Detailed Description

template<typename V>
class ngraph::Evaluator< V >

Execute handlers on a subgraph to compute values.

Member Typedef Documentation

◆ op_handler

template<typename V >

using ngraph::Evaluator< V >::op_handler = std::function<std::vector<V>(Node* op, std::vector<V>& inputs)>

Handler for a computation of a value about an op.

A handler is passed a Node* and a vector of computed input values. The handler should return a vector of computed output values.

Constructor & Destructor Documentation

◆ Evaluator()

template<typename V >

ngraph::Evaluator< V >::Evaluator	(	const op_handler_map &	handlers,
		value_map &	values
	)

inline

construct handler using the provided op handlers.

Evaluations share previously computed values so that calls on multiple nodes can share work. All state is kept in the value map, which is accessible for clearing or seeding with Evaluator::get_value_map().

Parameters

Handlers for ops. Pairs of Node::type_info_t and handler functions.
