Errors in playback for sample demonstrations

[AstroTheKat]

I'm on an M1 MacBook with robosuite installed from source (on the master branch).

I've run into errors with playback for all of the sample demonstrations in robosuite/models/assets/demonstrations, when running python playback_demonstrations_from_hdf5.py from the robosuite/scripts folder.

The command python playback_demonstrations_from_hdf5.py --folder ../models/assets/demonstrations/lift/ gives me the error:

Output

The command python playback_demonstrations_from_hdf5.py --folder ../models/assets/demonstrations/wipe/panda gives me the error (possibly related to #303):

Any idea what might be happening here? Thank you!

Might be that the demos are outdated potentially? If you install with pip, does it give you the same issue?

[AstroTheKat]

Thanks for the suggestion! I switched to the pip installation. The lift demo works now, but I get what looks like the same errors for handover and wipe.

For python playback_demonstrations_from_hdf5.py --folder ../models/assets/demonstrations/handover/panda_panda, I get:
