class dgl.data.chem.ConcatFeaturizer(**kwargs)[source]

Concatenate the evaluation results of multiple functions as a single feature.

Parameters:func_list (list) – List of functions for computing molecular descriptors from objects of a same particular data type, e.g. rdkit.Chem.rdchem.Atom. Each function is of signature func(data_type) -> list of float or bool or int. The resulting order of the features will follow that of the functions in the list.
