Hi everyone! I am looking at a bug we have with CDI (Container Device Interface, for forwarding GPU's to containers): https://github.com/NixOS/nixpkgs/issues/397065

I think the user has a correct configuration (unless there are settings that were not mentioned in the issue), my main question is when using the datacenter driver, why the nvidia-container-toolkit is reporting:

ERRO[0000] failed to generate CDI spec: failed to create device CDI specs: failed to initialize NVML: ERROR_LIBRARY_NOT_FOUND

Do you have any idea on why NVML would not be present in this environment?

HI! I've a small announcement to make.

I've been failing badly to keep up with the backlog as a maintainer, even though I'm recently able to spend some more time on Nixpkgs&c. Working in occasional 1:1 meetings, otoh, has always felt comparatively productive. We've just had another call with Gaétan Lepage and I find it was nice, so I now want to try the following: https://md.someonex.net/s/9S4E00sIb#

This is not exactly "official", I'm not posting this e.g. on Discourse until I'm more confident, but as such it's an open invitation.

@glepage:matrix.orgGaétan Lepage Indeed, it was great! We were able to finally finish fixint mistral-rs's cuda support! 15:24:02

@ss:someonex.netSomeoneSerge (back on matrix) connor (he/him) (UTC-7): did you use something like josh for cuda-legacy? I suspect this produced at least a few pings 😅 13:35:27
@connorbaker:matrix.orgconnor (he/him)I used https://github.com/newren/git-filter-repo — what would have pinged people?13:37:06

@ereslibre:ereslibre.socialereslibreHi! Given https://github.com/NixOS/nixpkgs/pull/362197 had conflicts recently due to the treewide formatting I closed it, and reopened it at https://github.com/NixOS/nixpkgs/pull/398993. I think we can merge this one too21:24:34
@ereslibre:ereslibre.socialereslibreWe have been going back and forth with the author for a while, and I thought it would be good to go ahead on our side21:25:10
@ereslibre:ereslibre.socialereslibreThanks!21:29:32
