espnet3.publication.demo.packing.pack_demo(system) → Path

Package a demo into a self-contained directory ready for upload.

Reads system.demo_config and produces a directory that contains:

• demo.yaml: the resolved demo config with all paths rewritten to be relative to the output directory so the pack is portable.
• app.py: the Gradio launcher script specified by demo_config.ui.app_script.
• Any extra files listed in demo_config.pack.include.
• Optionally a description file referenced by demo_config.ui.description.

The output directory is determined in order of priority:

1. demo_config.pack.out_dir (explicit)
2. system.exp_dir / "demo"
3. Path.cwd() / "demo"

• Parameters:system – An ESPnet3 system instance with demo_config set.
• Returns: Path to the packed demo directory.
• Raises:
  • RuntimeError – If system.demo_config is None.
  • ValueError – If demo_config.model.dir_or_tag cannot be inferred.

Examples

>>> demo_dir = pack_demo(system)
>>> print(demo_dir)
/path/to/exp/demo
