| Shiroki Satsuki | Hello, I'm using shell.nix with Arch Linux, and I'm trying to use python310Packages.pycuda in my Python project, but when I import pycuda.driver, Python complained about missing of libcuda.so.1 | 18:04:05 |
| Shiroki Satsuki | Is this package only available in NixOS? Or do I need some setup to link my host libcuda.so.1 into shell.nix? | 18:05:57 |

 tpw_rules | if you are not using nixos you need nixGL: https://github.com/guibou/nixGL for cuda to work | 18:11:11 |
| tpw_rules | (and other graphics stuff) | 18:11:24 |
| Shiroki Satsuki | Thanks, I only know that nixGL is needed for OpenGL and Vulkan | 18:13:42 |
 SomeoneSerge (matrix works sometimes) | libcuda.so.1 comes with your nvidia driver, and applications built with nix expect driver-related libraries to be available in /run/opengl-driver/lib; you could use nixGL as suggested, or you could try symlinking your system's nvidia libraries into that directory (although it's not always guaranteed to work) | 18:16:10 |
| SomeoneSerge (matrix works sometimes) | As mentioned in the thread, you'd need to add a "8.2.4" attribute in cudnn/extension.nix like in this diff and ensure that "11.6" is listed among supportedCudaVersions
This should introduce in nixpkgs an attribute cudaPackages_11_6.cudnn_8_2_4
| 18:22:27 |
| SomeoneSerge (matrix works sometimes) | And onnxruntime-gpu support in nixpkgs sounds exciting, I really hope you make something out of it | 18:24:40 |

| iopq | I just found it from this page | 09:40:09 |

|  CRTified (old handle) left the room. | 10:43:28 |
| iopq | how do I install a different cuda toolkit version | 12:55:26 |
| tpw_rules | for what? | 22:47:45 |
| tpw_rules | you can use like cudatoolkit_11_5 instead of just cudatoolkit | 22:48:00 |
| 31 Dec 2022 |
| iopq | ah, I see, because different programs have different version requirements, CUDA is often like that | 04:19:53 |
| iopq | But maybe I should approach the problem from another end, what's the recommended way to run stable diffusion on NixOS? | 04:24:16 |
