Question

我在Rasa中遇到一个奇怪的问题。当我删除某个动作名称或更改某个动作名称时。同时，我还删除了一些插槽。 Rasa将出现以下错误：

我删除的广告位“ mathcalc”和功能“ intent_calc_plus”以及操作“ action_calc_plus”。仅当我删除对话表时，以上错误才会消失。是什么原因？我无法在生产环境中删除对话表。

非常感谢！

好像我回答得有点晚了，但是在这里。

您收到此错误，是因为当用户重新启动与漫游器的对话时，rasa首先会检索与该用户之前的对话（称为tracker）。这意味着在上一个对话中，它具有插槽mathcalc。但是这一次，当它尝试填充插槽mathcalc时，它不能，因为这次它不存在。这就是您收到错误的原因。

这是跟踪器的外观：

{
 "sender_id": "2408196042602645",
  "slots": {
    "mathcalc": null,
    ...
  },
 "latest_message": {...},
 "events": [...]
}

要解决该问题，您应该使用新数据重新训练您的机器人，并且应该没问题。

当您删除conversations表时，此问题消失的原因是因为先前的对话不存在，因此它不会尝试重新创建最后的对话。

希望有帮助。

删除数据库对话后，Rasa错误消失了，为什么？
