Broken pipe when using sqlalchemy

We're attempting to migrate away from the mysqldb connector to mariadb with sqlalchemy. When populating our tables with initial data we consistently get a "mariadb.OperationalError: Write error: Broken pipe (32)" exception (the mysqldb connector worked fine). Increasing the max_allowed_packet seems to help a bit, but we don't make it through our entire dataset. Are there any other options/arguments that may help here? Thanks!
