I followed that installation doc and I can’t install it I always got the errors. I even try to install it via Anaconda and have errors.

maybe you should post the error because like that is is vague … is it a python erreor ? an unity error ? an error during installation ? during training ?

I figured how to setup everything thanks to this links:

I follow this tutorial:
youtube.com/watch?v=Yix4iV_io6o&t=91s

Modified the required versions:
0.30.0 installation fails under Python 3.10 · Issue #5826 · Unity-Technologies/ml-agents · GitHub

Currently, you have to clone the repository, and adjust the following lines:
In ml-agents/setup.py:
python_requires=“>=3.8.13,<3.11.0” (line 82)

In ml-agents-envs/setup.py:
“numpy>=1.14.1,<1.24” (line 54)
and
python_requires=“>=3.8.13,<3.11.0” (line 63)

and delete “numpy==1.21.2” (line 60)

Then, first install torch using your needed configuration (Start Locally | PyTorch) and then install your locally changed python packages:

pip3 install -e ./ml-agents-envs
pip3 install -e ./ml-agents

Used commands from:

and then used command -
pip install protobuf==3.20

And now evrithing is woking.

Thanks! Very helpful.

As of today - for others having similar problems following the Unity docs - this still works, but with the current recommended python the line:

python_requires=“>=3.10.1,<=3.10.12”,

is now in both setup.py files
