sklearn.feature_selection.mutual_info_classif(X, y, 
                                              discrete_features='auto', 
                                              n_neighbors=3,

                                             )

X :特征矩阵

y :目标向量

discrete_features : {‘auto’, bool, array_like}, default ‘auto’
