Model folder {EXT_MODELS_DIRT} doesn't exist.

Error message

Model folder {EXT_MODELS_DIRT} doesn't exist.

What it means

Import-time guard in mkgui/train_vc.py: the VC training page requires an extractor models directory (EXT_MODELS_DIRT) with .pt checkpoints for its dropdown; missing folder raises at import.

Solutions

1. Create the extractor models directory and add an extractor .pt checkpoint
2. Download pretrained VC extractor weights
3. Verify EXT_MODELS_DIRT in config

Example fix

# before: extractor/saved_models missing
mkdir -p extractor/saved_models && cp extractor.pt extractor/saved_models/
# after: 'Loaded extractor models: 1', page loads

ext_dir = Path(EXT_MODELS_DIRT)
if not ext_dir.is_dir() or not list(ext_dir.glob('**/*.pt')):
    raise SystemExit(f'Extractor models missing in {ext_dir}')

When it happens

Trigger: Opening the VC training page with no extractor models directory present.

Common situations: No extractor pretrained model downloaded yet; models root misconfigured.
