No encoder models found in %s

Error message

No encoder models found in %s

What it means

Raised by the Toolbox UI when populating model dropdowns: the encoder models directory contains zero *.pt files. Unlike the mkgui guards this triggers even when the folder exists but is empty, and it hard-crashes the toolbox (called from reset_ui at startup).

Solutions

1. Put at least one encoder .pt checkpoint directly in the encoder models directory
2. Re-check the 'models directory' setting in the Toolbox UI / config and point it at the folder that actually contains encoder .pt files
3. Re-extract the pretrained models archive, preserving directory structure

Example fix

# before: encoder models dir empty
 cp ~/Downloads/encoder.pt  /path/to/encoder/saved_models/
# after: toolbox starts, encoder dropdown lists 'encoder'

from pathlib import Path

def has_models(d: Path, pattern: str = '*.pt') -> bool:
    return d.is_dir() and len(list(d.glob(pattern))) > 0

assert has_models(encoder_models_dir), f'No encoder .pt files in {encoder_models_dir}'

try:
    ui.populate_models(...)
except Exception as e:
    show_dialog(str(e)); sys.exit(1)  # keep toolbox from hard-crashing silently

When it happens

Trigger: Starting the Toolbox (in normal or VC mode) with an encoder models directory that exists but has no .pt checkpoints (or pointing at the wrong directory).

Common situations: User downloaded models but left checkpoints in Downloads/zip; models placed one level too deep or with wrong extension; folder created but empty.
