SMACv2 baseline QMIX in smacv2/RUNNING_EXPERIMENTS.md error

I'm trying to run SMACv2 baseline QMIX in smacv2/RUNNING_EXPERIMENTS.md. However, I keep running into this error:

Hello from the pygame community. https://www.pygame.org/contribute.html

I've tried a few things but I'm not sure how to solve this. Is this a conda error or a git error? Any help on solving this would be much appreciated! Thank you.

Hi! Thanks for raising an issue 😄. I will get to this when I am back from travelling next week. To help me can you tell me a simple way to reproduce the error -- i.e.:

1. What command you were exactly running?
2. What you had done before that?

To my mind this looks like a git error but I'm not sure.

For now, I ran the QMIX algorithm without the docker and it ran fine. I guess you can close this issue for now.
