title: Jupyter Notebook with Python 3.8 - NotImplementedError
body: <p>Upgraded recently to Python 3.8, and installed <code>jupyter</code>. However, when trying to run <code>jupyter notebook</code> getting the following error:</p>
  
  <pre><code>  File "c:\users\user\appdata\local\programs\python\python38\lib\site-packages\tornado\platform\asyncio.py", line 99, in add_handler
      self.asyncio_loop.add_reader(fd, self._handle_events, fd, IOLoop.READ)
    File "c:\users\user\appdata\local\programs\python\python38\lib\asyncio\events.py", line 501, in add_reader
      raise NotImplementedError
  NotImplementedError
  </code></pre>
  
  <p>I know Python 3.8 on windows switched to <code>ProactorEventLoop</code> by default, so I suspect it is related to this.</p>
  
  <p>Jupyter does not support Python 3.8 at the moment? Is there a work around?</p>
