Hey. First of all, great tutorial.

I was hoping you could help with a error i've been seeing a lot in the comments. I was getting this error :""ERROR: Could not build wheels for numpy, which is required to install pyproject.toml-based projects"", so i tried to use your "requirements.txt" file and install the packages with the "correct" versions you specified. I couldn't help but notice the same error when typing "pip install - r requirements.txt" in cmd. I am using python 3.10.0, I also updated pip to the latest version, but i keep getting this error :
RuntimeError: Broken toolchain: cannot link a simple C program
[end of output]

note: This error originates from a subprocess, and is likely not a problem with pip.
ERROR: Failed building wheel for numpy
Failed to build numpy
ERROR: ERROR: Failed to build installable wheels for some pyproject.toml based projects (numpy)"

Could it be some C++ tools i didnt install (yes i did download the vs build tools for C++, v:14.0)

Also i was wondering if i can follow an outdated tutorial (say CodeMonkey's tutorial for example) and use older versions of torch, python, mlagents etc... Would it theoreticaly work ?

I am soo glad somebody is making a update to his older setup!

This is the best tutorial on installing ML Agents atm. I followed some other tutorials and documentation but got frustrated after trying so many different versions and nothing worked. This video will get everything working, so thanks a lot!

[valongaming]

Thank you very much. I saw Code Monkey's videos and thought it's gonna be perfect, but the installation was weird, so I started looking and your vid is perfect for filling that gap.

Edit: my comments do show up unless you sort by newest first idk why

i always get this error message when installing mlagents in python :
"ERROR: Could not build wheels for numpy, which is required to install pyproject.toml-based projects"
I already tried installing numpy by itself but it was already there
could someone please help me?

[nicholaspaleologos]

I was hoping you could help as I get the error: TypeError: Invalid first argument to `register()`. typing.Dict[mlagents.trainers.settings.RewardSignalType, is not a class or union type.

I am using 3.11.9 but i have tried python 3.10 and get the same error and help would be greatly appreciated
