 Sarah Clark | Riddle me this: python3Packages.accelerate builds fine on Linux, but fails on Darwin in Hydra (and in nixpkgs-review), but not in nix-build. The symptom is "cannot import from transformers.test-utils" during pytest. If I move transfoormers from nativeCheckInputs to checkInputs, the problem disappears. Any idea why? | 21:23:25 |

Does it really say test-utils? That isn't a valid module name | 21:31:34 |
| Sarah Clark | Sorry, that's from a different issue. The error is ImportError: cannot import name 'PretrainedConfig' from 'transformers.modeling_utils | 21:33:48 |

 Randy Eckenrode | For some reason, Mesa is hanging in install phase when running the megadriver script. | 01:09:11 |

 Lun | https://github.com/NixOS/nixpkgs/pull/496111 | 07:06:52 |
| Lun | I'm about to go to bed so if this is wrong or needs tweaked just edit the branch or do whatever | 07:07:36 |
 emily | should probably drop it from the blockers, I can't imagine anyone is using GTK Transmission on macOS... | 12:20:55 |
| Randy Eckenrode | Does “clang tidy” need clang-tools because wrappers? | 12:22:30 |
| Randy Eckenrode | New M5 Pro and Max CPUs feature super cores. Maybe autoconf finally won’t take forever to run. 🤪 | 15:23:47 |

That should be fixed when 1.94 releases next week? Think someone fixed it meanwhile | 15:25:14 |

FWIW I was building with
with (import ./. {}); {
inherit
hello
ispc
ghc
nodejs
boost
;
inherit (qt6Packages)
qtwebengine
;
}
Managed to build all these | 15:25:26 |

 hexa | when? we might need to buy new mac minis for infra sooner rather than later | 15:28:24 |
| hexa | Pricing remains uncertain as Apple shifts some production to Texas, potentially affecting costs alongside tariff and exchange rate fluctuations.
| 15:29:10 |
| Randy Eckenrode | Just announced new MBPs with them today. Ships next week. No news yet on new Minis. | 15:29:09 |

| hexa | hydra queue be like … 50k darwin, linux ~0 | 15:30:22 |
| hexa | that's how staging tends to look these days | 15:30:27 |
| Randy Eckenrode | Won’t that get better once we’re not building x86_64-darwin? | 15:30:52 |
| hexa | we tried to move some more m1 hardware the foundation has into prod but hit snags in multiple locations | 15:30:53 |
| hexa | somewhat | 15:30:57 |
| hexa | but we're also seeing bigger builds like firefox with lto | 15:31:06 |
