Computes the sum of elements across dimensions of a SparseTensor.
tf.raw_ops.SparseReduceSum( input_indices, input_values, input_shape, reduction_axes, keep_dims=False, name=None )
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.
Args | |
---|---|
input_indices | A Tensor of type int64 . 2-D. N x R matrix with the indices of non-empty values in a SparseTensor, possibly not in canonical ordering. |
input_values | A Tensor . Must be one of the following types: float32 , float64 , int32 , uint8 , int16 , int8 , complex64 , int64 , qint8 , quint8 , qint32 , bfloat16 , uint16 , complex128 , half , uint32 , uint64 . 1-D. N non-empty values corresponding to input_indices . |
input_shape | A Tensor of type int64 . 1-D. Shape of the input SparseTensor. |
reduction_axes | A Tensor of type int32 . 1-D. Length-K vector containing the reduction axes. |
keep_dims | An optional bool . Defaults to False . If true, retain reduced dimensions with length 1. |
name | A name for the operation (optional). |
Returns | |
---|---|
A Tensor . Has the same type as input_values . |
