Member Typedef Documentation

◆ FClone

using tvm::meta_schedule::PySearchStrategyNode::FClone = SearchStrategy::FClone

◆ FGenerateMeasureCandidates

using tvm::meta_schedule::PySearchStrategyNode::FGenerateMeasureCandidates = SearchStrategy::FGenerateMeasureCandidates

◆ FInitializeWithTuneContext

using tvm::meta_schedule::PySearchStrategyNode::FInitializeWithTuneContext = SearchStrategy::FInitializeWithTuneContext

◆ FNotifyRunnerResults

using tvm::meta_schedule::PySearchStrategyNode::FNotifyRunnerResults = SearchStrategy::FNotifyRunnerResults

◆ FPostTuning

using tvm::meta_schedule::PySearchStrategyNode::FPostTuning = SearchStrategy::FPostTuning

◆ FPreTuning

Member Function Documentation

◆ Clone()

SearchStrategy tvm::meta_schedule::PySearchStrategyNode::Clone ( ) const

finalvirtual

Clone the search strategy.

Returns: The cloned search strategy.

Implements tvm::meta_schedule::SearchStrategyNode.

◆ GenerateMeasureCandidates()

ffi::Optional<ffi::Array<MeasureCandidate> > tvm::meta_schedule::PySearchStrategyNode::GenerateMeasureCandidates ( )

finalvirtual

Generate measure candidates from design spaces for measurement.

Returns: The measure candidates generated, nullptr if finished.

Implements tvm::meta_schedule::SearchStrategyNode.

◆ InitializeWithTuneContext()

void tvm::meta_schedule::PySearchStrategyNode::InitializeWithTuneContext ( const TuneContext & context )

finalvirtual

Initialize the search strategy with tuning context.

Parameters

context The tuning context for initialization.

Note: This method is supposed to be called only once before every other method.

Implements tvm::meta_schedule::SearchStrategyNode.

◆ NotifyRunnerResults()

void tvm::meta_schedule::PySearchStrategyNode::NotifyRunnerResults	(	const ffi::Array< MeasureCandidate > &	measure_candidates,
		const ffi::Array< RunnerResult > &	results
	)

virtual

Update the search strategy with measurement results.

Parameters

measure_candidates	The candidates to be measured.
results	The measurement results from the runner.

Implements tvm::meta_schedule::SearchStrategyNode.

◆ PostTuning()

void tvm::meta_schedule::PySearchStrategyNode::PostTuning ( )

finalvirtual

Post-tuning for the search strategy.

Note: Post-tuning is supposed to be called after the tuning process and before we reset the search strategy with another pre-tuning. Post-tuning can be empty.

Implements tvm::meta_schedule::SearchStrategyNode.

◆ PreTuning()

void tvm::meta_schedule::PySearchStrategyNode::PreTuning	(	int	max_trials,
		int	num_trials_per_iter,
		const ffi::Array< tir::Schedule > &	design_spaces,
		const ffi::Optional< Database > &	database,
		const ffi::Optional< CostModel > &	cost_model
	)

finalvirtual

Pre-tuning for the search strategy.

Parameters

max_trials	The maximum number of trials.
num_trials_per_iter	The number of trials per iteration.
design_spaces	The design spaces used during tuning process.
database	The database used during tuning process.
cost_model	The cost model used during tuning process.

Note: Pre-tuning is supposed to be called before the tuning process and after the initialization. Because the search strategy is stateful, we can always call pretuning and reset the search strategy.

Implements tvm::meta_schedule::SearchStrategyNode.

◆ RegisterReflection()

static void tvm::meta_schedule::PySearchStrategyNode::RegisterReflection ( )

inlinestatic

◆ TVM_FFI_DECLARE_OBJECT_INFO_FINAL()

tvm::meta_schedule::PySearchStrategyNode::TVM_FFI_DECLARE_OBJECT_INFO_FINAL	(	"meta_schedule.PySearchStrategy"	,
		PySearchStrategyNode	,
		SearchStrategyNode
	)
