/opt/conda/envs/python3new/lib/python3.6/site-packages/sqlalchemy/dialects/mysql/base.py:1740: SAWarning: MariaDB (10, 2, 6) before 10.2.9 has known issues regarding CHECK constraints, which impact handling of NULL values with SQLAlchemy's boolean datatype (MDEV-13596). An additional issue prevents proper migrations of columns with CHECK constraints (MDEV-11114). Please upgrade to MariaDB 10.2.9 or greater, or use the MariaDB 10.1 series, to avoid these issues.
