@koutensky:matrix.nesad.fit.vutbr.czMichal Koutenský * The wheel in the archive is called tensorrt-10.3.0-cp312-none-linux_x86_64.whl, so not sure what's going on 15:14:31

@connorbaker:matrix.orgconnor (burnt/out) (UTC-8) Michal Koutenský: try manually unpacking and verifying the tarball has it at the same path its expecting; also try adding an echo with the current directory in the derivation to make sure the script is printing where its searching from 14:58:01
@koutensky:matrix.nesad.fit.vutbr.czMichal Koutenskýthe tarball has it without the last version number (.26). i managed to get it working yesterday by modifying the unpack phase to extract the correct wheel. is there a chance nvidia changed how the tarball contents look and no one caught it yet? if i had a different tarball i assume the hashes wouldn't match with what is at https://github.com/NixOS/nixpkgs/blob/nixos-24.11/pkgs/development/cuda-modules/tensorrt/releases.nix, but since the build process needs manual intervention i assume there's not much automation for it nor do many people use it15:04:09
@koutensky:matrix.nesad.fit.vutbr.czMichal Koutenskýlooking at the python package, the listed maintainer only had one commit for it in 202215:05:33
@justbrowsing:matrix.orgKevin Mittman (jetlagged/UTC-7)TRT 10.3 is pretty old18:17:09
@stick:matrix.orgstick Michal Koutenský: i recommend you to use CUDA stuff from master/nixpkgs-unstable - many fixes go there and are not being backported to stable (24.11) 18:35:39
@stick:matrix.orgstickfor example I updated TRT to 10.8 there (and there is already 10.9, yay)18:36:04
@stick:matrix.orgstickbtw, zdravim do Brna :D18:36:36
@koutensky:matrix.nesad.fit.vutbr.czMichal Koutenskýdoes the python package build though? i checked master (and issues/prs) yesterday and there doesn't seem to be anything significant https://github.com/NixOS/nixpkgs/commits/master/pkgs/development/python-modules/tensorrt/default.nix18:37:19
@koutensky:matrix.nesad.fit.vutbr.czMichal Koutenskýi guess i'll try building master and possibly move our stuff off 24.1118:37:42
@koutensky:matrix.nesad.fit.vutbr.czMichal Koutenskýa Brno zdraví naspäť :D18:37:53
@stick:matrix.orgsticki updated the package here https://github.com/NixOS/nixpkgs/commit/1609398c9def5a31bb7951c284cf21f45b981b39 the python-module is just a simple wrapper that does not need changes i guess18:38:45
