Parameters ---------- name_or_id : int or str The integer id or the string name metadata of the MLComp dataset to load set\_ : str, default='raw' Select the portion to load: 'train', 'test' or 'raw' mlcomp_root : str, optional The filesystem path to the root folder where MLComp datasets are stored, if mlcomp_root is None, the MLCOMP_DATASETS_HOME environment variable is looked up instead. **kwargs : domain specific kwargs to be passed to the dataset loader. Returns ------- data : Bunch Dictionary-like object, the interesting attributes are: 'filenames', the files holding the raw to learn, 'target', the classification labels (integer index), 'target_names', the meaning of the labels, and 'DESCR', the full description of the dataset. Note on the lookup process: depending on the type of name_or_id, will choose between integer id lookup or metadata name lookup by looking at the unzipped archives and metadata file.
