I can have a look on Saturday, if no one takes over before then. I hope someone takes over

Hi all, not sure if this is the best place to ask, but I've been trying for the past hour or two to get tensorflowWithCuda using the cached version with 0 success

Is there any specific nixpkgs tag that is build in the cache? Right now I'm using nixos-unstable, specifically commit 3ad64d9e2d5bf80c877286102355b1625891ae9a. I have a flake.nix with a devShell containing

buildInputs = [
  (python3.withPackages (p: with p; [ tensorflowWithCuda ]))
];

But it will not use any cached version (and, as far as I can tell, it's not actually cached? It's trying to compile nccl, which I have left running for over an hour and it still compiled, a dry-run reveals the hash for that is 87kylkr9cszpzmf9iv6p705a2g43zzaq, which using the curl method to see if it's on cachix reveals that it is, in fact, not in there... what am I missing?

@ss:someonex.netSomeoneSerge (matrix works sometimes)Hi! The build history: https://hercules-ci.com/github/SomeoneSerge/nixpkgs-unfree 11:54:27
@ss:someonex.netSomeoneSerge (matrix works sometimes)Last 2 or 3 days are missing because of one particularly heavy nixpkgs-review xD11:55:05

Hi! The build history: https://hercules-ci.com/github/SomeoneSerge/nixpkgs-unfree
so i have a weird issue then, if i use just nccl it fetches from cache, but tensorflowWithCuda wil lcompile it from sctach
11:55:29
@pta02:matrix.orgPedro Alvesbut i'll check out an older commit and report back in a bit11:55:42
@ss:someonex.netSomeoneSerge (matrix works sometimes)I think this is the last build of nixos-unstable and it has many failures: https://hercules-ci.com/github/SomeoneSerge/nixpkgs-unfree/jobs/3653 11:56:14
@pta02:matrix.orgPedro Alvesalright i'll look for a successful one11:56:47

11:58:03
@pta02:matrix.orgPedro Alveslet's try that out then11:58:56
@ss:someonex.netSomeoneSerge (matrix works sometimes)Ouch, sorry, looked in the wrong place. That was nixpkgs-unstable12:01:07

@pta02:matrix.orgPedro Alvesas long as it works :D this is just in a nix shell12:02:01
@ss:someonex.netSomeoneSerge (matrix works sometimes)Yea, just that I think nixpkgs-unstable was the more broken one xD12:02:23
@pta02:matrix.orgPedro Alvesit's building now and i saw a 'fetching cudatoolkit from https://cuda-maintainers.cachix'12:02:34

@pta02:matrix.orgPedro Alvesalright!12:15:41
@pta02:matrix.orgPedro Alves so, it's fetching everything except tensorflow-gpu 12:20:23
