| connor (he/him) | hope to have tensorrt version bump up tomorrow... but that also involves bumping onnx-tensorrt, tensorrt-oss, and a few other things simultaneously :F | 04:45:45 |
| connor (he/him) | while building every combination of TensorRT 10.x and CUDA release on x86_64-linux to verify I could remove cudnn and nvrtc as buildInputs I prodded Claude to make the optuna+helion thing I mentioned earlier: https://github.com/ConnorBaker/helion/blob/claude/enhance-helion-autotuner-01V2JcV61tYZPi7y6cuZpE54/helion/autotuner/optuna_search.py
It doesn't work with the version of Helion we have in Nixpkgs because of some API changes to parallel_benchmarking but it seems like what I wanted. Haven't had the chance to mess with it though :l | 04:50:08 |

| connor (he/him) | SomeoneSerge (back on matrix) I updated https://github.com/NixOS/nixpkgs/pull/459416 please merge | 02:57:01 |
| connor (he/him) | 🤦♂️ | 15:37:52 |
| connor (he/him) | https://github.com/onnx/onnx-tensorrt/pull/1043 moved from the pycuda to cuda python package and documented it nowhere I've been able to find | 15:38:34 |
| connor (he/him) | Kevin Mittman (UTC-7): the entry for --verbose seems to be for --no-dry-run, which doesn't have an entry: https://docs.nvidia.com/cuda/cuda-compiler-driver-nvcc/#verbose-v | 18:12:52 |
| connor (he/him) | well, pycuda's tests exposed a few issues with how NVCC works
notably that it dies if GCC isn't on the path -- it doesn't even use the path modifications from nvcc.profile | 18:38:12 |
| connor (he/him) | so this is now a larger PR https://github.com/NixOS/nixpkgs/pull/465047 | 18:38:20 |
| connor (he/him) | I'm going to split out the NVCC changes to a different PR and make pycuda a stacked PR | 18:51:51 |
| connor (he/him) | :F | 18:51:53 |

 yorik.sar | Finally got around to doing this: https://github.com/NixOS/nixos-homepage/pull/1903 - connor (burnt/out) (UTC-8) SomeoneSerge (back on matrix)Gaétan Lepage feel free to approve :) | 15:01:30 |
| yorik.sar | I guess I’ll make another one for nixos-cuda.org :) | 15:05:22 |
| yorik.sar | Here it is: https://github.com/nixos-cuda/nixos-cuda.org/pull/2 | 15:12:12 |

 matthewcroughan | Is there anybody that knows how you add cuda stuff to a rust build? | 01:54:22 |
| matthewcroughan | I have a rust build that is silently doing nothing when cuda isn't present, and not indicating in logs when it is being used or isn't | 01:54:37 |
| matthewcroughan | Leads to https://github.com/alvr-org/ALVR/issues/2792 | 01:55:02 |
 SomeoneSerge (back on matrix) | idk is it even about cuda? Any failing dlopens? @matthewcroughan:defenestrate.it: | 04:30:26 |
| matthewcroughan | I'm not sure, what do you think based on the issue? | 16:12:46 |
| matthewcroughan | Apparently people can get it to work by steam-run'ing the stuff they provide via github releases | 16:13:09 |
| SomeoneSerge (back on matrix) | Id_debuuuuuuuuuuuug | 16:49:33 |
| matthewcroughan | Yeah I can also get it working by steam-run'ing the github release | 17:01:30 |
| matthewcroughan | compiling onnxruntime takes forever though | 17:01:35 |
| matthewcroughan | so I'm doing that whilst compiling what I think could be a fix | 17:01:42 |
| 1 Dec 2025 |
| connor (he/him) | Make sure you’re setting config.cudaCapabilities explicitly to speed up compilation | 12:39:34 |
