Rasa 查找表在训练数据中抛出错误 - “不是有效的 NLU 数据”

Question

我正在使用 RASA 构建一个天气机器人，并希望我的模型能够将位置提取为实体。我的模型无法识别训练数据之外的位置。所以，我决定为其他实体使用查找表。

我按照博客文章 Entity extraction with lookup tables 并使用查找表通过在数据文件夹下创建查找“.txt”文件来识别训练数据中的位置实体。

这就是我的训练数据的样子：

{
  "rasa_nlu_data": {
    "lookup_tables": [
    {
        "name": "location",
        "elements": "data/location.txt"
    }
]
    "common_examples": [
      {
        "text": "Hello",
        "intent": "greet",
        "entities": []
      },
      {
        "text": "goodbye",
        "intent": "goodbye",
        "entities": []
      },
      {
        "text": "What's the weather in Berlin at the moment?",
        "intent": "inform",
        "entities": [
          {
            "start": 22,
            "end": 28,
            "value": "Berlin",
            "entity": "location"
          }
        ]
      },
      {
        "text": "hey",
        "intent": "greet",
        "entities": []

          }
        ]
      }
    ]
  }
}

我的查找表在一个新行中包含每个位置的名称。

但是，当我运行 'rasa train nlu' 时，我收到以下错误：“Path 'data' does not contain valid NLU data in it. Please verify the data format. The NLU model training现在将被跳过。“可能是什么原因？我只做了博客里说的。请告诉我哪里出错了。提前致谢

这实际上与查找无关，通过加载您的数据，我可以看到您在查找和常见示例之间缺少逗号，它应该如下所示：

{
  "rasa_nlu_data": {
    "lookup_tables": [
    {
        "name": "location",
        "elements": "data/location.txt"
    }
],
    "common_examples"
...

这表明您可能正在手动编写/编辑 json；如果需要，可以考虑使用 markdown 并使用 rasa data convert 获取 json
