Detailed Description

MatcherPass is a basic block for pattern based transformations. It describes pattern and action that is applied if pattern is matched.

MatcherPass consists of Matcher and matcher_pass_callback that needs to be implemented and finally registered by using

See also: register_matcher. MatcherPass can be executed on node within; apply method. To run matcher pass on Function use GraphRewrite. In addition MatcherPass provides a way for adding new operations into GraphRewrite execution queue. That means that operations that were created inside transformation callback can be added for matching. To register node use; register_new_node method. GraphRewrite automatically takes registered nodes and put them to execution queue. If multiple nodes were register make sure that they were registered in topological order. Note: when implementing pattern for Matcher make sure that root node is an operation from opset or has ngraph::pattern::op::WrapType. That will help GraphRewrite to execute matcher passes more efficient.

The documentation for this class was generated from the following file:
