Having issue installing ml-agents

[wangdog123]

I followed the installation doc to try installing ml-agents release 21 with Anaconda.

But when I use python 3.10.x that the doc recommended, both installing pytorch and ml-agents python package gave a error called
ImportError: Module use of python311.dll conflicts with this version of Python.
I also tried install pytorch 1.13.x but gave the same error.

and when I use python 3.11.x, pytorch installed successfully, but when I try to install ml-agents, it installed some modules, but some modules gave the python version mismatch error

How can I install ml-agents on anaconda successfully?

As suggested in the solution in the answer to that link, when creating an anaconda virtual environment, create the Python version as 3.9.18 and then set the recommended minimum Python version in each setup.py to python_requires=">=3.9.1,<=3.10.12" Adjust it to
And if you enter the commands below sequentially, it will be installed properly. I solved the installation error of Release 21 in this way.

pip3 install torch -f https://download.pytorch.org/whl/torch_stable.html
pip3 install -e ./ml-agents-envs
pip3 install -e ./ml-agents
