connor (burnt/out) (UTC-8)	Gaétan Lepageif you haven’t already, can you link any of the additional work you’ve had to do for the OpenCV version bump in the PR description? I remember yesterday you had mentioned needing to fix protobuf, but that might have been about ONNX Runtime.	17:20:11
Gaétan Lepage	Indeed, this was for `protobuf`. The opencv effort is all contained in https://github.com/NixOS/nixpkgs/pull/479136	21:33:06
Gaétan Lepage	The `protobuf` patching related to `onnxruntime` was merged into `staging`. -> https://github.com/NixOS/nixpkgs/pull/480716	21:33:34

Gaétan Lepage	Sadness. I had to package the 12.8 version of cuda-bindings, because we're on cuda 12.8. However, it dlopens `libcuda.so` and the driver (on my system at least) tells it that it uses cuda 13.1. Hence, it errors out :/ https://github.com/NixOS/nixpkgs/pull/482638 (`cuda-bindings` is supposed to be required in the new torch update, not sure how critical it is though)	12:06:42
