tf.searchsorted(
    sorted_sequence, values, side='left', out_type=tf.dtypes.int32, name=None
)

A 2-D example:

  sorted_sequence = [[0, 3, 9, 9, 10],
                     [1, 2, 3, 4, 5]]
  values = [[2, 4, 9],
            [0, 2, 6]]

  result = searchsorted(sorted_sequence, values, side="left")

  result == [[1, 2, 2],
             [0, 1, 5]]

  result = searchsorted(sorted_sequence, values, side="right")

  result == [[1, 2, 4],
             [0, 2, 5]]

Args
sorted_sequence	N-D Tensor containing a sorted sequence.
values	N-D Tensor containing the search values.
side	'left' or 'right'; 'left' corresponds to lower_bound and 'right' to upper_bound.
out_type	The output type (int32 or int64). Default is tf.int32.
name	Optional name for the operation.

Returns
An N-D Tensor the size of values containing the result of applying either lower_bound or upper_bound (depending on side) to each value. The result is not a global index to the entire Tensor, but the index in the last dimension.

Raises
ValueError	If the last dimension of sorted_sequence >= 2^31-1 elements. If the total size of values exceeds 2^31 - 1 elements. If the first N-1 dimensions of the two tensors don't match.
