def batch_to_space_nd(input, block_shape, crops, name=None):
  r"""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.

  Args:
    input: A `Tensor`.
      N-D with shape `input_shape = [batch] + spatial_shape + remaining_shape`,
      where spatial_shape has M dimensions.
    block_shape: A `Tensor`. Must be one of the following types: `int32`, `int64`.
      1-D with shape `[M]`, all values must be >= 1.
    crops: A `Tensor`. Must be one of the following types: `int32`, `int64`.
      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:

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

      2. 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]]

      3. 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]]

      4. 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]]

      Some examples:

      (1) For the following input of shape `[4, 1, 1, 1]`, `block_shape = [2, 2]`, and

  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 [...].

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

  Args:
    input: A `Tensor`. Must be one of the following types: `bfloat16`, `half`, `float32`, `float64`, `int64`, `int32`, `uint8`, `uint16`, `int8`, `int16`, `complex64`, `complex128`, `qint8`, `quint8`, `qint16`, `quint16`, `qint32`.

def depth_to_space(input, block_size, data_format="NHWC", name=None):
  r"""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:

  ```
  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]]]]

  ```

@tf_export('dequantize')
def dequantize(input, min_range, max_range, mode="MIN_COMBINED", name=None):
  r"""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
  ```

  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.

  Args:
    input: A `Tensor`.
    axis: A `Tensor`. Must be one of the following types: `int32`, `int64`.
      0-D (scalar). Specifies the dimension index at which to

def gather_nd(params, indices, name=None):
  r"""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[i0, ..., 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.

def quantize_and_dequantize_v2(input, input_min, input_max, signed_input=True, num_bits=8, range_given=False, name=None):
  r"""Quantizes then dequantizes a tensor.

  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 does 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.

  To perform this op, 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

  1. m = max(abs(input_min), abs(input_max)) if range_given is true,
  2. m = max(abs(min_elem(input)), abs(max_elem(input))) otherwise.

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

  Next, we choose our fixed-point quantization buckets, [min_fixed, max_fixed].
  If signed_input is true, this is

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

  Otherwise, if signed_input is false, the fixed-point range is

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

  From this we compute our scaling factor, s:

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

  Now we can quantize and dequantize the elements of our tensor.  An element e
  is transformed into e':

    e' = (e * s).round_to_nearest() / s.

  Note that we have a different number of buckets in the signed vs. unsigned
  cases.  For example, if num_bits == 8, we get 254 buckets in the signed case
  vs. 255 in the unsigned case.

  For example, suppose num_bits = 8 and m = 1.  Then

    [min_fixed, max_fixed] = [-127, 127], and
    s = (127 + 127) / 2 = 127.

  Given the vector {-1, -0.5, 0, 0.3}, this is quantized to
  {-127, -63, 0, 38}, and dequantized to {-1, -63.0/127, 0, 38.0/127}.

  Args:
    input: A `Tensor`. Must be one of the following types: `bfloat16`, `half`, `float32`, `float64`.
      Tensor to quantize and then dequantize.
    input_min: A `Tensor`. Must have the same type as `input`.
      If range_given, this is the min of the range, otherwise this input
      will be ignored.
    input_max: A `Tensor`. Must have the same type as `input`.
      If range_given, this is the max of the range, otherwise this input
      will be ignored.
    signed_input: An optional `bool`. Defaults to `True`.
      If the quantization is signed or unsigned.
    num_bits: An optional `int`. Defaults to `8`.
      The bitwidth of the quantization.
    range_given: An optional `bool`. Defaults to `False`.
      If the range is given or should be computed from the tensor.
    name: A name for the operation (optional).

def quantize_v2(input, min_range, max_range, T, mode="MIN_COMBINED", round_mode="HALF_AWAY_FROM_ZERO", name=None):
  r"""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.

  Args:
    input: A `Tensor` of type `float32`.
    min_range: A `Tensor` of type `float32`.
      The minimum scalar value possibly produced for the input.
    max_range: A `Tensor` of type `float32`.

  Given `tensor`, this operation returns a tensor that has the same values

  Given a `tensor`, and a `bool` tensor `dims` representing the dimensions

def scatter_nd(indices, updates, shape, name=None):
  r"""Scatter `updates` into a new (initially zero) tensor according to `indices`.

  Creates a new tensor by applying sparse `updates` to individual
  values or slices within a zero tensor 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.

  **WARNING**: 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`.  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.

  <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)
      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.

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

  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]],

      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]],

def scatter_nd_non_aliasing_add(input, indices, updates, name=None):
  r"""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.

  Args:
    input: A `Tensor`. Must be one of the following types: `float32`, `float64`, `int32`, `uint8`, `int16`, `int8`, `complex64`, `int64`, `qint8`, `quint8`, `qint32`, `bfloat16`, `uint16`, `complex128`, `half`, `uint32`, `uint64`.

  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.

    input: A `Tensor`. 4-D with shape `[batch, height, width, depth]`.
    paddings: A `Tensor`. Must be one of the following types: `int32`, `int64`.
      2-D tensor of non-negative integers with shape `[2, 2]`. It specifies
        the padding of the input with zeros across the spatial dimensions as follows:

            paddings = [[pad_top, pad_bottom], [pad_left, pad_right]]

        The effective spatial dimensions of the zero-padded input tensor will be:

            height_pad = pad_top + height + pad_bottom

          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:

def space_to_batch_nd(input, block_shape, paddings, name=None):
  r"""SpaceToBatch for N-D tensors of type T.

  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.

  Args:
    input: A `Tensor`.
      N-D with shape `input_shape = [batch] + spatial_shape + remaining_shape`,
      where spatial_shape has `M` dimensions.
    block_shape: A `Tensor`. Must be one of the following types: `int32`, `int64`.
      1-D with shape `[M]`, all values must be >= 1.
    paddings: A `Tensor`. Must be one of the following types: `int32`, `int64`.
      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:

      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],
            ...,
            padded_shape[M] / block_shape[M-1]] +
           remaining_shape

def space_to_depth(input, block_size, data_format="NHWC", name=None):
  r"""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]]]]
  ```

  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

def strided_slice(input, begin, end, strides, begin_mask=0, end_mask=0, ellipsis_mask=0, new_axis_mask=0, shrink_axis_mask=0, name=None):
  r"""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)`

  Args:
    input: A `Tensor`.
    begin: A `Tensor`. Must be one of the following types: `int32`, `int64`.
      `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: A `Tensor`. Must have the same type as `begin`.
      `end[i]` is like `begin` with the exception that `end_mask` is
      used to determine full ranges.
    strides: A `Tensor`. Must have the same type as `begin`.
      `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`
    begin_mask: An optional `int`. Defaults to `0`.
      a bitmask where a bit i being 1 means to ignore the begin
      value and instead use the largest interval possible. At runtime
      begin[i] will be replaced with `[0, n-1) if `stride[i] > 0` or
      `[-1, n-1]` if `stride[i] < 0`
    end_mask: An optional `int`. Defaults to `0`. analogous to `begin_mask`
    ellipsis_mask: An optional `int`. Defaults to `0`.
      a bitmask where bit `i` being 1 means the `i`th
      position is actually an ellipsis. One bit at most can be 1.
      If `ellipsis_mask == 0`, then an implicit ellipsis mask of `1 << (m+1)`
      is provided. This means that `foo[3:5] == foo[3:5, ...]`. An ellipsis
      implicitly creates as many range specifications as necessary to fully
      specify the sliced range for every dimension. For example for a 4-dimensional
      tensor `foo` the slice `foo[2, ..., 5:8]` implies `foo[2, :, :, 5:8]`.
    new_axis_mask: An optional `int`. Defaults to `0`.
      a bitmask where bit `i` being 1 means the `i`th
      specification creates a new shape 1 dimension. For example
      `foo[:4, tf.newaxis, :2]` would produce a shape `(4, 1, 2)` tensor.
    shrink_axis_mask: An optional `int`. Defaults to `0`.
      a bitmask where bit `i` implies that the `i`th
      specification should shrink the dimensionality. begin and end
      must imply a slice of size 1 in the dimension. For example in
      python one might do `foo[:, 3, :]` which would result in
      `shrink_axis_mask` being 2.
    name: A name for the operation (optional).

  Returns:
    A `Tensor`. Has the same type as `input`.
