@connorbaker:matrix.orgconnor (he/him)Ugh, haven't had as much time as I'd like to work on CUDA stuff. I've been trying to make a copy of the sample galleries dpreview has before Amazon yeets them into the abyss.04:29:24

@ss:someonex.netSomeoneSerge (matrix works sometimes)I have to be mostly absent myself too17:37:51
@ss:someonex.netSomeoneSerge (matrix works sometimes)What's the "sample galleries dpreview"?17:38:12
@ss:someonex.netSomeoneSerge (matrix works sometimes) Mood: start adding gpu tests to passthru in nixpkgs, marked with some requriedSystemFeatures that nobody else would have, like requiredSystemFeatures = [ "cuda" ]. And then run builders labeled system-features = cuda ... and endowed with extra-sandbox-paths = /run/opengl-driver/lib /dev .... 18:51:54
@ss:someonex.netSomeoneSerge (matrix works sometimes)We've got to start rolling these out at some point, and I'm rather convinced that the only sustainable way to maintain this stuff is intree18:53:17
@atrius:matrix.orgmjlbachDoes that not run into the license issue?18:56:29
@ss:someonex.netSomeoneSerge (matrix works sometimes)hwy would it18:56:41
@atrius:matrix.orgmjlbachOr is that fixed by the new driver situation?18:56:40
@atrius:matrix.orgmjlbachOh I remember in-tree builds were blocked by lack of clarity around redistributing cuda circa ~2 years ago18:57:03
@ss:someonex.netSomeoneSerge (matrix works sometimes)Yes, and hydra still does not build cuda packages18:57:25
@ss:someonex.netSomeoneSerge (matrix works sometimes)Which is why we have https://app.cachix.org/cache/cuda-maintainers18:57:35
@atrius:matrix.orgmjlbachOh so you just don't run the test on hydra18:58:16
@ss:someonex.netSomeoneSerge (matrix works sometimes)Yup, we'll just run them by ourselves for now18:58:33
@ss:someonex.netSomeoneSerge (matrix works sometimes)And if/when the redistribution situation and such finally becomes clearer, we can try and raise the hydra subject again18:59:10

@ss:someonex.netSomeoneSerge (matrix works sometimes)And how much storage is that?22:01:37

@ss:someonex.netSomeoneSerge (matrix works sometimes)I'm sorry, I've just got to complain again. Nixpkgs-review stalled by VoiceOfFaust?.. I'm not even going to check, I'm 100% certain it consumes gstreamer and is rebuilding because of opencv Oh teach me the magic of grafts01:50:12
@jovulic:matrix.orgj8c changed their display name from jv to j8c.02:21:27
@connorbaker:matrix.orgconnor (he/him) Somewhere in the range of 1-2TB so doable thankfully 05:03:32

In reply to @FRidh:matrix.org
Yes, I think this was based on https://github.com/NixOS/rfcs/pull/3

I found https://github.com/NixOS/nixpkgs/blob/master/pkgs/build-support/replace-dependency.nix but 1) I'm not sure if it would help to avoid rebuilds of transitive dependencies, 2) it doesn't work in pure mode? o_0

❯ nix eval .#chromium.outPath
error: 'builtins.storePath' is not allowed in pure evaluation mode

@ss:someonex.netSomeoneSerge (matrix works sometimes)I dumped my pathetic attempt of a patch here: https://github.com/SomeoneSerge/nixpkgs/pull/1/files09:44:06
@ss:someonex.netSomeoneSerge (matrix works sometimes) Kevin Mittman: do you know if libnvcuvid.so is in any way hardware-dependend/should actually come with the driver? Asking because currently the only derivation in nixpkgs that ships it is linuxPackages.nvidia_x11, as far as I can see 15:09:23

Jeez
23:09:20
@hexa:lossy.networkhexaevery tensorflow release ever? 😄23:10:06
@ss:someonex.netSomeoneSerge (matrix works sometimes)
In reply to @hexa:lossy.network
every tensorflow release ever? 😄
afaiu what's need is "just" to update tf?
