解决方案

首先，由于您没有提供任何slot_mapping，它将默认将插槽映射到同名实体。您没有任何flight_from实体，因此这不起作用。您可以为此目的使用实体角色slot_mapping，并包括.

def slot_mappings(self) -> Dict[Text, Union[Dict, List[Dict]]]:
    """A dictionary to map required slots to
        - an extracted entity
        - intent: value pairs
        - a whole message
        or a list of them, where a first match will be picked"""

    return {
        "flight_from": self.from_entity(entity="location", role="from"),
...
    }

您还应该检查其他插槽的 slot_mappings 并考虑要使用什么逻辑来获取该信息。我建议您阅读在此处填写表格空位的不同方式
