IBM db2 — миграция перегонного куба ⇐ Python

Я пытаюсь бежать
alembic upgrade head

в моей базе данных IBM Cloud DB2 lite, но получаю
KeyError: ibm_db_sa

В моем .venv уже установлены пакеты ibm_db, ibm_db_sa и ibm_db_alembi, и URL-адрес соединения работает при подключении к БД через sqlalchemy (создание движка/сессии). Подробное описание ошибок приведено ниже.
