Description

Jupyter does not use asyncio's default Proactor event loop, and setting it with asyncio.set_event_loop_policy(asyncio.WindowsProactorEventLoopPolicy()) or asyncio.set_event_loop(asyncio.ProactorEventLoop()) has no effect. Everything works as expected on IPython on the terminal, however

Reproduce

  1. Create a fresh virtualenv, install jupyterlab
  2. Run jupyter-lab
  3. Try to execute this example from the Python docs, changing the asyncio.run(get_date()) to await get_date()
  4. A NotImplementedError is raised, because the event loop being used, WindowsSelectorEventLoop, does not support subprocesses

Expected behavior

get_date() result should show up, not an unimplemented error

Context

  • Operating System and version: Windows 10
  • Browser and version: Firefox 99.0.1
  • JupyterLab version: 3.4.0

Everything works as expected on IPython on the terminal, however

I'm running into this issue even with IPython on the terminal, so I'd love to know how you made that work.

@tonnydourado @dan-blanchard I think that your issue is with ipykernel, rather than with JupyterLab. ipykernel 6.28.0 released 3 weeks ago includes ipython/ipykernel#1184 which enabled ProactorEventLoop on Windows. Does upgrading ipykernel fix the issue for you?

Closing this because it seems to be an ipykernel issue that was recently resolved.
