Error processing AMASS

Hello, I have a problem when I run python data/scripts/convert_amass_to_isaac.py 'path/to/AMASS' --humanoid-type=smplx.
All errors have the prompts like this:
Error: cannot reshape array of size 115395 into shape (785,52,3)
In fact, I found that the second dimension should be 49, not 52 as in the code. I want to know where the problem lies. Should I use the SMPLH (52 joints, 6890 vertices) or SMPLX (55 joints, 10475 vertices) form of the official AMASS dataset?

I have tested it and found that I should download the SMPLX version. I mistakenly used the SMPLH version on certain datasets.

Yes, you're correct.
For the SMPL body we use the SMPL-H files and for SMPL-X we need the full SMPL-X ones.
I'll try to clarify this in the readme.

Thanks!
