espnet3.demo.pack.pack_demo

source

espnet3.demo.pack.pack_demo(system) → Path

Package demo assets and configs into a self-contained demo directory.

This prepares a runnable demo folder (typically <exp_dir>/demo) by: : - Resolving and copying the inference config into config/infer.yaml.

• Writing a resolved demo.yaml with paths made demo-relative.
• Copying additional files configured under demo_config.pack.files.
• Creating app.py / requirements.txt (via espnet3.demo.setup.setup_demo_assets()).
• Creating a minimal README.md when missing.

• Parameters:system – System object that provides (at minimum) demo_config and demo_config_path attributes. Typically an ESPnet3 system instance.
• Returns: Path to the created demo directory.
• Return type: Path
• Raises:
  • RuntimeError – If system.demo_config is missing or required files (e.g., inference config) cannot be resolved.
  • ValueError – If the demo config does not define a supported inference provider or does not include infer_config.

Example

>>> demo_dir = pack_demo(system)
>>> (demo_dir / "demo.yaml").exists()
True

Notes

• The output directory defaults to <system.exp_dir>/demo when configured, otherwise ./demo.
