[Question] AsyncVectorEnv getting hung up as `pip.recv()` not returning anything for `_check_observation_spaces` about gym HOT 3 OPEN

Gym 0.15 is 5 years old, I suspect that no one will be able to help without the project being updated to a more recent version

Are you able to use a sync vector env?

Hey, thanks for the response. I realize the gym version I'm using is outdated and that I might just have to bite the bullet and update the project going forward. But yeah, everything else seems to work fine. I can use SyncVectorEnv, which works as expected. Am trying to use AsyncVectorEnv as I'm expecting this to significantly speed up training.

Async will speed things up but generally not by that much, maybe 10/20% would be my guess
