Model folder {VOC_MODELS_DIRT} doesn't exist.

Error message

Model folder {VOC_MODELS_DIRT} doesn't exist.

What it means

Startup guard in mkgui/app_vc.py for the vocoder models directory (VOC_MODELS_DIRT), globbing '**/*gan*.pt' for vocoder checkpoints. Missing folder aborts the app at import time.

Solutions

1. Create the vocoder models folder and place a *gan*.pt checkpoint inside
2. Download the pretrained vocoder and extract to the expected path
3. Verify VOC_MODELS_DIRT in the config

Example fix

# before: vocoder/saved_models missing
mkdir -p vocoder/saved_models
cp hifigan_v1.pt vocoder/saved_models/
# after: app import succeeds

voc_dir = Path(VOC_MODELS_DIRT)
if not voc_dir.is_dir() or not list(voc_dir.glob('**/*gan*.pt')):
    raise SystemExit(f'Vocoder missing in {voc_dir}')

When it happens

Trigger: Starting the VC GUI when the vocoder models directory does not exist.

Common situations: Vocoder weights not downloaded for the VC pipeline; directory moved; models bundle extracted into a different root.
