pure virtual

Load the cost model from given file location.

Parameters

path	The file path.

Implemented in tvm::meta_schedule::PyCostModelNode.

Predict()

virtual std::vector<double> tvm::meta_schedule::CostModelNode::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.
