Django project structure and problem with imports

I use the following project structure. A project for me is all that PyCharm sees. Those. the project is not only django startproject but also all sorts of documentation files, docker-compose configs, etc. It looks like this:

 . (Папка проекта PyCharm) ├── env ├── site_proj (Сам проект Django) │  ├── chat_app │  │  ├── migrations │  │  ├── __pycache__ │  │  ├── templates │  │  ├── admin.py │  │  ├── apps.py │  │  ├── consumers.py │  │  ├── __init__.py │  │  ├── models.py │  │  ├── routing.py │  │  ├── tests.py │  │  ├── urls.py │  │  └── views.py │  ├── site_proj │  │  ├── __pycache__ │  │  ├── __init__.py │  │  ├── routing.py │  │  ├── settings.py │  │  ├── urls.py │  │  └── wsgi.py │  ├── db.sqlite3 │  └── manage.py ├── docker-compose.yml └── README.md 

Those. Everything related to the Django project lies in site_proj and does not interfere with files that do not belong to Django.

From here there are problems with import:

one)

 # ./site_proj/site_proj/routing.py from ..site_proj import chat_app 

ValueError: attempted relative import beyond top-level package

2)

 # ./site_proj/site_proj/routing.py from site_proj import chat_app # PyCharm autocomplete 

django.core.exceptions.ImproperlyConfigured: Cannot import ASGI_APPLICATION module 'site_proj.routing'

IDE:

3)

 # ./site_proj/site_proj/routing.py from site_proj.chat_app import routing 

django.core.exceptions.ImproperlyConfigured: Cannot import ASGI_APPLICATION module 'site_proj.routing'

If the root folder for the IDE is the Django project folder, then everything will be ok, but I don’t want to. What is the problem and how to solve it?
