Nettet12. des. 2024 · SelectFromModel expects an estimator having coef_ (check LinearSVC once fitted) or feature_importances_ (check DecisionTreeClassifier). XGBoostClassifier is (probably) not implementing this functionality. NettetFor “one-vs-rest” LinearSVC the attributes coef_ and intercept_ have the shape (n_classes, n_features) and (n_classes,) respectively. Each row of the coefficients corresponds to one of the n_classes “one-vs-rest” classifiers and similar for the intercepts, in the order of the “one” class.
