[Python] SyntaxError: source code string cannot contain null bytes

I am trying to run python manage.py makemigrations and the below exception is being thrown.

please note that - 1 - I have my own User class in models.py 2 - Two model classes, one inside the app and other file outside the app. Outside models.py was generated class based on my db schema. I have used the below command to auto generate the file.

python manage.py inspectdb > models.py


Below is the error thrown upon running - python manage.py makemigrations
