catboost: Exception when CatBoostRegressor is disposed

If I create a CatBoostRegressor instance in a script, then when the script tears down CatBoostRegressor throws an exception

i.e. save the following in a script then run it from the console

from catboost import CatBoostRegressor
estimator = CatBoostRegressor(loss_function='RMSE', has_time=True, logging_level='Silent', task_type='GPU', devices='0')

TypeError: ‘NoneType’ object is not callable Exception ignored in: ‘_catboost._CatBoost.dealloc’ TypeError: ‘NoneType’ object is not callable

catboost version: catboost==0.11.2
