Thanks for sharing the code for your excellent work!

I clone the repo and run python torchbeast/monobeast.py --env=breakout --agent=GCN --xpid=T-1-1. However, it throws an error message "ImportError: Cannot load backend 'TkAgg' which requires the 'tk' interactive framework, as 'headless' is currently running".

I am wondering if MinAtar experiments can run on headless servers. Can you help me? Many thanks!

I am running into the same issue when running in a docker environment. I tried the solution from this SO post but it looks like the code already implements the fix. Any help would be appreciated

Hi, could you check whether this works now?

After pulling in your changes, I am still seeing the same issue with TkAgg
