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

https://github.com/NixOS/nixpkgs/pull/498612 Would it be helpful to have a repackaging guide for the GPU driver? | 04:38:48 |
| Gaétan Lepage | FYI: The default cudaPackages version was updated from 12.8 to 12.9
I tested core packages, but I would not be surprised if regressions were to show up. Feel free to report them here.

Would it be helpful to have a repackaging guide for the GPU driver? Could you clarify what you mean by 'repackaging' and what specific scenarios the guide would cover? | 16:54:40 |
| Kevin Mittman (jetlagged/UTC-7) | Well for example there is a reference to bumblebee but https://docs.nvidia.com/datacenter/tesla/driver-installation-guide/latest/optimus-laptops-and-multi-gpu-desktop-systems.html | 17:31:50 |

 connor (he/him) | Gaétan Lepage: would you have the bandwidth to review https://github.com/NixOS/nixpkgs/pull/497675? | 00:26:38 |
| Gaétan Lepage | For sure! The diff is fairly trivial. The bulk of the job will be the testing.
yorik.sar this is a good candidate for testing the new GitHub app on our infra. | 00:34:39 |
| Gaétan Lepage | FYI: The PR updating jax to 0.9.2 and the rest of the ecosystem with it (22 commits 🫠) has finally been merged! (after 2 months of efforts)

| Gaétan Lepage | Do we agree that pytorch got their upper bounds wrong?
https://github.com/pytorch/pytorch/blob/v2.11.0/torch/utils/cpp_extension.py#L75
https://docs.nvidia.com/cuda/archive/12.9.1/cuda-installation-guide-linux/index.html#host-compiler-support-policy
GCC 14.x should be supported with cuda 12.9 | 14:46:42 |
| Gaétan Lepage | Also, it's unclear why this only blows up in torchvision and not in torch itself... | 14:48:33 |
| Gaétan Lepage | Looking for reviewers on:
| 21:39:29 |
| Gaétan Lepage | 🔥 PyTorch 2.11.0 (+ torchcodec 0.11.0) 🔥
Changelog: https://github.com/pytorch/pytorch/releases/tag/v2.11.0
PR: https://github.com/NixOS/nixpkgs/pull/502810
PR tracker: https://nixpkgs-tracker.ocfox.me/?pr=502810
Notable changes on the nix packaging side:
rocmSupport for torchcodecrocmSupport for torchaudio- revamp of the
torchaudio derivation, addition of testing
- Addition of
torchaudio.gpuCheck
This one only took me 4 days 🚀 I hope it doesn't break too many things 🥸 | 23:34:55 |

| Gaétan Lepage | Update, indeed, they messed it up: https://github.com/pytorch/pytorch/commit/39565a7dcf8f93ea22cedeaa20088b24ff6d2634 | 10:29:17 |

 tpw_rules | hey. i had previously sympathzied with samuela and like i said before had some of the same frustrations. i just edited my github comment to add "[CUDA] packages are universally complicated, fragile to package, and critical to daily operations. Nix being able to manage them is unbelievably helpful to those of us who work with them regularly, even if support is downgraded to only having an expectation of function on stable branches." | 03:29:14 |
| Winter (she/her) | In reply to @tpw_rules:matrix.org
i'm mildly peeved about a recent merging of something i maintain where i'm pretty sure the merger does not own the expensive hardware required to properly test the package. i don't think it broke anything but i was given precisely 45 minutes to see the notification before somebody merged it ugh, 45 minutes? that's... not great. not to air dirty laundry but did you do what samuela did in the wandb PR and at least say that that wasn't a great thing to do? (not sure how else to word that, you get what i mean) | 03:30:23 |
| tpw_rules | no, i haven't yet, but i probably will | 03:31:03 |
| Winter (she/her) | i admittedly did that with a PR once, i forget how long the maintainer was requested for but i merged it because multiple people reported it fixed the issue. the maintainer said "hey, don't do that" after and now i do think twice before merging. so it could help, is what i'm saying. | 03:31:50 |
| tpw_rules | i'm not sure what went wrong with the wandb PR anyway, i think it was just a boneheaded move on the maintainer's part | 03:32:10 |
| Winter (she/her) | (it was also simple enough that it was fine and the maintainer said it looked good after) | 03:32:15 |
| tpw_rules | * i'm not sure what went wrong with the wandb PR anyway, i think it was just a boneheaded move on the merger's part | 03:32:19 |
| tpw_rules | but i thought most of the frustration was around packages which don't really involve CUDA breaking the fragile CUDA packages, and i'm not sure how the warning helps in this case. it's not like nixpkgs-review prints out the comments. maybe i'm wrong. but it is a legitimate problem | 03:34:19 |
