It occurred to me that the "print("AUC: ", roc_auc_score(y_test, y_pred_prob)" in section 13 doesn't have LogisticRegression predict_proba. The only other "y_pred_prob" is in section 11, and the line is y_pred_prob = nb.predict_proba(X_test_dtm)[:, 1], which is the Multinomial Naive Bayes predict_proba in Section 11.
"y_pred_proba = logreg.predict_proba(X_test_dtm)[:, 1] # Get probability for class 1\n",
