Can you please format your question?

Edited . Could be please suggest something to solve this?. I have tried all the suggestion .

  • At which point does this exception happen?
  • Is this the stack trace or you code?

please check this code and suggest me what things i need to change. Its not working in my jupyter notebook . The training phase

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.

Hi @ashish, are you running in a jupyter notebook? if so please follow the beginning instructions here 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


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.
