tf.compat.v1.raw_ops.LowerBound

tf.raw_ops.LowerBound(
    sorted_inputs, values, out_type=tf.dtypes.int32, name=None
)

Each set of rows with the same index in (sorted_inputs, values) is treated independently. The resulting row is the equivalent of calling np.searchsorted(sorted_inputs, values, side='left').

The result is not a global index to the entire Tensor, but rather just the index in the last dimension.

A 2-D example: sorted_sequence = [[0, 3, 9, 9, 10], [1, 2, 3, 4, 5]] values = [[2, 4, 9], [0, 2, 6]]

result = LowerBound(sorted_sequence, values)

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

Args
sorted_inputs	A Tensor. 2-D Tensor where each row is ordered.
values	A Tensor. Must have the same type as sorted_inputs. 2-D Tensor with the same numbers of rows as sorted_search_values. Contains the values that will be searched for in sorted_search_values.
out_type	An optional tf.DType from: tf.int32, tf.int64. Defaults to tf.int32.
name	A name for the operation (optional).

Returns
A Tensor of type out_type.
