current requirements.txt uninstallable on fedora 40

I was trying to install this on fedora 40 using the venv method and the conda method - seems that pip decides to install a version of stable-baselines3 that pulls in gym in version 0.21 that is not installable with recent pythons (cf. openai/gym#3176)

I have fixed this locally by forcing stable-baselines3 to version 2.2.1 (no clue if this is a good version) but maybe that is something you might need to look at

Hi, are you installing from the environment.yml?
I think the specified version there is gym==0.26.2 and stable-baselines3==2.2.1 which does not have that problem.

Indeed the README.md doesn't say that one should install from the yml file. Thanks for noticing the issue, I will fix that.
