Unity Engine

(This is my first post on the forums)

I am working in the unity ver. 2022.3.16f and am working on mlagents. I followed the entire code monkey tutorial and installed python3.7.9, ml agents 0.29 and I installed pytorch ver.1.7.1. then I ran mlagents-learn --help and the following message came at the last:

Torch Configuration:
–torch-device DEVICE
Settings for the default torch.device used in
training, for example, “cpu”, “cuda”, or “cuda:0”
(default: None)

And then I ran: mlagents-learn --run-id=test7

The following errors came:

I don’t know what this means.

Without knowing what is in your front-end, it’s hard to say, but I would personally recommend upgrading all your version:

  • python => upgrade to python 3.10, eg 3.10.16 is the latest
    • personally I use pyenv to install python, it’s super convenient I find
  • ml-agents => git clone the ml-agents github repo, do git checkout release_20, and install from that
  • then see if the problem still persists. Maybe it was fixed in the later version. But if it wasn’t, at least you’ll be on the latest version, and more people will have the same version as you, and can look up the exact filepath and line numbers you are providing

Thanks for your reply! It worked. I just had an old python version!

for me it just gives an error saying numpy failed to build or something
