Rasa core restaurantbot演示示例未按预期工作

Question

我正在学习rasa-core bot开发。为了理解目的，我从https://github.com/RasaHQ/rasa_core/tree/master/examples下载了rasa restaurant bot示例并按照文档中给出的步骤在本地运行该示例。下面是步骤

• python3 -m rasa_nlu.train -c nlu_model_config.json --fixed_model_name 电流
• python3 bot.py train-dialogue
• python3 bot.py run

之后提示

Bot loaded. Type a message and press enter :
Me-Hello
Bot-if you'd like to modify anything else, please tell me what
Me-moderately priced restaurant that serves creative food
Bot-if you'd like to modify anything else, please tell me what

对于几乎所有消息，机器人都在回复“如果你想修改其他任何消息，请告诉我什么 “ 此消息仅从训练数据集中选取。我没有自己输入任何内容。
