Hi, @midnightzz1,

I noticed that Rotation and Transform are available under the module gd.utils.transform. To solve the issue, I replaced the line of code from from vgn.utils.transform import Rotation, Transform to from gd.utils.transform import Rotation, Transform.

You can see the modified code in my forked repository at the following link: https://github.com/tc-huang/GraspNeRF/blob/e3e4ce62481eafccbf13112a7350fc1a7b418031/src/gd/utils/btsim.py#L9. I hope this helps you.

Best regards,
tc-huang
