 Robbie Buxton | * Oh you can definitely get something on a neocloud then, the best/cheapest one to changes month to month so probably worth having a bit of a Google. | 15:58:40 |
| Robbie Buxton | Amazon is fine but more expensive | 15:58:47 |
| Robbie Buxton | I think nvidia brev is also pretty good and cloud agnostic | 15:59:14 |
 ethancedwards8 | Cool, thanks! I appreciate the help | 16:21:09 |

| Diamo | torch-bin 2.11 doesn't come with cudnn 9.19.0??? | 01:14:20 |

 Gaétan Lepage | We just bumped torch-bin to 2.12 (but it requires CUDA>=13.0). What issue are you facing exactly | 10:28:47 |

| Diamo | im still using torch-bin 2.11 and it requires cudNN 9.19.0 but i have 9.13.0 (from 25.11?) issue being that theres no nixpkgs commit where I can fix the 2.11 issue | 10:57:58 |

 Wahid Khan | does torch-bin 2.12 require that cudaPackages be cudaPackages13x? | 06:06:55 |
| Wahid Khan | when I try to add torch-bin it complains that cudaPackages is 12.9 and 13+ is required. even if my flake uses cudaPackages132 | 06:07:34 |
| Wahid Khan | working around it with an overlay to set cudaPackages = cudaPackages132 | 06:08:04 |

| Gaétan Lepage | Here is the overlay you need:
(final: prev: {
cudaPackages = prev.lib.recurseIntoAttrs prev."cudaPackages_13_2";
})
| 07:14:40 |
| Wahid Khan | yep, doing something similar | 07:22:02 |
| Diamo | oh yeah i figured it out too, using cues packages_13_1 with nixpkgs pinned to commit 461de5c011cdf1015d26f7a5c9f4a25404e6d90e (not using flakes) | 15:02:02 |

| ethancedwards8 | are there some tasks that just need manpower/time/hours in nixpkgs cuda right now? my company is paying for me to have gpu access to an nvidia t4 so i have proper hardware access. is this a good place to start? https://github.com/NixOS/nixpkgs/issues/232501 | 20:26:09 |

 connor (he/him) | I mean maybe?
Aside from difficulties with the package ecosystems as a whole for the ML stack and the absurd amount of domain knowledge required to be productive in contributing fixes or improvements, a lot of the packaging woes are caused by foundational components of Nixpkgs which need to be generalized or fixed.
That’s what I’ve been thinking about most; there’s a bunch of old tickets that need to be updated and general housekeeping we need to do; if you have the bandwidth to find and make a comment on the ticket about any other users that haven’t migrated, I’d appreciate it! | 04:25:14 |
| Gaétan Lepage | I have a gigantic todo list too, mostly around DL and/or Python stuff. We can chat about things you would be interested in helping with if you want :) | 05:51:48 |

| ethancedwards8 | Yes! I would love to. Definitely interesting in helping package whatever CUDA libraries are needed + improving Python support. | 03:00:26 |
| ethancedwards8 | But yes I’ll try to look through all the CUDA tickets and see what I can get up to :) always looking for more Nixpkgs projects | 03:01:13 |
