any body can help me?

I think they are the same problem and might be a bug, however, does doing flatten make it a discrete space? so what is the point of using Multidiscrete?

Another problem I think is that in Multidiscrete action masking, conditional masking is impossible. For example, when the action space is like this: `self.action_space = MultiDiscrete([3,2])` and masking the second...

To bumping it up again, I believe there is still a problem with multiprocessing/connection.py: My Code is: ``` class Custom(gym.Env): def __init__(self, *args, **kwargs): \\\\\\ self.reset() def _STEP(self, action): \\\\\...
