运行 Rasa 时(在 1.3.3、1.3.7、1.3.8 版本上试用)我几乎每次拨打电话时都会遇到此超时异常消息。我正在运行一个简单的程序,它可以识别用户何时提供他们的年龄,并通过操作响应将年龄存储在数据库中:
Bot loaded. Type a message and press enter (use '/stop' to exit):
Your input -> I am 24 years old

最初我认为这个超时是由我的 Rasa 程序的另一部分使用大型查找表引起的,但是对于年龄识别,我使用了一个简单的正则表达式:
## regex:age
- ^(0?[1-9]|[1-9][0-9]|[1][1-9][1-9])$
甚至这也会导致超时。
请帮我解决这个问题。我什至不需要避免超时,我只想知道在哪里可以捕获/忽略此异常。
谢谢!
