Constructor & Destructor Documentation

◆ ~SpaceGeneratorNode()

virtual tvm::meta_schedule::SpaceGeneratorNode::~SpaceGeneratorNode ( )

virtualdefault

Default destructor.

Member Function Documentation

◆ Clone()

virtual SpaceGenerator tvm::meta_schedule::SpaceGeneratorNode::Clone ( ) const

pure virtual

Clone the space generator.

Returns: The cloned space generator.

Implemented in tvm::meta_schedule::PySpaceGeneratorNode.

◆ GenerateDesignSpace()

virtual ffi::Array<tir::Schedule> tvm::meta_schedule::SpaceGeneratorNode::GenerateDesignSpace ( const IRModule & mod )

pure virtual

Generate design spaces given a module.

Parameters

mod	The module used for design space generation.

Returns: The generated design spaces, i.e., schedules.

Implemented in tvm::meta_schedule::PySpaceGeneratorNode.

◆ InitializeWithTuneContext()

virtual void tvm::meta_schedule::SpaceGeneratorNode::InitializeWithTuneContext ( const TuneContext & context )

virtual

Initialize the design space generator with tuning context.

Parameters

context The tuning context for initialization.

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

Reimplemented in tvm::meta_schedule::PySpaceGeneratorNode.

◆ RegisterReflection()

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

inlinestatic

◆ TVM_FFI_DECLARE_OBJECT_INFO()

tvm::meta_schedule::SpaceGeneratorNode::TVM_FFI_DECLARE_OBJECT_INFO	(	"meta_schedule.SpaceGenerator"	,
		SpaceGeneratorNode	,
		Object
	)

Member Data Documentation

◆ _type_mutable

constexpr const bool tvm::meta_schedule::SpaceGeneratorNode::_type_mutable = true

staticconstexpr

◆ mutator_probs

ffi::Optional<ffi::Map<Mutator, FloatImm> > tvm::meta_schedule::SpaceGeneratorNode::mutator_probs

The probability of using certain mutator.

◆ postprocs

ffi::Optional<ffi::Array<Postproc> > tvm::meta_schedule::SpaceGeneratorNode::postprocs

The postprocessors.

◆ sch_rules

ffi::Optional<ffi::Array<ScheduleRule> > tvm::meta_schedule::SpaceGeneratorNode::sch_rules

The schedule rules.
