Greetings!
It seems that the GitHub rendering of the notebook may be having problems. Try
using this link and saving the page as a "QGAnalysis.ipynb" and then opening it:
https://gist.githubusercontent.com/dcamron/84dee25ab2ce81b24624e919186df581/raw/8a08a038e6968fdabaf192199201d6f516f8aaaf/QG%2520Analysis.ipynb
