Hi, thanks for reporting this issue.

I just cloned the repo, navigated to Car Racing, and then installed the environment as instructed on the readme, and ran python collect_data.py

I couldn't see this issue, I suppose it might have something to do with your setup. I am running a MacBook Pro Mac OS Monterey v 12.2.1, Apple M1 Pro

Gym can be a pain to setup, if it helps here is the environment as I see it now.

I solve this question by pip install swig
