 Daniel Fahey | For the package maintainer(s) to look into it | 18:41:02 |
 Ari Lotter | yeah workin on it š | 18:41:34 |
| Ari Lotter | it's ~100k lines of code i gotta narrow down heh | 18:41:46 |
 connor (burnt/out) (UTC-8) | SomeoneSerge (back on matrix)GaĆ©tan LepageI added you both as collaborators on my fork of Nixpkgs. I had a death in the family so Iām going to be in and out. We need to get this PR fixed up and merged: https://github.com/NixOS/nixpkgs/pull/456510
We also need to get this PR merged: https://github.com/NixOS/nixpkgs/pull/459416
I likely wonāt have time to do that over the next few days. Can you two do that for me? | 19:12:06 |
 leona | take care <3 | 20:40:59 |
| Daniel Fahey | Condolences | 21:24:01 |
| Ari Lotter | yeah, givin up - jax dies every time :( | 21:34:25 |
| Daniel Fahey | haha, well done for trying | 22:19:37 |
 GaƩtan Lepage | I'm so sorry Connor. Take your time. Focus on what matters the most for you right now (i.e. not CUDA).
I'll look at those two PRs. Please message me if I can do anything else. | 23:04:38 |
| Ari Lotter | yeaaah, this is somethin' real broken with the torch 2.9.0 update :/
gonna see if i can figure it out, but it just doesn't seem that nvrtc is in the run path. looking fora way to repro it without my whole binary š | 23:17:18 |
| GaƩtan Lepage | Redacted or Malformed Event | 23:29:07 |
| GaƩtan Lepage | torch 2.9.1 is out. And triton 3.5.1. And both staging-next and staging-nixos were merged into master a few hours ago.
CPUs will have to work hard for the next few days... | 23:29:21 |

 SomeoneSerge (back on matrix) | They come not single spies... really sorry to hear this, Connor. Take care | 14:07:48 |
| Ari Lotter | oh woof, but torch-bin is 2.9.1 and torch is still 2.9.0 | 15:10:16 |
| Ari Lotter | aha, repro'd :D | 16:15:41 |
| Ari Lotter | https://github.com/NixOS/nixpkgs/issues/461334
issue opened :) | 18:54:11 |

 hexa (UTC+1) | https://hydra.nixos-cuda.org/build/14219 magma runs into the output limit | 04:50:01 |
| hexa (UTC+1) | and https://hydra.nixos-cuda.org/jobset/nixos-cuda/cuda-packages-v2#tabs-jobs has no torch package š¤ | 04:50:51 |
| GaƩtan Lepage | I increased it from 4GB (what nix-community has I think) to 8GB. And it seems to still be broken... | 08:53:41 |
| GaƩtan Lepage | This is very weird. It ends up being built anyway as a dependency. I'll try to investigate... | 08:55:38 |
| GaƩtan Lepage | Ok, I figured it out. torch and torchWithoutRocm have the same outPaths. So torch is getting filtered out in favor of torchWithoutRocm. | 09:25:13 |
| Ari Lotter | realized this isn't a 2.9 regression, it's a -bin vs source problem :/ | 18:37:14 |
| Ari Lotter | bin works fine T_T | 18:37:19 |
| Ari Lotter | updated the ticket :) | 18:37:29 |
| GaƩtan Lepage | I updated torch-bin to 2.9.1 yesterday. The PR for the source-based build is https://github.com/NixOS/nixpkgs/pull/461241 | 21:55:22 |
 apyh | i see your commit message says torch 2.8->2.9, but it's actually 2.9->2.9.1 :) | 21:56:32 |
| GaƩtan Lepage | Good catch, now fixed. | 22:06:15 |

|  cafkafk joined the room. | 12:47:57 |
| GaƩtan Lepage | SomeoneSerge (back on matrix) would you have a minute to take a look at the triton/torch bump?
https://github.com/NixOS/nixpkgs/pull/461241 | 14:23:53 |
| GaƩtan Lepage | Built with and without CUDA. No obvious regressions. | 14:24:19 |
