@bot-wxt1221:matrix.orgBot_wxt1221Oh but firefox currently is not in the cuda hydra job08:55:59
@glepage:matrix.orgGaétan Lepage Is firefox affected by cudaSupport = true? I have it enabled on my system and never had to recompile firefox... 08:58:34
@bot-wxt1221:matrix.orgBot_wxt1221I believe it isn't before08:59:25
@bot-wxt1221:matrix.orgBot_wxt1221But it did on nixpkgs-unstable now08:59:35
@bot-wxt1221:matrix.orgBot_wxt1221on rev 18dd725c29603f582cf1900e0d25f9f1063dbf1108:59:51
@bot-wxt1221:matrix.orgBot_wxt1221It's because onnxruntime.09:00:02
@bot-wxt1221:matrix.orgBot_wxt1221I override onnxruntime with cudaSupport = false occlSupport = false;09:00:19
@bot-wxt1221:matrix.orgBot_wxt1221Then it could pull from cache.nixos.org09:00:28
@bot-wxt1221:matrix.orgBot_wxt1221But It compile if is without override09:00:39
@glepage:matrix.orgGaétan Lepage

Yes it's not (yet) on nixos-unstable:

nixpkgs on  nixos-unstable took 18s
❮ nom-build --arg config '{ allowUnfree = true; cudaSupport = true;}' -A firefox
Finished at 11:00:15 after 6s
/nix/store/c0g2fha7g7zbd3y74dm0rw1q8ghg89ya-firefox-142.0

nixpkgs on  nixos-unstable took 6s
❯ nom-build --arg config '{ allowUnfree = true; cudaSupport = false;}' -A firefox
Finished at 11:00:24 after 5s
/nix/store/c0g2fha7g7zbd3y74dm0rw1q8ghg89ya-firefox-142.0
09:00:42
@bot-wxt1221:matrix.orgBot_wxt1221But on nixpkgs-unstable09:01:22
@glepage:matrix.orgGaétan Lepage Ok ok. That's not ideal I guess.

In reply to @glepage:matrix.org

I'm having issues with updating torch to 2.8.0
https://github.com/NixOS/nixpkgs/pull/431973

ERROR Missing dependencies:
        setuptools<80.0,>=62.3.0

And I was not able to find any mentions of this constraint in the code base...

yeah this is the exact issue we talked about above, probably patch and provide distutils.
in my flake I just pass an older distutils
13:24:20
@glepage:matrix.orgGaétan Lepage I was able to relax this constraint, without the need for further patching, but now it fails further (during compilation!!) with a Python error stating that it can't find typing_extensions (whereas typing-extensions is in dependencies...) 13:47:41
@connorbaker:matrix.orgconnor (burnt/out) (UTC-8) changed their display name from connor (he/him) (UTC-7) to connor (he/him) (UTC+1).18:33:43
@matthewcroughan:defenestrate.itmatthewcroughan changed their display name from matthewcroughan to matthewcroughan @ nix.camp.18:40:56
@lt1379:matrix.orgLuntorch 2.8 looks ready enough to me now, kicking off a big review run.19:31:40
@glepage:matrix.orgGaétan LepageThanks for the help!19:35:31
@lt1379:matrix.orgLunIf someone has time to check this asteroids-filterbanks fix that'd be nice, it's going to show up as a fail in the torch review https://github.com/NixOS/nixpkgs/pull/43696819:36:45

@connorbaker:matrix.orgconnor (burnt/out) (UTC-8) Alright trying to speed run improvements I made in cuda-packages in https://github.com/NixOS/nixpkgs/pull/437723; Bryan Honof it's still a WIP and saxpy doesn't even run (but it does build!), but it's a start 00:25:44
@connorbaker:matrix.orgconnor (burnt/out) (UTC-8) I couldn't run saxpy built off master either; I'm hoping something was weird with my driver so I'm updating and reboot my desktop with a GPU 12:32:34
@connorbaker:matrix.orgconnor (burnt/out) (UTC-8)Oh thank god it works now12:37:12
@connorbaker:matrix.orgconnor (burnt/out) (UTC-8)If I can't debug things without using GDB I'm just not going to support it12:37:37
@sbc64:matrix.orgsbc64 changed their profile picture.14:23:34
