I don't quite understand why it requires a password on a private computer.
I tried doing the obvious, something like this:
DEFAULT_MODEL_PATH = r"C:\Users\name\.cache\huggingface\hub\models--bosonai--higgs-audio-v2-generation-3B-base"
DEFAULT_AUDIO_TOKENIZER_PATH = r"C:\Users\name\.cache\huggingface\hub\models--bosonai--higgs-audio-v2-tokenizer"
And it appears that the functions are looking for the immediate path to the five or so model bits it's looking for, not simply a tree directory. I didn't see where they're all actually loaded up directly, from the looks of it, somewhere in HiggsAudio's files, looks like you imported a class or some such?
