No module named 'db_file_storage.urls'

[nulls3c]

Description

I'm sure this is an issue on my end but I can't figure out why Django is throwing an ImportError for _db_filestorage.urls within my application's main urlpatterns (MyApp/urls.py). I've followed the configuration setup from here https://django-db-file-storage.readthedocs.io/en/master/ and I have the rest of the setup complete, I just can't seem to get past this Import issue.

When testing using the Django shell from CLI I am able to import 'db_file_storage.urls' fine and inspect the object. It's only when accessing the application from the browser does the Import fail to resolve and throws an error. I also tested importing _db_filestorage at the top of my urls.py which was successful. Any attempts to include urls from _db_filestorage resulted in the same Import error.

Environment

Django 2.0.1 Python 3.4.9 (Virtual Environment) Apache 2.4.6 (CentOS)
