MovedIn20Warning: The declarative_base() function is now available as sqlalchemy.orm.declarative_base(). (deprecated since: 1.4) (Background on SQLAlchemy 2.0 at: https://sqlalche.me/e/b8d9)
Base = declarative_base()
mbdata's requirements.txt does not specify any fixed SQLAlchemy version so we need to account for versions before 1.4 as well where this import does not exist.
