Error message

Model folder {CONV_MODELS_DIRT} doesn't exist.

What it means

Import-time guard in mkgui/train_vc.py for the convertor models directory (CONV_MODELS_DIRT), which must contain .pth convertor checkpoints; absent folder aborts module import.

Solutions

1. Create the convertor models directory and copy the .pth checkpoint in
2. Train or download the ppg2mel convertor to the expected path
3. Confirm CONV_MODELS_DIRT configuration

Example fix

# before: convertor/saved_models missing
mkdir -p convertor/saved_models && cp ppg2mel.pth convertor/saved_models/
# after: 'Loaded convertor models: 1', page loads

conv_dir = Path(CONV_MODELS_DIRT)
if not conv_dir.is_dir() or not list(conv_dir.glob('**/*.pth')):
    raise SystemExit(f'Convertor models missing in {conv_dir}')

When it happens

Trigger: Opening the VC training page when the convertor models folder does not exist.

Common situations: ppg2mel convertor not trained/downloaded; checkpoints saved under another root; wrong file extension.
