source

espnet3.utils.task_utils.save_espnet_config(task: str, config: Dict | DictConfig, output_dir: str) → None

Save an ESPnet2-compatible training config snapshot to disk.

This builds the full config by merging: : - The task’s default config

• The resolved model config (flattened into root keys)
• Selected dataset preprocessor config (flattened into root keys)
• Any remaining user-provided config keys

• Parameters:
  • task (str) – Dotted path to an ESPnet2 Task class.
  • config (Union *[*Dict , DictConfig ]) – Training config (OmegaConf or dict).
  • output_dir (str) – Output directory where config.yaml is written.
• Returns: None
• Raises:
  • RuntimeError – If the task class cannot be resolved.
  • OSError – If the output directory cannot be created or written.

Example

>>> save_espnet_config("espnet2.tasks.asr.ASRTask", cfg, "exp")
