Error messages upon env deletion #97

Closed StoneT2000 closed 1 year ago

StoneT2000 commented 1 year ago

When creating an environment then rendering (rgb or human viewer) I seem to always get a verbose error output at the end as so

Created environment with name Lift

Any idea what causes this? Doesn't break anything but it would be nice to be able to not have this popup each time.

Duplicate of https://github.com/ARISE-Initiative/robomimic/issues/56 - unfortunately this seems to be coming from MuJoCo itself. While annoying, it does not affect any functionality in the code, and can be safely ignored.
