When running the code in the quickstart, an error occurs:

I tested it locally, and the same issue occurs.

Hi @aiguoli
That is a currently known bug, you should install rl4co with Python < 3.11. You may follow the installation instructions here for now.
We will have a major release in which the problem above should be solved, so stay tuned!
