ImportError: No module named models?

I am using Django and I keep receiving this error for my group app, I have checked all my import settings and everything is fine. My registration and profile apps run smoothly but why is this app giving me an ImportError for models?

Traceback (most recent call last):

Because it thinks that you're referring to the groups.py in the same directory. Enable absolute imports.

I hade the same problem. The solution was as simple as

from __future__ import absolute_import

hinted by Ignacio

Just a guess, but does your models.py file import groups or decorators? If so, you have a circular dependency. You'll need to move the imports in one of the files into the function level.
