Demo does not work

[chrisspen]

Running the demo with python -m demo.qa seems to correctly launch the Flask web server, but the demo itself doesn't actually do anything. The page renders, and the "Get new story" button cycles through random stories, but the "Predict answer" button does nothing, and no memory or answers are ever shown.

This is what I see when I view the web app.

The console shows these errors:
