Function Documentation

◆ AsTensor()

template<typename T , typename U >

RTensor< T > TMVA::Experimental::AsTensor	(	U &	dataframe,
		std::vector< std::string >	columns = `{}`,
		MemoryLayout	layout = `MemoryLayout::RowMajor`
	)

Convert the content of an RDataFrame to an RTensor.

Parameters

[in]	dataframe	RDataFrame node
[in]	columns	Vector of column names
[in]	layout	Memory layout

Returns: RTensor with content from selected columns

Definition at line 21 of file RTensorUtils.hxx.

◆ Compute()

template<std::size_t N, typename T , typename F >

auto TMVA::Experimental::Compute ( F && f ) -> Internal::ComputeHelper<std::make_index_sequence<N>, T, F>

Helper to pass TMVA model to RDataFrame.Define nodes.

Definition at line 32 of file RInferenceUtils.hxx.

◆ operator<<()

template<typename T >

std::ostream & TMVA::Experimental::operator<<	(	std::ostream &	os,
		RTensor< T > &	x
	)

Pretty printing.

Parameters

[in]	os	Output stream
[in]	x	RTensor

Returns: Modified output stream

Definition at line 582 of file RTensor.hxx.

◆ SofieFunctor()

template<std::size_t N, typename Session_t >

auto TMVA::Experimental::SofieFunctor	(	unsigned int	nslots = `0`,
		const std::string &	weightsFile = `""`
	)		-> SofieFunctorHelper<std::make_index_sequence<N>, Session_t, float>

SofieFunctor : used to wrap the infer function of the generated model by SOFIE in a RDF compatible signature.

The number of slots is an optional parameter used to create multiple SOFIE Sessions, which can be run in a parallel model evaluation. One shouild use as number of slots the number of slots used by RDataFrame. By default, in case of nslots=0, only a single Session will be created and the Functor cannot be run in parallel. Examples of using the SofieFunctor are the C++ tutorial TMVA_SOFIE_RDataFrame.C and the Python tutorial TMVA_SOFIE_RDataFrame.py which makes use of the ROOT JIT to compile on the fly the generated SOFIE model.
