@elliottower Do you know why the DM-Lab tests are not failing?

@elliottower Do you know why the DM-Lab tests are not failing?

Sorry didn’t see this until now, but am not sure. Took a look and the error seems to be exiting with code 5 but no error message in the action, and pytest has only a warning listed. So it may just be a one off GitHub actions issue, not sure

According to this stack overflow, error 5 occurs when no tests are run which matches the test case https://stackoverflow.com/questions/78061349/why-do-i-get-error-build-process-completed-with-exit-code-5-in-my-python-repo

@elliottower there appears to be an issue importing dm-lab (https://github.com/Farama-Foundation/Shimmy/actions/runs/8186519013/job/22385054336)

That’s super weird maybe we could try different versions of the dm lab package? That’s the only thing that I can imagine changed.
