I am not sure why this error would happen.

Hi! Could you try downgrading to gym==0.21 ? I think gym broke a few things (again). I'll get to fixing for the latest version soon, but for now please try pip install gym==0.21.0

I'm also encountering this issue. Any idea on an ETA for a fix?

semitable commented 2 years ago

@aowen87 Have you tried the solution above (downgrading to 0.21)?

Downgrading works, but I have some package dependencies that want a more recent version. It's not a big deal to remove the other packages for now. I'm just curious if there's an ETA for a longer term fix.

Gym seems to be aggressively changing their API recently and fixes seem to be short-lasting. I believe they will release a v1.0 soon which will stabilise their API. I will happily do a pass when they do, and fix any issues.

Sounds good. Thanks!
