Add or change a related_name argument to the definition for 'auth.User.groups' or 'DriverUser.groups'. -Django ERROR, someone asked me to explain?

I got this following error while running the django project.

 SystemCheckError: System check identified some issues:
ERRORS:
auth.User.groups: (fields.E304) Reverse accessor 'Group.user_set' for 'auth.User.groups' clashes with reverse accessor for 'restaccount.DriverUser.groups'.

SOLUTION:

The following error indicates that the relation with model 'AUTH_USER_MODEL', which is not installed in settings.py.
Settings.py: Add the  'AUTH_USER_MODEL' 

AUTH_USER_MODEL = 'restaccount.DriverUser'
