Im trying to generate the model or a mysql database using sqlacodegen mysql://username:password@127.0.0.1:3307/mydb > models.py and getting an error

AttributeError: module 'sqlalchemy' has no attribute '__all__'. Did you mean: '__file__'?

How can I fix this? I've been trying different sqlalchemy versions with no luck

Have you tried updating your sqlacodegen to the latest pre-release version?
