I got it working by installing a completely updated set of packages, as see below.
The demo runs and I can change in the figure data dictionary in the app.py source code file and see the updates to the graphs as a result of the react.js components.

functools is not available yet for Python 3.7 or at least I could not figure out how to install just that package in my environment using pip. Only the 32-bit functools was available; it gives the error down at the bottom of this posting.
