RuntimeError: The runtime optuna version 1.2.0 is no longer compatible with the table schema (set up by optuna 0.10.0)

[viper7882]

The fix to this error for me is to downgrade optuna to 0.10.00: pip install optuna==0.10.0

or just update the db: optuna storage upgrade --storage sqlite:///data/params.db
