SparseReduceSumSparse
#include <sparse_ops.h>
Computes the sum of elements across dimensions of a SparseTensor.
Summary
This Op takes a SparseTensor and is the sparse counterpart to
tf.reduce_sum()
. In contrast to
SparseReduceSum
, this Op returns a SparseTensor.
Reduces
sp_input
along the dimensions given in
reduction_axes
. Unless
keep_dims
is true, the rank of the tensor is reduced by 1 for each entry in
reduction_axes
. If
keep_dims
is true, the reduced dimensions are retained with length 1.
If
reduction_axes
has no entries, all dimensions are reduced, and a tensor with a single element is returned. Additionally, the axes can be negative, which are interpreted according to the indexing rules in Python.
Args:
-
scope: A
Scope
object
-
input_indices: 2-D.
N x R
matrix with the indices of non-empty values in a SparseTensor, possibly not in canonical ordering.
-
input_values: 1-D.
N
non-empty values corresponding to
input_indices
.
-
input_shape: 1-D. Shape of the input SparseTensor.
-
reduction_axes: 1-D. Length-
K
vector containing the reduction axes.
Optional attributes (see
Attrs
):
-
keep_dims: If true, retain reduced dimensions with length 1.
