Ah, therein lies the rub? So the Jupyter Notebook is using Python 2.x not 3.x? I thought it was strange when I could replace print() with print! How do I setup the Jupyter Notebook so it switches to Jupyter 3.x? This us what happens when you depend in a cloud service rather than installing everything yourself on your own Linux Box as I would usually do.
