You can see that it support several variations for building (CUDA, metal, mkl...)

-> What should be the approach ? Adding cudaSupport ? metalSupport ? mklSupport ?

This looks like it could work !
However, how do you apply a patch to a wheel-type python derivation ?

when using localai 2.15 from unstable and even after a reboot I get ggml_cuda_init: failed to initialize CUDA: CUDA driver is a stub library. It's a bit random but if anyone has a tip, I take it. nvidia-smi output looks fine

Does it allow enabling multiple features at once?

Hey, can I ask for help with compiling alice-vision on NixOS?

In reply to @ss:someonex.net
Looking more closely, I'd guess the issue is somewhere around __has_include(<Imath/half.h>) in ${openimageio.dev}/include/OpenImageIO/half.h

Yeah, I had already figured out it but the bug issue is that I don't know what is the "right" way to include the definition of the half type.

To make matters worse, I've tried to compile AliceVision on a docker container and using the official compilation scripts and yet the thing keeps failing. This means I can't even look at how the thing is supposed to compile.

I'm at a bit of a loss as for how to proceed, but I suspect that I'll have to either ask the original authors for help or carefully read the cmake compilation scripts in order to look for potential sources of the error.

Theoretically AliceVision has a nice CI pipeline but I can't see their build history so I don't even know how useful their CI scripts are.

I dont seem to have any cuda library in /run/opengl-driver/. Should I add anything into hardware.opengl.extraPackages ?

Huh, not sure how that's working for you since I can't get it to build:

$ cat ~/.config/nixpkgs/config.nix 
{
  allowAliases = false;
  allowBroken = false;
  allowUnfree = true;
  checkMeta = true;
  cudaCapabilities = [ "7.5" ];
  cudaSupport = true;
}
$ nix run --impure -L --show-trace --builders '' --max-jobs 1 github:nixos/nixpkgs/c7b821ba2e1e635ba5a76d299af62821cbcb09f3#local-ai
