I run pne-chat after pip install promptulate. It shows the following error:

import paho is not a good way for developer. I think we should not import paho when initialization.

I think we can import paho when run the tool.

class IotSwitchTool(Tool):

    def _run(self, question: str, *args, **kwargs) -> str:
        import paho.mqtt.client as mqtt
        ...

API wrapper get the same problem. We should import package when run it.
