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

def compare_and_bitpack(input, threshold, name=None):
  r"""Compare values of `input` to `threshold` and pack resulting bits into a `uint8`.

  Each comparison returns a boolean `true` (if `input_value > threshold`)
  or and `false` otherwise.

  This operation is useful for Locality-Sensitive-Hashing (LSH) and other
  algorithms that use hashing approximations of cosine and `L2` distances;
  codes can be generated from an input via:

  ```python
  codebook_size = 50
  codebook_bits = codebook_size * 32
  codebook = tf.get_variable('codebook', [x.shape[-1].value, codebook_bits],
                             dtype=x.dtype,
                             initializer=tf.orthogonal_initializer())
  codes = compare_and_threshold(tf.matmul(x, codebook), threshold=0.)
  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
  by 8.

  Given an `input` shaped `[s0, s1, ..., s_n]`, the output is
  a `uint8` tensor shaped `[s0, s1, ..., s_n / 8]`.

  Args:
    input: A `Tensor`. Must be one of the following types: `bool`, `half`, `float32`, `float64`, `int8`, `int16`, `int32`, `int64`.
      Values to compare against `threshold` and bitpack.
    threshold: A `Tensor`. Must have the same type as `input`.
      Threshold to compare against.
    name: A name for the operation (optional).

  Returns:
    A `Tensor` of type `uint8`.

  ```python

  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.

  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 type of the output. Should be a lower bit depth than Tinput.

  Computes a tensor such that

  If the sum is empty for a given segment ID `i`, `output[i] = 0`.

  r"""Selects elements from `x` or `y`, depending on `condition`.

  The `x`, and `y` tensors must all have the same shape, and the
  output will also have that shape.

  The `condition` tensor must be a scalar if `x` and `y` are scalars.
  If `x` and `y` are vectors or higher rank, then `condition` must be either a
  scalar, a vector with size matching the first dimension of `x`, or must have
  the same shape as `x`.

  The `condition` tensor acts as a mask that chooses, based on the value at each
  element, whether the corresponding element / row in the output should be
  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`.

  For example:

  ```python
  # 'condition' tensor is [[True,  False]
  #                        [False, True]]
  # 't' is [[1, 2],
  #         [3, 4]]
  # 'e' is [[5, 6],
  #         [7, 8]]
  select(condition, t, e)  # => [[1, 6], [7, 4]]


  # 'condition' tensor is [True, False]
  # 't' is [[1, 2],
  #         [3, 4]]
  # 'e' is [[5, 6],
  #         [7, 8]]
  select(condition, t, e) ==> [[1, 2],
                               [7, 8]]

  ```

  Args:

    is `[-inf,inf]`.

    x = tf.constant([-float("inf"), -9, -0.5, 1, 1.2, 2, 10, float("inf")])
    tf.math.sinh(x) ==> [-inf -4.0515420e+03 -5.2109528e-01 1.1752012e+00 1.5094614e+00 3.6268604e+00 1.1013232e+04 inf]
    ```

  Args:
    x: A `Tensor`. Must be one of the following types: `bfloat16`, `half`, `float32`, `float64`, `complex64`, `complex128`.
    name: A name for the operation (optional).

  Returns:
