tensorflow::ops::SparseReduceSum

#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 particular, this Op also returns a dense Tensor instead of a sparse one.

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.

Arguments:

  • 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.

Returns:
