If you are a developer, you should probably set this to at least`"versioned"`.

| Lun | Somehow the hash of cmake-build-preserve-PYTHONPATH changed between yesterday and today so torch is broken.
error: hash mismatch in fixed-output derivation '/nix/store/vywcjiyn0ix2yr132lvdb8wnqpcp0wyf-cmake-build-preserve-PYTHONPATH.drv':

| Lun | I could put up a quick PR to fix the hash but not sure that's right, it might just happen again. 😅 cc Gaétan Lepage | 17:29:01 |

| hexa | we don't have that, right? | 20:23:04 |
| hexa | and we don't have tflite either, so I patched frigate to use tensorflow.lite.python.interpreter intead of tflite_runtime.interpreter cut-out | 20:24:07 |

 Gaétan Lepage | It was great meeting (some of) you guys at NixCon!
Have you had a chance to look at the nix-community hydra situation connor (he/him) (UTC+2)? | 22:29:30 |
| connor (he/him) | I have not :( | 23:59:17 |

the nix-community hydra situation
Is there a problem with it?
| 01:12:32 |
| connor (he/him) | Gaétan had mentioned something about (I think, sorry brain is fuzzy from travel) no recent version of PyTorch, either from being outdated or from the build failing | 02:10:08 |
| Gaétan Lepage | Yes, I was talking about the nvidia (cudaSupport = true) jobset. I have the impression that I didn't get any cache-hits on these packages recently. | 08:28:11 |
| Gaétan Lepage | Maybe there is nothing wrong and we simply need to wait for nix-community's hydra to catch up. | 08:28:39 |
