django.core.exceptions.ImproperlyConfigured: WSGI application 'project.wsgi.application' could not be loaded; Error importing module.

I had a similar error too. On further debugging I realise that it was because I added an app to my installed app settings that was not in my virtual environment. To fix check do the following;

• That your environment variable is active.
• Run pip freeze > requirements.txt to see all your installed packages and ensure that the ones in your installed app settings are also in your requirements.txt file
