tensorflow::ops::SparseConcat
#include <sparse_ops.h>
Concatenates a list of SparseTensor
along the specified dimension.
Summary
Concatenation is with respect to the dense versions of these sparse tensors. It is assumed that each input is a SparseTensor
whose elements are ordered along increasing dimension number.
All inputs' shapes must match, except for the concat dimension. The indices
, values
, and shapes
lists must have the same length.
The output shape is identical to the inputs', except along the concat dimension, where it is the sum of the inputs' sizes along that dimension.
The output elements will be resorted to preserve the sort order along increasing dimension number.
