Detailed Documentation

Splits the input tensor into a list of equal sized tensors.

Construction

Split()

Constructs a split operation.

Split(
    const Output<Node>& data,
    const Output<Node>& axis,
    const size_t num_splits
    )

Constructs a split operation.

Parameters:

data	The tensor to be split.
axis	The index of an axis in “data” along which to perform the split.
num_splits	The number of pieces that the data tensor should be split into.

Methods

virtual void validate_and_infer_types()

Verifies that attributes and inputs are consistent and computes output shapes and element types. Must be implemented by concrete child classes so that it can be run any number of times.

Throws if the node is invalid.

virtual 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.
