I have read many posts saying policy has been changed and when I updated policy then it was showing coroutines are not iterable then I used asyncio but then it was showing that this event loop is already running(see the first post) but I’m not able to solve this issue . Please suggest sample code or exact changes I need to do in this code. rasa==1.1.7 rasa-sdk==1.1.0 python=3.6 ---

Hi @ashish, are you running in a jupyter notebook? if so please follow the beginning instructions [here](https://rasa.com/docs/rasa/master/api/jupyter-notebooks/) to avoid the event loop problem ---

Yes , I am working in a jupyter notebook. from this instructions , I have to add only these lines . import nest\_asyncio nest\_asyncio.apply() print(“Event loop ready.”) Right? I am a beginner ,Anything I missed? ---

Well you have to `pip install nest_asyncio` in the environment before launching the notebook, or alternatively try to do it from within the notebook, i think `! pip install nest_asyncio` should do it.
