What version of pytorch do you have? If you install our prebuilt wheels (for intel mac) they will only work with PyTorch 1.13.0. It may help to build from source?

Can you share your pip list and conda list. When you say "reinstall", did you try starting again in a new environment? I recommend that.

Why are you trying pytorch3d 0.6.1? Main thing is: Does it work in a new environment with torch 1.13.0 and latest pytorch3d?
