[BUG] FileNotFoundError: [Errno 2] No such file or directory: '/tmp/nlew7mo9hzl'

[skezle]

🐛 Bug

We get a file not found error when looking for the NetHack temporary directory after running our RL algorithm for > 1M steps. This error doesn't occur on all runs, only some runs get this error. We use the following environment wrapper over MiniHack:
https://github.com/AGI-Labs/continual_rl/blob/develop/continual_rl/experiments/tasks/make_minihack_task.py.

To Reproduce

Steps to reproduce the behavior:

We run our RL algorithm on any Minihack environments (RoomRandom-15x15 or RoomTrap-15x15). Occasionally after around 1M steps we obtain the following FileNotFoundError when looking for the NetHack tmp directory:

Expected behavior

No FileNotFoundError when running our RL algorithm on MiniHack.

Environment

I'm running this on a SLURM scheduler so didn't collect the GPU info.

Additional context

[JupiLogy]

This looks like an NLE problem as the directory creation goes back to there. That, and/or a problem with your computer deleting temp files automatically after a certain amount of time?

Was there any solution to this?
