I'm trying to embed a Bokeh plot into a Django site that has an upload button. I'm using the example given here as a starting point and then adding on the instructions on embedding from here. I used need-a-minimal-django-file-upload-example/for_django_1.8 and it works as intended. I've then modified the following files, but I get the following error:
ImportError: No module named 'myapp'
You can see my directory structure here and the three files modified/added:
