  let description = [{
Broadcasting is the process of making arrays to have compatible shapes
for arithmetic operations. Two shapes are compatible if for each
dimension pair they are either equal or one of them is one. When trying
to broadcast a Tensor to a shape, it starts with the trailing dimensions,
and works its way forward.

For example,

>>> x = tf.constant([1, 2, 3])
>>> y = tf.broadcast_to(x, [3, 3])
>>> print(y)
tf.Tensor(
    [[1 2 3]
     [1 2 3]
     [1 2 3]], shape=(3, 3), dtype=int32)

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

When doing broadcasted operations such as multiplying a tensor
by a scalar, broadcasting (usually) confers some time or space
benefit, as the broadcasted tensor is never materialized.

However, `broadcast_to` does not carry with it any such benefits.
The newly-created tensor takes the full memory of the broadcasted
shape. (In a graph context, `broadcast_to` might be fused to
subsequent operation and then be optimized away, however.)

performs the following:

1. Flattens the filter to a 2-D matrix with shape
   `[filter_height * filter_width * in_channels, output_channels]`.
2. Extracts image patches from the input tensor to form a *virtual*
   tensor of shape `[batch, out_height, out_width,
   filter_height * filter_width * in_channels]`.
3. For each patch, right-multiplies the filter matrix and the image patch
   vector.

In detail, with the default NHWC format,

    output[b, i, j, k] =
        sum_{di, dj, q} input[b, strides[1] * i + di, strides[2] * j + dj, q] *
                        filter[di, dj, q, k]

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

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:

```
x =  [[[[1, 2, 3, 4],
       [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]],
      [ [11], [12], [15],  [16]]]]

Dequantize the 'input' tensor into a float or bfloat16 Tensor.
  }];

  let description = [{
[min_range, max_range] are scalar floats that specify the range for
the output. 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)
```

If the mode is `SCALED`, dequantization is performed by multiplying each
input value by a scaling_factor. (Thus an input of 0 always maps to 0.0).

The scaling_factor is determined from `min_range`, `max_range`, and
`narrow_range` in a way that is compatible with `QuantizeAndDequantize{V2|V3}`
and `QuantizeV2`, using the following algorithm:

```c++

  const int min_expected_T = std::numeric_limits<T>::min() +
    (narrow_range ? 1 : 0);
  const int max_expected_T = std::numeric_limits<T>::max();
  const float max_expected_T = std::numeric_limits<float>::max();

  const float scale_factor =
    (std::numeric_limits<T>::min() == 0) ? (max_range / max_expected_T)
                                         : std::max(min_range / min_expected_T,
                                                    max_range / max_expected_T);

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.
```

def TF_EinsumOp : TF_Op<"Einsum", [NoSideEffect]> {

Tensor contraction according to Einstein summation convention.
  }];

  let description = [{
Implements generalized Tensor contraction and reduction. Each input Tensor must
have a corresponding input subscript appearing in the comma-separated left-hand
side of the equation. The right-hand side of the equation consists of the
output subscript. The input subscripts and the output subscript should consist
of zero or more named axis labels and at most one ellipsis (`...`).

The named axis labels may be any single character other than those having
special meaning, namely `,.->`. The behavior of this Op is undefined if it
receives an ill-formatted equation; since the validation is done at
graph-building time, we omit format validation checks at runtime.

Note: This Op is *not* intended to be called by the user; instead users should
call `tf.einsum` directly. It is a hidden Op used by `tf.einsum`.

Operations are applied to the input(s) according to the following rules:

 (a) Generalized Diagonals: For input dimensions corresponding to axis labels
     appearing more than once in the same input subscript, we take the
     generalized (`k`-dimensional) diagonal.
     For example, in the equation `iii->i` with input shape `[3, 3, 3]`, the
     generalized diagonal would consist of `3` elements at indices `(0, 0, 0)`,
     `(1, 1, 1)` and `(2, 2, 2)` to create a Tensor of shape `[3]`.

 (b) Reduction: Axes corresponding to labels appearing only in one input
     subscript but not in the output subscript are summed over prior to Tensor
     contraction.
     For example, in the equation `ab,bc->b`, the axis labels `a` and `c` are
     the reduction axis labels.

 (c) Batch Dimensions: Axes corresponding to labels appearing in each of the
     input subscripts and also in the output subscript make up the batch
     dimensions in Tensor contraction. Unnamed axis labels corresponding to
     ellipsis (`...`) also correspond to batch dimensions.
     For example, for the equation denoting batch matrix multiplication,
     `bij,bjk->bik`, the axis label `b` corresponds to a batch dimension.

 (d) Contraction: In case of binary einsum, axes corresponding to labels
     appearing in two different inputs (and not in the output) are contracted
     against each other.
     Considering the batch matrix multiplication equation again
     (`bij,bjk->bik`), the contracted axis label is `j`.

 (e) Expand Diagonal: If the output subscripts contain repeated (explicit) axis
     labels, the opposite operation of (a) is applied. For example, in the
     equation `i->iii`, and input shape `[3]`, the output of shape `[3, 3, 3]`
     are all zeros, except for the (generalized) diagonal which is populated
     with values from the input.
     Note: This operation is not supported by `np.einsum` or `tf.einsum`; it is
     provided to enable computing the symbolic gradient of `tf.einsum`.

The output subscripts must contain only labels appearing in at least one of the
input subscripts. Furthermore, all dimensions mapping to the same axis label
must be equal.

Any of the input and output subscripts may contain at most a single ellipsis
(`...`). These ellipsis are mapped against dimensions not corresponding to any
named axis label. If two inputs contain ellipsis, then they are broadcasted
according to standard NumPy broadcasting
[rules](http://docs.scipy.org/doc/numpy/user/basics.broadcasting.html).

The broadcasted dimensions are placed in the corresponding location of the
ellipsis in the output subscript. If the broadcasted dimensions are non-empty
and the output subscripts do not contain ellipsis, then an InvalidArgument error
is raised.

@compatibility(numpy)
Similar to [`numpy.einsum`](https://docs.scipy.org/doc/numpy/reference/generated/numpy.einsum.html).

Comparison with `numpy.einsum`:

 * This Op only supports unary and binary forms of `numpy.einsum`.
 * This Op does not support implicit form. (i.e. equations without `->`).
 * This Op also supports repeated indices in the output subscript, which is not
   supported by `numpy.einsum`.

  `e` denotes Euler's number and is approximately equal to 2.718281.
  Output is positive for any real input.

  ```python
  x = tf.constant(2.0)
  tf.math.exp(x) ==> 7.389056

  x = tf.constant([2.0, 8.0])
  tf.math.exp(x) ==> array([7.389056, 2980.958], dtype=float32)
  ```

  For complex numbers, the exponential value is calculated as follows:

  ```
  e^(x+iy) = e^x * e^iy = e^x * (cos y + i sin y)
  ```

  Let's consider complex number 1+1j as an example.
  e^1 * (cos 1 + i sin 1) = 2.7182818284590 * (0.54030230586+0.8414709848j)

  ```python
  x = tf.constant(1 + 1j)
  tf.math.exp(x) ==> 1.4686939399158851+2.2873552871788423j

  let description = [{
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.

`indices` is a 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 `axis`
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.

Simple indexing into a matrix:

```python
    indices = [[0, 0], [1, 1]]
    params = [['a', 'b'], ['c', 'd']]
    output = ['a', 'd']
```

Slice indexing into a matrix:

```python
    indices = [[1], [0]]
    params = [['a', 'b'], ['c', 'd']]
    output = [['c', 'd'], ['a', 'b']]
```

Indexing into a 3-tensor:

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

Batched indexing into a matrix:

```python
    indices = [[[0, 0]], [[0, 1]]]
    params = [['a', 'b'], ['c', 'd']]
    output = [['a'], ['b']]
```

Batched slice indexing into a matrix:

```python

    params = [['a', 'b'], ['c', 'd']]
    output = [[['c', 'd']], [['a', 'b']]]

Batched indexing into a 3-tensor:

integer tensor `x`, which represents the indices of a zero-based array, and
swaps each value with its index position. In other words, for an output tensor
`y` and an input tensor `x`, this operation computes the following:

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

The values must include 0. There can be no duplicate values or negative values.

For example:

```
# tensor `x` is [3, 4, 0, 2, 1]
invert_permutation(x) ==> [2, 4, 3, 0, 1]

A one-shot iterator bundles the logic for defining the dataset and

pipelines to be defined without an additional initialization

One-shot iterators have the following limitations:

* They do not support parameterization: all logic for creating the underlying
  dataset must be bundled in the `dataset_factory` function.
* They are not resettable. Once a one-shot iterator reaches the end of its
  underlying dataset, subsequent "IteratorGetNext" operations on that
  iterator will always produce an `OutOfRange` error.

For greater flexibility, use "Iterator" and "MakeIterator" to define
an iterator using an arbitrary subgraph, which may capture tensors
(including fed values) as parameters, and which may be reset multiple
times by rerunning "MakeIterator".

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.

  let description = [{
This op simulates the precision loss from the quantized forward pass by:

1. Quantizing the tensor to fixed point numbers, which should match the target
   quantization method when it is used in inference.
2. 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 representable 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.

The `shape` must be 1-D and the operation returns a tensor with shape

def TF_ScatterNdOp : TF_Op<"ScatterNd", [NoSideEffect]> {

Scatters `updates` into a tensor of shape `shape` according to `indices`.
  }];

  let description = [{
Update the input tensor by scattering sparse `updates` according to individual values at the specified `indices`.
This op returns an `output` tensor with the `shape` you specify. This op is the
inverse of the `tf.gather_nd` operator which extracts values or slices from a
given tensor.

This operation is similar to `tf.tensor_scatter_add`, except that the tensor is
zero-initialized. Calling `tf.scatter_nd(indices, values, shape)`
is identical to calling
`tf.tensor_scatter_add(tf.zeros(shape, values.dtype), indices, values)`.

If `indices` contains duplicates, the duplicate `values` are accumulated
(summed).

**WARNING**: The order in which updates are applied is nondeterministic, so the
output will be nondeterministic if `indices` contains duplicates;
numbers summed in different order may yield different results because of some
numerical approximation issues.

`indices` is an integer 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 of 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 the scatter op is to insert individual elements in
a tensor by index. Consider an example where you want to insert 4 scattered
elements in a rank-1 tensor with 8 elements.

<div style="width:70%; margin:auto; margin-bottom:10px; margin-top:20px;">
<img style="width:100%" src="https://www.tensorflow.org/images/ScatterNd1.png" alt>
</div>

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)
    print(scatter)
```

The resulting tensor would look like this:

    [0, 11, 0, 10, 9, 0, 0, 12]

You can also insert entire slices of a higher rank tensor all at once. For
example, you can insert two slices in the first dimension of a rank-3 tensor
with two matrices of new values.

<img style="width:100%" src="https://www.tensorflow.org/images/ScatterNd2.png" alt>

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)
    print(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]],

This is a legacy version of the more general SpaceToBatchND.

Zero-pads and then rearranges (permutes) blocks of spatial data into batch.
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.

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,

  let description = [{
This operation divides "spatial" dimensions `[1, ..., M]` of the input into a
grid of blocks of shape `block_shape`, and interleaves these blocks with the
"batch" dimension (0) such that in the output, the spatial dimensions
`[1, ..., M]` correspond to the position within the grid, and the batch
dimension combines both the position within a spatial block and the original
batch position.  Prior to division into blocks, the spatial dimensions of the
input are optionally zero padded according to `paddings`. See below for a
precise description.

This operation is equivalent to the following steps:

1. 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

3. 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

4. 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],

def TF_SpaceToDepthOp : TF_Op<"SpaceToDepth", [NoSideEffect]> {
  let summary = "SpaceToDepth for tensors of type T.";

  let description = [{
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]]]]

    [0, 1]: a
    [0, 3]: b
    [2, 0]: c

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. For example, the softmax function
for a vector x can be written as

```python

  def softmax(x):
    numerator = tf.exp(x)
    denominator = tf.reduce_sum(numerator)
    return numerator / denominator
```

This however is susceptible to overflow if the values in x are large. An
alternative more stable way is to subtract the maximum of x from each of the
values.

```python

  def stable_softmax(x):
    z = x - tf.reduce_max(x)
    numerator = tf.exp(z)
    denominator = tf.reduce_sum(numerator)
    return numerator / denominator
```

However, when we backprop through the softmax to x, we dont want to backprop
through the `tf.reduce_max(x)` (if the max values are not unique then the
gradient could flow to the wrong input) calculation and treat that as a
constant. Therefore, we should write this out as

```python

  def stable_softmax(x):
    z = x - tf.stop_gradient(tf.reduce_max(x))
    numerator = tf.exp(z)
    denominator = tf.reduce_sum(numerator)
    return numerator / denominator
```

Some other 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.

def TF_StridedSliceOp : TF_Op<"StridedSlice", [NoSideEffect]> {
  let summary = "Return a strided slice from `input`.";

  let description = [{
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 = 1
```

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)`

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.

Adds sparse `updates` to an existing tensor according to `indices`.

This operation creates a new tensor by adding sparse `updates` to the passed

This operation is very similar to `tf.compat.v1.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
`tensor.shape`.  The last dimension of `indices` can be at most the rank of
`tensor.shape`:

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

The last dimension of `indices` corresponds to indices into elements
(if `indices.shape[-1] = tensor.shape.rank`) or slices
(if `indices.shape[-1] < tensor.shape.rank`) along dimension
`indices.shape[-1]` of `tensor.shape`.  `updates` is a tensor with shape

    indices.shape[:-1] + tensor.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_nd_add(tensor, indices, updates)
    print(updated)
```

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],dtype=tf.int32)
    updated = tf.tensor_scatter_nd_add(tensor, indices, updates)
    print(updated)
```

The resulting tensor would look like this:

     [[1, 1, 1, 1], [1, 1, 1, 1], [1, 1, 1, 1], [1, 1, 1, 1]]]

This operation creates a new tensor by applying sparse `updates` to the passed

This operation is very similar to `tf.scatter_nd`, except that the updates are

If `indices` contains duplicates, then we pick the last update for the index.

If an out of bound index is found on CPU, an error is returned.

**WARNING**: There are some GPU specific semantics for this operation.
- If an out of bound index is found, the index is ignored.
- The order in which updates are applied is nondeterministic, so the output
will be nondeterministic if `indices` contains duplicates.

`indices` is an integer tensor containing indices into a new tensor of shape
`shape`.

* `indices` must have at least 2 axes: `(num_updates, index_depth)`.
* The last axis of `indices` is how deep to index into `tensor` so  this index
  depth must be less than the rank of `tensor`: `indices.shape[-1] <= tensor.ndim`

if `indices.shape[-1] = tensor.rank` this Op indexes and updates scalar elements.
if `indices.shape[-1] < tensor.rank` it indexes and updates slices of the input
`tensor`.

Each `update` has a rank of `tensor.rank - indices.shape[-1]`.
The overall shape of `updates` is:

```
indices.shape[:-1] + tensor.shape[indices.shape[-1]:]
