// Spectrograms are a standard way of representing audio information as a series of

// over time.
//
// This op expects to receive audio data as an input, stored as floats in the range
// -1 to 1, together with a window width in samples, and a stride specifying how
// far to move the window between slices. From this it generates a three
// dimensional output. The first dimension is for the channels in the input, so a
// stereo audio input would have two here for example. The second dimension is time,
// with successive frequency slices. The third dimension has an amplitude value for
// each frequency during that time slice.
//
// This means the layout when converted and saved as an image is rotated 90 degrees
// clockwise from a typical spectrogram. Time is descending down the Y axis, and
// the frequency decreases from left to right.
//
// Each value in the result represents the square root of the sum of the real and
// imaginary parts of an FFT on the current window of samples. In this way, the
// lowest dimension represents the power of each frequency in the current window,
// and adjacent windows are concatenated in the next dimension.
//
// To get a more intuitive and visual look at what this operation does, you can run
// tensorflow/examples/wav_to_spectrogram to read in an audio file and save out the
// resulting spectrogram as a PNG image.

// Arguments:

// Broadcast an array for a compatible shape.
//
// 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.
//
// For example:
//
// >>> x = tf.constant([[1, 2, 3]])   # Shape (1, 3,)
// >>> y = tf.broadcast_to(x, [2, 3])
// >>> print(y)
// tf.Tensor(
//
//	[[1 2 3]
//	 [1 2 3]], shape=(2, 3), dtype=int32)
//
// In the above example, the input Tensor with the shape of `[1, 3]`
// is broadcasted to output Tensor with shape of `[2, 3]`.
//
// When broadcasting, if a tensor has fewer axes than necessary its shape is
// padded on the left with ones. So this gives the same result as the previous
// example:
//
// >>> x = tf.constant([1, 2, 3])   # Shape (3,)
// >>> y = tf.broadcast_to(x, [2, 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.)

// The op extracts fields from a serialized protocol buffers message into tensors.
//
// Note: This API is designed for orthogonality rather than human-friendliness. It
// can be used to parse input protos by hand, but it is intended for use in
// generated code.
//
// The `decode_proto` op extracts fields from a serialized protocol buffers
// message into tensors.  The fields in `field_names` are decoded and converted
// to the corresponding `output_types` if possible.
//
// A `message_type` name must be provided to give context for the field names.
// The actual message descriptor can be looked up either in the linked-in
// descriptor pool or a filename provided by the caller using the
// `descriptor_source` attribute.
//
// Each output tensor is a dense tensor. This means that it is padded to hold
// the largest number of repeated elements seen in the input minibatch. (The
// shape is also padded by one to prevent zero-sized dimensions). The actual
// repeat counts for each example in the minibatch can be found in the `sizes`
// output. In many cases the output of `decode_proto` is fed immediately into
// tf.squeeze if missing values are not a concern. When using tf.squeeze, always
// pass the squeeze dimension explicitly to avoid surprises.
//
// For the most part, the mapping between Proto field types and TensorFlow dtypes
// is straightforward. However, there are a few special cases:
//
// - A proto field that contains a submessage or group can only be converted
// to `DT_STRING` (the serialized submessage). This is to reduce the complexity
// of the API. The resulting string can be used as input to another instance of
// the decode_proto op.
//
// - TensorFlow lacks support for unsigned integers. The ops represent uint64
// types as a `DT_INT64` with the same twos-complement bit pattern (the obvious
// way). Unsigned int32 values can be represented exactly by specifying type
// `DT_INT64`, or using twos-complement if the caller specifies `DT_INT32` in
// the `output_types` attribute.
//
// - `map` fields are not directly decoded. They are treated as `repeated` fields,
// of the appropriate entry type. The proto-compiler defines entry types for each
// map field. The type-name is the field name, converted to "CamelCase" with
// "Entry" appended. The `tf.train.Features.FeatureEntry` message is an example of
// one of these implicit `Entry` types.
//
// - `enum` fields should be read as int32.
//
// Both binary and text proto serializations are supported, and can be
// chosen using the `format` attribute.
//
// The `descriptor_source` attribute selects the source of protocol
// descriptors to consult when looking up `message_type`. This may be:
//
// - An empty string  or "local://", in which case protocol descriptors are
// created for C++ (not Python) proto definitions linked to the binary.
//
// - A file, in which case protocol descriptors are created from the file,
// which is expected to contain a `FileDescriptorSet` serialized as a string.
// NOTE: You can build a `descriptor_source` file using the `--descriptor_set_out`
// and `--include_imports` options to the protocol compiler `protoc`.
//
// - A "bytes://<bytes>", in which protocol descriptors are created from `<bytes>`,
// which is expected to be a `FileDescriptorSet` serialized as a string.
//
// Arguments:
//
//	bytes: Tensor of serialized protos with shape `batch_shape`.
//	message_type: Name of the proto message type to decode.
//	field_names: List of strings containing proto field names. An extension field can be decoded
//
// by using its full name, e.g. EXT_PACKAGE.EXT_FIELD_NAME.
//
//	output_types: List of TF types to use for the respective field in field_names.
//
// Returns:
//
//	sizes: Tensor of int32 with shape `[batch_shape, len(field_names)]`.
//
// Each entry is the number of values found for the corresponding field.
// Optional fields may have 0 or 1 values.

// 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 of 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`.

//
//	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

// 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]]]]
//
// ```

//
//	 [5, 6, 7, 8]],
//	[[9, 10, 11, 12],

// Tensor contraction according to Einstein summation convention.
//
// 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`.

// The op serializes protobuf messages provided in the input tensors.
//
// The types of the tensors in `values` must match the schema for the fields
// specified in `field_names`. All the tensors in `values` must have a common
// shape prefix, *batch_shape*.
//
// The `sizes` tensor specifies repeat counts for each field.  The repeat count
// (last dimension) of a each tensor in `values` must be greater than or equal
// to corresponding repeat count in `sizes`.
//
// A `message_type` name must be provided to give context for the field names.
// The actual message descriptor can be looked up either in the linked-in
// descriptor pool or a filename provided by the caller using the
// `descriptor_source` attribute.
//
// For the most part, the mapping between Proto field types and TensorFlow dtypes
// is straightforward. However, there are a few special cases:
//
// - A proto field that contains a submessage or group can only be converted
// to `DT_STRING` (the serialized submessage). This is to reduce the complexity
// of the API. The resulting string can be used as input to another instance of
// the decode_proto op.
//
// - TensorFlow lacks support for unsigned integers. The ops represent uint64
// types as a `DT_INT64` with the same twos-complement bit pattern (the obvious
// way). Unsigned int32 values can be represented exactly by specifying type
// `DT_INT64`, or using twos-complement if the caller specifies `DT_INT32` in
// the `output_types` attribute.
//
// The `descriptor_source` attribute selects the source of protocol
// descriptors to consult when looking up `message_type`. This may be:
//
// - An empty string  or "local://", in which case protocol descriptors are
// created for C++ (not Python) proto definitions linked to the binary.
//
// - A file, in which case protocol descriptors are created from the file,
// which is expected to contain a `FileDescriptorSet` serialized as a string.
// NOTE: You can build a `descriptor_source` file using the `--descriptor_set_out`
// and `--include_imports` options to the protocol compiler `protoc`.
//
// - A "bytes://<bytes>", in which protocol descriptors are created from `<bytes>`,
// which is expected to be a `FileDescriptorSet` serialized as a string.
//
// Arguments:
//
//	sizes: Tensor of int32 with shape `[batch_shape, len(field_names)]`.
//	values: List of tensors containing values for the corresponding field.
//	field_names: List of strings containing proto field names.
//	message_type: Name of the proto message type to decode.

// default method `farmhash64` generates a 64-bit fingerprint value at a time.
// This 8-byte value is written out as an `uint8` array of size 8, in little-endian
// order.
//
// For example, suppose that `data` has data type `DT_INT32` and shape (2, 3, 4),
// and that the fingerprint method is `farmhash64`. In this case, the output shape
// is (2, 8), where 2 is the batch dimension size of `data`, and 8 is the size of
// each fingerprint value in bytes. `output[0, :]` is generated from 12 integers in
// `data[0, :, :]` and similarly `output[1, :]` is generated from other 12 integers
// in `data[1, :, :]`.
//
// Note that this op fingerprints the raw underlying buffer, and it does not
// fingerprint Tensor's metadata such as data type and/or shape. For example, the
// fingerprint values are invariant under reshapes and bitcasts as long as the
// batch dimension remain the same:
//
// ```
// Fingerprint(data) == Fingerprint(Reshape(data, ...))
// Fingerprint(data) == Fingerprint(Bitcast(data, ...))
// ```
//
// For string data, one should expect `Fingerprint(data) !=
// Fingerprint(ReduceJoin(data))` in general.
//
// Arguments:
//
//	data: Must have rank 1 or higher.
//	method: Fingerprint method used by this op. Currently available method is

// Performs fractional max pooling on the input.

// Fractional max pooling is slightly different than regular max pooling.  In
// regular max pooling, you downsize an input set by taking the maximum value of
// smaller N x N subsections of the set (often 2x2), and try to reduce the set by
// a factor of N, where N is an integer.  Fractional max pooling, as you might
// expect from the word "fractional", means that the overall reduction ratio N
// does not have to be an integer.
//
// The sizes of the pooling regions are generated randomly but are fairly uniform.
// For example, let's look at the height dimension, and the constraints on the
// list of rows that will be pool boundaries.
//
// First we define the following:
//
// 1.  input_row_length : the number of rows from the input set
// 2.  output_row_length : which will be smaller than the input
// 3.  alpha = input_row_length / output_row_length : our reduction ratio
// 4.  K = floor(alpha)
// 5.  row_pooling_sequence : this is the result list of pool boundary rows
//
// Then, row_pooling_sequence should satisfy:
//
// 1.  a[0] = 0 : the first value of the sequence is 0
// 2.  a[end] = input_row_length : the last value of the sequence is the size
// 3.  K <= (a[i+1] - a[i]) <= K+1 : all intervals are K or K+1 size
// 4.  length(row_pooling_sequence) = output_row_length+1

//
// *  1: `tensor` is interpreted as Grayscale.
// *  3: `tensor` is interpreted as RGB.
// *  4: `tensor` is interpreted as RGBA.
//
// The images have the same number of channels as the input tensor. For float
// input, the values are normalized one image at a time to fit in the range
// `[0, 255]`.  `uint8` values are unchanged.  The op uses two different
// normalization algorithms:
//
//   - If the input values are all positive, they are rescaled so the largest one
//     is 255.
//
//   - If any input value is negative, the values are shifted so input value 0.0
//     is at 127.  They are then rescaled so that either the smallest value is 0,

//
// The `tag` argument is a scalar `Tensor` of type `string`.  It is used to
// build the `tag` of the summary values:
//
//   - If `max_images` is 1, the summary value tag is '*tag*/image'.
//   - If `max_images` is greater than 1, the summary value tags are
//     generated sequentially as '*tag*/image/0', '*tag*/image/1', etc.
//

// Each element must be in the range `[0, 255]` (It represents the value of a

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

//
// which the old matrix `Tensor` will be loaded.
//
//	old_tensor_name: Name of the 2-D `Tensor` to load from checkpoint.
//	row_remapping: An int `Tensor` of row remappings (generally created by
//
// `generate_vocab_remapping`).  Even if no row remapping is needed, this must
// still be an index-valued Tensor (e.g. [0, 1, 2, ...]), or a shifted
// index-valued `Tensor` (e.g. [8, 9, 10, ...], for partitioned `Variables`).
//

//
// 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

//
// ```python
//
//	indices[0] = 6

//	data[0] = [61, 62]

//	          [51, 52], [61, 62]]
//
// ```
//

// 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])

//	partitioned_data = tf.dynamic_partition(

// [input_min, input_max] range to a range that lies within the representable
// quantized range.

// 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.
//

// 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`, the quantization is performed by multiplying each
// input value by a scaling_factor.
// The scaling_factor is determined from `min_range` and `max_range` to be as large
// as possible such that the range from `min_range` to `max_range` is representable
// within values of type T.
//
// ```c++
//
//	const int min_T = std::numeric_limits<T>::min();
//	const int max_T = std::numeric_limits<T>::max();
//	const float max_float = std::numeric_limits<float>::max();
//
//	const float scale_factor_from_min_side =
//	    (min_T * min_range > 0) ? min_T / min_range : max_float;
//	const float scale_factor_from_max_side =
//	    (max_T * max_range > 0) ? max_T / max_range : max_float;
//
//	const float scale_factor = std::min(scale_factor_from_min_side,
//	                                    scale_factor_from_max_side);
//
// ```
//
// We next use the scale_factor to adjust min_range and max_range as follows:
//
// ```c++
//
//	min_range = min_T / scale_factor;
//	max_range = max_T / scale_factor;
//
// ```
//
// e.g. if T = qint8, and initially min_range = -10, and max_range = 9, we would
// compare -128/-10.0 = 12.8 to 127/9.0 = 14.11, and set scaling_factor = 12.8
// In this case, min_range would remain -10, but max_range would be adjusted to
// 127 / 12.8 = 9.921875
//
// So we will quantize input values in the range (-10, 9.921875) to (-128, 127).
//
// The input tensor can now be quantized by clipping values to the range
// `min_range` to `max_range`, then multiplying by scale_factor as follows:
//
// ```c++
// result = round(min(max_range, max(min_range, input)) * scale_factor)
// ```
//
// The adjusted `min_range` and `max_range` are returned as outputs 2 and 3 of
// this operation. These outputs should be used as the range for any further
// calculations.
//
// *narrow_range (bool) attribute*
//
// If true, we do not use the minimum quantized value.
// i.e. for int8 the quantized output, it would be restricted to the range
// -127..127 instead of the full -128..127 range.
// This is provided for compatibility with certain inference backends.
// (Only applies to SCALED mode)
//
// *axis (int) attribute*
//
// An optional `axis` attribute can specify a dimension index of the input tensor,
// such that quantization ranges will be calculated and applied separately for each
// slice of the tensor along that dimension. This is useful for per-channel
// quantization.
//
// If axis is specified, min_range and max_range
//
// if `axis`=None, per-tensor quantization is performed as normal.
//
// *ensure_minimum_range (float) attribute*
//
// Ensures the minimum quantization range is at least this value.
// The legacy default value for this is 0.01, but it is strongly suggested to
// set it to 0 for new uses.
//
// Arguments:
//
//	min_range: The minimum value of the quantization range. This value may be adjusted by the
//
// op depending on other parameters. The adjusted value is written to `output_min`.
// If the `axis` attribute is specified, this must be a 1-D tensor whose size
// matches the `axis` dimension of the input and output tensors.
//
//	max_range: The maximum value of the quantization range. This value may be adjusted by the
//
// op depending on other parameters. The adjusted value is written to `output_max`.
// If the `axis` attribute is specified, this must be a 1-D tensor whose size
// matches the `axis` dimension of the input and output tensors.
//
// Returns:
//
//	output: The quantized data produced from the float input.
//	output_min: The final quantization range minimum, used to clip input values before scaling
//
// and rounding them to quantized values.
// If the `axis` attribute is specified, this will be a 1-D tensor whose size
// matches the `axis` dimension of the input and output tensors.
//
//	output_max: The final quantization range maximum, used to clip input values before scaling
//
// and rounding them to quantized values.
// If the `axis` attribute is specified, this will be a 1-D tensor whose size
// matches the `axis` dimension of the input and output tensors.

// localization of an object, i.e. bounding box, given an `image_size`,
// `bounding_boxes` and a series of constraints.
//
// The output of this Op is a single bounding box that may be used to crop the
// original image. The output is returned as 3 tensors: `begin`, `size` and
// `bboxes`. The first 2 tensors can be fed directly into `tf.slice` to crop the
// image. The latter may be supplied to `tf.image.draw_bounding_boxes` to visualize
// what the bounding box looks like.
//
// Bounding boxes are supplied and returned as `[y_min, x_min, y_max, x_max]`. The
// bounding box coordinates are floats in `[0.0, 1.0]` relative to the width and
// height of the underlying image.
//
// For example,
//
// ```python
//
//	# Generate a single distorted bounding box.
//	begin, size, bbox_for_draw = tf.image.sample_distorted_bounding_box(
//	    tf.shape(image),
//	    bounding_boxes=bounding_boxes)

//	tf.summary.image('images_with_box', image_with_box)
//
//	# Employ the bounding box to distort the image.
//	distorted_image = tf.slice(image, begin, size)
//
// ```
//
// Note that if no bounding box information is available, setting
// `use_image_if_no_bounding_boxes = true` will assume there is a single implicit
// bounding box covering the whole image. If `use_image_if_no_bounding_boxes` is

// Generate a single randomly distorted bounding box for an image.
//
// Bounding box annotations are often supplied in addition to ground-truth labels
// in image recognition or object localization tasks. A common technique for
// training such a system is to randomly distort an image while preserving
// its content, i.e. *data augmentation*. This Op outputs a randomly distorted
// localization of an object, i.e. bounding box, given an `image_size`,
// `bounding_boxes` and a series of constraints.
//
// The output of this Op is a single bounding box that may be used to crop the
// original image. The output is returned as 3 tensors: `begin`, `size` and
// `bboxes`. The first 2 tensors can be fed directly into `tf.slice` to crop the
// image. The latter may be supplied to `tf.image.draw_bounding_boxes` to visualize
// what the bounding box looks like.
//
// Bounding boxes are supplied and returned as `[y_min, x_min, y_max, x_max]`. The
// bounding box coordinates are floats in `[0.0, 1.0]` relative to the width and
// height of the underlying image.
//
// For example,
//
// ```python
//
//	# Generate a single distorted bounding box.
//	begin, size, bbox_for_draw = tf.image.sample_distorted_bounding_box(
//	    tf.shape(image),
//	    bounding_boxes=bounding_boxes)
//
//	# Draw the bounding box in an image summary.
//	image_with_box = tf.image.draw_bounding_boxes(tf.expand_dims(image, 0),
//	                                              bbox_for_draw)
//	tf.summary.image('images_with_box', image_with_box)
//
//	# Employ the bounding box to distort the image.
//	distorted_image = tf.slice(image, begin, size)
//
// ```
//
// Note that if no bounding box information is available, setting
// `use_image_if_no_bounding_boxes = true` will assume there is a single implicit
// bounding box covering the whole image. If `use_image_if_no_bounding_boxes` is
// false and no bounding boxes are supplied, an error is raised.
//
// Arguments:
//
//	image_size: 1-D, containing `[height, width, channels]`.

// If `indices` contains duplicates, the associated `updates` are accumulated

// 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

//
// 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]]]]
//
// ```

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

//	[[9],  [10], [13],  [14]],

//
// ```
//

// deterministically outputs a randomly distorted localization of an object, i.e.
// bounding box, given an `image_size`, `bounding_boxes` and a series of
// constraints.
//
// The output of this Op is a single bounding box that may be used to crop the
// original image. The output is returned as 3 tensors: `begin`, `size` and
// `bboxes`. The first 2 tensors can be fed directly into `tf.slice` to crop the
// image. The latter may be supplied to `tf.image.draw_bounding_boxes` to visualize
// what the bounding box looks like.
//
// Bounding boxes are supplied and returned as `[y_min, x_min, y_max, x_max]`. The
// bounding box coordinates are floats in `[0.0, 1.0]` relative to the width and
// the height of the underlying image.

// The output of this Op is guaranteed to be the same given the same `seed` and is

// seed settings (e.g. `tf.random.set_seed`).
//
// Example usage:
//
// >>> image = np.array([[[1], [2], [3]], [[4], [5], [6]], [[7], [8], [9]]])
// >>> bbox = tf.constant(
// ...   [0.0, 0.0, 1.0, 1.0], dtype=tf.float32, shape=[1, 1, 4])
// >>> seed = (1, 2)
// >>> # Generate a single distorted bounding box.
// >>> bbox_begin, bbox_size, bbox_draw = (
// ...   tf.image.stateless_sample_distorted_bounding_box(
// ...     tf.shape(image), bounding_boxes=bbox, seed=seed))
// >>> # Employ the bounding box to distort the image.
// >>> tf.slice(image, bbox_begin, bbox_size)
// <tf.Tensor: shape=(2, 2, 1), dtype=int64, numpy=
// array([[[1],
//
//	 [2]],
//	[[4],
//	 [5]]])>
//
// >>> # Draw the bounding box in an image summary.
// >>> colors = np.array([[1.0, 0.0, 0.0], [0.0, 0.0, 1.0]])
// >>> tf.image.draw_bounding_boxes(

// bounding box covering the whole image. If `use_image_if_no_bounding_boxes` is
// false and no bounding boxes are supplied, an error is raised.
//
// Arguments:
//
//	image_size: 1-D, containing `[height, width, channels]`.
//	bounding_boxes: 3-D with shape `[batch, N, 4]` describing the N bounding boxes
//
// associated with the image.
//

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

// When building ops to compute gradients, this op prevents the contribution of
// its inputs to be taken into account.  Normally, the gradient generator adds ops
// to a graph to compute the derivatives of a specified 'loss' by recursively
// finding out inputs that contributed to its computation.  If you insert this op
// in the graph it inputs are masked from the gradient generator.  They are not
// taken into account for computing gradients.
//
// This is useful any time you want to compute a value with TensorFlow but need
// to pretend that the value was a constant. 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

// 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 = 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)`
//
// Arguments:
//
//	begin: `begin[k]` specifies the offset into the `k`th range specification.
//
// The exact dimension this corresponds to will be determined by context.
// Out-of-bounds values will be silently clamped. If the `k`th bit of
// `begin_mask` then `begin[k]` is ignored and the full range of the
// appropriate dimension is used instead. Negative values causes indexing
// to start from the highest element e.g. If `foo==[1,2,3]` then `foo[-1]==3`.
//
//	end: `end[i]` is like `begin` with the exception that `end_mask` is
//
// used to determine full ranges.
//
//	strides: `strides[i]` specifies the increment in the `i`th specification
//
// after extracting a given element. Negative indices will reverse
// the original order. Out or range values are
// clamped to `[0,dim[i]) if slice[i]>0` or `[-1,dim[i]-1] if slice[i] < 0`

// 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

// memory for the existing tensor cannot be re-used, a copy is made and updated.

// `tensor.shape`.  The last dimension of `indices` can be at most the rank of
// `tensor.shape`:
//
// ```
// indices.shape[-1] <= tensor.shape.rank

//
// ```

// tensor with 8 elements.

// In Python, this scatter add operation would look like this:
//
// >>> indices = tf.constant([[4], [3], [1], [7]])
// >>> updates = tf.constant([9, 10, 11, 12])
// >>> tensor = tf.ones([8], dtype=tf.int32)

// <tf.Tensor: shape=(8,), dtype=int32,
// numpy=array([ 1, 12,  1, 11, 10,  1,  1, 13], dtype=int32)>
//
// 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:
//
// >>> 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]]])

// `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`:
//

// ```python

// The resulting tensor would look like this:
//
//	[1, -10, 1, -9, -8, 1, 1, -11]
//
// We can also, insert entire slices of a higher rank tensor all at once. For
// example, if we wanted to insert two slices in the first dimension of a
// rank-3 tensor with two matrices of new values.
//
// In Python, this scatter add operation would look like this:

// ```python
//
//	indices = tf.constant([[0], [2]])
