Detailed Documentation

Tensor sum operation.

Element-wise sums the input tensor, eliminating the specified reduction axes. For example:

\[\begin{split}\mathit{sum}\left(\{0\}, \left[ \begin{array}{ccc} 1 & 2 \\ 3 & 4 \\ 5 & 6 \end{array} \right]\right) = \left[ (1 + 3 + 5), (2 + 4 + 6) \right] = \left[ 9, 12 \right]~~~\text{(dimension 0 (rows) is eliminated)}\end{split}\]

\[\begin{split}\mathit{sum}\left(\{1\}, \left[ \begin{array}{ccc} 1 & 2 \\ 3 & 4 \\ 5 & 6 \end{array} \right]\right) = \left[ (1 + 2), (3 + 4), (5 + 6) \right] = \left[ 3, 7, 11 \right]~~~\text{(dimension 1 (columns) is eliminated)}\end{split}\]

\[\begin{split}\mathit{sum}\left(\{0,1\}, \left[ \begin{array}{ccc} 1 & 2 \\ 3 & 4 \\ 5 & 6 \end{array} \right]\right) = (1 + 2) + (3 + 4) + (5 + 6) = 21~~~\text{(both dimensions (rows and columns) are eliminated)}\end{split}\]

Parameters

	Description
reduction_axes	The axes to eliminate through summation.
keep_dims	If set to 1 it holds axes that are used for reduction.

Inputs

	Type	Description
arg	\(N[d_1,\dots,d_n]~(n \geq 0)\)	An input tensor of any shape and numeric element type.

Type	Description
\(N[\textit{delete}(A,d_1,\dots,d_n)]\)	The tensor \(T\) , where \(T\) is the input tensor with the reduction_axes \(A\) eliminated by summation.

Construction

ReduceSum()

Constructs a summation operation.

ReduceSum(
    const Output<Node>& arg,
    const Output<Node>& reduction_axes,
    bool keep_dims = false
    )

Constructs a summation operation.

Parameters:

arg	The tensor to be summed.
reduction_axes	The axis positions (0-based) to be eliminated.
keep_dims	If set to 1 it holds axes that are used for reduction.

Methods

virtual OPENVINO_SUPPRESS_DEPRECATED_START std::shared_ptr<Node> get_default_value() const

Returns:

The default value for Sum.

virtual OPENVINO_SUPPRESS_DEPRECATED_END OPENVINO_SUPPRESS_DEPRECATED_START bool evaluate(
    const HostTensorVector& output_values,
    const HostTensorVector& input_values
    ) const

Evaluates the op on input_values putting results in output_values.

Deprecated Use evaluate with ov::Tensor instead

Parameters:

output_values	Tensors for the outputs to compute. One for each result
input_values	Tensors for the inputs. One for each inputs.

Returns:

true if successful

virtual OPENVINO_SUPPRESS_DEPRECATED_END bool has_evaluate() const

Allows to get information about availability of evaluate method for the current operation.
