Hello, nix is still building cuda even though I setup cuda-maintainers. This must mean that your particular revision wasn't cached | 18:37:41 |

This must mean that your particular revision wasn't cached I didn't select a version 🤪 | 18:38:11 |
| caniko | how do I do that? and what is latest? | 18:38:22 |

| caniko | * how do I do that? and what is latest on cache? Can I do it so that I am always on latest? | 18:38:51 |
| SomeoneSerge (back on matrix) | The last I see in the logs is https://github.com/SomeoneSerge/nixpkgs-cuda-ci/commit/997229a3acb24e73898da3286a2e0caeb81bc918#diff-216b2b7bfde9416c79d133bacb031e95702a20bdedb548c0b055c837aa4f6a9cR68
The maintainers' cache is in a low maintenance mode right now. If you're willing you can try the nix-community cachix, but please note that their cuda jobset isn't officially stabilized yet and can be pulled out at any moment. Both caches are provided with out any obligations, etc, etc, etc | 18:43:53 |

| SomeoneSerge (back on matrix) | Something like nix flake lock --update-input nixpkgs github:NixOS/nixpkgs/$commitid if I'm not mistaken | 19:11:09 |
| SomeoneSerge (back on matrix) | or is it nix flake update --update-input? | 19:11:23 |
| caniko | but will nix flake update --update-input automatically start using cachix? | 19:14:44 |
| SomeoneSerge (back on matrix) | This is unrelated to cachix, this just pins a different nixpkgs version. When nix "builds" a derivation it looks at whether its inputs are available, and if not it builds or substitutes them, recursively. Which substituters to use (including cachix) is a global nix configuration. | 19:19:35 |
| SomeoneSerge (back on matrix) | So if you pick a particular nixpkgs commit and look at its pytorch, it'll correspond to a hash, and if the substituter (cachix) says it knows this hash you'll end up downloading the prebuilt thing instead of running the expensive build | 19:20:33 |

 hacker1024 | I have updated the tensorflow-bin derivation to support Jetsons: https://github.com/NixOS/nixpkgs/pull/334996
In doing so, though, I made it use cudaPackages_12 instead of 11. I believe this is correct for x86_64 too. On the Jetson, at least, it cannot use CUDA 11 as it's hardcoded to dlopen CUDA 12. | 04:53:10 |
| SomeoneSerge (back on matrix) | ...-bin packages 😩 | 13:17:52 |
| SomeoneSerge (back on matrix) | Thank you | 13:17:54 |

...-bin packages 😩 Yeah I'd love to get TensorFlow building from source but it takes about 8 hours per build on my fastest AArch64 device | 04:34:43 |
| hacker1024 | We'll be getting | 04:34:53 |
| hacker1024 | * We'll be getting some Jetson AGX Orins soon so I might give it another shot then | 04:35:31 |

 Philip Taron (UTC-8) | I see there's cudaPackages_12_3 but not _12_4 or _12_5. My nvidia-smi output says 12.5; is there something I should be worried about or is it steady as it goes? | 14:49:22 |
| SomeoneSerge (back on matrix) | IIRC as long as cudaRuntimeGetVersion() <= cudaDriverGetVersion() and you're OK (nvidia-smi reports the latter, the former is what you link by runpaths in nixpkgs) | 15:04:10 |
