@Trinkle23897 PettingZoo*Tianshou tutorials are now live at https://pettingzoo.farama.org/tutorials/tianshou/beginner/

They pass CI, so there shouldn't be issues - if there are, feel free to check the workflow at: https://github.com/Farama-Foundation/PettingZoo/blob/master/.github/workflows/linux-tutorials-test.yml

Or just pop me a ping :)

Hope this clears up any confusion!

When I run python test/pettingzoo/test_tic_tac_toe.py:

Also, can you add three links to tianshou's doc? Either create a subsection after multi-agent in cheatsheet, or just insert in that subsection

• https://pettingzoo.farama.org/tutorials/tianshou/intermediate/
• https://pettingzoo.farama.org/tutorials/tianshou/advanced/

I think pettingzoo should maybe directly link/copy this very useful tianshou tutorial https://tianshou.readthedocs.io/en/master/tutorials/tictactoe.html#tic-tac-toe-environment.

@Trinkle23897 Really sorry for the delay. I've just released 1.22.2 for PZ which deals with the WARN bug.
