Getting error fit() got an unexpected keyword argument 'callbacks' while running catboost_pruning.py

Hello

I've been trying to run catboost_pruning.py, but I got this error immediately.

Any help would be appreciated

Environment

• Optuna version: 2.10.0
• Catboost version: 0.25.1
• Python version: 3.6.9

I updated Optuna to 1.0.4, and the error is gone.
