Hello, i'm having trouble during execution of src/example.py (using Python 3.6.15 and Mac OS ventura 13.3.1

Traceback (most recent call last):

Anyone could help ? I run the example with the created venv after runned install.sh

I saw this error recently from someone else and it was due to an updated method in the gym library. I need to push the commit from our internal repo to this github page, but here is the patch in the meantime (this also should allow using more modern python versions and tensorflow 2) 62bfad53fc980ce8b7c7761dec13ac78cb0883fa.patch

Hello, while waiting for the upgrade, I can confirm that works properly with gym 0.18.0. ( I was able to run example.py )

should be fixed now
