Dear all, I got the following error telling me about 'extras_require', which I don't understand what went wrong exactly. The building process was successful last week and nothing has been changed since then. Thanks a lot for any advice!

Hi, one of your dependencies isn't compatible with the latest version of setuptools (we are installing the latest version by default now). You can fix your build by explicitly installing a compatible version of setuptools, from openai/gym#3176 (comment), looks like that version is 65.5.0.

You can do this by changing your config file https://github.com/Dong237/RL4LMs/blob/f907aee6610963c05ec450c3e3b892f1277ac66f/.readthedocs.yaml#L15-L19 to:

python:
  install:
    - requirements: setuptools.txt
    - method: pip
      path: .
    - requirements: requirements.txt

Wher setuptools.txt has setuptools==65.5.0

Problem now solved, thank you so much!!

Hi I just added setuptools.txt to the root directory containing setuptools==65.5.0, and also add it to .readthedocs.yaml file as suggested above. Then it worked.
