ImportError when trying to embed a Bokeh section next to the Django download button

I am trying to embed a Bokeh plot in a Django site that has a download button on it. I use the example here here as a starting point, and then adding the implementation instructions from here , I used it need-a-minimal-django-file-upload-example/for_django_1.8, and it works as intended. Then I changed the following files, but I get the following error:

ImportError: no module named 'myapp'

Here you can see my directory structure and three files modified / added:

If you cannot upload the image, here:
