Detailed Description

The base class for cost model.

Constructor & Destructor Documentation

◆ ~CostModelNode()

virtual tvm::auto_scheduler::CostModelNode::~CostModelNode ( )

inlinevirtual

Default virtual destructor.

Member Function Documentation

◆ Predict()

virtual void tvm::auto_scheduler::CostModelNode::Predict	(	const SearchTask &	task,
		const Array< State > &	states,
		std::vector< float > *	scores
	)

pure virtual

Predict the scores of states.

Parameters

task	The search task of states
states	The input states
scores	The predicted scores for all states

Implemented in tvm::auto_scheduler::PythonBasedModelNode, and tvm::auto_scheduler::RandomModelNode.

◆ PredictStages()

virtual void tvm::auto_scheduler::CostModelNode::PredictStages	(	const SearchTask &	task,

Parameters

task	The search task
states	The input states
state_scores	The predicted scores for all states
stage_scores	The predicted scores for all stages in all stages

Reimplemented in tvm::auto_scheduler::PythonBasedModelNode.

◆ TVM_DECLARE_BASE_OBJECT_INFO()
