Error using ib_insync with Streamlit.io - 'There is no current event loop'

[d416]

There is a whole thread of people trying to get ib_insync to work within Streamlit without success. Error is 'There is no current event loop.' https://github.com/streamlit/streamlit/issues/744

Maybe we can get a code recipe for doing this in the ib_insync docs? (hopefully it's this simple)

[Anton-Filimoncev]

Add this code before import ib_insync:

import asyncio

def get_or_create_eventloop():
    try:
        return asyncio.get_event_loop()
    except RuntimeError as ex:
        if "There is no current event loop in thread" in str(ex):
            loop = asyncio.new_event_loop()
            asyncio.set_event_loop(loop)
            return asyncio.get_event_loop()

loop = asyncio.new_event_loop()
asyncio.set_event_loop(loop)

This is not specific to ib_insync but to any asyncio application.
