Computes tf.sparse.add
of elements across dimensions of a SparseTensor.
tf.sparse.reduce_sum(
sp_input, axis=None, keepdims=None, output_is_sparse=False, name=None
)
This is the reduction operation for the elementwise tf.sparse.add
op.
This Op takes a SparseTensor and is the sparse counterpart to
tf.reduce_sum()
. In particular, this Op also returns a dense Tensor
if output_is_sparse
is False
, or a SparseTensor
if output_is_sparse
is True
.
Reduces sp_input
along the dimensions given in axis
. Unless keepdims
is
true, the rank of the tensor is reduced by 1 for each entry in axis
. If
keepdims
is true, the reduced dimensions are retained with length 1.
If axis
has no entries, all dimensions are reduced, and a tensor
with a single element is returned. Additionally, the axes can be negative,
similar to the indexing rules in Python.
