# RuntimeError: asyncio.run() cannot be called from a running event loop in Jupyter
## What's going on
Running the Hume streaming example in a Jupyter notebook failed with `RuntimeError: asyncio.run() cannot be called from a running event loop` because Jupyter already runs its own event loop. Maintainer gregorybchris explained the fix: merge the coroutine into Jupyter's loop instead of calling asyncio.run. The pattern is `loop = asyncio.get_event_loop()` followed by `loop.create_task(main())`. The reporter confirmed it worked.
## The verified fix
Jupyter owns the event loop already, so `asyncio.run(main())` will always fail there with this error. Replace it with `loop = asyncio.get_event_loop()` and `loop.create_task(main())` to schedule your coroutine on Jupyter's loop. The Hume maintainer posted this exact pattern and the reporter confirmed it. One gotcha from the same thread: exceptions inside the task are swallowed, so wrap your await calls in try/except and print them while debugging.
