Describe the bug

I can solve the one problem in this issue list.

# Go inside the repository and install the package
%cd ml-agents
!pip3 install -e ./ml-agents-envs
!pip3 install -e ./ml-agents

This part is so annoying, but I solved. Just type "%%capture" top of that codes.

But I have one more problem.

!mlagents-learn ./config/ppo/SnowballTarget.yaml --env=./training-envs-executables/linux/SnowballTarget/SnowballTarget --run-id="SnowballTarget1" --no-graphics

This part's output is /bin/bash: line 1: mlagents-learn: command not found.
I can't solve this bug. I tried !pip install mlagents, etc. But all failed.
please help me.

based on my research I think the current ML agent do not support the python version beyond 3.10
and i have add the following code in the beginning to down grade python version to 3.10
here is how I updated the version
!python --version
!sudo apt-get install python3.10
!sudo update-alternatives --config python3
!python --version
!sudo apt install python3-pip

it will ask you to select the version to use and you have to select the one with 3.10
