Get error from ninja. about pytorch3d HOT 5 OPEN

I suspect you don't have enough visual studio components installed to build C++ python extensions. Also it's worth checking through the other issues which include "The system cannot find the file specified" like yours. We've had a few.

Thanks for the reply. What I am installing is community version of VS2022

I think you need to be running in that "x64 Native Tools Command Prompt..." not in a normal command prompt.

What happens when you type "nvcc" at the prompt?

And can you go back to the VS installer and install lots of components? I can't remember exactly which ones you need, but this error can be a symptom of not having enough. Maybe look at other issues...

Thanks for your reply, What I am choosing is "x64 Native Tools Command Prompt..." , becasue it run [vcvarsall.bat] to setup env.
I run this [vcvarsall.bat] in my conda env to simulate that.

I will check the VS installation later. Is there any other workround for that, like wheels file?

No - on Windows you need to build from source with Visual Studio.
