Building libtorch for android fails

[bmanga]

🐛 Describe the bug

Building android fails:

I get errors regarding

Cannot find source file:

    ~/Android/Sdk/ndk/25.1.8937393/sources/third_party/vulkan/src/common/vulkan_wrapper.h

Apparently vulkan_wrapper.[h/cpp] haven't been part of ndk for a few versions...

Versions

pytorch main branch

This will probably be something that won't get fixed unfortunately.

PyTorch mobile is being spun down in favor of ExecuTorch so it's expected to move workloads to that instead.

Hello there :)

I am referring to an android build of libtorch, I'm not interested in the pytorch mobile runtime.

As a matter of fact, I was interested in a full libtorch cpu build (including training infrastructure, optimizers etc).
I got it working by hacking some cmake files, but let's say the pytorch cmake code could do with some love 😅
