That PR actually only tested simple_test and advanced_test notebooks. Could you add any other that are ready to be tested to test_notebooks.py in PyGEM-Community/PyGEM#78?

Yes, done. Thanks for pointing that out.

@ddundo if you want to review this - the three main test notebooks we currently have setup simple_test, advanced_test, and advanced_test_tw all now run with the updated configuration management setup. This is good to pull to dev for now. We can add more notebooks down the road.
