Based on the error message, it seems that there is an issue with the gym package in your Python environment. The error message suggests that there is a problem with an 'EntryPoints' object not having the 'get' attribute. This may be caused by a version incompatibility or a missing dependency.

You can try to resolve this issue by updating the gym package and any dependencies it may have. You can do this by running the following command in your terminal:

pip install --upgrade gym

If this does not work, you can also try to uninstall and then reinstall the gym package:

pip uninstall gym
pip install gym

If neither of these solutions work, you may need to investigate further or seek help from the gym community.
