DemoRuntime

Build demo runtime (model + runner wiring) from the demo config.

This resolves the inference provider/runner classes and builds the model via InferenceProvider.build_model(infer_cfg).

• Parameters:
  • demo_cfg – Loaded demo configuration (typically from demo.yaml).
  • demo_dir (Path) – Demo directory used to resolve relative paths.
• Returns: Runtime container holding the resolved model, runner class, : output mapping, and extra kwargs.
• Return type:DemoRuntime
• Raises:RuntimeError – If inference provider is not configured or infer_config is missing.

Example

>>> runtime = build_runtime(demo_cfg, Path("exp/demo"))
>>> runtime.model is not None
True
