class espnet3.publication.demo.session.DemoSession(demo_dir: Path, demo_cfg: DictConfig, model: InferenceModel, registry: UIAssetRegistry)

Bases: object

Loaded demo runtime state for a packed demo directory.

This class keeps the packed demo config, resolved model, and asset registry together so recipe-local demo.py files can build any Gradio layout they want while still reusing ESPnet’s model loading and input/output wiring.

• Parameters:
  • demo_dir – Packed demo directory.
  • demo_cfg – Loaded packed demo config.
  • model – Loaded inference model.
  • registry – Asset registry for this demo session.

Initialize from already-loaded demo config, model, and registry.

build_input_component(spec: dict[str, Any]) → Any

Build one Gradio input component from a spec.

build_output_component(spec: dict[str, Any]) → Any

Build one Gradio output component from a spec.

create_inference_fn(input_specs: list[dict[str, Any]] | None = None, output_specs: list[dict[str, Any]] | None = None, input_keys: list[str] | None = None, output_keys: list[str] | None = None)

Return a callable that maps Gradio values to model inference.

• Parameters:
  • input_specs – Optional resolved UI input spec list.
  • output_specs – Optional resolved UI output spec list.
  • input_keys – Optional model input key list. When omitted, keys are derived from input_specs.
  • output_keys – Optional model output key list. When omitted, keys are derived from output_specs.
• Returns: Function suitable for gr.Button.click that maps UI values to model input keys and runs inference.
• Return type: Callable
