TargetTags

classsklearn.utils.TargetTags(required:bool, one_d_labels:bool=False, two_d_labels:bool=False, positive_only:bool=False, multi_output:bool=False, single_output:bool=True)[source]

Tags for the target data.

Parameters:

requiredbool

Whether the estimator requires y to be passed to fit, fit_predict or fit_transform methods. The tag is True for estimators inheriting from ~sklearn.base.RegressorMixin and ~sklearn.base.ClassifierMixin.

one_d_labelsbool, default=False

Whether the input is a 1D labels (y).

two_d_labelsbool, default=False

Whether the input is a 2D labels (y).

positive_onlybool, default=False

Whether the estimator requires a positive y (only applicable for regression).

multi_outputbool, default=False

Whether a regressor supports multi-target outputs or a classifier supports multi-class multi-output.

See multi-output in the glossary.

single_outputbool, default=True

Whether the target can be single-output. This can be False if the estimator supports only multi-output cases.
