SparseReduceSumSparse

public final class SparseReduceSumSparse

Computes the sum of elements across dimensions of a SparseTensor.

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.

reductionAxes 1-D. Length-`K` vector containing the reduction axes.
options carries optional attributes values
Returns
  • a new instance of SparseReduceSumSparse

public static SparseReduceSumSparse.Options keepDims (Boolean keepDims)

Parameters
