tensorflow:: ops:: UnsortedSegmentJoin
#include <string_ops.h>
Joins the elements of inputs
based on segment_ids
.
Summary
Computes the string join along segments of a tensor. Given segment_ids
with rank N
and data
with rank N+M
:
`output[i, k1...kM] = strings.join([data[j1...jN, k1...kM])`
where the join is over all [j1...jN] such that segment_ids[j1...jN] = i. Strings are joined in row-major order.
For example:
inputs = [['Y', 'q', 'c'], ['Y', '6', '6'], ['p', 'G', 'a']] output_array = string_ops.unsorted_segment_join(inputs=inputs, segment_ids=[1, 0, 1], num_segments=2, separator=':')) # output_array ==> [['Y', '6', '6'], ['Y:p', 'q:G', 'c:a']]
inputs = ['this', 'is', 'a', 'test'] output_array = string_ops.unsorted_segment_join(inputs=inputs, segment_ids=[0, 0, 0, 0], num_segments=1, separator=':')) # output_array ==> ['this:is:a:test']
Arguments:
- scope: A Scope object
- inputs: The input to be joined.
- segment_ids: A tensor whose shape is a prefix of data.shape. Negative segment ids are not supported.
- num_segments: A scalar.
Optional attributes (see Attrs
):
- separator: The separator to use when joining.
Returns:
Output
: The output tensor.
