🤣 I can't read this, but I can guess what it says... 🤣

The latest commit bd52f4a on main has broken the ability to build pytorch3d with PyTorch older than 2.1 , because it relies on c10::optional being the same as std::optional. I imagine in the near future that change will either be reverted, or we will explicitly insist on newer pytorch. Meanwhile you can revert the change locally e.g. by git checkout 17117106e : the previous commit is 1711710 .

This got fixed.
