Error when deploying to Heroku

[taylor-smith]

Hi there,

I'm following the steps to deploy to Heroku. It seems to get through most of the setup just fine, and then at the very end when it is actually deploying to Heroku, I encounter the following error:

Traceback (most recent call last):
File "manage.py", line 3, in
from retro import create_app, db
File "/app/retro/init.py", line 19, in
from . import views, errors
File "/app/retro/views.py", line 6, in
from models import Sprint, RetrospectiveItem
ModuleNotFoundError: No module named 'models'

Any idea what might be going on?
