I was trying to calculate the Permutation Importance by using Eli5, however the command eli5.show_weights does not fetch any image or anything. (I tried in Python 2.7 and 3.7.) Code snippet: feature_names = [c for c in train_df.columns if train_df[c].dtype in [np.int64]] X = train_df[feature_names] X = X.drop('state', axis=1) y = train_df['state'] X_train, X_test, y_train, y_test = train_test_split(X, y, random_state=1) my_model = RandomForestClassifier(n_estimators=100, random_state=1).fit(X_train, y_train) perm = PermutationImportance(my_model, random_state=1).fit(X_test, y_test) eli5.show_weights(perm, show_feature_values = X_test.columns.tolist()) The last line prints nothing.
