title: Trying to get Jupyter Notebook 5.1 Running (keeps running 4.2.1)
body: <p>I did a "pip3 install --upgrade notebook" to get the latest version of Jupyter notebook (5.1.0).  The installation went fine, but when I launch "jupyter notebook" from the terminal and then go into "help>about" it is still running 4.2.1  Can someone tell me how to launch the new version?</p>
