Usually, this error means there is an error in the Django project somewhere. It could be hard to locate.

You can try multiple solutions like: 1. Restart Apache 2. Execute makemigrations and migrate Django commands 3. Modify your wsgi.py file so you can manage the exception

A little note, in the line File "/home/abhadran/myenv/lib/python3.6/site-packages/django/apps/registry.py" indicate that you're using Python 3.6 and not Python 3.5 as you mentioned in your description.

Python 3.6 is officially supported until Django 1.11, so you maybe must upgrade your Django version or downgrade your Python in your venv.
