Model folder {EXT_MODELS_DIRT} doesn't exist.

Error message

Model folder {EXT_MODELS_DIRT} doesn't exist.

What it means

Startup guard in the voice-conversion GUI (mkgui/app_vc.py) for the extractor models directory (EXT_MODELS_DIRT). The module builds an extractors Enum from '**/*.pt' files under that folder at import time; an absent folder aborts app startup.

Solutions

1. Create the extractor models directory and put at least one .pt extractor checkpoint in it
2. Download the pretrained VC model bundle and extract it into the expected location
3. Verify EXT_MODELS_DIRT in config matches your checkpoint layout

Example fix

# before: extractor/saved_models missing
mkdir -p extractor/saved_models
cp extractor.pt extractor/saved_models/
# after: 'Loaded extractor models: 1' and app starts

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: Starting app_vc.py without a trained/downloaded PPG extractor model directory at the expected path.

Common situations: Voice-conversion pretrained models not downloaded; fresh clone; models stored under a different root than the config constant.
