Member Function Documentation

Load()

virtual void tvm::s_tir::meta_schedule::CostModelObj::Load ( const ffi::String &  path )

pure virtual

Load the cost model from given file location.

Parameters

path	The file path.

Implemented in tvm::s_tir::meta_schedule::PyCostModelObj.

Predict()

virtual std::vector< double > tvm::s_tir::meta_schedule::CostModelObj::Predict ( const TuneContext &  context, const ffi::Array< MeasureCandidate > &  candidates  )

pure virtual

Predict the normalized score (the larger the better) of given measure candidates.

Parameters

context	The tuning context.
candidates	The measure candidates.

Returns

The predicted normalized score.

Implemented in tvm::s_tir::meta_schedule::PyCostModelObj.

Save()

virtual void tvm::s_tir::meta_schedule::CostModelObj::Save ( const ffi::String &  path )

pure virtual
