I have tried change python 3.9 to python 3.11, and pip install --user --upgrade setuptools . It still doesn't work.

Hi @xiangxiang0826, I assume this is the result of

pip install diambra
pip install diambra-arena

Right? If yes, this seems to be related with a recent change with pip. We will move from setup.py to pyproject.toml soon, but for now the workaround that should work is installing a specific wheel version before installing diambra:

pip install wheel==0.38.4
pip install diambra
pip install diambra-arena

Can you try that and let us know if this solved the problem?

Please note that you should use max python 3.10, not 3.11.

@xiangxiang0826 we just found out that another python package has conflicts with the current dependency structure, so instead of pinning wheel you need, for now, to pn setuptools, so this is the workaround to install diambra:

1) Create a containerized environment using (mini)conda and a given python version (e.g. 3.9): conda create -n diambra python=3.9 2) Install diambra-arena as follows:

pip install setuptools==66.0.0
pip install diambra
pip install diambra-arena

This should fix your problem.

We will be releasing an updated version soon that should integrate this fix, and I will keep this issue open until then.

@xiangxiang0826 this is just to confirm that we fixed this issue and just released a new diambra-arena version 2.1.0rc12 (https://pypi.org/project/diambra-arena/), so you should now be able to properly install the package with the standard commands:

pip install diambra
pip install diambra-arena

This closes this issue, but do not hesitate to write again in case you need additional support
