About ray version 1.8.0 for MARLlib

I want to install MARLlib on my PC. But it has dependency with ray == 1.8.0. Pip is telling me that this version is not available. Is there any way I can install ray 1.8.0? Thanks in advance.

Hi @Nafisa_Naznin,

Here are the versions that are available for ray 1.8. My guess is that you are trying to install it with python version > 3.9?

Hello @mannyv, yes the version is 3.10.12

Then you will need to make an environment with python <= 3.9 to pip install ray 1.8

Thank you very much.
