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

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

  codes = tf.bitcast(codes, tf.int32)  # go from uint8 to int32
  # now codes has shape x.shape[:-1] + [codebook_size]
  ```

**NOTE**: Currently, the innermost dimension of the tensor must be divisible

def cumulative_logsumexp(x, axis, exclusive=False, reverse=False, name=None):
  r"""Compute the cumulative product of the tensor `x` along `axis`.

By default, this op performs an inclusive cumulative log-sum-exp,
  which means that the first
  element of the input is identical to the first element of the output:
  ```python
  tf.math.cumulative_logsumexp([a, b, c])  # => [a, log(exp(a) + exp(b)), log(exp(a) + exp(b) + exp(c))]
  ```

By setting the `exclusive` kwarg to `True`, an exclusive cumulative log-sum-exp is
  performed instead:
  ```python
  tf.cumulative_logsumexp([a, b, c], exclusive=True)  # => [-inf, a, log(exp(a) * exp(b))]
  ```
  Note that the neutral element of the log-sum-exp operation is `-inf`,
  however, for performance reasons, the minimal value representable by the
  floating point type is used instead.

By setting the `reverse` kwarg to `True`, the cumulative log-sum-exp is performed in the
  opposite direction.

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

This function computes the exponential of every element in the input tensor.

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

```python
    x = tf.constant(2.0)

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

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

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

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

def quantize_down_and_shrink_range(input, input_min, input_max, out_type, name=None):
  r"""Convert the quantized 'input' tensor into a lower-precision 'output', using the

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

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

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

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

Returns:
    A tuple of `Tensor` objects (output, output_min, output_max).

output: A `Tensor` of type `out_type`.
    output_min: A `Tensor` of type `float32`.
    output_max: A `Tensor` of type `float32`.

  r"""Converts the quantized `input` tensor into a lower-precision `output`.

Converts the quantized `input` tensor into a lower-precision `output`, using the
  output range specified with `requested_output_min` and `requested_output_max`.

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

Args:
    input: A `Tensor`. Must be one of the following types: `qint8`, `quint8`, `qint32`, `qint16`, `quint16`.
    input_min: A `Tensor` of type `float32`.
      The float value that the minimum quantized input value represents.
    input_max: A `Tensor` of type `float32`.
      The float value that the maximum quantized input value represents.
    requested_output_min: A `Tensor` of type `float32`.
      The float value that the minimum quantized output value represents.
    requested_output_max: A `Tensor` of type `float32`.
      The float value that the maximum quantized output value represents.
    out_type: A `tf.DType` from: `tf.qint8, tf.quint8, tf.qint32, tf.qint16, tf.quint16`.
      The type of the output. Should be a lower bit depth than Tinput.
    name: A name for the operation (optional).

Returns:
    A tuple of `Tensor` objects (output, output_min, output_max).

output: A `Tensor` of type `out_type`.

  If `x` and `y` are vectors or higher rank, then `condition` must be either a

The `condition` tensor acts as a mask that chooses, based on the value at each

  taken from `x` (if true) or `y` (if false).

If `condition` is a vector and `x` and `y` are higher rank matrices, then
  it chooses which row (outer dimension) to copy from `x` and `y`.
  If `condition` has the same shape as `x` and `y`, then it chooses which
  element to copy from `x` and `y`.

  r"""Multiply matrix "a" by matrix "b".

The inputs must be two-dimensional matrices and the inner dimension of "a" must
  match the outer dimension of "b". Both "a" and "b" must be `Tensor`s not
  `SparseTensor`s.  This op is optimized for the case where at least one of "a" or
  "b" is sparse, in the sense that they have a large proportion of zero values.
  The breakeven for using this versus a dense matrix multiply on one platform was
  30% zero values in the sparse matrix.

The gradient computation of this operation will only take advantage of sparsity
  in the input gradient when that gradient comes from a Relu.

Args:
    a: A `Tensor`. Must be one of the following types: `float32`, `bfloat16`.
    b: A `Tensor`. Must be one of the following types: `float32`, `bfloat16`.
    transpose_a: An optional `bool`. Defaults to `False`.

    a_is_sparse: An optional `bool`. Defaults to `False`.
    b_is_sparse: An optional `bool`. Defaults to `False`.

Returns:

Read
  [the section on segmentation](https://tensorflow.org/api_docs/python/tf/math#Segmentation)
  for an explanation of segments.

Like `SegmentSum`, but `segment_ids` can have rank less than `data`'s first
  dimension, selecting a subset of dimension 0, specified by `indices`.

For example:

```python
  c = tf.constant([[1,2,3,4], [-1,-2,-3,-4], [5,6,7,8]])

# Select two rows, one segment.
  tf.sparse_segment_sum(c, tf.constant([0, 1]), tf.constant([0, 0]))
  # => [[0 0 0 0]]

# Select two rows, two segment.
  tf.sparse_segment_sum(c, tf.constant([0, 1]), tf.constant([0, 1]))
  # => [[ 1  2  3  4]
  #     [-1 -2 -3 -4]]

# Select all rows, two segments.
  tf.sparse_segment_sum(c, tf.constant([0, 1, 2]), tf.constant([0, 0, 1]))
  # => [[0 0 0 0]
  #     [5 6 7 8]]

# Which is equivalent to:
  tf.segment_sum(c, tf.constant([0, 0, 1]))
  ```

    indices: A `Tensor`. Must be one of the following types: `int32`, `int64`.
      A 1-D tensor. Has same rank as `segment_ids`.
    segment_ids: A `Tensor`. Must be one of the following types: `int32`, `int64`.

  for an explanation of segments.

This operator is similar to the unsorted segment sum operator found
  [(here)](../../../api_docs/python/math_ops.md#UnsortedSegmentSum).
  Instead of computing the sum over segments, it computes the maximum such that:

\\(output_i = \max_{j...} data[j...]\\) where max is over tuples `j...` such
  that `segment_ids[j...] == i`.

If the maximum is empty for a given segment ID `i`, it outputs the smallest
  possible value for the specific numeric type,
  `output[i] = numeric_limits<T>::lowest()`.

If the given segment ID `i` is negative, then the corresponding value is
  dropped, and will not be included in the result.

For example:

``` python
  c = tf.constant([[1,2,3,4], [5,6,7,8], [4,3,2,1]])
  tf.unsorted_segment_max(c, tf.constant([0, 1, 0]), num_segments=2)

\\(output_i = \min_{j...} data_[j...]\\) where min is over tuples `j...` such
  that `segment_ids[j...] == i`.

If the minimum is empty for a given segment ID `i`, it outputs the largest
  possible value for the specific numeric type,
  `output[i] = numeric_limits<T>::max()`.

For example:

``` python
  c = tf.constant([[1,2,3,4], [5,6,7,8], [4,3,2,1]])
  tf.unsorted_segment_min(c, tf.constant([0, 1, 0]), num_segments=2)
  # ==> [[ 1,  2, 2, 1],
  #       [5,  6, 7, 8]]
  ```

If the given segment ID `i` is negative, then the corresponding value is
  dropped, and will not be included in the result.

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

Args:
    x: A `Tensor`. Must be one of the following types: `float32`, `float64`.
    q: A `Tensor`. Must have the same type as `x`.
    name: A name for the operation (optional).

Returns:
