Detailed Documentation

Operation which “adds” axes to an input tensor, replicating elements from the input as needed along the new axes.

Construction

Broadcast()

Constructs a broadcast operation.

Broadcast(
    const Output<Node>& arg,
    const Output<Node>& target_shape,
    const Output<Node>& axes_mapping,
    const BroadcastModeSpec& broadcast_spec = BroadcastType::EXPLICIT
    )

Constructs a broadcast operation.

Parameters:

arg

The input tensor to be broadcast.

target_shape

The shape of the output tensor.

axes_mapping

The axis positions (0-based) in the result that correspond to input axes. ‘Arg’ tensor is broadcast along the remaining axes. E.g., Input Shape - [3, 4], Target Shape - [3, 5, 4, 4] axes_mapping - [0, 2] => Broadcast along axes 1 and 3. axes_mapping - [0, 3] => Broadcast along axes 1 and 2.

broadcast_spec

Broadcast specification to use for determining broadcast axes. ‘axes_mapping’ should not be provided if mode other than explicit (none) is used.

Broadcast(
    const Output<Node>& arg,
    const Output<Node>& target_shape,
    const BroadcastModeSpec& broadcast_spec = BroadcastType::NUMPY
    )

Constructs a broadcast operation.

Parameters:

arg

The input tensor to be broadcast.

target_shape

The shape of the output tensor.

broadcast_spec

Broadcast specification to use for determining broadcast axes

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 std::pair<bool, AxisSet> get_broadcast_axes() const

Returns:

true and the AxisSet if broadcast axes can be fully determined.

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.
