Nevermind, all good.
You need to carefully set cudaCapabilities for it to run fine on a given GPU: https://github.com/NixOS/nixpkgs/pull/499323#issuecomment-4049769046 should it have an isBroken if cudaCapabilities has more than one item, then? | 20:42:25 |
 GaƩtan Lepage | Not really. It selects the highest (techically, the last) capability from your config.cudaCapabilities.
So there's no fundamental reason why a list with additional, lower caps than the one of your GPU could not work. | 22:14:15 |

 Bryan Honof | Thanks! That seems to have built succesfully. :) | 09:26:19 |

 connor (burnt/out) (UTC-8) | Does https://docs.nvidia.com/cuda/cuda-toolkit-release-notes/index.html#cuda-compiler (improved C++ standards conformance bullet) mean we could drop our patches to NVCC for 13.2? | 22:38:09 |
|  kirillrdy joined the room. | 22:48:24 |
| kirillrdy | connor (burnt/out) (UTC-8): git blame pkgs/development/cuda-modules/packages/tests/onnx-tensorrt/short.nix shows your name, is there onnx-tensorrt support in nixpkgs ? i think not | 23:03:22 |
| connor (burnt/out) (UTC-8) | No, I packaged a bunch of stuff in https://github.com/connorbaker/cuda-packages but haven't had the chance to upstream it because they have massive dependency chains and I also need to support every release since CUDA 11.4 š« | 23:47:30 |
| kirillrdy | ah awesome ! thanks for the link | 23:48:25 |
| kirillrdy | i guess i could have searched myself | 23:48:42 |

| Kevin Mittman (jetlagged/UTC-7) | kirillrdy: do you happen to know how is it related to libnvonnxparser ? | 03:55:22 |
| connor (burnt/out) (UTC-8) | iirc it provides that lib when built; see https://github.com/onnx/onnx-tensorrt/blob/10.15-GA/NvOnnxParser.h. I think previously when I packaged it (with the intention of upstreaming it to Nixpkgs, never got around to it) I preferred to use libnvonnxparser from onnx-tensorrt instead of the one provided by the tensorrt binary archives | 06:00:28 |
| connor (burnt/out) (UTC-8) | ugh there's still a typo on the TensorRT page where ONNX is spelled "ONYX" https://developer.nvidia.com/tensorrt#:~:text=for%20production%20applications.-,ONYX,-%3A | 06:01:30 |
| connor (burnt/out) (UTC-8) | GaƩtan Lepage: various patches for CUDA 13 stuff https://github.com/ConnorBaker/blender-temp/blob/7132a52cd929b764e83dc97fb0596b8caae58c95/overlay.nix | 06:43:24 |
| GaƩtan Lepage | Thanks for sharing :) | 11:32:30 |
|  ereslibre removed their profile picture. | 15:52:02 |
| ereslibre | hello! was wondering, can we get github.com/NixOS/nixpkgs/pull/489218 merged? Thank you :) | 15:52:49 |
| GaƩtan Lepage | connor (burnt/out) (UTC-8), can you stamp https://github.com/NixOS/nixpkgs/pull/501079 whenever you have a minute please? | 17:55:27 |
| ereslibre | thanks connor (burnt/out) (UTC-8) ! | 17:56:59 |

| @zopieux:matrix.org | Looks like https://hydra.nixos-cuda.org/ is down? | 15:32:25 |
| GaƩtan Lepage | Yes, the web interface has been flaky today. I'll try to restart the box. | 20:26:20 |
| GaƩtan Lepage | Seems up, for now at least | 20:38:02 |
| @zopieux:matrix.org | Thanks! | 20:38:43 |

https://github.com/NixOS/nixpkgs/pull/501901 | 00:48:08 |
| GaƩtan Lepage | I'll probably merge it later today. Testing has been good so far. | 09:23:22 |

Merged!
Feel free to report any regression here :) | 16:12:28 |
