Error

As of Scikit-Learn 1.2+ the method sklearn.metrics.plot_roc_curve is deprecated in favour of sklearn.metrics.RocCurveDisplay.

How to check your Scikit-Learn version

You can check your Scikit-Learn version with:

import sklearn
sklearn.__version__

How to update your Scikit-Learn version

You can run the following command in your terminal with your Conda (or other) environment active to upgrade Scikit-Learn (the -U stands for "upgrade):

pip install -U scikit-learn

Previous code (this will error if running Scikit-Learn version 1.2+)

# This will error if run in Scikit-Learn version 1.2+
from sklearn.metrics import plot_roc_curve

Also:

# This will error if run in Scikit-Learn version 1.2+
from sklearn.metrics import plot_roc_curve 
plot_roc_curve(gs_log_reg, X_test, y_test);

New code (this will work with Scikit-Learn version 1.2+)

from sklearn.metrics import RocCurveDisplay # new in Scikit-Learn 1.2+

And to plot a ROC curve, note the use of RocCurveDisplay.from_estimator():

# Scikit-Learn 1.2.0 or later
from sklearn.metrics import RocCurveDisplay 

# from_estimator() = use a model to plot ROC curve on data
RocCurveDisplay.from_estimator(estimator=gs_log_reg, 
                               X=X_test, 
                               y=y_test);
