I am trying to install pytorch3d running

MACOSX_DEPLOYMENT_TARGET=10.14 CC=clang CXX=clang++ pip install "git+https://github.com/facebookresearch/pytorch3d.git"

or

MACOSX_DEPLOYMENT_TARGET=11.0 CC=clang CXX=clang++ pip install "git+https://github.com/facebookresearch/pytorch3d.git"

and installation fails.

In logs I can find lots of errors like this:

For some reason I am having problems with make_float3. Any ideas?

I suspect the recent commit https://github.com/facebookresearch/pytorch3d/commit/6b8766080d2c331a05abbddbf3c7332dbb9df791 broke it. Can you try reverting that locally?

We need to work out what the proper fix is for non-cuda builds.

Yes, thanks. I was able to install it from commit c373a84.

Happy to test any new release in mac. Just ping me.

I had the same problem. Install worked following ivanlen but I also had to find the ninja build file, run ninja manually, and then it was ok.

This should be fixed on main now, by https://github.com/facebookresearch/pytorch3d/commit/3621a36494db27336a89503dded7ca896bb059d7 .
