source

espnet3.demo.resolve.resolve_runner_class(demo_cfg, infer_cfg: DictConfig | None = None)

Resolve inference runner class from infer.yaml or convention.

Resolution order: : 1. infer_cfg.runner.target (or runner_class) if present. 2. Convention-based path using demo_cfg.system.

Conventions assume: : espnet3.systems.<system>.inference.InferenceRunner exists.

• Parameters:
  • demo_cfg – Demo configuration object.
  • infer_cfg – Inference config object (optional).
• Returns: Runner class object, or None if no system is defined.

Example

>>> from omegaconf import OmegaConf
>>> cfg = OmegaConf.create({"system": "asr"})
>>> resolve_runner_class(cfg)
