v2.1: download_adapter reads downloaded file and writes bytes explicitly (kills symlink/makedirs trap); isfile+size assert kept
adb17c4 verified | """eval_joint2.py v2.1 — closed-loop eval of the POLISHED joint model (epoch2/checkpoint-900/lora). | |
| Standalone: no runtime patching; adapter path baked to ground-truth layout (verified via repo ls). | |
| Baked fixes: download via read-bytes + explicit write (immune to HF-cache symlink chains), | |
| isfile+size asserts after write, Whisper return_timestamps, safe drift aggregation, | |
| demo-exact generate. Env: ARMS (default "joint2"). Pushes to ACloudCenter/vibevoice-eval-jointv1. | |
| Prints EVAL DONE. | |

There was no off switch on the ocean.", | |

Same bedtime, same wake time.\nSpeaker 1: Even on weekends, which is where everyone cheats.\nSpeaker 2: That's exactly where I cheat.\nSpeaker 1: The researchers say your body doesn't know it's Saturday.\nSpeaker 2: My body absolutely knows it's Saturday.\nSpeaker 1: Apparently not, biologically speaking.\nSpeaker 2: Fine, I'll set an alarm for Sunday too.

She seemed okay about it, which surprised me.\nSpeaker 2: Thirty years behind that counter and she seemed okay?\nSpeaker 1: Maybe she's more practical than sentimental.\nSpeaker 2: I'm going to miss walking past that smell every morning.\nSpeaker 1: Delivery still smells. It just doesn't linger.", | |

The hinges were stripped, not the frame, which saved me a full rebuild.\nSpeaker 2: How long did that take?\nSpeaker 1: Four hours, two of which were finding screws that actually fit.\nSpeaker 2: The hardware store run is always the real project.\nSpeaker 1: Two trips. One for the wrong screws, one for the right ones.\nSpeaker 2: Classic. Did you paint it?\nSpeaker 1: Not yet. The wood needs to dry out first, apparently.\nSpeaker 2: So the project continues.\nSpeaker 1: The project continues. But the door closes now, which is more than March could say.", | |
