Just want to share another option:

# mark two objects to be deleted
session.delete(obj1)
session.delete(obj2)

session.commit()

http://docs.sqlalchemy.org/en/latest/orm/session_basics.html#deleting

In this example, the following codes shall works fine:

obj = User.query.filter_by(id=123).one()
session.delete(obj)
session.commit()
