Issues running MT50 #440

Closed JosselinSomervilleRoberts closed 1 year ago

JosselinSomervilleRoberts commented 1 year ago

Hi,

I really struggle to run MT50. In the beginning, it creates all the environments for the training and evaluation (100 environments so). It always crashes during any training. I have quite a powerful computer and still, this does not work:

Are there any tricks for running MT50? Thanks!

Hey, that is surprising that it is crashing. Can you confirm if it is a RAM issue thorough observing your system manager while running the script? Or identify what particular instruction seems to cause this issue? Is there a minimal script to reproduce the issue that we can run?

@reginald-mclean Any ideas on what the cause might be?

reginald-mclean commented 1 year ago

These are multitask environments so you evaluate on the same environments you train on. So you might not need 2 copies of every env. Can you provide more info about your use case? What algorithms?

Sorry for getting back to you so late. The repo I forked from was indeed creating both test and train environments while it was not necessary. This meant 100 environments which I think was too much for my hardware. Changing this to only 50 environments fixed the issue, thank you for you answer!
