如何仅通过 API 调用在 Rasa 中成功训练和替换模型？

问题描述

（帖子指的是 Rasa 2.4.0）

目的：当我启动本地rasa服务器时，我希望只使用http请求来替换当前正在运行的模型。我想这样做而不必关闭 rasa 服务器并重新训练模型。

尝试：一旦我启用了本地服务器，使用：

rasa run     -m models     --enable-api     --log-file out.log     -vv

当我通过运行以下命令尝试使用文档中的 PUT - replace the currently loaded model api 时：

curl -X PUT http://localhost:5005/model -H ‘Content-type: application/json’ --data-binary "@replaceModel.txt"

replaceModel.txt 文件在哪里

{
  "model_file": "models/20210423-144222.tar.gz","model_server": {
    "url": "http://localhost:5005/model/20210423-144222.tar.gz","wait_time_between_pulls": 0
  },"remote_storage": "aws"
}

所以它说模型已经成功加载。但是，一旦进行了此更改，我似乎无法与机器人通信。当我 ping 它时：

$ curl -XPOST localhost:5005/webhooks/rest/webhook -d '{"sender":"111","message":"hi"}'

[]

我从服务器收到以下提示：

在我运行 PUT replace loaded model 调用之前，当 rasa 服务器刚启动时，我尝试通过 ping 来与机器人通信：

$ curl -XPOST localhost:5005/webhooks/rest/webhook -d '{"sender":"111","message":"hi"}'

[{"recipient_id":"111","text":"Hello,this is the bot service,powered by Rasa. How Could I help?"}]

我已经使用 rasa interactive 单独测试了模型，并通过 -m 标志将特定模型提供给它。 “hi”输入应该有效。所以我认为我尝试更换模型的方式不正确，我不确定我能做些什么来解决这个问题。我能得到一些指导吗？谢谢。
