Re: [Scikit-learn-general] Restrictions on feature names when drawing decision tree

The code snippet should have been reg = DecisionTreeRegressor(max_depth=None,min_samples_split=1) reg.fit(X,Y) scores = cross_val_score(reg, X, Y) print scores dot_data = StringIO() tree.export_graphviz(reg, out_file=dot_data, feature_names=feature_names,
