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

Generate design spaces given a module.

Parameters
modThe 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
contextThe 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_DECLARE_BASE_OBJECT_INFO()

tvm::meta_schedule::SpaceGeneratorNode::TVM_DECLARE_BASE_OBJECT_INFO ( SpaceGeneratorNode  ,
Object   
)

Member Data Documentation

◆ mutator_probs

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

The probability of using certain mutator.

◆ postprocs

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

The postprocessors.

◆ sch_rules

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

The schedule rules.
