 Ari Lotter | is this a horrible idea, if i need cuda support and don't want to wait hours for builds? :)

python312Packages = prev.python312Packages.override {
overrides = pyfinal: pyprev: {
torch = pyfinal.torch-bin;

 Gaétan Lepage | RE {cudaPackages.nccl, onnxruntime}: remove reference to nvcc in binary:
We need to patch both nccl's libnccl.so and onnxruntime's libonnxruntime_providers_cuda.so for the fix to actually work. | 23:10:06 |

 connor (he/him) | should be fine, but I'd always recommend using pythonPackagesExtensions since it's a little nicer to use | 06:38:57 |
 SomeoneSerge (matrix works sometimes) | I still have no explanation for why we cannot seem to reproduce the nvcc reference with saxpy | 15:07:47 |
| SomeoneSerge (matrix works sometimes) | It's frustrating | 15:08:03 |
| SomeoneSerge (matrix works sometimes) | Elaborated on github, but here for redundancy: the reference in onnxruntime only appears when nvcc is propagated by all these cuda libs, https://github.com/NixOS/nixpkgs/pull/457424#issuecomment-3475736738 | 15:11:32 |
| Gaétan Lepage | TIL: python3Packages.torchWithRocm is apprently sensitive to config.cudaSupport. | 20:11:25 |
| Ari Lotter | ugh i wish we could compile packages with cudaCapabilities individually per-capability and merge them later, it's such a nightmare adding one new capability level and it causing a huge 8-hour recompile.. | 20:40:40 |
| connor (he/him) | These aliases must die, they make my life so difficult | 21:45:22 |
| connor (he/him) | Join the club
And it’s not even like we could do a mega-build in an intermediate derivation and then prune unused capabilities according to whatever the user requested because the amount of generated device code is so large linking will fail lmao | 21:46:17 |
| connor (he/him) | Gaétan Lepage are any of SomeoneSerge (back on matrix)’s comments on https://github.com/NixOS/nixpkgs/pull/457803 actionable or is it good to merge? | 21:48:00 |
| connor (he/him) | Also, would you mind reviewing https://github.com/NixOS/nixpkgs/pull/458619? | 21:48:09 |
