I encountered a ModuleNotFoundError when attempting to import my MongoDB configuration from config.py into my routes.py file located in the routers folder. Here’s the import statement causing the issue:

`from app.config import db ModuleNotFoundError: No module named 'app'`

app
├── config.py
├── Dockerfile
├── __init__.py
├── main.py
├── models
│   ├── __init__.py
│   └── Models.py
├── routers
│   ├── datas.py
│   ├── __init__.py
│   └── users.py
└── schemas
    ├── dicto.py
    ├── __init__.py
    └── states.py

I run the project from app dir and also tried this import method:
from ..config import db
