Plot_roc_curve(test_labels, predictions), you will get an image like the following, and a print out with the auc score and the roc curve python plot:. Selecting the values in columns h and i and drawing them as a scatter plot, we can get the roc curve as shown below. At last, we calculate the roc auc score for the model through roc () method and plot the same using plot () function available in the ‘ proc ’ library.
