Issue with register.py file and Inquiry Regarding Code Adjustment about diffpose

[CYXYZ]

I've found that when I use parameterizations = ["quaternion"], other errors occur, as follows:

(diffpose_copy) (base) cyx@server1:~/autodl-tmp/DiffPose_copy/experiments/deepfluoro$ python register.py

Hi @CYXYZ sorry for the slow response on this. I am working on a big update to DiffDRR (you can track it here), and am waiting to update DiffPose until this is completed. Thank you for your patience.
