This PR should fix the last failing gpuCheck instance, i.e. python3Packages.triton.gpuCheck: https://github.com/NixOS/nixpkgs/pull/488887
I discovered one of our beloved dlopen instance in triton. We didn't know about it since then... This PR fixes it too. | 23:39:42 |

 connor (he/him) | Don't think I linked it here, maybe interesting for people with heavy eval jobs: https://github.com/ConnorBaker/nix-optimization | 01:41:36 |

| connor (he/him) | Gaétan Lepage: there's a merge conflict and I need to rebase, but IIRC something like https://github.com/NixOS/nixpkgs/pull/485208 is necessary to make CUDA 13 the default.
I still need to do the same for the PyCuda PR I have: https://github.com/NixOS/nixpkgs/pull/465047. Apologies that's taking me so long. | 18:56:11 |

| Gaétan Lepage | Ok thanks! I should get a notification when you'll have rebased. | 07:52:34 |

Do we want to drop it as an input to torch soon? Gaétan Lepage | 23:01:56 |

| Gaétan Lepage | Well, we will follow what upstream says. Is this warning shipped as part of 2.10.0? | 21:45:18 |

| Lun | too late for 2.10 | 00:02:10 |
| Gaétan Lepage | Ok, I guess we'll just wait for the next release then? | 20:09:10 |

 Kevin Mittman (jetlagged/UTC+8) | Is there an hardcap on input tarball size? Considering splitting a particularly large one into multiple components | 01:54:03 |
| connor (he/him) | Not that I’m aware of. But such a change would require some rework on the Nixpkgs side to recombine sources or know which components to pick (which isn’t necessarily bad, just a thing that would need to happen). | 17:20:26 |

 Bot_wxt1221 | Why nvidia-open beta is still broken? | 01:30:50 |
| Bot_wxt1221 | None cares it? | 01:30:58 |
| Kevin Mittman (jetlagged/UTC+8) | Broken in what way? Which version is it 590.48.01 ? | 03:13:32 |
| connor (he/him) | The drivers are maintained by a different team -- we are the NixOS CUDA team | 04:19:31 |
 hexa | is partially opting into cuda support even a supported thing? https://github.com/NixOS/nixpkgs/pull/489829/changes#r2841902335 | 15:40:55 |
| connor (he/him) | It is not | 16:51:10 |
| connor (he/him) | That’s partly why it’s a global config option
Otherwise people get inconsistent closures and failure modes that make me want to yell at people :( | 16:51:31 |
| hexa | Thanks! | 16:52:11 |

Changelog: https://github.com/pytorch/pytorch/releases/tag/v2.10.0
PR: https://github.com/NixOS/nixpkgs/pull/484881
PR tracker: https://nixpkgs-tracker.ocfox.me/?pr=484881
This one took quite a while to bring to nixpkgs, and I'm glad to have finally gotten it merged!
Some basic testing has been done (basic builds, cudaSupport builds, some gpuChecks).
However, exhaustively building and testing all the downstream dependencies isn't feasible (at least without more time and hardware).
-> Please, don't hesitate to report any breakage in this channel, and feel free to ping me as well.
Thanks a lot to everyone who helped, and more generally to everyone else for your patience. | 23:30:01 |
