    Given `tensor`, this operation returns a tensor that has the same values
    as `tensor` with shape `shape`.
    If one component of 1-D tensor `shape` is the special value -1, the size of that
    dimension is computed so that the total size remains constant.  In particular, a

/** 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) print(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) 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]],
         [[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.

    `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`.

/** SpaceToBatch for 4-D tensors of type T.
    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.
    Arguments:
    * scope: A Scope object
    * input: 4-D with shape `[batch, height, width, depth]`.
    * paddings: 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_pad = pad_left + width + pad_right
    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]
    Some examples:
    (1) For the following input of shape `[1, 2, 2, 1]` and block_size of 2:

/** 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.
    Arguments:
    * scope: A Scope object
    * 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:
    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],

/** 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]]]]

      `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:
    * scope: A Scope object
    * begin: begin[k] specifies the offset into the kth range specification.
    The exact dimension this corresponds to will be determined by context.
    Out-of-bounds values will be silently clamped. If the kth 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 ith 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
    Optional attributes (see Attrs):
    * begin_mask: 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: analogous to begin_mask
    * ellipsis_mask: a bitmask where bit i being 1 means the ith
    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: a bitmask where bit i being 1 means the ith
    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: a bitmask where bit i implies that the ith
    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.
    Returns:
    * Output: The output tensor. */

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:

    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_nd_update(tensor, indices, updates) print(updated) 

  

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

  

    
    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.

/** Returns locations of nonzero / true values in a tensor.
    This operation returns the coordinates of true elements in `condition`. The
    coordinates are returned in a 2-D tensor where the first dimension (rows)
    represents the number of true elements, and the second dimension (columns)
    represents the coordinates of the true elements. Keep in mind, the shape of
    the output tensor can vary depending on how many true values there are in
    `condition`. Indices are output in row-major order.
    For example:
    
'input' tensor is [[True, False]
  

  

    
[True, False]]
  

  

    
'input' has two true values, so output has two coordinates.
  

  

    
'input' has rank of 2, so coordinates have two indices.
  

  
where(input) ==> [[0, 0], [1, 0]]
  

    
condition tensor is [[[True, False]
  

  

    
[True, False]]
  

  

    
[[False, True]
  

  

    
[False, True]]
  

  

    
[[False, False]
  

  

    
[False, True]]]
  

  

    
'input' has 5 true values, so output has 5 coordinates.
  

  

    
'input' has rank of 3, so coordinates have three indices.
  

  
where(input) ==> [[0, 0, 0], [0, 1, 0], [1, 0, 1], [1, 1, 1], [2, 1, 1]]
  

    
condition tensor is [[[1.5, 0.0]
  

  

    
[-0.5, 0.0]]
  

  

    
[[0.0, 0.25]
  

  

    
[0.0, 0.75]]
  

  

    
[[0.0, 0.0]
  

  

    
[0.0, 0.01]]]
  

  

    
'input' has 5 nonzero values, so output has 5 coordinates.
  

  

    
'input' has rank of 3, so coordinates have three indices.
  

  
where(input) ==> [[0, 0, 0], [0, 1, 0], [1, 0, 1], [1, 1, 1], [2, 1, 1]]
  

    
condition tensor is [[[1.5 + 0.0j, 0.0 + 0.0j]
  

  

    
[0.0 + 0.5j, 0.0 + 0.0j]]
  

  

    
[[0.0 + 0.0j, 0.25 + 1.5j]
  

  

    
[0.0 + 0.0j, 0.75 + 0.0j]]
  

  

    
[[0.0 + 0.0j, 0.0 + 0.0j]
  

  

    
[0.0 + 0.0j, 0.01 + 0.0j]]]
  

  

    
'input' has 5 nonzero magnitude values, so output has 5 coordinates.
  

  

    
'input' has rank of 3, so coordinates have three indices.
  

  
where(input) ==> [[0, 0, 0], [0, 1, 0], [1, 0, 1], [1, 1, 1], [2, 1, 1]] ```
