I have a flask application. My project tree looks like:
.
├── Procfile
├── README.md
├── alembic
├── alembic.ini
├── my_app
├── requirements.txt
├── start_server.py
└── venv
Where my_app contains Flask application, for some reason *branches* command
fails to run with an error ImportError: No module named my_app.types
Traceback (most recent call last):

Other commands like upgrade or revision --autogenerate work fine.
