TypeError: cannot pickle 'Environment' object

Hi, I use python 3.12.2 and torch 2.2.2 on macOS 12.7.4.
The ReFinED version is 1.0.
When trying fine-tuning the following error happened.
( python src/refined/training/fine_tune/fine_tune.py --experiment_name test )

```TypeError: cannot pickle 'Environment' object```

Could you tell me what could be done to workaround this issue?

Thanks.
