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/preprocess.py: the preprocessing page requires an extractor models directory (EXT_MODELS_DIRT) containing .pt files to build its extractors dropdown; absence raises immediately when the module loads.

Solutions

1. Create the extractor models directory and add an extractor .pt checkpoint
2. Download pretrained extractor weights to the expected path
3. Check EXT_MODELS_DIRT configuration

Example fix

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

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 mkgui preprocessing page (or importing preprocess.py) with no extractor models directory present.

Common situations: Running preprocessing before any extractor model was trained/downloaded; misconfigured models root path.
