I mean, sqlalchemy until very recently needed a mypy plugin to type correctly (https://docs.sqlalchemy.org/en/20/orm/extensions/mypy.html https://docs.sqlalchemy.org/en/20/orm/extensions/mypy.html), which was just deprecated in 2.0.0. Perhaps you should do the upgrade (https://docs.sqlalchemy.org/en/20/changelog/whatsnew_20.html#orm-declarative-models https://docs.sqlalchemy.org/en/20/changelog/whatsnew_20.html...) and try again?
