My training data has several examples with a newline inside When training I get the UserWarning: “…contains an example that doesn’t start with a ‘-’ symbol…” So it’s treating it as a new training example. Should I change the newline to \n?

Sure, here is an example:

```auto
- intent: greet
  examples: |
    - Hello
    - Hey
      how are you?

```

should this be changed to this?

```auto
- intent: greet
  examples: |
    - Hello
    - Hey\nhow are you?

```

Change to:

```auto
- intent: greet
  examples: |
    - Hello
    - Hey
    - how are you?

```

In YAML syntax for each training example you need to mention - hyphen and Its highly recommend to take an 10+ training example.

> - Hello
> - Hey\nhow are you?

It should be

```auto
- intent: greet
  examples: |
    - Hello
    - Hey how are you?

```

That’s it

You can even check the YAML syntax using this online tool [http://www.yamllint.com](http://www.yamllint.com)

So how does rasa treat new line in incoming messages?
