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 (he/him) changed their display name from connor (he/him) (UTC-7) to connor (he/him) (UTC+1).18:33:43
@matthewcroughan:defenestrate.itmatthewcroughan @ 39c3 (DECT 94667 or 97340 or 67192) 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 (he/him) 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 (he/him) 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 (he/him)Oh thank god it works now12:37:12
@connorbaker:matrix.orgconnor (he/him)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
@lt1379:matrix.orgLuntorch._inductor.exc.InductorError: FileNotFoundError: [Errno 2] No such file or directory: 'openssl' python312Packages.depyf is failing on the 2.8 bump PR in inductor errors looking for openssl. only 3.12, 3.13 depyf is fine. before the bump both 3.12 and 3.13 worked. 😕16:34:32
@apache8080:matrix.orgapache8080 I have machine where I enable the nvidia drivers and cudatoolkit but I don't see /dev/nvidia-uvm and when I lsmod I don't see the kernel module either 20:20:54
@apache8080:matrix.orgapache8080 * I have a machine where I enable the nvidia drivers and cudatoolkit but I don't see /dev/nvidia-uvm and when I lsmod I don't see the kernel module either 20:35:15
@apache8080:matrix.orgapache8080looks like it gets loaded after I run nvidia-smi20:37:51
@apache8080:matrix.orgapache8080weird20:37:53
@apache8080:matrix.orgapache8080 Guess I can just have it load via the boot.kernelModules 20:43:18
@connorbaker:matrix.orgconnor (he/him)That is odd -- I can say I've never had that problem, though I only ever use headless and this config: https://github.com/ConnorBaker/nixos-configs/blob/19f532114a86099795c21b6b5026cf25a42a4053/modules/nvidia.nix#L15-L2023:32:49
@philiptaron:matrix.orgPhilip Taron (UTC-8)Hey -- who here will I see in 🇨🇭 at NixCon!?23:35:08
@connorbaker:matrix.orgconnor (he/him)I'll be at Nix Con23:52:35
@philiptaron:matrix.orgPhilip Taron (UTC-8)Hell yeah23:53:08
@philiptaron:matrix.orgPhilip Taron (UTC-8) I am planning on having a table with a sign:

23:53:35
