SparseReduceSum

public final class SparseReduceSum

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 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.

Constant Value: "SparseReduceSum"

Public Methods

public Output<T> asOutput ()

Returns the symbolic handle of the tensor.

Inputs to TensorFlow operations are outputs of another TensorFlow operation. This method is used to obtain a symbolic handle that represents the computation of the input.

public static SparseReduceSum<T> create (Scope scope, Operand<TInt64> inputIndices, Operand<T> inputValues, Operand<TInt64> inputShape, Operand<TInt32> reductionAxes, Options... options)

Factory method to create a class wrapping a new SparseReduceSum operation.

Parameters

scope	current scope
inputIndices	2-D. `N x R` matrix with the indices of non-empty values in a SparseTensor, possibly not in canonical ordering.
inputValues	1-D. `N` non-empty values corresponding to `input_indices`.
inputShape	1-D. Shape of the input SparseTensor.
reductionAxes	1-D. Length-`K` vector containing the reduction axes.
options	carries optional attributes values

Returns

a new instance of SparseReduceSum

public static SparseReduceSum.Options keepDims (Boolean keepDims)

Parameters

keepDims	If true, retain reduced dimensions with length 1.

public Output<T> output ()

`R-K`-D. The reduced Tensor.
