that will only put ${libedgetpu.out}/bin into PATH sorry, I am dumb when it comes to these things, please bear with me. So do I not even need to have libedgetpu included in environment.systemPackages at all? | 23:55:06 |
 @hexa:lossy.network | load_delegate is a function provided by tensorflow that wants to load a shared library at runtime | 23:55:43 |
| @hexa:lossy.network | but since nixos does not store libraries in easily discoverable paths like /usr/lib or similar, we need some patching | 23:56:13 |
| netpleb | I see. That makes sense. So I need to apply the patch to frigate? (I'm using the nixos unstable module) | 23:57:32 |

https://github.com/NixOS/nixpkgs/pull/357717 whoa, you are amazing!!! ok I will test it and see what happens! | 00:01:14 |
| netpleb | really dumb question -- when you test something like this, what is you usual method? I figured I would just change my nixpkgs input from nixos-unstable over to that PR branch you just published. That pretty much what you do? | 00:02:30 |
| netpleb | sorry, maybe the better question is this: for home automation things, do you end up with multiple version of nixpkgs as inputs? Such as "nixpkgs-frigate" and "nixpkgs-home-assistant" so that you're able to bump along and pull in latest things? | 00:04:06 |
| @hexa:lossy.network | I would probably override the package | 00:04:14 |
| @hexa:lossy.network | https://search.nixos.org/options?channel=unstable&show=services.frigate.package&from=0&size=50&sort=relevance&type=packages&query=frigate.package | 00:04:47 |
| @hexa:lossy.network | so this option defaults to pkgs.frigate | 00:04:52 |
| @hexa:lossy.network | and you could in theory do the following | 00:04:59 |
| @hexa:lossy.network | { lib, pkgs, ... }:
{
services.frigate.package = pkgs.frigate.overrideAttrs (oldAttrs: {
patches = oldAttrs.patches or [ ] ++ [
(substituteAll {
src = ./libedgetpu.patch;
libedgetpu = "${lib.getLib pkgs.libedgetpu}/lib/libedgetpu.so.1.0";
})
];
});
}
| 00:06:29 |
| @hexa:lossy.network | and then drop the patch into the same directory | 00:06:47 |
| netpleb | In reply to @hexa:lossy.network
and then drop the patch into the same directory ok, I will try that, thanks! I have never done this type of patching. I presume I download the patch file from your github PR branch? | 00:08:36 |
| netpleb | oh, I am dumb, you mean that actual libedgetpu.patch file that you included within that PR | 00:09:16 |
| @hexa:lossy.network | yep | 00:11:34 |
| netpleb | hmm, close but we are missing something:

should it be lib.substituteAll? | 00:17:07 |
| @hexa:lossy.network | no, pkgs.substituteAll | 00:17:43 |
| netpleb | In reply to @hexa:lossy.network
no, pkgs.substituteAll interesting, apparently there is a lib.substituteAll as well ;) | 00:18:54 |
