pycharm unable to load django apps

Question

In The PyCharm I have Django configured in virtual environment , what I did is:

1. Previously I had python 3.6 on my windows 10 so I uninstalled it and
2. Installed Python 3.7
3. pip install virtualenv
4. vertualenv venv and then activated it
5. pip install django
6. also installed djangorestframework , coreapi and requests via pip
7. django-admin startproject hasslefreeaccounts
8. opened project in PyCharm, then: Files > settings > Language & Framework and Configured my project as:
9. entered project root, settings.py and manage.py path (see image below)

and then created 2 apps named customer and master
and then configured the run configurations as:

after this (am using pycharm professional) everything works fine except while importing apps PyCharm Gives me error when I import my django apps in other as:

from masters.models import some_class

pycharm says cant find module, thought when I run project it works fine with no error.
so I tried doing:

from ..master.models import some_class

This makes PyCharm import apps (see image below)

this in pycharm doesn't shows any error but on run gives error as:

ValueError: attempted relative import beyond top-level package

Other Details:

and here is the project interpreter settings :

and Settings.py as:

UPDATED:

Basically PyCharm is reading my apps one directory above
I have tried updating my project source root to one directory above as well, but that doesn't help, in project interpreter settings

Answer 1

Not sure of but this helped me!

As in the image shown, the virtualenv shall be within the project directory and not outside, this helpe me!
