如何返回分类与数值指标

def numerical_metric(inputs: dict, outputs: dict, reference_outputs: dict) -> float:
    # Evaluation logic...
    return 0.8
    # Equivalently
    # return {"score": 0.8}
    # Or
    # return {"key": "numerical_metric", "score": 0.8}

def categorical_metric(inputs: dict, outputs: dict, reference_outputs: dict) -> str:
    # Evaluation logic...
    return "english"
    # Equivalently
    # return {"key": "categorical_metric", "score": "english"}
    # Or
    # return {"score": "english"}
