Model folder {ENC_MODELS_DIRT} doesn't exist.

Error message

Model folder {ENC_MODELS_DIRT} doesn't exist.

What it means

Import-time guard in mkgui/preprocess.py for the encoder models directory (ENC_MODELS_DIRT); the page builds an encoders Enum from *.pt files there. Missing folder raises at import.

Solutions

1. Create the encoder models directory and copy the encoder .pt checkpoint in
2. Download the pretrained models bundle to the expected location
3. Verify ENC_MODELS_DIRT in config

Example fix

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

enc_dir = Path(ENC_MODELS_DIRT)
if not enc_dir.is_dir() or not list(enc_dir.glob('*.pt')):
    raise SystemExit(f'Encoder models missing in {enc_dir}')

When it happens

Trigger: Loading the preprocessing page with no encoder models directory at the configured path.

Common situations: Pretrained encoder not downloaded; models stored under a renamed directory; fresh environment.
