying image.

For example, if an image is 100 x 200 pixels (height x width) and the bounding box is `[0.1, 0.2, 0.5, 0.9]`, the upper-left and bottom-right coordinates of the bounding box will be `(40, 10)` to `(100, 50)` (in (x,y) coordinates).

func DynamicPartition ¶ added in v1.1.0

func DynamicPartition(scope *Scope, data tf.Output, partitions tf.Output, num_partitions int64) (outputs []tf.Output)

Partitions `data` into `num_partitions` tensors using indices from `partitions`.

For each index tuple `js` of size `partitions.ndim`, the slice `data[js, ...]` becomes part of `outputs[partitions[js]]`. The slices with `partitions[js] = i` are placed in `outputs[i]` in lexicographic order of `js`, and the first dimension of `outputs[i]` is the number of entries in `partitions` equal to `i`. In detail,

```python

outputs[i].shape = [sum(partitions == i)] + data.shape[partitions.ndim:]

outputs[i] = pack([data[js, ...] for js if partitions[js] == i])

```

`data.shape` must start with `partitions.shape`.

For example:

```python

# Scalar partitions.
partitions = 1
num_partitions = 2
data = [10, 20]
outputs[0] = []  # Empty with shape [0, 2]
outputs[1] = [[10, 20]]

# Vector partitions.
partitions = [0, 0, 1, 1, 0]
num_partitions = 2
data = [10, 20, 30, 40, 50]
outputs[0] = [10, 20, 50]
outputs[1] = [30, 40]

```

See `dynamic_stitch` for an example on how to merge partitions back.

Arguments:

partitions: Any shape.  Indices in the range `[0, num_partitions)`.
num_partitions: The number of partitions to output.

func DynamicStitch ¶ added in v1.1.0

func DynamicStitch(scope *Scope, indices []tf.Output, data []tf.Output) (merged tf.Output)

Interleave the values from the `data` tensors into a single tensor.

Builds a merged tensor such that ¶

```python

merged[indices[m][i, ..., j], ...] = data[m][i, ..., j, ...]

```

For example, if each `indices[m]` is scalar or vector, we have

```python

# Scalar indices:
merged[indices[m], ...] = data[m][...]

# Vector indices:
merged[indices[m][i], ...] = data[m][i, ...]

```

Each `data[i].shape` must start with the corresponding `indices[i].shape`, and the rest of `data[i].shape` must be constant w.r.t. `i`. That is, we must have `data[i].shape = indices[i].shape + constant`. In terms of this `constant`, the output shape is

merged.shape = [max(indices)] + constant

Values are merged in order, so if an index appears in both `indices[m][i]` and `indices[n][j]` for `(m,i) < (n,j)` the slice `data[n][j]` will appear in the merged result. If you do not need this guarantee, ParallelDynamicStitch might perform better on some devices.

For example:

```python

indices[0] = 6
indices[1] = [4, 1]
indices[2] = [[5, 2], [0, 3]]
data[0] = [61, 62]
data[1] = [[41, 42], [11, 12]]
data[2] = [[[51, 52], [21, 22]], [[1, 2], [31, 32]]]
merged = [[1, 2], [11, 12], [21, 22], [31, 32], [41, 42],
          [51, 52], [61, 62]]

```

This method can be used to merge partitions created by `dynamic_partition` as illustrated on the following example:

```python

# Apply function (increments x_i) on elements for which a certain condition
# apply (x_i != -1 in this example).
x=tf.constant([0.1, -1., 5.2, 4.3, -1., 7.4])
condition_mask=tf.not_equal(x,tf.constant(-1.))
partitioned_data = tf.dynamic_partition(
    x, tf.cast(condition_mask, tf.int32) , 2)
partitioned_data[1] = partitioned_data[1] + 1.0
condition_indices = tf.dynamic_partition(
    tf.range(tf.shape(x)[0]), tf.cast(condition_mask, tf.int32) , 2)
x = tf.dynamic_stitch(condition_indices, partitioned_data)
# Here x=[1.1, -1., 6.2, 5.3, -1, 8.4], the -1. values remain
# unchanged.

```

func EncodeProto ¶ added in v1.9.0

func EncodeProto(scope *Scope, sizes tf.Output, values []tf.Output, field_names []string, message_type string, optional ...EncodeProtoAttr) (bytes tf.Output)

The op serializes protobuf messages provided in the input tensors.

The types of the tensors in `values` must match the schema for the fields specified in `field_names`. All the tensors in `values` must have a common shape prefix, *batch_shape*.

The `sizes` tensor specifies repeat counts for each field. The repeat count (last dimension) of a each tensor in `values` must be greater than or equal to corresponding repeat count in `sizes`.

A `message_type` name must be provided to give context for the field names. The actual message descriptor can be looked up either in the linked-in descriptor pool or a filename provided by the caller using the `descriptor_source` attribute.

The `descriptor_source` attribute selects a source of protocol descriptors to consult when looking up `message_type`. This may be a filename containing a serialized `FileDescriptorSet` message, or the special value `local://`, in which case only descriptors linked into the code will be searched; the filename can be on any filesystem accessible to TensorFlow.

You can build a `descriptor_source` file using the `--descriptor_set_out` and `--include_imports` options to the protocol compiler `protoc`.

The `local://` database only covers descriptors linked into the code via C++ libraries, not Python imports. You can link in a proto descriptor by creating a cc_library target with alwayslink=1.

There are a few special cases in the value mapping:

Submessage and group fields must be pre-serialized as TensorFlow strings.

TensorFlow lacks support for unsigned int64s, so they must be represented as `tf.int64` with the same twos-complement bit pattern (the obvious way).

Unsigned int32 values can be represented exactly with `tf.int64`, or with sign wrapping if the input is of type `tf.int32`.

Arguments:

sizes: Tensor of int32 with shape `[batch_shape, len(field_names)]`.
values: List of tensors containing values for the corresponding field.
field_names: List of strings containing proto field names.
message_type: Name of the proto message type to decode.

func ExpandDims ¶ added in v1.1.0

func ExpandDims(scope *Scope, input tf.Output, axis tf.Output) (output tf.Output)

Inserts a dimension of 1 into a tensor's shape.

Given a tensor `input`, this operation inserts a dimension of 1 at the dimension index `axis` of `input`'s shape. The dimension index `axis` starts at zero; if you specify a negative number for `axis` it is counted backward from the end.

This operation is useful if you want to add a batch dimension to a single element. For example, if you have a single image of shape `[height, width, channels]`, you can make it a batch of 1 image with `expand_dims(image, 0)`, which will make the shape `[1, height, width, channels]`.

Other examples:

``` # 't' is a tensor of shape [2] shape(expand_dims(t, 0)) ==> [1, 2] shape(expand_dims(t, 1)) ==> [2, 1] shape(expand_dims(t, -1)) ==> [2, 1]

# 't2' is a tensor of shape [2, 3, 5] shape(expand_dims(t2, 0)) ==> [1, 2, 3, 5] shape(expand_dims(t2, 2)) ==> [2, 3, 1, 5] shape(expand_dims(t2, 3)) ==> [2, 3, 5, 1] ```

This operation requires that:

`-1-input.dims() <= dim <= input.dims()`

This operation is related to `squeeze()`, which removes dimensions of size 1.

Arguments:

axis: 0-D (scalar). Specifies the dimension index at which to

expand the shape of `input`. Must be in the range `[-rank(input) - 1, rank(input)]`.

Returns Contains the same data as `input`, but its shape has an additional dimension of size 1 added.

func FakeParam(scope *Scope, dtype tf.DataType, shape tf.Shape) (output tf.Output)

This op is used as a placeholder in If branch functions. It doesn't provide a
valid output when run, so must either be removed (e.g. replaced with a
function input) or guaranteed not to be used (e.g. if mirroring an
intermediate output needed for the gradient computation of the other branch).

Arguments:

	dtype: The type of the output.
	shape:     The purported shape of the output. This is only used for shape inference;
    the output will not necessarily have this shape. Can be a partial shape.

Returns \"Fake\" output value. This should not be consumed by another op.

func FakeQuantWithMinMaxArgs ¶ added in v1.1.0

func FakeQuantWithMinMaxArgs(scope *Scope, inputs tf.Output, optional ...FakeQuantWithMinMaxArgsAttr) (outputs tf.Output)

Fake-quantize the 'inputs' tensor, type float to 'outputs' tensor of same type.

Attributes `[min; max]` define the clamping range for the `inputs` data. `inputs` values are quantized into the quantization range (`[0; 2^num_bits - 1]` when `narrow_range` is false and `[1; 2^num_bits - 1]` when it is true) and then de-quantized and output as floats in `[min; max]` interval. `num_bits` is the bitwidth of the quantization; between 2 and 16, inclusive.

Before quantization, `min` and `max` values are adjusted with the following logic. It is suggested to have `min <= 0 <= max`. If `0` is not in the range of values, the behavior can be unexpected: If `0 < min < max`: `min_adj = 0` and `max_adj = max - min`. If `min < max < 0`: `min_adj = min - max` and `max_adj = 0`. If `min <= 0 <= max`: `scale = (max - min) / (2^num_bits - 1) `, `min_adj = scale * round(min / scale)` and `max_adj = max + min_adj - min`.

Quantization is called fake since the output is still in floating point.

func FakeQuantWithMinMaxArgsGradient ¶ added in v1.1.0

func FakeQuantWithMinMaxArgsGradient(scope *Scope, gradients tf.Output, inputs tf.Output, optional ...FakeQuantWithMinMaxArgsGradientAttr) (backprops tf.Output)

Compute gradients for a FakeQuantWithMinMaxArgs operation.

Arguments:

gradients: Backpropagated gradients above the FakeQuantWithMinMaxArgs operation.
inputs: Values passed as inputs to the FakeQuantWithMinMaxArgs operation.

Returns Backpropagated gradients below the FakeQuantWithMinMaxArgs operation: `gradients * (inputs >= min && inputs <= max)`.

func FakeQuantWithMinMaxVars ¶ added in v1.1.0

func FakeQuantWithMinMaxVars(scope *Scope, inputs tf.Output, min tf.Output, max tf.Output, optional ...FakeQuantWithMinMaxVarsAttr) (outputs tf.Output)

Fake-quantize the 'inputs' tensor of type float via global float scalars `min`

and `max` to 'outputs' tensor of same shape as `inputs`.

`[min; max]` define the clamping range for the `inputs` data. `inputs` values are quantized into the quantization range (`[0; 2^num_bits - 1]` when `narrow_range` is false and `[1; 2^num_bits - 1]` when it is true) and then de-quantized and output as floats in `[min; max]` interval. `num_bits` is the bitwidth of the quantization; between 2 and 16, inclusive.

Before quantization, `min` and `max` values are adjusted with the following logic. It is suggested to have `min <= 0 <= max`. If `0` is not in the range of values, the behavior can be unexpected: If `0 < min < max`: `min_adj = 0` and `max_adj = max - min`. If `min < max < 0`: `min_adj = min - max` and `max_adj = 0`. If `min <= 0 <= max`: `scale = (max - min) / (2^num_bits - 1) `, `min_adj = scale * round(min / scale)` and `max_adj = max + min_adj - min`.

This operation has a gradient and thus allows for training `min` and `max` values.

func FakeQuantWithMinMaxVarsGradient ¶ added in v1.1.0

func FakeQuantWithMinMaxVarsGradient(scope *Scope, gradients tf.Output, inputs tf.Output, min tf.Output, max tf.Output, optional ...FakeQuantWithMinMaxVarsGradientAttr) (backprops_wrt_input tf.Output, backprop_wrt_min tf.Output, backprop_wrt_max tf.Output)

Arguments:

gradients: Backpropagated gradients above the FakeQuantWithMinMaxVars operation.
inputs: Values passed as inputs to the FakeQuantWithMinMaxVars operation.

min, max: Quantization interval, scalar floats.

Returns Backpropagated gradients w.r.t. inputs: `gradients * (inputs >= min && inputs <= max)`.Backpropagated gradients w.r.t. min parameter: `sum(gradients * (inputs < min))`.Backpropagated gradients w.r.t. max parameter: `sum(gradients * (inputs > max))`.

func FakeQuantWithMinMaxVarsPerChannel ¶ added in v1.1.0

func FakeQuantWithMinMaxVarsPerChannel(scope *Scope, inputs tf.Output, min tf.Output, max tf.Output, optional ...FakeQuantWithMinMaxVarsPerChannelAttr) (outputs tf.Output)

Fake-quantize the 'inputs' tensor of type float and one of the shapes: `[d]`,

`[b, d]` `[b, h, w, d]` via per-channel floats `min` and `max` of shape `[d]` to 'outputs' tensor of same shape as `inputs`.

`[min; max]` define the clamping range for the `inputs` data. `inputs` values are quantized into the quantization range (`[0; 2^num_bits - 1]` when `narrow_range` is false and `[1; 2^num_bits - 1]` when it is true) and then de-quantized and output as floats in `[min; max]` interval. `num_bits` is the bitwidth of the quantization; between 2 and 16, inclusive.

Before quantization, `min` and `max` values are adjusted with the following logic. It is suggested to have `min <= 0 <= max`. If `0` is not in the range of values, the behavior can be unexpected: If `0 < min < max`: `min_adj = 0` and `max_adj = max - min`. If `min < max < 0`: `min_adj = min - max` and `max_adj = 0`. If `min <= 0 <= max`: `scale = (max - min) / (2^num_bits - 1) `, `min_adj = scale * round(min / scale)` and `max_adj = max + min_adj - min`.

This operation has a gradient and thus allows for training `min` and `max` values.

func FakeQuantWithMinMaxVarsPerChannelGradient ¶ added in v1.1.0

func FakeQuantWithMinMaxVarsPerChannelGradient(scope *Scope, gradients tf.Output, inputs tf.Output, min tf.Output, max tf.Output, optional ...FakeQuantWithMinMaxVarsPerChannelGradientAttr) (backprops_wrt_input tf.Output, backprop_wrt_min tf.Output, backprop_wrt_max tf.Output)

Compute gradients for a FakeQuantWithMinMaxVarsPerChannel operation.

Arguments:

gradients: Backpropagated gradients above the FakeQuantWithMinMaxVars operation,

shape one of: `[d]`, `[b, d]`, `[b, h, w, d]`.

	inputs: Values passed as inputs to the FakeQuantWithMinMaxVars operation, shape
  same as `gradients`.

min, max: Quantization interval, floats of shape `[d]`.

Returns Backpropagated gradients w.r.t. inputs, shape same as `inputs`:

`gradients * (inputs >= min && inputs <= max)`.Backpropagated gradients w.r.t. min parameter, shape `[d]`:

`sum_per_d(gradients * (inputs < min))`.Backpropagated gradients w.r.t. max parameter, shape `[d]`: `sum_per_d(gradients * (inputs > max))`.

func Fill ¶ added in v1.1.0

func Fill(scope *Scope, dims tf.Output, value tf.Output) (output tf.Output)

Creates a tensor filled with a scalar value.

This operation creates a tensor of shape `dims` and fills it with `value`.

For example:

``` # Output tensor has shape [2, 3]. fill([2, 3], 9) ==> [[9, 9, 9]

[9, 9, 9]]

```

`tf.fill` differs from `tf.constant` in a few ways:

`tf.fill` only supports scalar contents, whereas `tf.constant` supports Tensor values.
`tf.fill` creates an Op in the computation graph that constructs the actual Tensor value at runtime. This is in contrast to `tf.constant` which embeds the entire Tensor into the graph with a `Const` node.
Because `tf.fill` evaluates at graph runtime, it supports dynamic shapes based on other runtime Tensors, unlike `tf.constant`.

Arguments:

dims: 1-D. Represents the shape of the output tensor.
value: 0-D (scalar). Value to fill the returned tensor.

@compatibility(numpy) Equivalent to np.full @end_compatibility

func FilterByLastComponentDataset ¶ added in v1.12.0

func FilterByLastComponentDataset(scope *Scope, input_dataset tf.Output, output_types []tf.DataType, output_shapes []tf.Shape) (output tf.Output)

Creates a dataset containing elements of first component of `input_dataset` having true in the last component.

func Fingerprint ¶ added in v1.14.0

func Fingerprint(scope *Scope, data tf.Output, method tf.Output) (fingerprint tf.Output)

Generates fingerprint values.

Generates fingerprint values of `data`.

Fingerprint op considers the first dimension of `data` as the batch dimension, and `output[i]` contains the fingerprint value generated from contents in `data[i, ...]` for all `i`.

Fingerprint op writes fingerprint values as byte arrays. For example, the default method `farmhash64` generates a 64-bit fingerprint value at a time. This 8-byte value is written out as an `uint8` array of size 8, in little-endian order.

For example, suppose that `data` has data type `DT_INT32` and shape (2, 3, 4), and that the fingerprint method is `farmhash64`. In this case, the output shape is (2, 8), where 2 is the batch dimension size of `data`, and 8 is the size of each fingerprint value in bytes. `output[0, :]` is generated from 12 integers in `data[0, :, :]` and similarly `output[1, :]` is generated from other 12 integers in `data[1, :, :]`.

Note that this op fingerprints the raw underlying buffer, and it does not fingerprint Tensor's metadata such as data type and/or shape. For example, the fingerprint values are invariant under reshapes and bitcasts as long as the batch dimension remain the same:

``` Fingerprint(data) == Fingerprint(Reshape(data, ...)) Fingerprint(data) == Fingerprint(Bitcast(data, ...)) ```

For string data, one should expect `Fingerprint(data) != Fingerprint(ReduceJoin(data))` in general.

Arguments:

data: Must have rank 1 or higher.
method: Fingerprint method used by this op. Currently available method is

`farmhash::fingerprint64`.

Returns A two-dimensional `Tensor` of type `tf.uint8`. The first dimension equals to `data`'s first dimension, and the second dimension size depends on the fingerprint algorithm.

func FixedLengthRecordDataset ¶ added in v1.2.0

func FixedLengthRecordDataset(scope *Scope, filenames tf.Output, header_bytes tf.Output, record_bytes tf.Output, footer_bytes tf.Output, buffer_size tf.Output) (handle tf.Output)

Creates a dataset that emits the records from one or more binary files.

Arguments:

filenames: A scalar or a vector containing the name(s) of the file(s) to be

read.

header_bytes: A scalar representing the number of bytes to skip at the

beginning of a file.

record_bytes: A scalar representing the number of bytes in each record.
footer_bytes: A scalar representing the number of bytes to skip at the end

of a file.

func FixedLengthRecordReaderV2 ¶ added in v1.1.0

func FixedLengthRecordReaderV2(scope *Scope, record_bytes int64, optional ...FixedLengthRecordReaderV2Attr) (reader_handle tf.Output)

Arguments:

record_bytes: Number of bytes in the record.

Returns The handle to reference the Reader.

func FixedUnigramCandidateSampler ¶ added in v1.1.0

func FixedUnigramCandidateSampler(scope *Scope, true_classes tf.Output, num_true int64, num_sampled int64, unique bool, range_max int64, optional ...FixedUnigramCandidateSamplerAttr) (sampled_candidates tf.Output, true_expected_count tf.Output, sampled_expected_count tf.Output)

Generates labels for candidate sampling with a learned unigram distribution.

A unigram sampler could use a fixed unigram distribution read from a file or passed in as an in-memory array instead of building up the distribution from data on the fly. There is also an option to skew the distribution by applying a distortion power to the weights.

The vocabulary file should be in CSV-like format, with the last field being the weight associated with the word.

For each batch, this op picks a single set of sampled candidate labels.

The advantages of sampling candidates per-batch are simplicity and the possibility of efficient dense matrix multiplication. The disadvantage is that the sampled candidates must be chosen independently of the context and of the true labels.

Arguments:

true_classes: A batch_size * num_true matrix, in which each row contains the

IDs of the num_true target_classes in the corresponding original label.

num_true: Number of true labels per context.
num_sampled: Number of candidates to randomly sample.
unique: If unique is true, we sample with rejection, so that all sampled

candidates in a batch are unique. This requires some approximation to estimate the post-rejection sampling probabilities.

range_max: The sampler will sample integers from the interval [0, range_max).

Returns A vector of length num_sampled, in which each element is the ID of a sampled candidate.A batch_size * num_true matrix, representing the number of times each candidate is expected to occur in a batch of sampled candidates. If unique=true, then this is a probability.A vector of length num_sampled, for each sampled candidate representing the number of times the candidate is expected to occur in a batch of sampled candidates.

func FloorMod ¶ added in v1.1.0

func FloorMod(scope *Scope, x tf.Output, y tf.Output) (z tf.Output)

Returns element-wise remainder of division. When `x < 0` xor `y < 0` is

true, this follows Python semantics in that the result here is consistent with a flooring divide. E.g. `floor(x / y) * y + mod(x, y) = x`.

*NOTE*: `FloorMod` supports broadcasting. More about broadcasting [here](http://docs.scipy.org/doc/numpy/user/basics.broadcasting.html)

func FractionalAvgPool ¶ added in v1.1.0

func FractionalAvgPool(scope *Scope, value tf.Output, pooling_ratio []float32, optional ...FractionalAvgPoolAttr) (output tf.Output, row_pooling_sequence tf.Output, col_pooling_sequence tf.Output)

Performs fractional average pooling on the input.

Fractional average pooling is similar to Fractional max pooling in the pooling region generation step. The only difference is that after pooling regions are generated, a mean operation is performed instead of a max operation in each pooling region.

Arguments:

value: 4-D with shape `[batch, height, width, channels]`.
pooling_ratio: Pooling ratio for each dimension of `value`, currently only

supports row and col dimension and should be >= 1.0. For example, a valid pooling ratio looks like [1.0, 1.44, 1.73, 1.0]. The first and last elements must be 1.0 because we don't allow pooling on batch and channels dimensions. 1.44 and 1.73 are pooling ratio on height and width dimensions respectively.

Returns output tensor after fractional avg pooling.row pooling sequence, needed to calculate gradient.column pooling sequence, needed to calculate gradient.

func FractionalAvgPoolGrad ¶ added in v1.1.0

func FractionalAvgPoolGrad(scope *Scope, orig_input_tensor_shape tf.Output, out_backprop tf.Output, row_pooling_sequence tf.Output, col_pooling_sequence tf.Output, optional ...FractionalAvgPoolGradAttr) (output tf.Output)

Computes gradient of the FractionalAvgPool function.

Unlike FractionalMaxPoolGrad, we don't need to find arg_max for FractionalAvgPoolGrad, we just need to evenly back-propagate each element of out_backprop to those indices that form the same pooling cell. Therefore, we just need to know the shape of original input tensor, instead of the whole tensor.

Arguments:

orig_input_tensor_shape: Original input tensor shape for `fractional_avg_pool`
out_backprop: 4-D with shape `[batch, height, width, channels]`.  Gradients

w.r.t. the output of `fractional_avg_pool`.

row_pooling_sequence: row pooling sequence, form pooling region with

col_pooling_sequence.

col_pooling_sequence: column pooling sequence, form pooling region with

row_pooling sequence.

Returns 4-D. Gradients w.r.t. the input of `fractional_avg_pool`.

func FractionalMaxPool ¶ added in v1.1.0

func FractionalMaxPool(scope *Scope, value tf.Output, pooling_ratio []float32, optional ...FractionalMaxPoolAttr) (output tf.Output, row_pooling_sequence tf.Output, col_pooling_sequence tf.Output)

Performs fractional max pooling on the input.

Fractional max pooling is slightly different than regular max pooling. In regular max pooling, you downsize an input set by taking the maximum value of smaller N x N subsections of the set (often 2x2), and try to reduce the set by a factor of N, where N is an integer. Fractional max pooling, as you might expect from the word "fractional", means that the overall reduction ratio N does not have to be an integer.

The sizes of the pooling regions are generated randomly but are fairly uniform. For example, let's look at the height dimension, and the constraints on the list of rows that will be pool boundaries.

First we define the following:

1. input_row_length : the number of rows from the input set 2. output_row_length : which will be smaller than the input 3. alpha = input_row_length / output_row_length : our reduction ratio 4. K = floor(alpha) 5. row_pooling_sequence : this is the result list of pool boundary rows

Then, row_pooling_sequence should satisfy:

1. a[0] = 0 : the first value of the sequence is 0 2. a[end] = input_row_length : the last value of the sequence is the size 3. K <= (a[i+1] - a[i]) <= K+1 : all intervals are K or K+1 size 4. length(row_pooling_sequence) = output_row_length+1

For more details on fractional max pooling, see this paper: [Benjamin Graham, Fractional Max-Pooling](http://arxiv.org/abs/1412.6071)

Arguments:

value: 4-D with shape `[batch, height, width, channels]`.
pooling_ratio: Pooling ratio for each dimension of `value`, currently only

supports row and col dimension and should be >= 1.0. For example, a valid pooling ratio looks like [1.0, 1.44, 1.73, 1.0]. The first and last elements must be 1.0 because we don't allow pooling on batch and channels dimensions. 1.44 and 1.73 are pooling ratio on height and width dimensions respectively.

Returns output tensor after fractional max pooling.row pooling sequence, needed to calculate gradient.column pooling sequence, needed to calculate gradient.

Arguments:

col_pooling_sequence.

col_pooling_sequence: column pooling sequence, form pooling region with

row_pooling sequence.

Returns 4-D. Gradients w.r.t. the input of `fractional_max_pool`.

func FusedPadConv2D ¶ added in v1.1.0

func FusedPadConv2D(scope *Scope, input tf.Output, paddings tf.Output, filter tf.Output, mode string, strides []int64, padding string) (output tf.Output)

Performs a padding as a preprocess during a convolution.

Similar to FusedResizeAndPadConv2d, this op allows for an optimized implementation where the spatial padding transformation stage is fused with the im2col lookup, but in this case without the bilinear filtering required for resizing. Fusing the padding prevents the need to write out the intermediate results as whole tensors, reducing memory pressure, and we can get some latency gains by merging the transformation calculations. The data_format attribute for Conv2D isn't supported by this op, and 'NHWC' order is used instead. Internally this op uses a single per-graph scratch buffer, which means that it will block if multiple versions are being run in parallel. This is because this operator is primarily an optimization to minimize memory usage.

Arguments:

input: 4-D with shape `[batch, in_height, in_width, in_channels]`.
paddings: A two-column matrix specifying the padding sizes. The number of

rows must be the same as the rank of `input`.

filter: 4-D with shape

`[filter_height, filter_width, in_channels, out_channels]`.

strides: 1-D of length 4.  The stride of the sliding window for each dimension

of `input`. Must be in the same order as the dimension specified with format.

padding: The type of padding algorithm to use.

func FusedResizeAndPadConv2D ¶ added in v1.1.0

func FusedResizeAndPadConv2D(scope *Scope, input tf.Output, size tf.Output, paddings tf.Output, filter tf.Output, mode string, strides []int64, padding string, optional ...FusedResizeAndPadConv2DAttr) (output tf.Output)

Performs a resize and padding as a preprocess during a convolution.

It's often possible to do spatial transformations more efficiently as part of the packing stage of a convolution, so this op allows for an optimized implementation where these stages are fused together. This prevents the need to write out the intermediate results as whole tensors, reducing memory pressure, and we can get some latency gains by merging the transformation calculations. The data_format attribute for Conv2D isn't supported by this op, and defaults to 'NHWC' order. Internally this op uses a single per-graph scratch buffer, which means that it will block if multiple versions are being run in parallel. This is because this operator is primarily an optimization to minimize memory usage.

Arguments:

input: 4-D with shape `[batch, in_height, in_width, in_channels]`.
size: A 1-D int32 Tensor of 2 elements: `new_height, new_width`.  The

new size for the images.

paddings: A two-column matrix specifying the padding sizes. The number of

rows must be the same as the rank of `input`.

filter: 4-D with shape

`[filter_height, filter_width, in_channels, out_channels]`.

strides: 1-D of length 4.  The stride of the sliding window for each dimension

of `input`. Must be in the same order as the dimension specified with format.

padding: The type of padding algorithm to use.

func Gather ¶ added in v1.1.0

func Gather(scope *Scope, params tf.Output, indices tf.Output, optional ...GatherAttr) (output tf.Output)

Gather slices from `params` according to `indices`.

`indices` must be an integer tensor of any dimension (usually 0-D or 1-D). Produces an output tensor with shape `indices.shape + params.shape[1:]` where:

```python

# Scalar indices
output[:, ..., :] = params[indices, :, ... :]

# Vector indices
output[i, :, ..., :] = params[indices[i], :, ... :]

# Higher rank indices
output[i, ..., j, :, ... :] = params[indices[i, ..., j], :, ..., :]

```

If `indices` is a permutation and `len(indices) == params.shape[0]` then this operation will permute `params` accordingly.

`validate_indices`: DEPRECATED. If this operation is assigned to CPU, values in `indices` are always validated to be within range. If assigned to GPU, out-of-bound indices result in safe but unspecified behavior, which may include raising an error.

func GatherNd ¶ added in v1.1.0

func GatherNd(scope *Scope, params tf.Output, indices tf.Output) (output tf.Output)

Gather slices from `params` into a Tensor with shape specified by `indices`.

`indices` is an K-dimensional integer tensor, best thought of as a (K-1)-dimensional tensor of indices into `params`, where each element defines a slice of `params`:

output[\\(i_0, ..., i_{K-2}\\)] = params[indices[\\(i_0, ..., i_{K-2}\\)]]

Whereas in `tf.gather` `indices` defines slices into the first dimension of `params`, in `tf.gather_nd`, `indices` defines slices into the first `N` dimensions of `params`, where `N = indices.shape[-1]`.

The last dimension of `indices` can be at most the rank of `params`:

indices.shape[-1] <= params.rank

The last dimension of `indices` corresponds to elements (if `indices.shape[-1] == params.rank`) or slices (if `indices.shape[-1] < params.rank`) along dimension `indices.shape[-1]` of `params`. The output tensor has shape

indices.shape[:-1] + params.shape[indices.shape[-1]:]

Note that on CPU, if an out of bound index is found, an error is returned. On GPU, if an out of bound index is found, a 0 is stored in the corresponding output value.

Some examples below.

```python

indices = [[0, 0], [1, 1]]

output = [[['a1', 'b1'], ['c1', 'd1']]]

indices = [[0, 1], [1, 0]]
params = [[['a0', 'b0'], ['c0', 'd0']],
          [['a1', 'b1'], ['c1', 'd1']]]
output = [['c0', 'd0'], ['a1', 'b1']]

indices = [[0, 0, 1], [1, 0, 1]]
params = [[['a0', 'b0'], ['c0', 'd0']],
          [['a1', 'b1'], ['c1', 'd1']]]
output = ['b0', 'b1']

```

```python

indices = [[[1]], [[0]]]

output = [[[['a1', 'b1'], ['c1', 'd1']]],
          [[['a0', 'b0'], ['c0', 'd0']]]]

indices = [[[0, 1], [1, 0]], [[0, 0], [1, 1]]]
params = [[['a0', 'b0'], ['c0', 'd0']],
          [['a1', 'b1'], ['c1', 'd1']]]
output = [[['c0', 'd0'], ['a1', 'b1']],
          [['a0', 'b0'], ['c1', 'd1']]]

indices = [[[0, 0, 1], [1, 0, 1]], [[0, 1, 1], [1, 1, 0]]]
params = [[['a0', 'b0'], ['c0', 'd0']],
          [['a1', 'b1'], ['c1', 'd1']]]
output = [['b0', 'b1'], ['d0', 'c1']]

Arguments:

func GatherV2 ¶ added in v1.3.0

func GatherV2(scope *Scope, params tf.Output, indices tf.Output, axis tf.Output, optional ...GatherV2Attr) (output tf.Output)

Gather slices from `params` axis `axis` according to `indices`.

`indices` must be an integer tensor of any dimension (usually 0-D or 1-D). Produces an output tensor with shape `params.shape[:axis] + indices.shape + params.shape[axis + 1:]` where:

```python

# Scalar indices (output is rank(params) - 1).
output[a_0, ..., a_n, b_0, ..., b_n] =
  params[a_0, ..., a_n, indices, b_0, ..., b_n]

# Vector indices (output is rank(params)).
output[a_0, ..., a_n, i, b_0, ..., b_n] =
  params[a_0, ..., a_n, indices[i], b_0, ..., b_n]

# Higher rank indices (output is rank(params) + rank(indices) - 1).
output[a_0, ..., a_n, i, ..., j, b_0, ... b_n] =
  params[a_0, ..., a_n, indices[i, ..., j], b_0, ..., b_n]

```

Note that on CPU, if an out of bound index is found, an error is returned. On GPU, if an out of bound index is found, a 0 is stored in the corresponding output value.

See also `tf.batch_gather` and `tf.gather_nd`.

Arguments:

params: The tensor from which to gather values. Must be at least rank

`axis + 1`.

indices: Index tensor. Must be in range `[0, params.shape[axis])`.
axis: The axis in `params` to gather `indices` from. Defaults to the first

dimension. Supports negative indexes.

func GenerateVocabRemapping ¶ added in v1.4.0

func GenerateVocabRemapping(scope *Scope, new_vocab_file tf.Output, old_vocab_file tf.Output, new_vocab_offset int64, num_new_vocab int64, optional ...GenerateVocabRemappingAttr) (remapping tf.Output, num_present tf.Output)

Given a path to new and old vocabulary files, returns a remapping Tensor of

length `num_new_vocab`, where `remapping[i]` contains the row number in the old vocabulary that corresponds to row `i` in the new vocabulary (starting at line `new_vocab_offset` and up to `num_new_vocab` entities), or `-1` if entry `i` in the new vocabulary is not in the old vocabulary. The old vocabulary is constrained to the first `old_vocab_size` entries if `old_vocab_size` is not the default value of -1.

`num_vocab_offset` enables use in the partitioned variable case, and should generally be set through examining partitioning info. The format of the files should be a text file, with each line containing a single entity within the vocabulary.

For example, with `new_vocab_file` a text file containing each of the following elements on a single line: `[f0, f1, f2, f3]`, old_vocab_file = [f1, f0, f3], `num_new_vocab = 3, new_vocab_offset = 1`, the returned remapping would be `[0, -1, 2]`.

The op also returns a count of how many entries in the new vocabulary were present in the old vocabulary, which is used to calculate the number of values to initialize in a weight matrix remapping

This functionality can be used to remap both row vocabularies (typically, features) and column vocabularies (typically, classes) from TensorFlow checkpoints. Note that the partitioning logic relies on contiguous vocabularies corresponding to div-partitioned variables. Moreover, the underlying remapping uses an IndexTable (as opposed to an inexact CuckooTable), so client code should use the corresponding index_table_from_file() as the FeatureColumn framework does (as opposed to tf.feature_to_id(), which uses a CuckooTable).

Arguments:

new_vocab_file: Path to the new vocab file.
old_vocab_file: Path to the old vocab file.
new_vocab_offset: How many entries into the new vocab file to start reading.
num_new_vocab: Number of entries in the new vocab file to remap.

Returns A Tensor of length num_new_vocab where the element at index i is equal to the old ID that maps to the new ID i. This element is -1 for any new ID that is not found in the old vocabulary.Number of new vocab entries found in old vocab.

\$P(a, x) = gamma(a, x) / Gamma(a) = 1 - Q(a, x)\$

where

\$gamma(a, x) = \\int_{0}^{x} t^{a-1} exp(-t) dt\$

is the lower incomplete Gamma function.

func Imag ¶ added in v1.1.0

func Imag(scope *Scope, input tf.Output, optional ...ImagAttr) (output tf.Output)

Returns the imaginary part of a complex number.

Given a tensor `input` of complex numbers, this operation returns a tensor of type `float` that is the imaginary part of each element in `input`. All elements in `input` must be complex numbers of the form \$a + bj\$, where *a* is the real part and *b* is the imaginary part returned by this operation.

For example:

``` # tensor 'input' is [-2.25 + 4.75j, 3.25 + 5.75j] tf.imag(input) ==> [4.75, 5.75] ```

func ImageSummary ¶ added in v1.1.0

func ImageSummary(scope *Scope, tag tf.Output, tensor tf.Output, optional ...ImageSummaryAttr) (summary tf.Output)

Outputs a `Summary` protocol buffer with images.

The summary has up to `max_images` summary values containing images. The images are built from `tensor` which must be 4-D with shape `[batch_size, height, width, channels]` and where `channels` can be:

* 1: `tensor` is interpreted as Grayscale. * 3: `tensor` is interpreted as RGB. * 4: `tensor` is interpreted as RGBA.

The images have the same number of channels as the input tensor. For float input, the values are normalized one image at a time to fit in the range `[0, 255]`. `uint8` values are unchanged. The op uses two different normalization algorithms:

If the input values are all positive, they are rescaled so the largest one is 255.

If any input value is negative, the values are shifted so input value 0.0 is at 127. They are then rescaled so that either the smallest value is 0, or the largest one is 255.

The `tag` argument is a scalar `Tensor` of type `string`. It is used to build the `tag` of the summary values:

If `max_images` is 1, the summary value tag is '*tag*/image'.
If `max_images` is greater than 1, the summary value tags are generated sequentially as '*tag*/image/0', '*tag*/image/1', etc.

The `bad_color` argument is the color to use in the generated images for non-finite input values. It is a `uint8` 1-D tensor of length `channels`. Each element must be in the range `[0, 255]` (It represents the value of a pixel in the output image). Non-finite values in the input tensor are replaced by this tensor in the output image. The default value is the color red.

Arguments:

tag: Scalar. Used to build the `tag` attribute of the summary values.
tensor: 4-D of shape `[batch_size, height, width, channels]` where

`channels` is 1, 3, or 4.

Returns Scalar. Serialized `Summary` protocol buffer.

Given a list `x` and a list `y`, this operation returns a list `out` that represents all values that are in `x` but not in `y`. The returned list `out` is sorted in the same order that the numbers appear in `x` (duplicates are preserved). This operation also returns a list `idx` that represents the position of each `out` element in `x`. In other words:

`out[i] = x[idx[i]] for i in [0, 1, ..., len(out) - 1]`

For example, given this input:

``` x = [1, 2, 3, 4, 5, 6] y = [1, 3, 5] ```

This operation would return:

``` out ==> [2, 4, 6] idx ==> [1, 3, 5] ```

Arguments:

x: 1-D. Values to keep.
y: 1-D. Values to remove.

Returns 1-D. Values present in `x` but not in `y`.1-D. Positions of `x` values preserved in `out`.

func LoadAndRemapMatrix ¶ added in v1.4.0

func LoadAndRemapMatrix(scope *Scope, ckpt_path tf.Output, old_tensor_name tf.Output, row_remapping tf.Output, col_remapping tf.Output, initializing_values tf.Output, num_rows int64, num_cols int64, optional ...LoadAndRemapMatrixAttr) (output_matrix tf.Output)

Loads a 2-D (matrix) `Tensor` with name `old_tensor_name` from the checkpoint

at `ckpt_path` and potentially reorders its rows and columns using the specified remappings.

Most users should use one of the wrapper initializers (such as `tf.contrib.framework.load_and_remap_matrix_initializer`) instead of this function directly.

The remappings are 1-D tensors with the following properties:

`row_remapping` must have exactly `num_rows` entries. Row `i` of the output matrix will be initialized from the row corresponding to index `row_remapping[i]` in the old `Tensor` from the checkpoint.
`col_remapping` must have either 0 entries (indicating that no column reordering is needed) or `num_cols` entries. If specified, column `j` of the output matrix will be initialized from the column corresponding to index `col_remapping[j]` in the old `Tensor` from the checkpoint.
A value of -1 in either of the remappings signifies a "missing" entry. In that case, values from the `initializing_values` tensor will be used to fill that missing row or column. If `row_remapping` has `r` missing entries and `col_remapping` has `c` missing entries, then the following condition must be true:

`(r * num_cols) + (c * num_rows) - (r * c) == len(initializing_values)`

The remapping tensors can be generated using the GenerateVocabRemapping op.

As an example, with row_remapping = [1, 0, -1], col_remapping = [0, 2, -1], initializing_values = [0.5, -0.5, 0.25, -0.25, 42], and w(i, j) representing the value from row i, column j of the old tensor in the checkpoint, the output matrix will look like the following:

[[w(1, 0), w(1, 2), 0.5],

[w(0, 0),  w(0, 2), -0.5],
[0.25,    -0.25,      42]]

Arguments:

ckpt_path: Path to the TensorFlow checkpoint (version 2, `TensorBundle`) from

which the old matrix `Tensor` will be loaded.

U is a upper triangular matrix of shape `[M, M]` whose entries correspond to the upper triangular part, including the diagonal, of LU.

P represents a permutation matrix encoded as a list of indices each between `0` and `M-1`, inclusive. If P_mat denotes the permutation matrix corresponding to P, then the L, U and P satisfies P_mat * input = L * U.

Arguments:

Assume `input` has `k+1` dimensions `[I, J, K, ..., M, N]` and `diagonal` has `k` dimensions `[I, J, K, ..., min(M, N)]`. Then the output is a tensor of rank `k+1` with dimensions `[I, J, K, ..., M, N]` where:

If `adjoint` is `True` then each output matrix satisfies `adjoint(matrix[..., :, :]) * output[..., :, :] = rhs[..., :, :]`.

Arguments:

rhs: Shape is `[..., M, K]`.

Returns Shape is `[..., M, K]`.

func MatrixSolveLs ¶ added in v1.1.0

func MatrixSolveLs(scope *Scope, matrix tf.Output, rhs tf.Output, l2_regularizer tf.Output, optional ...MatrixSolveLsAttr) (output tf.Output)

Solves one or more linear least-squares problems.

`matrix` is a tensor of shape `[..., M, N]` whose inner-most 2 dimensions form real or complex matrices of size `[M, N]`. `Rhs` is a tensor of the same type as `matrix` and shape `[..., M, K]`. The output is a tensor shape `[..., N, K]` where each output matrix solves each of the equations `matrix[..., :, :]` * `output[..., :, :]` = `rhs[..., :, :]` in the least squares sense.

We use the following notation for (complex) matrix and right-hand sides in the batch:

`matrix`=\$A \in \mathbb{C}^{m \times n}\$, `rhs`=\$B \in \mathbb{C}^{m \times k}\$, `output`=\$X \in \mathbb{C}^{n \times k}\$, `l2_regularizer`=\$\lambda \in \mathbb{R}\$.

If `fast` is `True`, then the solution is computed by solving the normal equations using Cholesky decomposition. Specifically, if \$m \ge n\$ then \$X = (A^H A + \lambda I)^{-1} A^H B\$, which solves the least-squares problem \$X = \mathrm{argmin}_{Z \in \Re^{n \times k} } ||A Z - B||_F^2 + \lambda ||Z||_F^2\$. If \$m \lt n\$ then `output` is computed as \$X = A^H (A A^H + \lambda I)^{-1} B\$, which (for \$\lambda = 0\$) is the minimum-norm solution to the under-determined linear system, i.e. \$X = \mathrm{argmin}_{Z \in \mathbb{C}^{n \times k} } ||Z||_F^2 \$, subject to \$A Z = B\$. Notice that the fast path is only numerically stable when \$A\$ is numerically full rank and has a condition number \$\mathrm{cond}(A) \lt \frac{1}{\sqrt{\epsilon_{mach} } }\$ or \$\lambda\$ is sufficiently large.

If `fast` is `False` an algorithm based on the numerically robust complete orthogonal decomposition is used. This computes the minimum-norm least-squares solution, even when \$A\$ is rank deficient. This path is typically 6-7 times slower than the fast path. If `fast` is `False` then `l2_regularizer` is ignored.

Arguments:

matrix: Shape is `[..., M, N]`.
rhs: Shape is `[..., M, K]`.
l2_regularizer: Scalar tensor.

@compatibility(numpy) Equivalent to np.linalg.lstsq @end_compatibility

func MatrixSquareRoot ¶ added in v1.12.1

func MatrixSquareRoot(scope *Scope, input tf.Output) (output tf.Output)

matmul(sqrtm(A), sqrtm(A)) = A

The input matrix should be invertible. If the input matrix is real, it should have no eigenvalues which are real and negative (pairs of complex conjugate eigenvalues are allowed).

The matrix square root is computed by first reducing the matrix to quasi-triangular form with the real Schur decomposition. The square root of the quasi-triangular matrix is then computed directly. Details of the algorithm can be found in: Nicholas J. Higham, "Computing real square roots of a real matrix", Linear Algebra Appl., 1987.

The input is a tensor of shape `[..., M, M]` whose inner-most 2 dimensions form square matrices. The output is a tensor of the same shape as the input containing the matrix square root for all input submatrices `[..., :, :]`.

Arguments:

input: Shape is `[..., M, M]`.

Returns Shape is `[..., M, M]`.

func MatrixTriangularSolve ¶ added in v1.1.0

func MatrixTriangularSolve(scope *Scope, matrix tf.Output, rhs tf.Output, optional ...MatrixTriangularSolveAttr) (output tf.Output)

Solves systems of linear equations with upper or lower triangular matrices by backsubstitution.

`matrix` is a tensor of shape `[..., M, M]` whose inner-most 2 dimensions form square matrices. If `lower` is `True` then the strictly upper triangular part of each inner-most matrix is assumed to be zero and not accessed. If `lower` is False then the strictly lower triangular part of each inner-most matrix is assumed to be zero and not accessed. `rhs` is a tensor of shape `[..., M, K]`.

The output is a tensor of shape `[..., M, K]`. If `adjoint` is `True` then the innermost matrices in `output` satisfy matrix equations `matrix[..., :, :] * output[..., :, :] = rhs[..., :, :]`. If `adjoint` is `False` then the strictly then the innermost matrices in `output` satisfy matrix equations `adjoint(matrix[..., i, k]) * output[..., k, j] = rhs[..., i, j]`.

a = tf.constant([[3, 0, 0, 0],

[2,  1,  0,  0],

Pads a tensor with mirrored values.

This operation pads a `input` with mirrored values according to the `paddings` you specify. `paddings` is an integer tensor with shape `[n, 2]`, where n is the rank of `input`. For each dimension D of `input`, `paddings[D, 0]` indicates how many values to add before the contents of `input` in that dimension, and `paddings[D, 1]` indicates how many values to add after the contents of `input` in that dimension. Both `paddings[D, 0]` and `paddings[D, 1]` must be no greater than `input.dim_size(D)` (or `input.dim_size(D) - 1`) if `copy_border` is true (if false, respectively).

The padded size of each dimension D of the output is:

`paddings(D, 0) + input.dim_size(D) + paddings(D, 1)`

For example:

``` # 't' is [[1, 2, 3], [4, 5, 6]]. # 'paddings' is [[1, 1]], [2, 2]]. # 'mode' is SYMMETRIC. # rank of 't' is 2. pad(t, paddings) ==> [[2, 1, 1, 2, 3, 3, 2]

[2, 1, 1, 2, 3, 3, 2]
[5, 4, 4, 5, 6, 6, 5]
[5, 4, 4, 5, 6, 6, 5]]

```

Arguments:

input: The input tensor to be padded.
paddings: A two-column matrix specifying the padding sizes. The number of

rows must be the same as the rank of `input`.

mode: Either `REFLECT` or `SYMMETRIC`. In reflect mode the padded regions

do not include the borders, while in symmetric mode the padded regions do include the borders. For example, if `input` is `[1, 2, 3]` and `paddings` is `[0, 2]`, then the output is `[1, 2, 3, 2, 1]` in reflect mode, and it is `[1, 2, 3, 3, 2]` in symmetric mode.

Returns The padded tensor.

func MirrorPadGrad ¶ added in v1.1.0

func MirrorPadGrad(scope *Scope, input tf.Output, paddings tf.Output, mode string) (output tf.Output)

Gradient op for `MirrorPad` op. This op folds a mirror-padded tensor.

This operation folds the padded areas of `input` by `MirrorPad` according to the `paddings` you specify. `paddings` must be the same as `paddings` argument given to the corresponding `MirrorPad` op.

The folded size of each dimension D of the output is:

`input.dim_size(D) - paddings(D, 0) - paddings(D, 1)`

For example:

``` # 't' is [[1, 2, 3], [4, 5, 6], [7, 8, 9]]. # 'paddings' is [[0, 1]], [0, 1]]. # 'mode' is SYMMETRIC. # rank of 't' is 2. pad(t, paddings) ==> [[ 1, 5]

[11, 28]]

```

Arguments:

input: The input tensor to be folded.
paddings: A two-column matrix specifying the padding sizes. The number of

rows must be the same as the rank of `input`.

mode: The mode used in the `MirrorPad` op.

Returns The folded tensor.

func MutexLock ¶ added in v1.9.0

func MutexLock(scope *Scope, mutex tf.Output) (mutex_lock tf.Output)

Locks a mutex resource. The output is the lock. So long as the lock tensor

is alive, any other request to use `MutexLock` with this mutex will wait.

This is particularly useful for creating a critical section when used in conjunction with `MutexLockIdentity`:

```python

mutex = mutex_v2(

shared_name=handle_name, container=container, name=name)

def execute_in_critical_section(fn, *args, **kwargs):

lock = gen_resource_variable_ops.mutex_lock(mutex)

with ops.control_dependencies([lock]):
  r = fn(*args, **kwargs)

with ops.control_dependencies(nest.flatten(r)):
  with ops.colocate_with(mutex):
    ensure_lock_exists = mutex_lock_identity(lock)

  # Make sure that if any element of r is accessed, all of
  # them are executed together.
  r = nest.map_structure(tf.identity, r)

with ops.control_dependencies([ensure_lock_exists]):
  return nest.map_structure(tf.identity, r)

```

While `fn` is running in the critical section, no other functions which wish to use this critical section may run.

Often the use case is that two executions of the same graph, in parallel, wish to run `fn`; and we wish to ensure that only one of them executes at a time. This is especially important if `fn` modifies one or more variables at a time.

It is also useful if two separate functions must share a resource, but we wish to ensure the usage is exclusive.

Arguments:

mutex: The mutex resource to lock.

Returns A tensor that keeps a shared pointer to a lock on the mutex; when the Tensor is destroyed, the use count on the shared pointer is decreased by 1. When it reaches 0, the lock is released.

func Pack ¶ added in v1.1.0

func Pack(scope *Scope, values []tf.Output, optional ...PackAttr) (output tf.Output)

Packs a list of `N` rank-`R` tensors into one rank-`(R+1)` tensor.

Packs the `N` tensors in `values` into a tensor with rank one higher than each tensor in `values`, by packing them along the `axis` dimension. Given a list of tensors of shape `(A, B, C)`;

if `axis == 0` then the `output` tensor will have the shape `(N, A, B, C)`. if `axis == 1` then the `output` tensor will have the shape `(A, N, B, C)`. Etc.

For example:

``` # 'x' is [1, 4] # 'y' is [2, 5] # 'z' is [3, 6] pack([x, y, z]) => [[1, 4], [2, 5], [3, 6]] # Pack along first dim. pack([x, y, z], axis=1) => [[1, 2, 3], [4, 5, 6]] ```

This is the opposite of `unpack`.

Arguments:

values: Must be of same shape and type.

Returns The packed tensor.

func Pad ¶ added in v1.1.0

func Pad(scope *Scope, input tf.Output, paddings tf.Output) (output tf.Output)

Pads a tensor with zeros.

This operation pads a `input` with zeros according to the `paddings` you specify. `paddings` is an integer tensor with shape `[Dn, 2]`, where n is the rank of `input`. For each dimension D of `input`, `paddings[D, 0]` indicates how many zeros to add before the contents of `input` in that dimension, and `paddings[D, 1]` indicates how many zeros to add after the contents of `input` in that dimension.

The padded size of each dimension D of the output is:

`paddings(D, 0) + input.dim_size(D) + paddings(D, 1)`

For example:

``` # 't' is [[1, 1], [2, 2]] # 'paddings' is [[1, 1], [2, 2]] # rank of 't' is 2 pad(t, paddings) ==> [[0, 0, 0, 0, 0, 0]

[0, 0, 1, 1, 0, 0]
[0, 0, 2, 2, 0, 0]
[0, 0, 0, 0, 0, 0]]

```

func PadV2 ¶ added in v1.3.0

func PadV2(scope *Scope, input tf.Output, paddings tf.Output, constant_values tf.Output) (output tf.Output)

Pads a tensor.

This operation pads `input` according to the `paddings` and `constant_values` you specify. `paddings` is an integer tensor with shape `[Dn, 2]`, where n is the rank of `input`. For each dimension D of `input`, `paddings[D, 0]` indicates how many padding values to add before the contents of `input` in that dimension, and `paddings[D, 1]` indicates how many padding values to add after the contents of `input` in that dimension. `constant_values` is a scalar tensor of the same type as `input` that indicates the value to use for padding `input`.

The padded size of each dimension D of the output is:

`paddings(D, 0) + input.dim_size(D) + paddings(D, 1)`

For example:

``` # 't' is [[1, 1], [2, 2]] # 'paddings' is [[1, 1], [2, 2]] # 'constant_values' is 0 # rank of 't' is 2 pad(t, paddings) ==> [[0, 0, 0, 0, 0, 0]

[0, 0, 1, 1, 0, 0]
[0, 0, 2, 2, 0, 0]
[0, 0, 0, 0, 0, 0]]

```

func PaddedBatchDataset ¶ added in v1.2.0

Creates a dataset that batches and pads `batch_size` elements from the input.

Arguments:

batch_size: A scalar representing the number of elements to accumulate in a

batch.

padded_shapes: A list of int64 tensors representing the desired padded shapes

of the corresponding output components. These shapes may be partially specified, using `-1` to indicate that a particular dimension should be padded to the maximum size of all batch elements.

padding_values: A list of scalars containing the padding value to use for

each of the outputs.

func PaddedBatchDatasetV2 ¶ added in v1.11.0

func PaddedBatchDatasetV2(scope *Scope, input_dataset tf.Output, batch_size tf.Output, padded_shapes []tf.Output, padding_values []tf.Output, drop_remainder tf.Output, output_shapes []tf.Shape, optional ...PaddedBatchDatasetV2Attr) (handle tf.Output)

Creates a dataset that batches and pads `batch_size` elements from the input.

Arguments:

batch_size: A scalar representing the number of elements to accumulate in a

batch.

padded_shapes: A list of int64 tensors representing the desired padded shapes

of the corresponding output components. These shapes may be partially specified, using `-1` to indicate that a particular dimension should be padded to the maximum size of all batch elements.

padding_values: A list of scalars containing the padding value to use for

each of the outputs.

drop_remainder: A scalar representing whether the last batch should be dropped in case its size

is smaller than desired.

func PaddingFIFOQueueV2 ¶ added in v1.1.0

func PaddingFIFOQueueV2(scope *Scope, component_types []tf.DataType, optional ...PaddingFIFOQueueV2Attr) (handle tf.Output)

A queue that produces elements in first-in first-out order.

Variable-size shapes are allowed by setting the corresponding shape dimensions to 0 in the shape attr. In this case DequeueMany will pad up to the maximum size of any given element in the minibatch. See below for details.

Arguments:

component_types: The type of each component in a value.

Returns The handle to the queue.

func ParallelConcat ¶ added in v1.1.0

func ParallelConcat(scope *Scope, values []tf.Output, shape tf.Shape) (output tf.Output)

Concatenates a list of `N` tensors along the first dimension.

The input tensors are all required to have size 1 in the first dimension.

For example:

``` # 'x' is [[1, 4]] # 'y' is [[2, 5]] # 'z' is [[3, 6]] parallel_concat([x, y, z]) => [[1, 4], [2, 5], [3, 6]] # Pack along first dim. ```

The difference between concat and parallel_concat is that concat requires all of the inputs be computed before the operation will begin but doesn't require that the input shapes be known during graph construction. Parallel concat will copy pieces of the input into the output as they become available, in some situations this can provide a performance benefit.

Arguments:

values: Tensors to be concatenated. All must have size 1 in the first dimension

and same shape.

shape: the final shape of the result; should be equal to the shapes of any input

but with the number of input values in the first dimension.

Returns The concatenated tensor.

func ParallelDynamicStitch ¶ added in v1.4.0

func ParallelDynamicStitch(scope *Scope, indices []tf.Output, data []tf.Output) (merged tf.Output)

Interleave the values from the `data` tensors into a single tensor.

Builds a merged tensor such that ¶

```python

merged[indices[m][i, ..., j], ...] = data[m][i, ..., j, ...]

```

For example, if each `indices[m]` is scalar or vector, we have

```python

# Scalar indices:
merged[indices[m], ...] = data[m][...]

# Vector indices:
merged[indices[m][i], ...] = data[m][i, ...]

```

Each `data[i].shape` must start with the corresponding `indices[i].shape`, and the rest of `data[i].shape` must be constant w.r.t. `i`. That is, we must have `data[i].shape = indices[i].shape + constant`. In terms of this `constant`, the output shape is

merged.shape = [max(indices)] + constant

Values may be merged in parallel, so if an index appears in both `indices[m][i]` and `indices[n][j]`, the result may be invalid. This differs from the normal DynamicStitch operator that defines the behavior in that case.

For example:

```python

indices[0] = 6
indices[1] = [4, 1]
indices[2] = [[5, 2], [0, 3]]
data[0] = [61, 62]
data[1] = [[41, 42], [11, 12]]
data[2] = [[[51, 52], [21, 22]], [[1, 2], [31, 32]]]
merged = [[1, 2], [11, 12], [21, 22], [31, 32], [41, 42],
          [51, 52], [61, 62]]

```

This method can be used to merge partitions created by `dynamic_partition` as illustrated on the following example:

```python

# Apply function (increments x_i) on elements for which a certain condition
# apply (x_i != -1 in this example).
x=tf.constant([0.1, -1., 5.2, 4.3, -1., 7.4])
condition_mask=tf.not_equal(x,tf.constant(-1.))
partitioned_data = tf.dynamic_partition(
    x, tf.cast(condition_mask, tf.int32) , 2)
partitioned_data[1] = partitioned_data[1] + 1.0
condition_indices = tf.dynamic_partition(
    tf.range(tf.shape(x)[0]), tf.cast(condition_mask, tf.int32) , 2)
x = tf.dynamic_stitch(condition_indices, partitioned_data)
# Here x=[1.1, -1., 6.2, 5.3, -1, 8.4], the -1. values remain
# unchanged.

```

for each batch.

func ParseExample ¶ added in v1.1.0

func ParseExample(scope *Scope, serialized tf.Output, names tf.Output, sparse_keys []tf.Output, dense_keys []tf.Output, dense_defaults []tf.Output, sparse_types []tf.DataType, dense_shapes []tf.Shape) (sparse_indices []tf.Output, sparse_values []tf.Output, sparse_shapes []tf.Output, dense_values []tf.Output)

Transforms a vector of brain.Example protos (as strings) into typed tensors.

Arguments:

serialized: A vector containing a batch of binary serialized Example protos.
names: A vector containing the names of the serialized protos.

May contain, for example, table key (descriptive) names for the corresponding serialized protos. These are purely useful for debugging purposes, and the presence of values here has no effect on the output. May also be an empty vector if no names are available. If non-empty, this vector must be the same length as "serialized".

sparse_keys: A list of Nsparse string Tensors (scalars).

The keys expected in the Examples' features associated with sparse values.

dense_keys: A list of Ndense string Tensors (scalars).

The keys expected in the Examples' features associated with dense values.

dense_defaults: A list of Ndense Tensors (some may be empty).

dense_defaults[j] provides default values when the example's feature_map lacks dense_key[j]. If an empty Tensor is provided for dense_defaults[j], then the Feature dense_keys[j] is required. The input type is inferred from dense_defaults[j], even when it's empty. If dense_defaults[j] is not empty, and dense_shapes[j] is fully defined, then the shape of dense_defaults[j] must match that of dense_shapes[j]. If dense_shapes[j] has an undefined major dimension (variable strides dense feature), dense_defaults[j] must contain a single element: the padding element.

given in dense_keys. The number of elements in the Feature corresponding to dense_key[j] must always equal dense_shapes[j].NumEntries(). If dense_shapes[j] == (D0, D1, ..., DN) then the shape of output Tensor dense_values[j] will be (|serialized|, D0, D1, ..., DN): The dense outputs are just the inputs row-stacked by batch. This works for dense_shapes[j] = (-1, D1, ..., DN). In this case the shape of the output Tensor dense_values[j] will be (|serialized|, M, D1, .., DN), where M is the maximum number of blocks of elements of length D1 * .... * DN, across all minibatch entries in the input. Any minibatch entry with less than M blocks of elements of length D1 * ... * DN will be padded with the corresponding default_value scalar element along the second dimension.

context_dense_defaults: A list of Ncontext_dense Tensors (some may be empty).

context_dense_defaults[j] provides default values when the SequenceExample's context map lacks context_dense_key[j].

Arguments:

the length of `dense_keys`. dense_defaults[j] provides default values when the example's feature_map lacks dense_key[j]. If an empty Tensor is provided for dense_defaults[j], then the Feature dense_keys[j] is required. The input type is inferred from dense_defaults[j], even when it's empty. If dense_defaults[j] is not empty, and dense_shapes[j] is fully defined, then the shape of dense_defaults[j] must match that of dense_shapes[j]. If dense_shapes[j] has an undefined major dimension (variable strides dense feature), dense_defaults[j] must contain a single element: the padding element.

num_sparse: The number of sparse features to be parsed from the example. This

must match the lengths of `sparse_keys` and `sparse_types`.

If an empty Tensor is provided for context_dense_defaults[j], then the Feature context_dense_keys[j] is required. The input type is inferred from context_dense_defaults[j], even when it's empty. If context_dense_defaults[j] is not empty, its shape must match context_dense_shapes[j].

debug_name: A scalar containing the name of the serialized proto.

May contain, for example, table key (descriptive) name for the corresponding serialized proto. This is purely useful for debugging purposes, and the presence of values here has no effect on the output. May also be an empty scalar if no name is available.

func Placeholder(scope *Scope, dtype tf.DataType, optional ...PlaceholderAttr) (output tf.Output)

A placeholder op for a value that will be fed into the computation.

N.B. This operation will fail with an error if it is executed. It is intended as a way to represent a value that will always be fed, and to provide attrs that enable the fed value to be checked at runtime.

func PlaceholderV2 ¶ added in v1.1.0

func PlaceholderV2(scope *Scope, dtype tf.DataType, shape tf.Shape) (output tf.Output)

A placeholder op for a value that will be fed into the computation.

DEPRECATED at GraphDef version 23: Placeholder now behaves the same as PlaceholderV2.

N.B. This operation will fail with an error if it is executed. It is intended as a way to represent a value that will always be fed, and to provide attrs that enable the fed value to be checked at runtime.

Arguments:

dtype: The type of elements in the tensor.
shape: The shape of the tensor. The shape can be any partially-specified

shape. To be unconstrained, pass in a shape with unknown rank.

func PopulationCount ¶ added in v1.4.0

func PopulationCount(scope *Scope, x tf.Output) (y tf.Output)

Computes element-wise population count (a.k.a. popcount, bitsum, bitcount).

For each entry in `x`, calculates the number of `1` (on) bits in the binary representation of that entry.

**NOTE**: It is more efficient to first `tf.bitcast` your tensors into `int32` or `int64` and perform the bitcount on the result, than to feed in 8- or 16-bit inputs and then aggregate the resulting counts.

func Pow ¶ added in v1.1.0

func Pow(scope *Scope, x tf.Output, y tf.Output) (z tf.Output)

An identity op that triggers an error if a gradient is requested.

When executed in a graph, this op outputs its input tensor as-is.

When building ops to compute gradients, the TensorFlow gradient system will return an error when trying to lookup the gradient of this op, because no gradient must ever be registered for this function.

Note that the PriorityQueue requires the first component of any element to be a scalar int64, in addition to the other elements declared by component_types. Therefore calls to Enqueue and EnqueueMany (resp. Dequeue and DequeueMany) on a PriorityQueue will all require (resp. output) one extra entry in their input (resp. output) lists.

Arguments:

shapes: The shape of each component in a value. The length of this attr must

be either 0 or the same as the length of component_types. If the length of this attr is 0, the shapes of queue elements are not constrained, and only one element may be dequeued at a time.

Arguments:

input: A tensor of shape `[..., M, N]` whose inner-most 2 dimensions

form matrices of size `[M, N]`. Let `P` be the minimum of `M` and `N`.

Returns Orthonormal basis for range of `a`. If `full_matrices` is `False` then shape is `[..., M, P]`; if `full_matrices` is `True` then shape is `[..., M, M]`.Triangular factor. If `full_matrices` is `False` then shape is `[..., P, N]`. If `full_matrices` is `True` then shape is `[..., M, N]`.

func QuantizeAndDequantize ¶ added in v1.1.0

Use QuantizeAndDequantizeV2 instead.

DEPRECATED at GraphDef version 22: Replaced by QuantizeAndDequantizeV2

func QuantizeAndDequantizeV2 ¶ added in v1.1.0

func QuantizeAndDequantizeV2(scope *Scope, input tf.Output, input_min tf.Output, input_max tf.Output, optional ...QuantizeAndDequantizeV2Attr) (output tf.Output)

Quantizes then dequantizes a tensor.

This op simulates the precision loss from the quantized forward pass by:

Quantizing the tensor to fixed point numbers, which should match the target quantization method when it is used in inference.
Dequantizing it back to floating point numbers for the following ops, most likely matmul.

There are different ways to quantize. This version uses only scaling, so 0.0 maps to 0.

From the specified 'num_bits' in the quantized output type, it determines minimum and maximum representable quantized values.

e.g.

* [-128, 127] for signed, num_bits = 8, or * [0, 255] for unsigned, num_bits = 8.

If range_given == False, the initial input_min, input_max will be determined automatically as the minimum and maximum values in the input tensor, otherwise the specified values of input_min, input_max are used.

Note: If the input_min, input_max are specified, they do not need to equal the actual minimum and maximum values in the tensor. e.g. in some cases it may be beneficial to specify these values such that the low probability extremes of the input distribution are clipped.

This op determines the maximum scale_factor that would map the initial [input_min, input_max] range to a range that lies within the representable quantized range.

It determines the scale from one of input_min and input_max, then updates the other one to maximize the respresentable range.

e.g.

if the output is signed, num_bits = 8, [input_min, input_max] = [-10.0, 5.0]: it would use a scale_factor of -128 / -10.0 = 12.8 In this case, it would update input_max to be 127 / 12.8 = 9.921875
if the output is signed, num_bits = 8, [input_min, input_max] = [-10.0, 10.0]: it would use a scale_factor of 127 / 10.0 = 12.7 In this case, it would update input_min to be 128.0 / 12.7 = -10.07874
if the output is unsigned, input_min is forced to be 0, and only the specified input_max is used.

After determining the scale_factor and updating the input range, it applies the following to each value in the 'input' tensor.

output = round(clamp(value, input_min, input_max) * scale_factor) / scale_factor.

The above round function rounds the value based on the given round_mode.

Arguments:

input: Tensor to quantize and then dequantize.
input_min: If `range_given == True`, this specifies the minimum input value that needs to

be represented, otherwise it is determined from the min value of the `input` tensor.

input_max: If `range_given == True`, this specifies the maximum input value that needs to

be represented, otherwise it is determined from the max value of the `input` tensor.

func QuantizeAndDequantizeV3 ¶ added in v1.3.0

func QuantizeAndDequantizeV3(scope *Scope, input tf.Output, input_min tf.Output, input_max tf.Output, num_bits tf.Output, optional ...QuantizeAndDequantizeV3Attr) (output tf.Output)

Quantizes then dequantizes a tensor.

This is almost identical to QuantizeAndDequantizeV2, except that num_bits is a tensor, so its value can change during training.

func QuantizeDownAndShrinkRange ¶ added in v1.1.0

func QuantizeDownAndShrinkRange(scope *Scope, input tf.Output, input_min tf.Output, input_max tf.Output, out_type tf.DataType) (output tf.Output, output_min tf.Output, output_max tf.Output)

Convert the quantized 'input' tensor into a lower-precision 'output', using the

actual distribution of the values to maximize the usage of the lower bit depth and adjusting the output min and max ranges accordingly.

[input_min, input_max] are scalar floats that specify the range for the float interpretation of the 'input' data. For example, if input_min is -1.0f and input_max is 1.0f, and we are dealing with quint16 quantized data, then a 0 value in the 16-bit data should be interpreted as -1.0f, and a 65535 means 1.0f.

This operator tries to squeeze as much precision as possible into an output with a lower bit depth by calculating the actual min and max values found in the data. For example, maybe that quint16 input has no values lower than 16,384 and none higher than 49,152. That means only half the range is actually needed, all the float interpretations are between -0.5f and 0.5f, so if we want to compress the data into a quint8 output, we can use that range rather than the theoretical -1.0f to 1.0f that is suggested by the input min and max.

In practice, this is most useful for taking output from operations like QuantizedMatMul that can produce higher bit-depth outputs than their inputs and may have large potential output ranges, but in practice have a distribution of input values that only uses a small fraction of the possible range. By feeding that output into this operator, we can reduce it from 32 bits down to 8 with minimal loss of accuracy.

Arguments:

input_min: The float value that the minimum quantized input value represents.
input_max: The float value that the maximum quantized input value represents.
out_type: The type of the output. Should be a lower bit depth than Tinput.

Returns The float value that the minimum quantized output value represents.The float value that the maximum quantized output value represents.

func QuantizeV2 ¶ added in v1.1.0

func QuantizeV2(scope *Scope, input tf.Output, min_range tf.Output, max_range tf.Output, T tf.DataType, optional ...QuantizeV2Attr) (output tf.Output, output_min tf.Output, output_max tf.Output)

Quantize the 'input' tensor of type float to 'output' tensor of type 'T'.

[min_range, max_range] are scalar floats that specify the range for the 'input' data. The 'mode' attribute controls exactly which calculations are used to convert the float values to their quantized equivalents. The 'round_mode' attribute controls which rounding tie-breaking algorithm is used when rounding float values to their quantized equivalents.

In 'MIN_COMBINED' mode, each value of the tensor will undergo the following:

``` out[i] = (in[i] - min_range) * range(T) / (max_range - min_range) if T == qint8: out[i] -= (range(T) + 1) / 2.0 ```

here `range(T) = numeric_limits<T>::max() - numeric_limits<T>::min()`

*MIN_COMBINED Mode Example*

Assume the input is type float and has a possible range of [0.0, 6.0] and the output type is quint8 ([0, 255]). The min_range and max_range values should be specified as 0.0 and 6.0. Quantizing from float to quint8 will multiply each value of the input by 255/6 and cast to quint8.

If the output type was qint8 ([-128, 127]), the operation will additionally subtract each value by 128 prior to casting, so that the range of values aligns with the range of qint8.

If the mode is 'MIN_FIRST', then this approach is used:

``` num_discrete_values = 1 << (# of bits in T) range_adjust = num_discrete_values / (num_discrete_values - 1) range = (range_max - range_min) * range_adjust range_scale = num_discrete_values / range quantized = round(input * range_scale) - round(range_min * range_scale) +

numeric_limits<T>::min()

quantized = max(quantized, numeric_limits<T>::min()) quantized = min(quantized, numeric_limits<T>::max()) ```

The biggest difference between this and MIN_COMBINED is that the minimum range is rounded first, before it's subtracted from the rounded value. With MIN_COMBINED, a small bias is introduced where repeated iterations of quantizing and dequantizing will introduce a larger and larger error.

*SCALED mode Example*

`SCALED` mode matches the quantization approach used in `QuantizeAndDequantize{V2|V3}`.

If the mode is `SCALED`, we do not use the full range of the output type, choosing to elide the lowest possible value for symmetry (e.g., output range is -127 to 127, not -128 to 127 for signed 8 bit quantization), so that 0.0 maps to 0.

We first find the range of values in our tensor. The range we use is always centered on 0, so we find m such that

```c++

m = max(abs(input_min), abs(input_max))

```

Our input tensor range is then `[-m, m]`.

Next, we choose our fixed-point quantization buckets, `[min_fixed, max_fixed]`. If T is signed, this is

```

num_bits = sizeof(T) * 8
[min_fixed, max_fixed] =
    [-(1 << (num_bits - 1) - 1), (1 << (num_bits - 1)) - 1]

```

Otherwise, if T is unsigned, the fixed-point range is ¶

```

[min_fixed, max_fixed] = [0, (1 << num_bits) - 1]

```

From this we compute our scaling factor, s:

```c++

s = (max_fixed - min_fixed) / (2 * m)

```

Now we can quantize the elements of our tensor:

```c++ result = round(input * s) ```

One thing to watch out for is that the operator may choose to adjust the requested minimum and maximum values slightly during the quantization process, so you should always use the output ports as the range for further calculations. For example, if the requested minimum and maximum values are close to equal, they will be separated by a small epsilon value to prevent ill-formed quantized buffers from being created. Otherwise, you can end up with buffers where all the quantized values map to the same float value, which causes problems for operations that have to perform further calculations on them.

Arguments:

min_range: The minimum scalar value possibly produced for the input.
max_range: The maximum scalar value possibly produced for the input.

Returns The quantized data produced from the float input.The actual minimum scalar value used for the output.The actual maximum scalar value used for the output.

Given `tensor`, this operation returns a tensor that has the same values as `tensor` with shape `shape`.

If one component of `shape` is the special value -1, the size of that dimension is computed so that the total size remains constant. In particular, a `shape` of `[-1]` flattens into 1-D. At most one component of `shape` can be -1.

If `shape` is 1-D or higher, then the operation returns a tensor with shape `shape` filled with the values of `tensor`. In this case, the number of elements implied by `shape` must be the same as the number of elements in `tensor`.

The values of `value` are assigned to the positions in the variable `ref` that are selected by the slice parameters. The slice parameters `begin, `end`, `strides`, etc. work exactly as in `StridedSlice`.

NOTE this op currently does not support broadcasting and so `value`'s shape must be exactly the shape produced by the slice of `ref`.

Returns the created operation.

func Restore ¶ added in v1.1.0

func Restore(scope *Scope, file_pattern tf.Output, tensor_name tf.Output, dt tf.DataType, optional ...RestoreAttr) (tensor tf.Output)

Restores a tensor from checkpoint files.

Reads a tensor stored in one or several files. If there are several files (for instance because a tensor was saved as slices), `file_pattern` may contain wildcard symbols (`*` and `?`) in the filename portion only, not in the directory portion.

If a `file_pattern` matches several files, `preferred_shard` can be used to hint in which file the requested tensor is likely to be found. This op will first open the file at index `preferred_shard` in the list of matching files and try to restore tensors from that file. Only if some tensors or tensor slices are not found in that first file, then the Op opens all the files. Setting `preferred_shard` to match the value passed as the `shard` input of a matching `Save` Op may speed up Restore. This attribute only affects performance, not correctness. The default value -1 means files are processed in order.

func RestoreSlice ¶ added in v1.1.0

func RestoreSlice(scope *Scope, file_pattern tf.Output, tensor_name tf.Output, shape_and_slice tf.Output, dt tf.DataType, optional ...RestoreSliceAttr) (tensor tf.Output)

Restores a tensor from checkpoint files.

This is like `Restore` except that restored tensor can be listed as filling only a slice of a larger tensor. `shape_and_slice` specifies the shape of the larger tensor and the slice that the restored tensor covers.

The `shape_and_slice` input has the same format as the elements of the `shapes_and_slices` input of the `SaveSlices` op.

Arguments:

file_pattern: Must have a single element. The pattern of the files from

which we read the tensor.

tensor_name: Must have a single element. The name of the tensor to be

restored.

shape_and_slice: Scalar. The shapes and slice specifications to use when

restoring a tensors.

dt: The type of the tensor to be restored.

Returns The restored tensor.

func RestoreV2 ¶ added in v1.1.0

func RestoreV2(scope *Scope, prefix tf.Output, tensor_names tf.Output, shape_and_slices tf.Output, dtypes []tf.DataType) (tensors []tf.Output)

Restores tensors from a V2 checkpoint.

For backward compatibility with the V1 format, this Op currently allows restoring from a V1 checkpoint as well:

This Op first attempts to find the V2 index file pointed to by "prefix", and if found proceed to read it as a V2 checkpoint;
Otherwise the V1 read path is invoked.

Relying on this behavior is not recommended, as the ability to fall back to read V1 might be deprecated and eventually removed.

By default, restores the named tensors in full. If the caller wishes to restore specific slices of stored tensors, "shape_and_slices" should be non-empty strings and correspondingly well-formed.

Callers must ensure all the named tensors are indeed stored in the checkpoint.

Arguments:

prefix: Must have a single element.  The prefix of a V2 checkpoint.
tensor_names: shape {N}.  The names of the tensors to be restored.
shape_and_slices: shape {N}.  The slice specs of the tensors to be restored.

Empty strings indicate that they are non-partitioned tensors.

dtypes: shape {N}.  The list of expected dtype for the tensors.  Must match

those stored in the checkpoint.

Returns shape {N}. The restored tensors, whose shapes are read from the checkpoint directly.

func Reverse(scope *Scope, tensor tf.Output, dims tf.Output) (output tf.Output)

Reverses specific dimensions of a tensor.

Given a `tensor`, and a `bool` tensor `dims` representing the dimensions of `tensor`, this operation reverses each dimension i of `tensor` where `dims[i]` is `True`.

`tensor` can have up to 8 dimensions. The number of dimensions of `tensor` must equal the number of elements in `dims`. In other words:

`rank(tensor) = size(dims)`

For example:

``` # tensor 't' is [[[[ 0, 1, 2, 3], # [ 4, 5, 6, 7], # [ 8, 9, 10, 11]], # [[12, 13, 14, 15], # [16, 17, 18, 19], # [20, 21, 22, 23]]]] # tensor 't' shape is [1, 2, 3, 4]

# 'dims' is [False, False, False, True] reverse(t, dims) ==> [[[[ 3, 2, 1, 0],

 [ 7,  6,  5,  4],
 [ 11, 10, 9, 8]],
[[15, 14, 13, 12],
 [19, 18, 17, 16],
 [23, 22, 21, 20]]]]

# 'dims' is [False, True, False, False] reverse(t, dims) ==> [[[[12, 13, 14, 15],

 [16, 17, 18, 19],
 [20, 21, 22, 23]
[[ 0,  1,  2,  3],
 [ 4,  5,  6,  7],
 [ 8,  9, 10, 11]]]]

# 'dims' is [False, False, True, False] reverse(t, dims) ==> [[[[8, 9, 10, 11],

 [4, 5, 6, 7],
 [0, 1, 2, 3]]
[[20, 21, 22, 23],
 [16, 17, 18, 19],
 [12, 13, 14, 15]]]]

```

Arguments:

tensor: Up to 8-D.
dims: 1-D. The dimensions to reverse.

func ReverseSequence ¶ added in v1.1.0

func ReverseSequence(scope *Scope, input tf.Output, seq_lengths tf.Output, seq_dim int64, optional ...ReverseSequenceAttr) (output tf.Output)

Reverses variable length slices.

This op first slices `input` along the dimension `batch_dim`, and for each slice `i`, reverses the first `seq_lengths[i]` elements along the dimension `seq_dim`.

The elements of `seq_lengths` must obey `seq_lengths[i] <= input.dims[seq_dim]`, and `seq_lengths` must be a vector of length `input.dims[batch_dim]`.

The output slice `i` along dimension `batch_dim` is then given by input slice `i`, with the first `seq_lengths[i]` slices along dimension `seq_dim` reversed.

For example:

``` # Given this: batch_dim = 0 seq_dim = 1 input.dims = (4, 8, ...) seq_lengths = [7, 2, 3, 5]

# then slices of input are reversed on seq_dim, but only up to seq_lengths: output[0, 0:7, :, ...] = input[0, 7:0:-1, :, ...] output[1, 0:2, :, ...] = input[1, 2:0:-1, :, ...] output[2, 0:3, :, ...] = input[2, 3:0:-1, :, ...] output[3, 0:5, :, ...] = input[3, 5:0:-1, :, ...]

# while entries past seq_lens are copied through: output[0, 7:, :, ...] = input[0, 7:, :, ...] output[1, 2:, :, ...] = input[1, 2:, :, ...] output[2, 3:, :, ...] = input[2, 3:, :, ...] output[3, 2:, :, ...] = input[3, 2:, :, ...] ```

In contrast, if:

``` # Given this: batch_dim = 2 seq_dim = 0 input.dims = (8, ?, 4, ...) seq_lengths = [7, 2, 3, 5]

# then slices of input are reversed on seq_dim, but only up to seq_lengths: output[0:7, :, 0, :, ...] = input[7:0:-1, :, 0, :, ...] output[0:2, :, 1, :, ...] = input[2:0:-1, :, 1, :, ...] output[0:3, :, 2, :, ...] = input[3:0:-1, :, 2, :, ...] output[0:5, :, 3, :, ...] = input[5:0:-1, :, 3, :, ...]

# while entries past seq_lens are copied through: output[7:, :, 0, :, ...] = input[7:, :, 0, :, ...] output[2:, :, 1, :, ...] = input[2:, :, 1, :, ...] output[3:, :, 2, :, ...] = input[3:, :, 2, :, ...] output[2:, :, 3, :, ...] = input[2:, :, 3, :, ...] ```

Arguments:

input: The input to reverse.
seq_lengths: 1-D with length `input.dims(batch_dim)` and

`max(seq_lengths) <= input.dims(seq_dim)`

seq_dim: The dimension which is partially reversed.

Returns The partially reversed input. It has the same shape as `input`.

func ReverseV2 ¶ added in v1.1.0

func ReverseV2(scope *Scope, tensor tf.Output, axis tf.Output) (output tf.Output)

Given a `tensor`, and a `int32` tensor `axis` representing the set of dimensions of `tensor` to reverse. This operation reverses each dimension `i` for which there exists `j` s.t. `axis[j] == i`.

`tensor` can have up to 8 dimensions. The number of dimensions specified in `axis` may be 0 or more entries. If an index is specified more than once, a InvalidArgument error is raised.

For example:

``` # tensor 't' is [[[[ 0, 1, 2, 3], # [ 4, 5, 6, 7], # [ 8, 9, 10, 11]], # [[12, 13, 14, 15], # [16, 17, 18, 19], # [20, 21, 22, 23]]]] # tensor 't' shape is [1, 2, 3, 4]

# 'dims' is [3] or 'dims' is [-1] reverse(t, dims) ==> [[[[ 3, 2, 1, 0],

 [ 7,  6,  5,  4],
 [ 11, 10, 9, 8]],
[[15, 14, 13, 12],
 [19, 18, 17, 16],
 [23, 22, 21, 20]]]]

 [0, 1, 2, 3]]
[[20, 21, 22, 23],
 [16, 17, 18, 19],
 [12, 13, 14, 15]]]]

```

Arguments:

tensor: Up to 8-D.
axis: 1-D. The indices of the dimensions to reverse. Must be in the range

`[-rank(tensor), rank(tensor))`.

func RightShift ¶ added in v1.5.0

func RightShift(scope *Scope, x tf.Output, y tf.Output) (z tf.Output)

Elementwise computes the bitwise right-shift of `x` and `y`.

Performs a logical shift for unsigned integer types, and an arithmetic shift for signed integer types.

If `y` is negative, or greater than or equal to than the width of `x` in bits the result is implementation defined.

func Rint ¶ added in v1.1.0

func Rint(scope *Scope, x tf.Output) (y tf.Output)

Returns element-wise integer closest to x.

If the result is midway between two representable values, the even representable is chosen. For example:

``` rint(-1.5) ==> -2.0 rint(0.5000001) ==> 1.0 rint([-1.7, -1.5, -0.2, 0.2, 1.5, 1.7, 2.0]) ==> [-2., -2., -0., 0., 2., 2., 2.] ```

func RngSkip ¶ added in v1.14.0

func RngSkip(scope *Scope, resource tf.Output, algorithm tf.Output, delta tf.Output) (o *tf.Operation)

Advance the counter of a counter-based RNG.

The state of the RNG after `rng_skip(n)` will be the same as that after `stateful_uniform([n])` (or any other distribution). The actual increment added to the counter is an unspecified implementation detail.

Arguments:

resource: The handle of the resource variable that stores the state of the RNG.
algorithm: The RNG algorithm.
delta: The amount of advancement.

Returns the created operation.

func Roll ¶ added in v1.9.0

func Roll(scope *Scope, input tf.Output, shift tf.Output, axis tf.Output) (output tf.Output)

Rolls the elements of a tensor along an axis.

The elements are shifted positively (towards larger indices) by the offset of `shift` along the dimension of `axis`. Negative `shift` values will shift elements in the opposite direction. Elements that roll passed the last position will wrap around to the first and vice versa. Multiple shifts along multiple axes may be specified.

For example:

``` # 't' is [0, 1, 2, 3, 4] roll(t, shift=2, axis=0) ==> [3, 4, 0, 1, 2]

# shifting along multiple dimensions # 't' is [[0, 1, 2, 3, 4], [5, 6, 7, 8, 9]] roll(t, shift=[1, -2], axis=[0, 1]) ==> [[7, 8, 9, 5, 6], [2, 3, 4, 0, 1]]

# shifting along the same axis multiple times # 't' is [[0, 1, 2, 3, 4], [5, 6, 7, 8, 9]] roll(t, shift=[2, -3], axis=[1, 1]) ==> [[1, 2, 3, 4, 0], [6, 7, 8, 9, 5]] ```

Arguments:

shift: Dimension must be 0-D or 1-D. `shift[i]` specifies the number of places by which

elements are shifted positively (towards larger indices) along the dimension specified by `axis[i]`. Negative shifts will roll the elements in the opposite direction.

axis: Dimension must be 0-D or 1-D. `axis[i]` specifies the dimension that the shift

`shift[i]` should occur. If the same axis is referenced more than once, the total shift for that axis will be the sum of all the shifts that belong to that axis.

Returns Has the same shape and size as the input. The elements are shifted positively (towards larger indices) by the offsets of `shift` along the dimensions of `axis`.

func Round ¶ added in v1.1.0

func Round(scope *Scope, x tf.Output) (y tf.Output)

Rounds the values of a tensor to the nearest integer, element-wise.

Rounds half to even. Also known as bankers rounding. If you want to round according to the current system rounding mode use std::cint.

func Rpc ¶ added in v1.9.0

func Rpc(scope *Scope, address tf.Output, method tf.Output, request tf.Output, optional ...RpcAttr) (response tf.Output)

Perform batches of RPC requests.

This op asynchronously performs either a single RPC request, or a batch of requests. RPC requests are defined by three main parameters:

`address` (the host+port or BNS address of the request)
`method` (the RPC method name for the request)
`request` (the serialized proto string, or vector of strings, of the RPC request argument).

For example, if you have an RPC service running on port localhost:2345, and its interface is configured with the following proto declaration:

```

service MyService {
  rpc MyMethod(MyRequestProto) returns (MyResponseProto) {
  }
};

```

then call this op with arguments:

``` address = "localhost:2345" method = "MyService/MyMethod" ```

The `request` tensor is a string tensor representing serialized `MyRequestProto` strings; and the output string tensor `response` will have the same shape and contain (upon successful completion) corresponding serialized `MyResponseProto` strings.

For example, to send a single, empty, `MyRequestProto`, call this op with `request = ""`. To send 5 **parallel** empty requests, call this op with `request = ["", "", "", "", ""]`.

More generally, one can create a batch of `MyRequestProto` serialized protos from regular batched tensors using the `encode_proto` op, and convert the response `MyResponseProto` serialized protos to batched tensors using the `decode_proto` op.

**NOTE** Working with serialized proto strings is faster than instantiating actual proto objects in memory, so no performance degradation is expected compared to writing custom kernels for this workflow.

If the connection fails or the remote worker returns an error status, the op reraises this exception locally.

See the `TryRpc` op if you prefer to handle RPC failures manually in the graph.

Arguments:

address: `0-D` or `1-D`.  The address (i.e. host_name:port) of the RPC server.

If this tensor has more than 1 element, then multiple parallel rpc requests are sent. This argument broadcasts with `method` and `request`.

method: `0-D` or `1-D`.  The method address on the RPC server.

If this tensor has more than 1 element, then multiple parallel rpc requests are sent. This argument broadcasts with `address` and `request`.

request: `0-D` or `1-D`.  Serialized proto strings: the rpc request argument.

If this tensor has more than 1 element, then multiple parallel rpc requests are sent. This argument broadcasts with `address` and `method`.

Returns Same shape as `request`. Serialized proto strings: the rpc responses.

func Rsqrt ¶ added in v1.1.0

func Rsqrt(scope *Scope, x tf.Output) (y tf.Output)

Computes reciprocal of square root of x element-wise.

I.e., \$y = 1 / \sqrt{x}\$.

func RsqrtGrad ¶ added in v1.1.0

func RsqrtGrad(scope *Scope, y tf.Output, dy tf.Output) (z tf.Output)

Computes the gradient for the rsqrt of `x` wrt its input.

Specifically, `grad = dy * -0.5 * y^3`, where `y = rsqrt(x)`, and `dy` is the corresponding input gradient.

func SampleDistortedBoundingBox ¶ added in v1.1.0

func SampleDistortedBoundingBox(scope *Scope, image_size tf.Output, bounding_boxes tf.Output, optional ...SampleDistortedBoundingBoxAttr) (begin tf.Output, size tf.Output, bboxes tf.Output)

Generate a single randomly distorted bounding box for an image.

Bounding box annotations are often supplied in addition to ground-truth labels in image recognition or object localization tasks. A common technique for training such a system is to randomly distort an image while preserving its content, i.e. *data augmentation*. This Op outputs a randomly distorted localization of an object, i.e. bounding box, given an `image_size`, `bounding_boxes` and a series of constraints.

The output of this Op is a single bounding box that may be used to crop the original image. The output is returned as 3 tensors: `begin`, `size` and `bboxes`. The first 2 tensors can be fed directly into `tf.slice` to crop the image. The latter may be supplied to `tf.image.draw_bounding_boxes` to visualize what the bounding box looks like.

Bounding boxes are supplied and returned as `[y_min, x_min, y_max, x_max]`. The bounding box coordinates are floats in `[0.0, 1.0]` relative to the width and height of the underlying image.

For example,

```python

# Generate a single distorted bounding box.
begin, size, bbox_for_draw = tf.image.sample_distorted_bounding_box(
    tf.shape(image),
    bounding_boxes=bounding_boxes)

# Draw the bounding box in an image summary.
image_with_box = tf.image.draw_bounding_boxes(tf.expand_dims(image, 0),
                                              bbox_for_draw)
tf.summary.image('images_with_box', image_with_box)

# Employ the bounding box to distort the image.
distorted_image = tf.slice(image, begin, size)

```

Note that if no bounding box information is available, setting `use_image_if_no_bounding_boxes = true` will assume there is a single implicit bounding box covering the whole image. If `use_image_if_no_bounding_boxes` is false and no bounding boxes are supplied, an error is raised.

Arguments:

image_size: 1-D, containing `[height, width, channels]`.
bounding_boxes: 3-D with shape `[batch, N, 4]` describing the N bounding boxes

associated with the image.

Returns 1-D, containing `[offset_height, offset_width, 0]`. Provide as input to `tf.slice`.1-D, containing `[target_height, target_width, -1]`. Provide as input to `tf.slice`.3-D with shape `[1, 1, 4]` containing the distorted bounding box. Provide as input to `tf.image.draw_bounding_boxes`.

func SampleDistortedBoundingBoxV2 ¶ added in v1.3.0

func SampleDistortedBoundingBoxV2(scope *Scope, image_size tf.Output, bounding_boxes tf.Output, min_object_covered tf.Output, optional ...SampleDistortedBoundingBoxV2Attr) (begin tf.Output, size tf.Output, bboxes tf.Output)

Generate a single randomly distorted bounding box for an image.

Bounding box annotations are often supplied in addition to ground-truth labels in image recognition or object localization tasks. A common technique for training such a system is to randomly distort an image while preserving its content, i.e. *data augmentation*. This Op outputs a randomly distorted localization of an object, i.e. bounding box, given an `image_size`, `bounding_boxes` and a series of constraints.

The output of this Op is a single bounding box that may be used to crop the original image. The output is returned as 3 tensors: `begin`, `size` and `bboxes`. The first 2 tensors can be fed directly into `tf.slice` to crop the image. The latter may be supplied to `tf.image.draw_bounding_boxes` to visualize what the bounding box looks like.

Bounding boxes are supplied and returned as `[y_min, x_min, y_max, x_max]`. The bounding box coordinates are floats in `[0.0, 1.0]` relative to the width and height of the underlying image.

For example,

```python

# Generate a single distorted bounding box.
begin, size, bbox_for_draw = tf.image.sample_distorted_bounding_box(
    tf.shape(image),
    bounding_boxes=bounding_boxes)

# Draw the bounding box in an image summary.
image_with_box = tf.image.draw_bounding_boxes(tf.expand_dims(image, 0),
                                              bbox_for_draw)
tf.summary.image('images_with_box', image_with_box)

# Employ the bounding box to distort the image.
distorted_image = tf.slice(image, begin, size)

```

Note that if no bounding box information is available, setting `use_image_if_no_bounding_boxes = true` will assume there is a single implicit bounding box covering the whole image. If `use_image_if_no_bounding_boxes` is false and no bounding boxes are supplied, an error is raised.

Arguments:

image_size: 1-D, containing `[height, width, channels]`.
bounding_boxes: 3-D with shape `[batch, N, 4]` describing the N bounding boxes

associated with the image.

min_object_covered: The cropped area of the image must contain at least this

fraction of any bounding box supplied. The value of this parameter should be non-negative. In the case of 0, the cropped area does not need to overlap any of the bounding boxes supplied.

Returns 1-D, containing `[offset_height, offset_width, 0]`. Provide as input to `tf.slice`.1-D, containing `[target_height, target_width, -1]`. Provide as input to `tf.slice`.3-D with shape `[1, 1, 4]` containing the distorted bounding box. Provide as input to `tf.image.draw_bounding_boxes`.

func SamplingDataset ¶ added in v1.12.1

func SamplingDataset(scope *Scope, input_dataset tf.Output, rate tf.Output, seed tf.Output, seed2 tf.Output, output_types []tf.DataType, output_shapes []tf.Shape) (handle tf.Output)

Creates a dataset that contains `rate` elements from the `input_dataset`.

Arguments:

rate: A scalar representing the sample rate of elements from the `input_dataset`

that should be taken.

seed: A scalar representing seed of random number generator.
seed2: A scalar representing seed2 of random number generator.

func Save ¶ added in v1.1.0

func Save(scope *Scope, filename tf.Output, tensor_names tf.Output, data []tf.Output) (o *tf.Operation)

Saves the input tensors to disk.

The size of `tensor_names` must match the number of tensors in `data`. `data[i]` is written to `filename` with name `tensor_names[i]`.

func SaveSlices ¶ added in v1.1.0

func SaveSlices(scope *Scope, filename tf.Output, tensor_names tf.Output, shapes_and_slices tf.Output, data []tf.Output) (o *tf.Operation)

Saves input tensors slices to disk.

This is like `Save` except that tensors can be listed in the saved file as being a slice of a larger tensor. `shapes_and_slices` specifies the shape of the larger tensor and the slice that this tensor covers. `shapes_and_slices` must have as many elements as `tensor_names`.

Elements of the `shapes_and_slices` input must either be:

The empty string, in which case the corresponding tensor is saved normally.
A string of the form `dim0 dim1 ... dimN-1 slice-spec` where the `dimI` are the dimensions of the larger tensor and `slice-spec` specifies what part is covered by the tensor to save.

`slice-spec` itself is a `:`-separated list: `slice0:slice1:...:sliceN-1` where each `sliceI` is either:

The string `-` meaning that the slice covers all indices of this dimension
`start,length` where `start` and `length` are integers. In that case the slice covers `length` indices starting at `start`.

func SaveV2 ¶ added in v1.1.0

func SaveV2(scope *Scope, prefix tf.Output, tensor_names tf.Output, shape_and_slices tf.Output, tensors []tf.Output) (o *tf.Operation)

Saves tensors in V2 checkpoint format.

By default, saves the named tensors in full. If the caller wishes to save specific slices of full tensors, "shape_and_slices" should be non-empty strings and correspondingly well-formed.

Arguments:

prefix: Must have a single element. The prefix of the V2 checkpoint to which we

write the tensors.

tensor_names: shape {N}. The names of the tensors to be saved.
shape_and_slices: shape {N}.  The slice specs of the tensors to be saved.

Empty strings indicate that they are non-partitioned tensors.

tensors: `N` tensors to save.

Returns the created operation.

func ScalarSummary ¶ added in v1.1.0

func ScalarSummary(scope *Scope, tags tf.Output, values tf.Output) (summary tf.Output)

Outputs a `Summary` protocol buffer with scalar values.

The input `tags` and `values` must have the same shape. The generated summary has a summary value for each tag-value pair in `tags` and `values`.

Arguments:

tags: Tags for the summary.
values: Same shape as `tags.  Values for the summary.

Returns Scalar. Serialized `Summary` protocol buffer.

func ScatterNd ¶ added in v1.1.0

func ScatterNd(scope *Scope, indices tf.Output, updates tf.Output, shape tf.Output) (output tf.Output)

Scatter `updates` into a new tensor according to `indices`.

Creates a new tensor by applying sparse `updates` to individual values or slices within a tensor (initially zero for numeric, empty for string) of the given `shape` according to indices. This operator is the inverse of the `tf.gather_nd` operator which extracts values or slices from a given tensor.

This operation is similar to tensor_scatter_add, except that the tensor is zero-initialized. Calling `tf.scatter_nd(indices, values, shape)` is identical to `tensor_scatter_add(tf.zeros(shape, values.dtype), indices, values)`

If `indices` contains duplicates, then their updates are accumulated (summed).

**WARNING**: The order in which updates are applied is nondeterministic, so the output will be nondeterministic if `indices` contains duplicates -- because of some numerical approximation issues, numbers summed in different order may yield different results.

`indices` is an integer tensor containing indices into a new tensor of shape `shape`. The last dimension of `indices` can be at most the rank of `shape`:

indices.shape[-1] <= shape.rank

The last dimension of `indices` corresponds to indices into elements (if `indices.shape[-1] = shape.rank`) or slices (if `indices.shape[-1] < shape.rank`) along dimension `indices.shape[-1]` of `shape`. `updates` is a tensor with shape

indices.shape[:-1] + shape[indices.shape[-1]:]

The simplest form of scatter is to insert individual elements in a tensor by index. For example, say we want to insert 4 scattered elements in a rank-1 tensor with 8 elements.

In Python, this scatter operation would look like this:

```python

indices = tf.constant([[4], [3], [1], [7]])
updates = tf.constant([9, 10, 11, 12])
shape = tf.constant([8])
scatter = tf.scatter_nd(indices, updates, shape)
with tf.Session() as sess:
  print(sess.run(scatter))

```

The resulting tensor would look like this:

[0, 11, 0, 10, 9, 0, 0, 12]

We can also, insert entire slices of a higher rank tensor all at once. For example, if we wanted to insert two slices in the first dimension of a rank-3 tensor with two matrices of new values.

In Python, this scatter operation would look like this:

```python

indices = tf.constant([[0], [2]])
updates = tf.constant([[[5, 5, 5, 5], [6, 6, 6, 6],
                        [7, 7, 7, 7], [8, 8, 8, 8]],
                       [[5, 5, 5, 5], [6, 6, 6, 6],
                        [7, 7, 7, 7], [8, 8, 8, 8]]])
shape = tf.constant([4, 4, 4])
scatter = tf.scatter_nd(indices, updates, shape)
with tf.Session() as sess:
  print(sess.run(scatter))

```

The resulting tensor would look like this:

[[[5, 5, 5, 5], [6, 6, 6, 6], [7, 7, 7, 7], [8, 8, 8, 8]],
 [[0, 0, 0, 0], [0, 0, 0, 0], [0, 0, 0, 0], [0, 0, 0, 0]],
 [[5, 5, 5, 5], [6, 6, 6, 6], [7, 7, 7, 7], [8, 8, 8, 8]],
 [[0, 0, 0, 0], [0, 0, 0, 0], [0, 0, 0, 0], [0, 0, 0, 0]]]

Note that on CPU, if an out of bound index is found, an error is returned. On GPU, if an out of bound index is found, the index is ignored.

Arguments:

indices: Index tensor.
updates: Updates to scatter into output.
shape: 1-D. The shape of the resulting tensor.

Returns A new tensor with the given shape and updates applied according to the indices.

func ScatterNdNonAliasingAdd ¶ added in v1.3.0

func ScatterNdNonAliasingAdd(scope *Scope, input tf.Output, indices tf.Output, updates tf.Output) (output tf.Output)

Applies sparse addition to `input` using individual values or slices

from `updates` according to indices `indices`. The updates are non-aliasing: `input` is only modified in-place if no other operations will use it. Otherwise, a copy of `input` is made. This operation has a gradient with respect to both `input` and `updates`.

`input` is a `Tensor` with rank `P` and `indices` is a `Tensor` of rank `Q`.

`indices` must be integer tensor, containing indices into `input`. It must be shape \$[d_0, ..., d_{Q-2}, K]\$ where `0 < K <= P`.

The innermost dimension of `indices` (with length `K`) corresponds to indices into elements (if `K = P`) or `(P-K)`-dimensional slices (if `K < P`) along the `K`th dimension of `input`.

`updates` is `Tensor` of rank `Q-1+P-K` with shape:

$$[d_0, ..., d_{Q-2}, input.shape[K], ..., input.shape[P-1]].$$

For example, say we want to add 4 scattered elements to a rank-1 tensor to 8 elements. In Python, that addition would look like this:

input = tf.constant([1, 2, 3, 4, 5, 6, 7, 8])
indices = tf.constant([[4], [3], [1], [7]])
updates = tf.constant([9, 10, 11, 12])
output = tf.scatter_nd_non_aliasing_add(input, indices, updates)
with tf.Session() as sess:
  print(sess.run(output))

The resulting value `output` would look like this:

[1, 13, 3, 14, 14, 6, 7, 20]

See `tf.scatter_nd` for more details about how to make updates to slices.

Arguments:

input: A Tensor.
indices: A Tensor. Must be one of the following types: `int32`, `int64`.

A tensor of indices into `input`.

updates: A Tensor. Must have the same type as ref. A tensor of updated values

to add to `input`.

Returns A `Tensor` with the same shape as `input`, containing values of `input` updated with `updates`.

[7, 8]]

```

More specifically, this op outputs a copy of the input tensor where values from the `height` and `width` dimensions are moved to the `batch` dimension. After the zero-padding, both `height` and `width` of the input must be divisible by the block size.

Arguments:

The attr `block_size` must be greater than one. It indicates the block size.

Non-overlapping blocks of size `block_size x block size` in the height and width dimensions are rearranged into the batch dimension at each location.
The batch of the output tensor is `batch * block_size * block_size`.
Both height_pad and width_pad must be divisible by block_size.

The shape of the output will be:

[batch*block_size*block_size, height_pad/block_size, width_pad/block_size,
 depth]

```

``` x = [[[[1], [2], [3], [4]],

 [[5],   [6],  [7],  [8]]],
[[[9],  [10], [11],  [12]],
 [[13], [14], [15],  [16]]]]

```

The output tensor has shape `[8, 1, 2, 1]` and value:

Prior to division into blocks, the spatial dimensions of the input are optionally zero padded according to `paddings`. See below for a precise description.

Arguments:

input: N-D with shape `input_shape = [batch] + spatial_shape + remaining_shape`,

where spatial_shape has `M` dimensions.

	block_shape: 1-D with shape `[M]`, all values must be >= 1.
	paddings: 2-D with shape `[M, 2]`, all values must be >= 0.
  `paddings[i] = [pad_start, pad_end]` specifies the padding for input dimension
  `i + 1`, which corresponds to spatial dimension `i`.  It is required that
  `block_shape[i]` divides `input_shape[i + 1] + pad_start + pad_end`.

This operation is equivalent to the following steps:

Zero-pad the start and end of dimensions `[1, ..., M]` of the input according to `paddings` to produce `padded` of shape `padded_shape`.

2. Reshape `padded` to `reshaped_padded` of shape:

[batch] +
[padded_shape[1] / block_shape[0],
  block_shape[0],
 ...,
 padded_shape[M] / block_shape[M-1],
 block_shape[M-1]] +
remaining_shape

Permute dimensions of `reshaped_padded` to produce `permuted_reshaped_padded` of shape:
block_shape + [batch] + [padded_shape[1] / block_shape[0], ..., padded_shape[M] / block_shape[M-1]] + remaining_shape

Reshape `permuted_reshaped_padded` to flatten `block_shape` into the batch dimension, producing an output tensor of shape:
[batch * prod(block_shape)] + [padded_shape[1] / block_shape[0], ..., padded_shape[M] / block_shape[M-1]] + remaining_shape

Some examples:

(1) For the following input of shape `[1, 2, 2, 1]`, `block_shape = [2, 2]`, and

`paddings = [[0, 0], [0, 0]]`:

``` x = [[[[1], [2]], [[3], [4]]]] ```

The output tensor has shape `[4, 1, 1, 1]` and value:

``` [[[[1]]], [[[2]]], [[[3]]], [[[4]]]] ```

(2) For the following input of shape `[1, 2, 2, 3]`, `block_shape = [2, 2]`, and

`paddings = [[0, 0], [0, 0]]`:

``` x = [[[[1, 2, 3], [4, 5, 6]],

[[7, 8, 9], [10, 11, 12]]]]

```

The output tensor has shape `[4, 1, 1, 3]` and value:

``` [[[[1, 2, 3]]], [[[4, 5, 6]]], [[[7, 8, 9]]], [[[10, 11, 12]]]] ```

(3) For the following input of shape `[1, 4, 4, 1]`, `block_shape = [2, 2]`, and

`paddings = [[0, 0], [0, 0]]`:

``` x = [[[[1], [2], [3], [4]],

[[5],   [6],  [7],  [8]],
[[9],  [10], [11],  [12]],
[[13], [14], [15],  [16]]]]

```

The output tensor has shape `[4, 2, 2, 1]` and value:

``` x = [[[[1], [3]], [[9], [11]]],

[[[2], [4]], [[10], [12]]],
[[[5], [7]], [[13], [15]]],
[[[6], [8]], [[14], [16]]]]

```

(4) For the following input of shape `[2, 2, 4, 1]`, block_shape = `[2, 2]`, and

paddings = `[[0, 0], [2, 0]]`:

``` x = [[[[1], [2], [3], [4]],

 [[5],   [6],  [7],  [8]]],
[[[9],  [10], [11],  [12]],
 [[13], [14], [15],  [16]]]]

```

The output tensor has shape `[8, 1, 3, 1]` and value:

``` x = [[[[0], [1], [3]]], [[[0], [9], [11]]],

[[[0], [2], [4]]], [[[0], [10], [12]]],
[[[0], [5], [7]]], [[[0], [13], [15]]],
[[[0], [6], [8]]], [[[0], [14], [16]]]]

```

Among others, this operation is useful for reducing atrous convolution into regular convolution.

func SpaceToDepth ¶ added in v1.1.0

func SpaceToDepth(scope *Scope, input tf.Output, block_size int64, optional ...SpaceToDepthAttr) (output tf.Output)

SpaceToDepth for tensors of type T.

Rearranges blocks of spatial data, into depth. More specifically, this op outputs a copy of the input tensor where values from the `height` and `width` dimensions are moved to the `depth` dimension. The attr `block_size` indicates the input block size.

Non-overlapping blocks of size `block_size x block size` are rearranged into depth at each location.
The depth of the output tensor is `block_size * block_size * input_depth`.
The Y, X coordinates within each block of the input become the high order component of the output channel index.
The input tensor's height and width must be divisible by block_size.

The `data_format` attr specifies the layout of the input and output tensors with the following options:

"NHWC": `[ batch, height, width, channels ]`
"NCHW": `[ batch, channels, height, width ]`
"NCHW_VECT_C":
    `qint8 [ batch, channels / 4, height, width, 4 ]`

It is useful to consider the operation as transforming a 6-D Tensor. e.g. for data_format = NHWC,

Each element in the input tensor can be specified via 6 coordinates,
ordered by decreasing memory layout significance as:
n,oY,bY,oX,bX,iC  (where n=batch index, oX, oY means X or Y coordinates
                   within the output image, bX, bY means coordinates
                   within the input block, iC means input channels).
The output would be a transpose to the following layout:
n,oY,oX,bY,bX,iC

This operation is useful for resizing the activations between convolutions (but keeping all data), e.g. instead of pooling. It is also useful for training purely convolutional models.

For example, given an input of shape `[1, 2, 2, 1]`, data_format = "NHWC" and block_size = 2:

``` x = [[[[1], [2]],

[[3], [4]]]]

```

This operation will output a tensor of shape `[1, 1, 1, 4]`:

``` [[[[1, 2, 3, 4]]]] ```

Here, the input has a batch of 1 and each batch element has shape `[2, 2, 1]`, the corresponding output will have a single element (i.e. width and height are both 1) and will have a depth of 4 channels (1 * block_size * block_size). The output element shape is `[1, 1, 4]`.

For an input tensor with larger depth, here of shape `[1, 2, 2, 3]`, e.g.

``` x = [[[[1, 2, 3], [4, 5, 6]],

[[7, 8, 9], [10, 11, 12]]]]

```

This operation, for block_size of 2, will return the following tensor of shape `[1, 1, 1, 12]`

``` [[[[1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12]]]] ```

Similarly, for the following input of shape `[1 4 4 1]`, and a block size of 2:

``` x = [[[[1], [2], [5], [6]],

[[3],   [4],  [7],  [8]],
[[9],  [10], [13],  [14]],
[[11], [12], [15],  [16]]]]

```

the operator will return the following tensor of shape `[1 2 2 4]`:

``` x = [[[[1, 2, 3, 4],

 [5, 6, 7, 8]],
[[9, 10, 11, 12],
 [13, 14, 15, 16]]]]

```

Arguments:

block_size: The size of the spatial block.

func SparseAdd ¶ added in v1.1.0

func SparseAdd(scope *Scope, a_indices tf.Output, a_values tf.Output, a_shape tf.Output, b_indices tf.Output, b_values tf.Output, b_shape tf.Output, thresh tf.Output) (sum_indices tf.Output, sum_values tf.Output, sum_shape tf.Output)

Adds two `SparseTensor` objects to produce another `SparseTensor`.

The input `SparseTensor` objects' indices are assumed ordered in standard lexicographic order. If this is not the case, before this step run `SparseReorder` to restore index ordering.

By default, if two values sum to zero at some index, the output `SparseTensor` would still include that particular location in its index, storing a zero in the corresponding value slot. To override this, callers can specify `thresh`, indicating that if the sum has a magnitude strictly smaller than `thresh`, its corresponding value and index would then not be included. In particular, `thresh == 0` (default) means everything is kept and actual thresholding happens only for a positive value.

In the following shapes, `nnz` is the count after taking `thresh` into account.

Arguments:

a_indices: 2-D.  The `indices` of the first `SparseTensor`, size `[nnz, ndims]` Matrix.
a_values: 1-D.  The `values` of the first `SparseTensor`, size `[nnz]` Vector.
a_shape: 1-D.  The `shape` of the first `SparseTensor`, size `[ndims]` Vector.
b_indices: 2-D.  The `indices` of the second `SparseTensor`, size `[nnz, ndims]` Matrix.
b_values: 1-D.  The `values` of the second `SparseTensor`, size `[nnz]` Vector.
b_shape: 1-D.  The `shape` of the second `SparseTensor`, size `[ndims]` Vector.
thresh: 0-D.  The magnitude threshold that determines if an output value/index

pair takes space.

func SparseAddGrad ¶ added in v1.1.0

func SparseAddGrad(scope *Scope, backprop_val_grad tf.Output, a_indices tf.Output, b_indices tf.Output, sum_indices tf.Output) (a_val_grad tf.Output, b_val_grad tf.Output)

The gradient operator for the SparseAdd op.

The SparseAdd op calculates A + B, where A, B, and the sum are all represented as `SparseTensor` objects. This op takes in the upstream gradient w.r.t. non-empty values of the sum, and outputs the gradients w.r.t. the non-empty values of A and B.

Arguments:

backprop_val_grad: 1-D with shape `[nnz(sum)]`.  The gradient with respect to

the non-empty values of the sum.

a_indices: 2-D.  The `indices` of the `SparseTensor` A, size `[nnz(A), ndims]`.
b_indices: 2-D.  The `indices` of the `SparseTensor` B, size `[nnz(B), ndims]`.
sum_indices: 2-D.  The `indices` of the sum `SparseTensor`, size

`[nnz(sum), ndims]`.

Returns 1-D with shape `[nnz(A)]`. The gradient with respect to the non-empty values of A.1-D with shape `[nnz(B)]`. The gradient with respect to the non-empty values of B.

func SparseConcat ¶ added in v1.1.0

func SparseConcat(scope *Scope, indices []tf.Output, values []tf.Output, shapes []tf.Output, concat_dim int64) (output_indices tf.Output, output_values tf.Output, output_shape tf.Output)

Concatenates a list of `SparseTensor` along the specified dimension.

Concatenation is with respect to the dense versions of these sparse tensors. It is assumed that each input is a `SparseTensor` whose elements are ordered along increasing dimension number.

All inputs' shapes must match, except for the concat dimension. The `indices`, `values`, and `shapes` lists must have the same length.

The output shape is identical to the inputs', except along the concat dimension, where it is the sum of the inputs' sizes along that dimension.

The output elements will be resorted to preserve the sort order along increasing dimension number.

This op runs in `O(M log M)` time, where `M` is the total number of non-empty values across all inputs. This is due to the need for an internal sort in order to concatenate efficiently across an arbitrary dimension.

For example, if `concat_dim = 1` and the inputs are

sp_inputs[0]: shape = [2, 3]
[0, 2]: "a"
[1, 0]: "b"
[1, 1]: "c"

sp_inputs[1]: shape = [2, 4]
[0, 1]: "d"
[0, 2]: "e"

then the output will be

shape = [2, 7]
[0, 2]: "a"
[0, 4]: "d"
[0, 5]: "e"
[1, 0]: "b"
[1, 1]: "c"

Graphically this is equivalent to doing

[    a] concat [  d e  ] = [    a   d e  ]
[b c  ]        [       ]   [b c          ]

values: 1-D.  Non-empty values of each `SparseTensor`.
shapes: 1-D.  Shapes of each `SparseTensor`.
concat_dim: Dimension to concatenate along. Must be in range [-rank, rank),

where rank is the number of dimensions in each input `SparseTensor`.

Returns 2-D. Indices of the concatenated `SparseTensor`.1-D. Non-empty values of the concatenated `SparseTensor`.1-D. Shape of the concatenated `SparseTensor`.

func SparseCross ¶ added in v1.2.0

func SparseCross(scope *Scope, indices []tf.Output, values []tf.Output, shapes []tf.Output, dense_inputs []tf.Output, hashed_output bool, num_buckets int64, hash_key int64, out_type tf.DataType, internal_type tf.DataType) (output_indices tf.Output, output_values tf.Output, output_shape tf.Output)

Generates sparse cross from a list of sparse and dense tensors.

The op takes two lists, one of 2D `SparseTensor` and one of 2D `Tensor`, each representing features of one feature column. It outputs a 2D `SparseTensor` with the batchwise crosses of these features.

For example, if the inputs are

inputs[0]: SparseTensor with shape = [2, 2]
[0, 0]: "a"
[1, 0]: "b"
[1, 1]: "c"

inputs[1]: SparseTensor with shape = [2, 1]
[0, 0]: "d"
[1, 0]: "e"

inputs[2]: Tensor [["f"], ["g"]]

then the output will be

shape = [2, 2]
[0, 0]: "a_X_d_X_f"
[1, 0]: "b_X_e_X_g"
[1, 1]: "c_X_e_X_g"

if hashed_output=true then the output will be

shape = [2, 2]
[0, 0]: FingerprintCat64(
            Fingerprint64("f"), FingerprintCat64(
                Fingerprint64("d"), Fingerprint64("a")))
[1, 0]: FingerprintCat64(
            Fingerprint64("g"), FingerprintCat64(
                Fingerprint64("e"), Fingerprint64("b")))
[1, 1]: FingerprintCat64(
            Fingerprint64("g"), FingerprintCat64(
                Fingerprint64("e"), Fingerprint64("c")))

Arguments:

indices: 2-D.  Indices of each input `SparseTensor`.
values: 1-D.   values of each `SparseTensor`.
shapes: 1-D.   Shapes of each `SparseTensor`.
dense_inputs: 2-D.    Columns represented by dense `Tensor`.
hashed_output: If true, returns the hash of the cross instead of the string.

This will allow us avoiding string manipulations.

num_buckets: It is used if hashed_output is true.

output = hashed_value%num_buckets if num_buckets > 0 else hashed_value.

hash_key: Specify the hash_key that will be used by the `FingerprintCat64`

function to combine the crosses fingerprints.

Returns 2-D. Indices of the concatenated `SparseTensor`.1-D. Non-empty values of the concatenated or hashed `SparseTensor`.1-D. Shape of the concatenated `SparseTensor`.

func SparseDenseCwiseAdd ¶ added in v1.1.0

func SparseDenseCwiseAdd(scope *Scope, sp_indices tf.Output, sp_values tf.Output, sp_shape tf.Output, dense tf.Output) (output tf.Output)

Adds up a SparseTensor and a dense Tensor, using these special rules:

(1) Broadcasts the dense side to have the same shape as the sparse side, if

eligible;

(2) Then, only the dense values pointed to by the indices of the SparseTensor

participate in the cwise addition.

By these rules, the result is a logical SparseTensor with exactly the same indices and shape, but possibly with different non-zero values. The output of this Op is the resultant non-zero values.

Component-wise divides a SparseTensor by a dense Tensor.

*Limitation*: this Op only broadcasts the dense side to the sparse side, but not the other direction.

Arguments:

SparseTensor, possibly not in canonical ordering.

sp_values: 1-D.  `N` non-empty values corresponding to `sp_indices`.

func SparseDenseCwiseMul ¶ added in v1.1.0

func SparseDenseCwiseMul(scope *Scope, sp_indices tf.Output, sp_values tf.Output, sp_shape tf.Output, dense tf.Output) (output tf.Output)

Component-wise multiplies a SparseTensor by a dense Tensor.

The output locations corresponding to the implicitly zero elements in the sparse tensor will be zero (i.e., will not take up storage space), regardless of the contents of the dense tensor (even if it's +/-INF and that INF*0 == NaN).

*Limitation*: this Op only broadcasts the dense side to the sparse side, but not the other direction.

Arguments:

func SparseFillEmptyRows ¶ added in v1.3.0

func SparseFillEmptyRows(scope *Scope, indices tf.Output, values tf.Output, dense_shape tf.Output, default_value tf.Output) (output_indices tf.Output, output_values tf.Output, empty_row_indicator tf.Output, reverse_index_map tf.Output)

Fills empty rows in the input 2-D `SparseTensor` with a default value.

The input `SparseTensor` is represented via the tuple of inputs (`indices`, `values`, `dense_shape`). The output `SparseTensor` has the same `dense_shape` but with indices `output_indices` and values `output_values`.

This op inserts a single entry for every row that doesn't have any values. The index is created as `[row, 0, ..., 0]` and the inserted value is `default_value`.

For example, suppose `sp_input` has shape `[5, 6]` and non-empty values:

[0, 1]: a
[0, 3]: b
[2, 0]: c
[3, 1]: d

Rows 1 and 4 are empty, so the output will be of shape `[5, 6]` with values:

[0, 1]: a
[0, 3]: b
[1, 0]: default_value
[2, 0]: c
[3, 1]: d
[4, 0]: default_value

The output `SparseTensor` will be in row-major order and will have the same shape as the input.

This op also returns an indicator vector shaped `[dense_shape[0]]` such that

empty_row_indicator[i] = True iff row i was an empty row.

And a reverse index map vector shaped `[indices.shape[0]]` that is used during backpropagation,

reverse_index_map[j] = out_j s.t. indices[j, :] == output_indices[out_j, :]

Arguments:

func SparseFillEmptyRowsGrad ¶ added in v1.3.0

func SparseFillEmptyRowsGrad(scope *Scope, reverse_index_map tf.Output, grad_values tf.Output) (d_values tf.Output, d_default_value tf.Output)

The gradient of SparseFillEmptyRows.

Takes vectors reverse_index_map, shaped `[N]`, and grad_values, shaped `[N_full]`, where `N_full >= N` and copies data into either `d_values` or `d_default_value`. Here `d_values` is shaped `[N]` and `d_default_value` is a scalar.

d_values[j] = grad_values[reverse_index_map[j]]
d_default_value = sum_{k : 0 .. N_full - 1} (
   grad_values[k] * 1{k not in reverse_index_map})

Arguments:

reverse_index_map: 1-D.  The reverse index map from SparseFillEmptyRows.
grad_values: 1-D.  The gradients from backprop.

Returns 1-D. The backprop into values.0-D. The backprop into default_value.

func SparseMatMul ¶ added in v1.1.0

func SparseMatMul(scope *Scope, a tf.Output, b tf.Output, optional ...SparseMatMulAttr) (product tf.Output)

Multiply matrix "a" by matrix "b".

The inputs must be two-dimensional matrices and the inner dimension of "a" must match the outer dimension of "b". Both "a" and "b" must be `Tensor`s not `SparseTensor`s. This op is optimized for the case where at least one of "a" or "b" is sparse, in the sense that they have a large proportion of zero values. The breakeven for using this versus a dense matrix multiply on one platform was 30% zero values in the sparse matrix.

The gradient computation of this operation will only take advantage of sparsity in the input gradient when that gradient comes from a Relu.

func SparseReduceMax ¶ added in v1.3.0

func SparseReduceMax(scope *Scope, input_indices tf.Output, input_values tf.Output, input_shape tf.Output, reduction_axes tf.Output, optional ...SparseReduceMaxAttr) (output tf.Output)

Computes the max of elements across dimensions of a SparseTensor.

This Op takes a SparseTensor and is the sparse counterpart to `tf.reduce_max()`. In particular, this Op also returns a dense `Tensor` instead of a sparse one.

Reduces `sp_input` along the dimensions given in `reduction_axes`. Unless `keep_dims` is true, the rank of the tensor is reduced by 1 for each entry in `reduction_axes`. If `keep_dims` is true, the reduced dimensions are retained with length 1.

If `reduction_axes` has no entries, all dimensions are reduced, and a tensor with a single element is returned. Additionally, the axes can be negative, which are interpreted according to the indexing rules in Python.

Arguments:

input_indices: 2-D.  `N x R` matrix with the indices of non-empty values in a

SparseTensor, possibly not in canonical ordering.

input_values: 1-D.  `N` non-empty values corresponding to `input_indices`.

Computes the sum of elements across dimensions of a SparseTensor.

This Op takes a SparseTensor and is the sparse counterpart to `tf.reduce_sum()`. In particular, this Op also returns a dense `Tensor` instead of a sparse one.

Reduces `sp_input` along the dimensions given in `reduction_axes`. Unless `keep_dims` is true, the rank of the tensor is reduced by 1 for each entry in `reduction_axes`. If `keep_dims` is true, the reduced dimensions are retained with length 1.

func SparseReorder ¶ added in v1.1.0

func SparseReorder(scope *Scope, input_indices tf.Output, input_values tf.Output, input_shape tf.Output) (output_indices tf.Output, output_values tf.Output)

Reorders a SparseTensor into the canonical, row-major ordering.

Note that by convention, all sparse ops preserve the canonical ordering along increasing dimension number. The only time ordering can be violated is during manual manipulation of the indices and values vectors to add entries.

Reordering does not affect the shape of the SparseTensor.

If the tensor has rank `R` and `N` non-empty values, `input_indices` has shape `[N, R]`, input_values has length `N`, and input_shape has length `R`.

Arguments:

input_indices: 2-D.  `N x R` matrix with the indices of non-empty values in a

SparseTensor, possibly not in canonical ordering.

input_values: 1-D.  `N` non-empty values corresponding to `input_indices`.

func SparseReshape(scope *Scope, input_indices tf.Output, input_shape tf.Output, new_shape tf.Output) (output_indices tf.Output, output_shape tf.Output)

Reshapes a SparseTensor to represent values in a new dense shape.

This operation has the same semantics as reshape on the represented dense tensor. The `input_indices` are recomputed based on the requested `new_shape`.

If one component of `new_shape` is the special value -1, the size of that dimension is computed so that the total dense size remains constant. At most one component of `new_shape` can be -1. The number of dense elements implied by `new_shape` must be the same as the number of dense elements originally implied by `input_shape`.

Reshaping does not affect the order of values in the SparseTensor.

If the input tensor has rank `R_in` and `N` non-empty values, and `new_shape` has length `R_out`, then `input_indices` has shape `[N, R_in]`, `input_shape` has length `R_in`, `output_indices` has shape `[N, R_out]`, and `output_shape` has length `R_out`.

Arguments:

input_indices: 2-D.  `N x R_in` matrix with the indices of non-empty values in a

SparseTensor.

input_shape: 1-D.  `R_in` vector with the input SparseTensor's dense shape.

Returns 2-D. `N x R_out` matrix with the updated indices of non-empty values in the output SparseTensor.1-D. `R_out` vector with the full dense shape of the output SparseTensor. This is the same as `new_shape` but with any -1 dimensions filled in.

Returns the created operation.

func StopGradient ¶ added in v1.1.0

func StopGradient(scope *Scope, input tf.Output) (output tf.Output)

Stops gradient computation.

When executed in a graph, this op outputs its input tensor as-is.

When building ops to compute gradients, this op prevents the contribution of its inputs to be taken into account. Normally, the gradient generator adds ops to a graph to compute the derivatives of a specified 'loss' by recursively finding out inputs that contributed to its computation. If you insert this op in the graph it inputs are masked from the gradient generator. They are not taken into account for computing gradients.

This is useful any time you want to compute a value with TensorFlow but need to pretend that the value was a constant. Some examples include:

The *EM* algorithm where the *M-step* should not involve backpropagation through the output of the *E-step*.
Contrastive divergence training of Boltzmann machines where, when differentiating the energy function, the training must not backpropagate through the graph that generated the samples from the model.
Adversarial training, where no backprop should happen through the adversarial example generation process.

func StridedSlice ¶ added in v1.1.0

func StridedSlice(scope *Scope, input tf.Output, begin tf.Output, end tf.Output, strides tf.Output, optional ...StridedSliceAttr) (output tf.Output)

Return a strided slice from `input`.

Note, most python users will want to use the Python `Tensor.__getitem__` or `Variable.__getitem__` rather than this op directly.

The goal of this op is to produce a new tensor with a subset of the elements from the `n` dimensional `input` tensor. The subset is chosen using a sequence of `m` sparse range specifications encoded into the arguments of this function. Note, in some cases `m` could be equal to `n`, but this need not be the case. Each range specification entry can be one of the following:

An ellipsis (...). Ellipses are used to imply zero or more dimensions of full-dimension selection and are produced using `ellipsis_mask`. For example, `foo[...]` is the identity slice.

A new axis. This is used to insert a new shape=1 dimension and is produced using `new_axis_mask`. For example, `foo[:, ...]` where `foo` is shape `(3, 4)` produces a `(1, 3, 4)` tensor.

A range `begin:end:stride`. This is used to specify how much to choose from a given dimension. `stride` can be any integer but 0. `begin` is an integer which represents the index of the first value to select while `end` represents the index of the last value to select. The number of values selected in each dimension is `end - begin` if `stride > 0` and `begin - end` if `stride < 0`. `begin` and `end` can be negative where `-1` is the last element, `-2` is the second to last. `begin_mask` controls whether to replace the explicitly given `begin` with an implicit effective value of `0` if `stride > 0` and `-1` if `stride < 0`. `end_mask` is analogous but produces the number required to create the largest open interval. For example, given a shape `(3,)` tensor `foo[:]`, the effective `begin` and `end` are `0` and `3`. Do not assume this is equivalent to `foo[0:-1]` which has an effective `begin` and `end` of `0` and `2`. Another example is `foo[-2::-1]` which reverses the first dimension of a tensor while dropping the last two (in the original order elements). For example `foo = [1,2,3,4]; foo[-2::-1]` is `[4,3]`.

A single index. This is used to keep only elements that have a given index. For example (`foo[2, :]` on a shape `(5,6)` tensor produces a shape `(6,)` tensor. This is encoded in `begin` and `end` and `shrink_axis_mask`.

Each conceptual range specification is encoded in the op's argument. This encoding is best understand by considering a non-trivial example. In particular, `foo[1, 2:4, None, ..., :-3:-1, :]` will be encoded as

``` begin = [1, 2, x, x, 0, x] # x denotes don't care (usually 0) end = [2, 4, x, x, -3, x] strides = [1, 1, x, x, -1, 1] begin_mask = 1<<4 | 1 << 5 = 48 end_mask = 1<<5 = 32 ellipsis_mask = 1<<3 = 8 new_axis_mask = 1<<2 4 shrink_axis_mask = 1<<0 ```

In this case if `foo.shape` is (5, 5, 5, 5, 5, 5) the final shape of the slice becomes (2, 1, 5, 5, 2, 5). Let us walk step by step through each argument specification.

1. The first argument in the example slice is turned into `begin = 1` and `end = begin + 1 = 2`. To disambiguate from the original spec `2:4` we also set the appropriate bit in `shrink_axis_mask`.

2. `2:4` is contributes 2, 4, 1 to begin, end, and stride. All masks have zero bits contributed.

3. None is a synonym for `tf.newaxis`. This means insert a dimension of size 1 dimension in the final shape. Dummy values are contributed to begin, end and stride, while the new_axis_mask bit is set.

4. `...` grab the full ranges from as many dimensions as needed to fully specify a slice for every dimension of the input shape.

5. `:-3:-1` shows the use of negative indices. A negative index `i` associated with a dimension that has shape `s` is converted to a positive index `s + i`. So `-1` becomes `s-1` (i.e. the last element). This conversion is done internally so begin, end and strides receive x, -3, and -1. The appropriate begin_mask bit is set to indicate the start range is the full range (ignoring the x).

6. `:` indicates that the entire contents of the corresponding dimension is selected. This is equivalent to `::` or `0::1`. begin, end, and strides receive 0, 0, and 1, respectively. The appropriate bits in `begin_mask` and `end_mask` are also set.

*Requirements*:

`0 != strides[i] for i in [0, m)`
`ellipsis_mask must be a power of two (only one ellipsis)`

Arguments:

begin: `begin[k]` specifies the offset into the `k`th range specification.

The exact dimension this corresponds to will be determined by context. Out-of-bounds values will be silently clamped. If the `k`th bit of `begin_mask` then `begin[k]` is ignored and the full range of the appropriate dimension is used instead. Negative values causes indexing to start from the highest element e.g. If `foo==[1,2,3]` then `foo[-1]==3`.

end: `end[i]` is like `begin` with the exception that `end_mask` is

used to determine full ranges.

strides: `strides[i]` specifies the increment in the `i`th specification

after extracting a given element. Negative indices will reverse the original order. Out or range values are clamped to `[0,dim[i]) if slice[i]>0` or `[-1,dim[i]-1] if slice[i] < 0`

func StridedSliceGrad ¶ added in v1.1.0

func StridedSliceGrad(scope *Scope, shape tf.Output, begin tf.Output, end tf.Output, strides tf.Output, dy tf.Output, optional ...StridedSliceGradAttr) (output tf.Output)

Returns the gradient of `StridedSlice`.

Since `StridedSlice` cuts out pieces of its `input` which is size `shape`, its gradient will have the same shape (which is passed here as `shape`). The gradient will be zero in any element that the slice does not select.

Arguments are the same as StridedSliceGrad with the exception that `dy` is the input gradient to be propagated and `shape` is the shape of `StridedSlice`'s `input`.

func StringFormat ¶ added in v1.12.0

func StringJoin ¶ added in v1.1.0

func StringJoin(scope *Scope, inputs []tf.Output, optional ...StringJoinAttr) (output tf.Output)

Joins the strings in the given list of string tensors into one tensor;

with the given separator (default is an empty separator).

Arguments:

inputs: A list of string tensors.  The tensors must all have the same shape,

or be scalars. Scalars may be mixed in; these will be broadcast to the shape of non-scalar inputs.

func StringLength ¶ added in v1.12.0

func StringLength(scope *Scope, input tf.Output, optional ...StringLengthAttr) (output tf.Output)

String lengths of `input`.

Computes the length of each string given in the input tensor.

Arguments:

input: The string for which to compute the length.

Returns Integer tensor that has the same shape as `input`. The output contains the element-wise string lengths of `input`.

func StringSplit ¶ added in v1.1.0

func StringSplit(scope *Scope, input tf.Output, delimiter tf.Output, optional ...StringSplitAttr) (indices tf.Output, values tf.Output, shape tf.Output)

Split elements of `input` based on `delimiter` into a `SparseTensor`.

Let N be the size of source (typically N will be the batch size). Split each element of `input` based on `delimiter` and return a `SparseTensor` containing the splitted tokens. Empty tokens are ignored.

`delimiter` can be empty, or a string of split characters. If `delimiter` is an

empty string, each element of `input` is split into individual single-byte
character strings, including splitting of UTF-8 multibyte sequences. Otherwise
every character of `delimiter` is a potential split point.

For example:

N = 2, input[0] is 'hello world' and input[1] is 'a b c', then the output
will be

indices = [0, 0;
           0, 1;
           1, 0;
           1, 1;
           1, 2]
shape = [2, 3]
values = ['hello', 'world', 'a', 'b', 'c']

Arguments:

input: 1-D. Strings to split.
delimiter: 0-D. Delimiter characters (bytes), or empty string.

Returns A dense matrix of int64 representing the indices of the sparse tensor.A vector of strings corresponding to the splited values.a length-2 vector of int64 representing the shape of the sparse tensor, where the first value is N and the second value is the maximum number of tokens in a single input entry.

func StringSplitV2 ¶ added in v1.11.0

func StringSplitV2(scope *Scope, input tf.Output, sep tf.Output, optional ...StringSplitV2Attr) (indices tf.Output, values tf.Output, shape tf.Output)

Split elements of `source` based on `sep` into a `SparseTensor`.

Let N be the size of source (typically N will be the batch size). Split each element of `source` based on `sep` and return a `SparseTensor` containing the split tokens. Empty tokens are ignored.

For example, N = 2, source[0] is 'hello world' and source[1] is 'a b c', then the output will be ``` st.indices = [0, 0;

0, 1;
1, 0;
1, 1;
1, 2]

st.shape = [2, 3] st.values = ['hello', 'world', 'a', 'b', 'c'] ```

If `sep` is given, consecutive delimiters are not grouped together and are deemed to delimit empty strings. For example, source of `"1<>2<><>3"` and sep of `"<>"` returns `["1", "2", "", "3"]`. If `sep` is None or an empty string, consecutive whitespace are regarded as a single separator, and the result will contain no empty strings at the startor end if the string has leading or trailing whitespace.

Note that the above mentioned behavior matches python's str.split.

Arguments:

input: `1-D` string `Tensor`, the strings to split.
sep: `0-D` string `Tensor`, the delimiter character.

func StringStrip ¶ added in v1.11.0

func StringStrip(scope *Scope, input tf.Output) (output tf.Output)

Strip leading and trailing whitespaces from the Tensor.

Arguments:

input: A string `Tensor` of any shape.

Returns A string `Tensor` of the same shape as the input.

func StringToHashBucket ¶ added in v1.1.0

func StringToHashBucket(scope *Scope, string_tensor tf.Output, num_buckets int64) (output tf.Output)

Converts each string in the input Tensor to its hash mod by a number of buckets.

The hash function is deterministic on the content of the string within the process.

Note that the hash function may change from time to time. This functionality will be deprecated and it's recommended to use `tf.string_to_hash_bucket_fast()` or `tf.string_to_hash_bucket_strong()`.

Arguments:

num_buckets: The number of buckets.

Returns A Tensor of the same shape as the input `string_tensor`.

func StringToHashBucketFast ¶ added in v1.1.0

func StringToHashBucketFast(scope *Scope, input tf.Output, num_buckets int64) (output tf.Output)

Converts each string in the input Tensor to its hash mod by a number of buckets.

The hash function is deterministic on the content of the string within the process and will never change. However, it is not suitable for cryptography. This function may be used when CPU time is scarce and inputs are trusted or unimportant. There is a risk of adversaries constructing inputs that all hash to the same bucket. To prevent this problem, use a strong hash function with `tf.string_to_hash_bucket_strong`.

Arguments:

input: The strings to assign a hash bucket.
num_buckets: The number of buckets.

Returns A Tensor of the same shape as the input `string_tensor`.

func StringToHashBucketStrong ¶ added in v1.1.0

func StringToHashBucketStrong(scope *Scope, input tf.Output, num_buckets int64, key []int64) (output tf.Output)

Converts each string in the input Tensor to its hash mod by a number of buckets.

The hash function is deterministic on the content of the string within the process. The hash function is a keyed hash function, where attribute `key` defines the key of the hash function. `key` is an array of 2 elements.

A strong hash is important when inputs may be malicious, e.g. URLs with additional components. Adversaries could try to make their inputs hash to the same bucket for a denial-of-service attack or to skew the results. A strong hash can be used to make it difficult to find inputs with a skewed hash value distribution over buckets. This requires that the hash function is seeded by a high-entropy (random) "key" unknown to the adversary.

The additional robustness comes at a cost of roughly 4x higher compute time than `tf.string_to_hash_bucket_fast`.

Arguments:

input: The strings to assign a hash bucket.
num_buckets: The number of buckets.
key: The key used to seed the hash function, passed as a list of two uint64

elements.

Returns A Tensor of the same shape as the input `string_tensor`.

func StringToNumber ¶ added in v1.1.0

func StringToNumber(scope *Scope, string_tensor tf.Output, optional ...StringToNumberAttr) (output tf.Output)

Converts each string in the input Tensor to the specified numeric type.

(Note that int32 overflow results in an error while float overflow results in a rounded value.)

Returns A Tensor of the same shape as the input `string_tensor`.

func Sub ¶ added in v1.1.0

func Sub(scope *Scope, x tf.Output, y tf.Output) (z tf.Output)

Returns x - y element-wise.

*NOTE*: `Subtract` supports broadcasting. More about broadcasting [here](http://docs.scipy.org/doc/numpy/user/basics.broadcasting.html)

func Substr ¶ added in v1.1.0

func Substr(scope *Scope, input tf.Output, pos tf.Output, len tf.Output, optional ...SubstrAttr) (output tf.Output)

Return substrings from `Tensor` of strings.

For each string in the input `Tensor`, creates a substring starting at index `pos` with a total length of `len`.

If `len` defines a substring that would extend beyond the length of the input string, then as many characters as possible are used.

A negative `pos` indicates distance within the string backwards from the end.

If `pos` specifies an index which is out of range for any of the input strings, then an `InvalidArgumentError` is thrown.

`pos` and `len` must have the same shape, otherwise a `ValueError` is thrown on Op creation.

*NOTE*: `Substr` supports broadcasting up to two dimensions. More about broadcasting [here](http://docs.scipy.org/doc/numpy/user/basics.broadcasting.html)

The input `sparse_handles` must be an `int64` matrix of shape `[N, 1]` where `N` is the minibatch size and the rows correspond to the output handles of `AddSparseToTensorsMap` or `AddManySparseToTensorsMap`.

```

index = [ 0]
        [10]

        [0 10]
        [0 20]
        [1  2]
        [1 10]

func TensorArrayGradV3 ¶ added in v1.1.0

func TensorArrayGradV3(scope *Scope, handle tf.Output, flow_in tf.Output, source string) (grad_handle tf.Output, flow_out tf.Output)

Creates a TensorArray for storing the gradients of values in the given handle.

If the given TensorArray gradient already exists, returns a reference to it.

Locks the size of the original TensorArray by disabling its dynamic size flag.

**A note about the input flow_in:**

The handle flow_in forces the execution of the gradient lookup to occur only after certain other operations have occurred. For example, when the forward TensorArray is dynamically sized, writes to this TensorArray may resize the object. The gradient TensorArray is statically sized based on the size of the forward TensorArray when this operation executes. Furthermore, the size of the forward TensorArray is frozen by this call. As a result, the flow is used to ensure that the call to generate the gradient TensorArray only happens after all writes are executed.

In the case of dynamically sized TensorArrays, gradient computation should only be performed on read operations that have themselves been chained via flow to occur only after all writes have executed. That way the final size of the forward TensorArray is known when this operation is called.

**A note about the source attribute:**

TensorArray gradient calls use an accumulator TensorArray object. If multiple gradients are calculated and run in the same session, the multiple gradient nodes may accidentally flow through the same accumulator TensorArray. This double counts and generally breaks the TensorArray gradient flow.

The solution is to identify which gradient call this particular TensorArray gradient is being called in. This is performed by identifying a unique string (e.g. "gradients", "gradients_1", ...) from the input gradient Tensor's name. This string is used as a suffix when creating the TensorArray gradient object here (the attribute `source`).

The attribute `source` is added as a suffix to the forward TensorArray's name when performing the creation / lookup, so that each separate gradient calculation gets its own TensorArray accumulator.

Arguments:

handle: The handle to the forward TensorArray.
flow_in: A float scalar that enforces proper chaining of operations.
source: The gradient source string, used to decide which gradient TensorArray

to return.

func TensorArrayGradWithShape ¶ added in v1.11.0

flow_in: A float scalar that enforces proper chaining of operations.
shape_to_prepend: An int32 vector representing a shape. Elements in the gradient accumulator will

This operation creates a new tensor by adding sparse `updates` to the passed in `tensor`. This operation is very similar to `tf.scatter_nd_add`, except that the updates are added onto an existing tensor (as opposed to a variable). If the memory for the existing tensor cannot be re-used, a copy is made and updated.

`indices` is an integer tensor containing indices into a new tensor of shape `shape`. The last dimension of `indices` can be at most the rank of `shape`:

indices.shape[-1] <= shape.rank

The last dimension of `indices` corresponds to indices into elements (if `indices.shape[-1] = shape.rank`) or slices (if `indices.shape[-1] < shape.rank`) along dimension `indices.shape[-1]` of `shape`. `updates` is a tensor with shape

indices.shape[:-1] + shape[indices.shape[-1]:]

The simplest form of tensor_scatter_add is to add individual elements to a tensor by index. For example, say we want to add 4 elements in a rank-1 tensor with 8 elements.

In Python, this scatter add operation would look like this:

```python

indices = tf.constant([[4], [3], [1], [7]])
updates = tf.constant([9, 10, 11, 12])
tensor = tf.ones([8], dtype=tf.int32)
updated = tf.tensor_scatter_add(tensor, indices, updates)
with tf.Session() as sess:
  print(sess.run(scatter))

```

The resulting tensor would look like this:

[1, 12, 1, 11, 10, 1, 1, 13]

We can also, insert entire slices of a higher rank tensor all at once. For example, if we wanted to insert two slices in the first dimension of a rank-3 tensor with two matrices of new values.

In Python, this scatter add operation would look like this:

```python

indices = tf.constant([[0], [2]])
updates = tf.constant([[[5, 5, 5, 5], [6, 6, 6, 6],
                        [7, 7, 7, 7], [8, 8, 8, 8]],
                       [[5, 5, 5, 5], [6, 6, 6, 6],
                        [7, 7, 7, 7], [8, 8, 8, 8]]])
tensor = tf.ones([4, 4, 4])
updated = tf.tensor_scatter_add(tensor, indices, updates)
with tf.Session() as sess:
  print(sess.run(scatter))

```

The resulting tensor would look like this:

[[[6, 6, 6, 6], [7, 7, 7, 7], [8, 8, 8, 8], [9, 9, 9, 9]],
 [[1, 1, 1, 1], [1, 1, 1, 1], [1, 1, 1, 1], [1, 1, 1, 1]],
 [[6, 6, 6, 6], [7, 7, 7, 7], [8, 8, 8, 8], [9, 9, 9, 9]],
 [[1, 1, 1, 1], [1, 1, 1, 1], [1, 1, 1, 1], [1, 1, 1, 1]]]

Note that on CPU, if an out of bound index is found, an error is returned. On GPU, if an out of bound index is found, the index is ignored.

Arguments:

tensor: Tensor to copy/update.
indices: Index tensor.
updates: Updates to scatter into output.

Returns A new tensor copied from tensor and updates added according to the indices.

func TensorScatterSub ¶ added in v1.12.1

func TensorScatterSub(scope *Scope, tensor tf.Output, indices tf.Output, updates tf.Output) (output tf.Output)

Subtracts sparse `updates` from an existing tensor according to `indices`.

This operation creates a new tensor by subtracting sparse `updates` from the passed in `tensor`. This operation is very similar to `tf.scatter_nd_sub`, except that the updates are subtracted from an existing tensor (as opposed to a variable). If the memory for the existing tensor cannot be re-used, a copy is made and updated.

`indices` is an integer tensor containing indices into a new tensor of shape `shape`. The last dimension of `indices` can be at most the rank of `shape`:

indices.shape[-1] <= shape.rank

The last dimension of `indices` corresponds to indices into elements (if `indices.shape[-1] = shape.rank`) or slices (if `indices.shape[-1] < shape.rank`) along dimension `indices.shape[-1]` of `shape`. `updates` is a tensor with shape

indices.shape[:-1] + shape[indices.shape[-1]:]

The simplest form of tensor_scatter_sub is to subtract individual elements from a tensor by index. For example, say we want to insert 4 scattered elements in a rank-1 tensor with 8 elements.

In Python, this scatter subtract operation would look like this:

```python

indices = tf.constant([[4], [3], [1], [7]])
updates = tf.constant([9, 10, 11, 12])
tensor = tf.ones([8], dtype=tf.int32)
updated = tf.tensor_scatter_sub(tensor, indices, updates)
with tf.Session() as sess:
  print(sess.run(scatter))

```

The resulting tensor would look like this:

[1, -10, 1, -9, -8, 1, 1, -11]

We can also, insert entire slices of a higher rank tensor all at once. For example, if we wanted to insert two slices in the first dimension of a rank-3 tensor with two matrices of new values.

In Python, this scatter add operation would look like this:

```python

indices = tf.constant([[0], [2]])
updates = tf.constant([[[5, 5, 5, 5], [6, 6, 6, 6],
                        [7, 7, 7, 7], [8, 8, 8, 8]],
                       [[5, 5, 5, 5], [6, 6, 6, 6],
                        [7, 7, 7, 7], [8, 8, 8, 8]]])
tensor = tf.ones([4, 4, 4])
updated = tf.tensor_scatter_sub(tensor, indices, updates)
with tf.Session() as sess:
  print(sess.run(scatter))

```

The resulting tensor would look like this:

[[[-4, -4, -4, -4], [-5, -5, -5, -5], [-6, -6, -6, -6], [-7, -7, -7, -7]],
 [[1, 1, 1, 1], [1, 1, 1, 1], [1, 1, 1, 1], [1, 1, 1, 1]],
 [[-4, -4, -4, -4], [-5, -5, -5, -5], [-6, -6, -6, -6], [-7, -7, -7, -7]],
 [[1, 1, 1, 1], [1, 1, 1, 1], [1, 1, 1, 1], [1, 1, 1, 1]]]

Note that on CPU, if an out of bound index is found, an error is returned. On GPU, if an out of bound index is found, the index is ignored.

Arguments:

tensor: Tensor to copy/update.
indices: Index tensor.
updates: Updates to scatter into output.

Returns A new tensor copied from tensor and updates subtracted according to the indices.

func TensorScatterUpdate ¶ added in v1.12.1

func TensorScatterUpdate(scope *Scope, tensor tf.Output, indices tf.Output, updates tf.Output) (output tf.Output)

Scatter `updates` into an existing tensor according to `indices`.

This operation creates a new tensor by applying sparse `updates` to the passed in `tensor`. This operation is very similar to `tf.scatter_nd`, except that the updates are scattered onto an existing tensor (as opposed to a zero-tensor). If the memory for the existing tensor cannot be re-used, a copy is made and updated.

If `indices` contains duplicates, then their updates are accumulated (summed).

**WARNING**: The order in which updates are applied is nondeterministic, so the output will be nondeterministic if `indices` contains duplicates -- because of some numerical approximation issues, numbers summed in different order may yield different results.

`indices` is an integer tensor containing indices into a new tensor of shape `shape`. The last dimension of `indices` can be at most the rank of `shape`:

indices.shape[-1] <= shape.rank

The last dimension of `indices` corresponds to indices into elements (if `indices.shape[-1] = shape.rank`) or slices (if `indices.shape[-1] < shape.rank`) along dimension `indices.shape[-1]` of `shape`. `updates` is a tensor with shape

indices.shape[:-1] + shape[indices.shape[-1]:]

The simplest form of scatter is to insert individual elements in a tensor by index. For example, say we want to insert 4 scattered elements in a rank-1 tensor with 8 elements.

In Python, this scatter operation would look like this:

```python

indices = tf.constant([[4], [3], [1], [7]])
updates = tf.constant([9, 10, 11, 12])
tensor = tf.ones([8], dtype=tf.int32)
updated = tf.tensor_scatter_update(tensor, indices, updates)
with tf.Session() as sess:
  print(sess.run(scatter))

```

The resulting tensor would look like this:

[1, 11, 1, 10, 9, 1, 1, 12]

We can also, insert entire slices of a higher rank tensor all at once. For example, if we wanted to insert two slices in the first dimension of a rank-3 tensor with two matrices of new values.

In Python, this scatter operation would look like this:

```python

indices = tf.constant([[0], [2]])
updates = tf.constant([[[5, 5, 5, 5], [6, 6, 6, 6],
                        [7, 7, 7, 7], [8, 8, 8, 8]],
                       [[5, 5, 5, 5], [6, 6, 6, 6],
                        [7, 7, 7, 7], [8, 8, 8, 8]]])
tensor = tf.ones([4, 4, 4])
updated = tf.tensor_scatter_update(tensor, indices, updates)
with tf.Session() as sess:
  print(sess.run(scatter))

```

The resulting tensor would look like this:

[[[5, 5, 5, 5], [6, 6, 6, 6], [7, 7, 7, 7], [8, 8, 8, 8]],
 [[1, 1, 1, 1], [1, 1, 1, 1], [1, 1, 1, 1], [1, 1, 1, 1]],
 [[5, 5, 5, 5], [6, 6, 6, 6], [7, 7, 7, 7], [8, 8, 8, 8]],
 [[1, 1, 1, 1], [1, 1, 1, 1], [1, 1, 1, 1], [1, 1, 1, 1]]]

Note that on CPU, if an out of bound index is found, an error is returned. On GPU, if an out of bound index is found, the index is ignored.

Arguments:

tensor: Tensor to copy/update.
indices: Index tensor.
updates: Updates to scatter into output.

Returns A new tensor with the given shape and updates applied according to the indices.

func TensorSliceDataset ¶ added in v1.2.0

func TensorSliceDataset(scope *Scope, components []tf.Output, output_shapes []tf.Shape) (handle tf.Output)

Creates a dataset that emits each dim-0 slice of `components` once.

func TensorStridedSliceUpdate ¶ added in v1.12.1

func TensorStridedSliceUpdate(scope *Scope, input tf.Output, begin tf.Output, end tf.Output, strides tf.Output, value tf.Output, optional ...TensorStridedSliceUpdateAttr) (output tf.Output)

Assign `value` to the sliced l-value reference of `input`.

The values of `value` are assigned to the positions in the tensor `input` that are selected by the slice parameters. The slice parameters `begin` `end` `strides` etc. work exactly as in `StridedSlice`.

NOTE this op currently does not support broadcasting and so `value`'s shape must be exactly the shape produced by the slice of `input`.

func TensorSummary ¶ added in v1.1.0

func TensorSummary(scope *Scope, tensor tf.Output, optional ...TensorSummaryAttr) (summary tf.Output)

Outputs a `Summary` protocol buffer with a tensor.

This op is being phased out in favor of TensorSummaryV2, which lets callers pass a tag as well as a serialized SummaryMetadata proto string that contains plugin-specific data. We will keep this op to maintain backwards compatibility.

Arguments:

tensor: A tensor to serialize.

func TensorSummaryV2 ¶ added in v1.3.0

func TensorSummaryV2(scope *Scope, tag tf.Output, tensor tf.Output, serialized_summary_metadata tf.Output) (summary tf.Output)

Outputs a `Summary` protocol buffer with a tensor and per-plugin data.

Arguments:

tag: A string attached to this summary. Used for organization in TensorBoard.
tensor: A tensor to serialize.
serialized_summary_metadata: A serialized SummaryMetadata proto. Contains plugin

data.

func TextLineDataset ¶ added in v1.2.0

func TextLineDataset(scope *Scope, filenames tf.Output, compression_type tf.Output, buffer_size tf.Output) (handle tf.Output)

Creates a dataset that emits the lines of one or more text files.

Arguments:

filenames: A scalar or a vector containing the name(s) of the file(s) to be

read.

compression_type: A scalar containing either (i) the empty string (no

compression), (ii) "ZLIB", or (iii) "GZIP".

func TextLineReaderV2 ¶ added in v1.1.0

func TextLineReaderV2(scope *Scope, optional ...TextLineReaderV2Attr) (reader_handle tf.Output)

Returns The handle to reference the Reader.

func ThreadUnsafeUnigramCandidateSampler ¶ added in v1.1.0

func ThreadUnsafeUnigramCandidateSampler(scope *Scope, true_classes tf.Output, num_true int64, num_sampled int64, unique bool, range_max int64, optional ...ThreadUnsafeUnigramCandidateSamplerAttr) (sampled_candidates tf.Output, true_expected_count tf.Output, sampled_expected_count tf.Output)

Generates labels for candidate sampling with a learned unigram distribution.

See explanations of candidate sampling and the data formats at go/candidate-sampling.

For each batch, this op picks a single set of sampled candidate labels.

The advantages of sampling candidates per-batch are simplicity and the possibility of efficient dense matrix multiplication. The disadvantage is that the sampled candidates must be chosen independently of the context and of the true labels.

Arguments:

true_classes: A batch_size * num_true matrix, in which each row contains the

IDs of the num_true target_classes in the corresponding original label.

num_true: Number of true labels per context.
num_sampled: Number of candidates to randomly sample.
unique: If unique is true, we sample with rejection, so that all sampled

candidates in a batch are unique. This requires some approximation to estimate the post-rejection sampling probabilities.

range_max: The sampler will sample integers from the interval [0, range_max).

Returns A vector of length num_sampled, in which each element is the ID of a sampled candidate.A batch_size * num_true matrix, representing the number of times each candidate is expected to occur in a batch of sampled candidates. If unique=true, then this is a probability.A vector of length num_sampled, for each sampled candidate representing the number of times the candidate is expected to occur in a batch of sampled candidates. If unique=true, then this is a probability.

func Tile ¶ added in v1.1.0

func Tile(scope *Scope, input tf.Output, multiples tf.Output) (output tf.Output)

Constructs a tensor by tiling a given tensor.

This operation creates a new tensor by replicating `input` `multiples` times. The output tensor's i'th dimension has `input.dims(i) * multiples[i]` elements, and the values of `input` are replicated `multiples[i]` times along the 'i'th dimension. For example, tiling `[a b c d]` by `[2]` produces `[a b c d a b c d]`.

Arguments:

input: 1-D or higher.
multiples: 1-D. Length must be the same as the number of dimensions in `input`

func TileGrad ¶ added in v1.1.0

func TileGrad(scope *Scope, input tf.Output, multiples tf.Output) (output tf.Output)

Returns the gradient of `Tile`.

DEPRECATED at GraphDef version 3: TileGrad has been replaced with reduce_sum

Since `Tile` takes an input and repeats the input `multiples` times along each dimension, `TileGrad` takes in `multiples` and aggregates each repeated tile of `input` into `output`.

func Timestamp ¶ added in v1.9.0

func Timestamp(scope *Scope) (ts tf.Output)

Provides the time since epoch in seconds.

Returns the timestamp as a `float64` for seconds since the Unix epoch.

Note: the timestamp is computed when the op is executed, not when it is added to the graph.

func TopK ¶ added in v1.1.0

func TopK(scope *Scope, input tf.Output, k int64, optional ...TopKAttr) (values tf.Output, indices tf.Output)

Finds values and indices of the `k` largest elements for the last dimension.

DEPRECATED at GraphDef version 7: Use TopKV2 instead

If the input is a vector (rank-1), finds the `k` largest entries in the vector and outputs their values and indices as vectors. Thus `values[j]` is the `j`-th largest entry in `input`, and its index is `indices[j]`.

For matrices (resp. higher rank input), computes the top `k` entries in each row (resp. vector along the last dimension). Thus,

values.shape = indices.shape = input.shape[:-1] + [k]

If two elements are equal, the lower-index element appears first.

If `k` varies dynamically, use `TopKV2` below.

Arguments:

input: 1-D or higher with last dimension at least `k`.
k: Number of top elements to look for along the last dimension (along each

row for matrices).

Returns The `k` largest elements along each last dimensional slice.The indices of `values` within the last dimension of `input`.

func TopKV2 ¶ added in v1.1.0

func TopKV2(scope *Scope, input tf.Output, k tf.Output, optional ...TopKV2Attr) (values tf.Output, indices tf.Output)

Finds values and indices of the `k` largest elements for the last dimension.

If the input is a vector (rank-1), finds the `k` largest entries in the vector and outputs their values and indices as vectors. Thus `values[j]` is the `j`-th largest entry in `input`, and its index is `indices[j]`.

For matrices (resp. higher rank input), computes the top `k` entries in each row (resp. vector along the last dimension). Thus,

values.shape = indices.shape = input.shape[:-1] + [k]

If two elements are equal, the lower-index element appears first.

Arguments:

input: 1-D or higher with last dimension at least `k`.
k: 0-D.  Number of top elements to look for along the last dimension (along each

row for matrices).

Returns The `k` largest elements along each last dimensional slice.The indices of `values` within the last dimension of `input`.

func Transpose ¶ added in v1.1.0

func Transpose(scope *Scope, x tf.Output, perm tf.Output) (y tf.Output)

Shuffle dimensions of x according to a permutation.

The output `y` has the same rank as `x`. The shapes of `x` and `y` satisfy:

`y.shape[i] == x.shape[perm[i]] for i in [0, 1, ..., rank(x) - 1]`

func TridiagonalMatMul ¶ added in v1.14.0

func TridiagonalMatMul(scope *Scope, superdiag tf.Output, maindiag tf.Output, subdiag tf.Output, rhs tf.Output) (output tf.Output)

Calculate product with tridiagonal matrix.

Calculates product of two matrices, where left matrix is a tridiagonal matrix.

Arguments:

superdiag: Tensor of shape `[..., 1, M]`, representing superdiagonals of

tri-diagonal matrices to the left of multiplication. Last element is ingored.

func TridiagonalSolve ¶ added in v1.12.1

func TridiagonalSolve(scope *Scope, diagonals tf.Output, rhs tf.Output, optional ...TridiagonalSolveAttr) (output tf.Output)

Solves tridiagonal systems of equations.

Solves tridiagonal systems of equations.
Supports batch dimensions and multiple right-hand sides per each left-hand
side.
On CPU, solution is computed via Gaussian elimination with or without partial
pivoting, depending on `partial_pivoting` attribute. On GPU, Nvidia's cuSPARSE
library is used: https://docs.nvidia.com/cuda/cusparse/index.html#gtsv

Arguments:

diagonals: Tensor of shape `[..., 3, M]` whose innermost 2 dimensions represent the

tridiagonal matrices with three rows being the superdiagonal, diagonals, and subdiagonals, in order. The last element of the superdiagonal and the first element of the subdiagonal is ignored.

rhs: Tensor of shape `[..., M, K]`, representing K right-hand sides per each

left-hand side.

Returns Tensor of shape `[..., M, K]` containing the solutions

func TruncateDiv ¶ added in v1.1.0

func TruncateDiv(scope *Scope, x tf.Output, y tf.Output) (z tf.Output)

Returns x / y element-wise for integer types.

Truncation designates that negative numbers will round fractional quantities toward zero. I.e. -7 / 5 = -1. This matches C semantics but it is different than Python semantics. See `FloorDiv` for a division function that matches Python Semantics.

*NOTE*: `TruncateDiv` supports broadcasting. More about broadcasting [here](http://docs.scipy.org/doc/numpy/user/basics.broadcasting.html)

func TruncateMod ¶ added in v1.1.0

func TruncateMod(scope *Scope, x tf.Output, y tf.Output) (z tf.Output)

Returns element-wise remainder of division. This emulates C semantics in that

the result here is consistent with a truncating divide. E.g. `truncate(x / y) * y + truncate_mod(x, y) = x`.

*NOTE*: `TruncateMod` supports broadcasting. More about broadcasting [here](http://docs.scipy.org/doc/numpy/user/basics.broadcasting.html)

func TruncatedNormal ¶ added in v1.1.0

func TruncatedNormal(scope *Scope, shape tf.Output, dtype tf.DataType, optional ...TruncatedNormalAttr) (output tf.Output)

Outputs random values from a truncated normal distribution.

The generated values follow a normal distribution with mean 0 and standard deviation 1, except that values whose magnitude is more than 2 standard deviations from the mean are dropped and re-picked.

Arguments:

shape: The shape of the output tensor.
dtype: The type of the output.

Returns A tensor of the specified shape filled with random truncated normal values.

func TryRpc ¶ added in v1.9.0

func TryRpc(scope *Scope, address tf.Output, method tf.Output, request tf.Output, optional ...TryRpcAttr) (response tf.Output, status_code tf.Output, status_message tf.Output)

Perform batches of RPC requests.

This op asynchronously performs either a single RPC request, or a batch of requests. RPC requests are defined by three main parameters:

`address` (the host+port or BNS address of the request)
`method` (the method name for the request)
`request` (the serialized proto string, or vector of strings, of the RPC request argument).

For example, if you have an RPC service running on port localhost:2345, and its interface is configured with the following proto declaration:

```

service MyService {
  rpc MyMethod(MyRequestProto) returns (MyResponseProto) {
  }
};

```

then call this op with arguments:

``` address = "localhost:2345" method = "MyService/MyMethod" ```

The `request` tensor is a string tensor representing serialized `MyRequestProto` strings; and the output string tensor `response` will have the same shape and contain (upon successful completion) corresponding serialized `MyResponseProto` strings.

For example, to send a single, empty, `MyRequestProto`, call this op with `request = ""`. To send 5 **parallel** empty requests, call this op with `request = ["", "", "", "", ""]`.

More generally, one can create a batch of `MyRequestProto` serialized protos from regular batched tensors using the `encode_proto` op, and convert the response `MyResponseProto` serialized protos to batched tensors using the `decode_proto` op.

**NOTE** Working with serialized proto strings is faster than instantiating actual proto objects in memory, so no performance degradation is expected compared to writing custom kernels for this workflow.

Unlike the standard `Rpc` op, if the connection fails or the remote worker returns an error status, this op does **not** reraise the exception. Instead, the `status_code` and `status_message` entry for the corresponding RPC call is set with the error returned from the RPC call. The `response` tensor will contain valid response values for those minibatch entries whose RPCs did not fail; the rest of the entries will have empty strings.

Arguments:

address: `0-D` or `1-D`.  The address (i.e. host_name:port) of the RPC server.

If this tensor has more than 1 element, then multiple parallel rpc requests are sent. This argument broadcasts with `method` and `request`.

method: `0-D` or `1-D`.  The method address on the RPC server.

If this tensor has more than 1 element, then multiple parallel rpc requests are sent. This argument broadcasts with `address` and `request`.

request: `0-D` or `1-D`.  Serialized proto strings: the rpc request argument.

If this tensor has more than 1 element, then multiple parallel rpc requests are sent. This argument broadcasts with `address` and `method`.

Returns Same shape as `request`. Serialized proto strings: the rpc responses.Same shape as `request`. Values correspond to tensorflow Status enum codes.Same shape as `request`. Values correspond to Status messages returned from the RPC calls.

func Unbatch ¶ added in v1.9.0

func Unbatch(scope *Scope, batched_tensor tf.Output, batch_index tf.Output, id tf.Output, timeout_micros int64, optional ...UnbatchAttr) (unbatched_tensor tf.Output)

Reverses the operation of Batch for a single output Tensor.

An instance of Unbatch either receives an empty batched_tensor, in which case it asynchronously waits until the values become available from a concurrently running instance of Unbatch with the same container and shared_name, or receives a non-empty batched_tensor in which case it finalizes all other concurrently running instances and outputs its own element from the batch.

batched_tensor: The possibly transformed output of Batch. The size of the first

dimension should remain unchanged by the transformations for the operation to
work.

batch_index: The matching batch_index obtained from Batch. id: The id scalar emitted by Batch. unbatched_tensor: The Tensor corresponding to this execution. timeout_micros: Maximum amount of time (in microseconds) to wait to receive the

batched input tensor associated with a given invocation of the op.

container: Container to control resource sharing. shared_name: Instances of Unbatch with the same container and shared_name are

assumed to possibly belong to the same batch. If left empty, the op name will
be used as the shared name.

func UnbatchGrad ¶ added in v1.9.0

func UnbatchGrad(scope *Scope, original_input tf.Output, batch_index tf.Output, grad tf.Output, id tf.Output, optional ...UnbatchGradAttr) (batched_grad tf.Output)

Gradient of Unbatch.

Acts like Batch but using the given batch_index index of batching things as they become available. This ensures that the gradients are propagated back in the same session which did the forward pass.

original_input: The input to the Unbatch operation this is the gradient of. batch_index: The batch_index given to the Unbatch operation this is the gradient of. grad: The downstream gradient. id: The id scalar emitted by Batch. batched_grad: The return value, either an empty tensor or the batched gradient. container: Container to control resource sharing. shared_name: Instances of UnbatchGrad with the same container and shared_name

are assumed to possibly belong to the same batch. If left empty, the op name
will be used as the shared name.

func UnicodeDecode ¶ added in v1.12.1

func UnicodeDecode(scope *Scope, input tf.Output, input_encoding string, optional ...UnicodeDecodeAttr) (row_splits tf.Output, char_values tf.Output)

Decodes each string in `input` into a sequence of Unicode code points.

The character codepoints for all strings are returned using a single vector `char_values`, with strings expanded to characters in row-major order.

The `row_splits` tensor indicates where the codepoints for each input string begin and end within the `char_values` tensor. In particular, the values for the `i`th string (in row-major order) are stored in the slice `[row_splits[i]:row_splits[i+1]]`. Thus:

`char_values[row_splits[i]+j]` is the Unicode codepoint for the `j`th character in the `i`th string (in row-major order).
`row_splits[i+1] - row_splits[i]` is the number of characters in the `i`th string (in row-major order).

Arguments:

input: The text to be decoded. Can have any shape. Note that the output is flattened

to a vector of char values.

input_encoding: Text encoding of the input strings. This is any of the encodings supported

by ICU ucnv algorithmic converters. Examples: `"UTF-16", "US ASCII", "UTF-8"`.

func UnicodeDecodeWithOffsets ¶ added in v1.12.1

func UnicodeDecodeWithOffsets(scope *Scope, input tf.Output, input_encoding string, optional ...UnicodeDecodeWithOffsetsAttr) (row_splits tf.Output, char_values tf.Output, char_to_byte_starts tf.Output)

Decodes each string in `input` into a sequence of Unicode code points.

The character codepoints for all strings are returned using a single vector `char_values`, with strings expanded to characters in row-major order. Similarly, the character start byte offsets are returned using a single vector `char_to_byte_starts`, with strings expanded in row-major order.

The `row_splits` tensor indicates where the codepoints and start offsets for each input string begin and end within the `char_values` and `char_to_byte_starts` tensors. In particular, the values for the `i`th string (in row-major order) are stored in the slice `[row_splits[i]:row_splits[i+1]]`. Thus:

`char_values[row_splits[i]+j]` is the Unicode codepoint for the `j`th character in the `i`th string (in row-major order).
`char_to_bytes_starts[row_splits[i]+j]` is the start byte offset for the `j`th character in the `i`th string (in row-major order).
`row_splits[i+1] - row_splits[i]` is the number of characters in the `i`th string (in row-major order).

Arguments:

input: The text to be decoded. Can have any shape. Note that the output is flattened

to a vector of char values.

input_encoding: Text encoding of the input strings. This is any of the encodings supported

by ICU ucnv algorithmic converters. Examples: `"UTF-16", "US ASCII", "UTF-8"`.

Returns A 1D int32 tensor containing the row splits.A 1D int32 Tensor containing the decoded codepoints.A 1D int32 Tensor containing the byte index in the input string where each character in `char_values` starts.

func UnicodeEncode ¶ added in v1.12.1

func UnicodeEncode(scope *Scope, input_values tf.Output, input_splits tf.Output, output_encoding string, optional ...UnicodeEncodeAttr) (output tf.Output)

Encode a tensor of ints into unicode strings.

Returns a vector of strings, where `output[i]` is constructed by encoding the Unicode codepoints in `input_values[input_splits[i]:input_splits[i+1]]` using `output_encoding`.

---

Example:

``` input_values = [72, 101, 108, 108, 111, 87, 111, 114, 108, 100] input_splits = [0, 5, 10] output_encoding = 'UTF-8'

output = ['Hello', 'World'] ```

Arguments:

input_values: A 1D tensor containing the unicode codepoints that should be encoded.
input_splits: A 1D tensor specifying how the unicode codepoints should be split into strings.

In particular, `output[i]` is constructed by encoding the codepoints in the slice `input_values[input_splits[i]:input_splits[i+1]]`.

output_encoding: Unicode encoding of the output strings. Valid encodings are: `"UTF-8",

"UTF-16-BE", and "UTF-32-BE"`.

Returns The 1-D Tensor of strings encoded from the provided unicode codepoints.

func UnicodeScript ¶ added in v1.12.1

func UnicodeScript(scope *Scope, input tf.Output) (output tf.Output)

Determine the script codes of a given tensor of Unicode integer code points.

This operation converts Unicode code points to script codes corresponding to each code point. Script codes correspond to International Components for Unicode (ICU) UScriptCode values. See http://icu-project.org/apiref/icu4c/uscript_8h.html. Returns -1 (USCRIPT_INVALID_CODE) for invalid codepoints. Output shape will match input shape.

Arguments:

input: A Tensor of int32 Unicode code points.

Returns A Tensor of int32 script codes corresponding to each input code point.

func UnicodeTranscode ¶ added in v1.12.1

func UnicodeTranscode(scope *Scope, input tf.Output, input_encoding string, output_encoding string, optional ...UnicodeTranscodeAttr) (output tf.Output)

Transcode the input text from a source encoding to a destination encoding.

The input is a string tensor of any shape. The output is a string tensor of the same shape containing the transcoded strings. Output strings are always valid unicode. If the input contains invalid encoding positions, the `errors` attribute sets the policy for how to deal with them. If the default error-handling policy is used, invalid formatting will be substituted in the output by the `replacement_char`. If the errors policy is to `ignore`, any invalid encoding positions in the input are skipped and not included in the output. If it set to `strict` then any invalid formatting will result in an InvalidArgument error.

This operation can be used with `output_encoding = input_encoding` to enforce correct formatting for inputs even if they are already in the desired encoding.

If the input is prefixed by a Byte Order Mark needed to determine encoding (e.g. if the encoding is UTF-16 and the BOM indicates big-endian), then that BOM will be consumed and not emitted into the output. If the input encoding is marked with an explicit endianness (e.g. UTF-16-BE), then the BOM is interpreted as a non-breaking-space and is preserved in the output (including always for UTF-8).

The end result is that if the input is marked as an explicit endianness the transcoding is faithful to all codepoints in the source. If it is not marked with an explicit endianness, the BOM is not considered part of the string itself but as metadata, and so is not preserved in the output.

Arguments:

input: The text to be processed. Can have any shape.
input_encoding: Text encoding of the input strings. This is any of the encodings supported

by ICU ucnv algorithmic converters. Examples: `"UTF-16", "US ASCII", "UTF-8"`.

output_encoding: The unicode encoding to use in the output. Must be one of

`"UTF-8", "UTF-16-BE", "UTF-32-BE"`. Multi-byte encodings will be big-endian.

Returns A string tensor containing unicode text encoded using `output_encoding`.

Generates labels for candidate sampling with a uniform distribution.

See explanations of candidate sampling and the data formats at go/candidate-sampling.

For each batch, this op picks a single set of sampled candidate labels.

The advantages of sampling candidates per-batch are simplicity and the possibility of efficient dense matrix multiplication. The disadvantage is that the sampled candidates must be chosen independently of the context and of the true labels.

Arguments:

true_classes: A batch_size * num_true matrix, in which each row contains the

IDs of the num_true target_classes in the corresponding original label.

num_true: Number of true labels per context.

unique: If unique is true, we sample with rejection, so that all sampled

candidates in a batch are unique. This requires some approximation to estimate the post-rejection sampling probabilities.

range_max: The sampler will sample integers from the interval [0, range_max).

Returns A vector of length num_sampled, in which each element is the ID of a sampled candidate.A batch_size * num_true matrix, representing the number of times each candidate is expected to occur in a batch of sampled candidates. If unique=true, then this is a probability.A vector of length num_sampled, for each sampled candidate representing the number of times the candidate is expected to occur in a batch of sampled candidates. If unique=true, then this is a probability.

Unpacks `num` tensors from `value` by chipping it along the `axis` dimension. For example, given a tensor of shape `(A, B, C, D)`;

If `axis == 0` then the i'th tensor in `output` is the slice `value[i, :, :, :]`

and each tensor in `output` will have shape `(B, C, D)`. (Note that the

func UnsortedSegmentMax ¶ added in v1.1.0

func UnsortedSegmentMax(scope *Scope, data tf.Output, segment_ids tf.Output, num_segments tf.Output) (output tf.Output)

Computes the maximum along segments of a tensor.

Read [the section on segmentation](https://tensorflow.org/api_docs/python/tf/math#Segmentation) for an explanation of segments.

This operator is similar to the unsorted segment sum operator found [(here)](../../../api_docs/python/math_ops.md#UnsortedSegmentSum). Instead of computing the sum over segments, it computes the maximum such that:

\$output_i = \max_{j...} data[j...]\$ where max is over tuples `j...` such that `segment_ids[j...] == i`.

If the maximum is empty for a given segment ID `i`, it outputs the smallest possible value for the specific numeric type, `output[i] = numeric_limits<T>::lowest()`.

If the given segment ID `i` is negative, then the corresponding value is dropped, and will not be included in the result.

For example:

``` python c = tf.constant([[1,2,3,4], [5,6,7,8], [4,3,2,1]]) tf.unsorted_segment_max(c, tf.constant([0, 1, 0]), num_segments=2) # ==> [[ 4, 3, 3, 4], # [5, 6, 7, 8]] ```

func UnsortedSegmentMin(scope *Scope, data tf.Output, segment_ids tf.Output, num_segments tf.Output) (output tf.Output)

Computes the minimum along segments of a tensor.

Read [the section on segmentation](https://tensorflow.org/api_docs/python/tf/math#Segmentation) for an explanation of segments.

This operator is similar to the unsorted segment sum operator found [(here)](../../../api_docs/python/math_ops.md#UnsortedSegmentSum). Instead of computing the sum over segments, it computes the minimum such that:

\$output_i = \min_{j...} data_[j...]\$ where min is over tuples `j...` such that `segment_ids[j...] == i`.

If the minimum is empty for a given segment ID `i`, it outputs the largest possible value for the specific numeric type, `output[i] = numeric_limits<T>::max()`.

For example:

``` python c = tf.constant([[1,2,3,4], [5,6,7,8], [4,3,2,1]]) tf.unsorted_segment_min(c, tf.constant([0, 1, 0]), num_segments=2) # ==> [[ 1, 2, 2, 1], # [5, 6, 7, 8]] ```

If the given segment ID `i` is negative, then the corresponding value is dropped, and will not be included in the result.

Arguments:

segment_ids: A tensor whose shape is a prefix of `data.shape`.

Returns Has same shape as data, except for the first `segment_ids.rank` dimensions, which are replaced with a single dimension which has size `num_segments`.

func UnsortedSegmentProd ¶ added in v1.9.0

func UnsortedSegmentProd(scope *Scope, data tf.Output, segment_ids tf.Output, num_segments tf.Output) (output tf.Output)

Computes the product along segments of a tensor.

Read [the section on segmentation](https://tensorflow.org/api_docs/python/tf/math#Segmentation) for an explanation of segments.

This operator is similar to the unsorted segment sum operator found [(here)](../../../api_docs/python/math_ops.md#UnsortedSegmentSum). Instead of computing the sum over segments, it computes the product of all entries belonging to a segment such that:

\$output_i = \prod_{j...} data[j...]\$ where the product is over tuples `j...` such that `segment_ids[j...] == i`.

For example:

``` python c = tf.constant([[1,2,3,4], [5,6,7,8], [4,3,2,1]]) tf.unsorted_segment_prod(c, tf.constant([0, 1, 0]), num_segments=2) # ==> [[ 4, 6, 6, 4], # [5, 6, 7, 8]] ```

If there is no entry for a given segment ID `i`, it outputs 1.

If the given segment ID `i` is negative, then the corresponding value is dropped, and will not be included in the result.

Arguments:

segment_ids: A tensor whose shape is a prefix of `data.shape`.

Returns Has same shape as data, except for the first `segment_ids.rank` dimensions, which are replaced with a single dimension which has size `num_segments`.

func UnsortedSegmentSum ¶ added in v1.1.0

func UnsortedSegmentSum(scope *Scope, data tf.Output, segment_ids tf.Output, num_segments tf.Output) (output tf.Output)

Computes the sum along segments of a tensor.

Read [the section on segmentation](https://tensorflow.org/api_docs/python/tf/math#Segmentation) for an explanation of segments.

Computes a tensor such that \$output[i] = \sum_{j...} data[j...]\$ where the sum is over tuples `j...` such that `segment_ids[j...] == i`. Unlike `SegmentSum`, `segment_ids` need not be sorted and need not cover all values in the full range of valid values.

If the sum is empty for a given segment ID `i`, `output[i] = 0`. If the given segment ID `i` is negative, the value is dropped and will not be added to the sum of the segment.

`num_segments` should equal the number of distinct segment IDs.

``` python c = tf.constant([[1,2,3,4], [5,6,7,8], [4,3,2,1]]) tf.unsorted_segment_sum(c, tf.constant([0, 1, 0]), num_segments=2) # ==> [[ 5, 5, 5, 5], # [5, 6, 7, 8]] ```

Arguments:

segment_ids: A tensor whose shape is a prefix of `data.shape`.

Returns Has same shape as data, except for the first `segment_ids.rank` dimensions, which are replaced with a single dimension which has size `num_segments`.

func Unstage ¶ added in v1.1.0

func Unstage(scope *Scope, dtypes []tf.DataType, optional ...UnstageAttr) (values []tf.Output)

func UpperBound(scope *Scope, sorted_inputs tf.Output, values tf.Output, optional ...UpperBoundAttr) (output tf.Output)

Applies upper_bound(sorted_search_values, values) along each row.

Each set of rows with the same index in (sorted_inputs, values) is treated independently. The resulting row is the equivalent of calling `np.searchsorted(sorted_inputs, values, side='right')`.

The result is not a global index to the entire `Tensor`, but rather just the index in the last dimension.

A 2-D example:

sorted_sequence = [[0, 3, 9, 9, 10],
                   [1, 2, 3, 4, 5]]
values = [[2, 4, 9],
          [0, 2, 6]]

Example ¶

var (
	s  = NewScope()
	c1 = Const(s.SubScope("x"), int64(1))
	c2 = Const(s.SubScope("x"), int64(1))
)
if s.Err() != nil {
