 SomeoneSerge (back on matrix) | I just keep subscribing to issues but idk when I'll have the energy to reply like... to any of the github pings | 13:56:05 |
 Gaétan Lepage | In reply to @hexa:lossy.network
is anyone looking into the triton-llvm test issues on staging-next? Can we at least mark it as broken, because every attempt at building it is currently useless and wasting CPU time ? | 14:01:16 |

 hexa | is this the royal we? | 14:02:08 |
| Gaétan Lepage | I meant, would you be OK with that ? | 14:02:33 |
| Gaétan Lepage | I can make the PR, but I prefer to ask before | 14:02:45 |
| hexa | I don't maintain that package 😄 | 14:04:34 |
| hexa | ideally someone can disable that test instead? | 14:04:50 |

 matthewcroughan | Amen, you are not being well enough supported financially to solve tough issues, most people in this community are not. | 14:38:25 |
| matthewcroughan | The polish is a matter of resources | 14:38:58 |
| matthewcroughan | I did some postfixups, etc and worked around it | 14:39:15 |
| matthewcroughan | But yes I also landed on the same PRs as you, and I'm not sure why it is still an issue despite those PR's having been merged | 14:39:32 |

| Collin Arnett | Hello, are there any packages in the hackellPackage set that setup cudaSupport that I can use as an example to add cuda support for hasktorch? The author submitted a PR to bump the version here and has marked it as broken so I figured it would be good to get first class cuda support implemented here as well.

| SomeoneSerge (back on matrix) | Oooooh that's a really great question, not least because, afaik, the haskell package set is its own thing with slightly different override patterns than elsewhere? | 00:04:12 |
| SomeoneSerge (back on matrix) | I imagine haskell packages are auto-generated? If so, there must be some customization examples for other native/ffi libraries that might use dlopen at runtime or pkg-config at build time, e.g. wrappers for opengl or vulkan | 00:07:08 |
 connor (he/him) | If accelerate is working or supported, check that out. Not sure it’s still supported given it relies on LLVM 12 (or earlier) for LLVM-HS.
Outside of that, not sure what people use for GPU stuff with Haskell | 00:14:03 |

 Jesse | Does anyone have any configuration files for deep learning on nixos? I want to use cuda to train pytorch models on nixos, but I can't install cuda and cudnn correctly. I tried some but failed. Can anyone share the configuration files with me? I use a 4090 graphics card. | 10:43:05 |
| Gaétan Lepage | Have you set cudaSupport = true in your nixpkgs config ? | 10:43:54 |
| Gaétan Lepage | This enables cuda support for all packages that support it in nixpkgs | 10:44:08 |
|  @trofi:matrix.org joined the room. | 15:50:27 |
| @trofi:matrix.org | Please have a look at https://github.com/NixOS/nixpkgs/pull/368366 . I have no idea what I am doing. | 15:50:46 |
| connor (he/him) | Oh my god builtins.sort requires strict total orderings? | 16:28:17 |
| @trofi:matrix.org | No, it requires strict weak ordering, but >= does not provide it. a >= b can't act as lessThat. b < a can, or !(b >= a) can as well. | 16:31:28 |
| SomeoneSerge (back on matrix) | Read your blog post. You got a talent for discovering this stuff before anyone else | 18:57:22 |
| @trofi:matrix.org | If it makes you feel a bit better cuda is not alone in getting sort a bit wrong:
