Train stopping with no error message

[istoya]

When executing this command from the recvis20 branch:

python -m nmp.train Maze-Simple-v0 maze_baseline --horizon 75 --seed 0 --epochs 1500

The train stops execution at a seemingly random epoch without showing an error message.
The last thing displayed is:

time/epoch (s)                 32.501863999999486
time/total (s)                 101.7254610999997
Epoch                          2
-----------------------------  --------------------

The train managed to finish once and run all 1500 epochs but all other runs have ended as previously described. I am running my tests on Windows 11 in a conda environment.

Is this an issue you have experienced and might have insight on?
