DeprecationWarning: There is no current event loop

[greghesp]

I'm not a too knowledgeable with python at the moment, however I noticed that when running the request example, the following error is returned

DeprecationWarning: There is no current event loop
  loop = asyncio.get_event_loop()
Exception in callback _ProactorDatagramTransport._loop_reading()
handle: <Handle _ProactorDatagramTransport._loop_reading()>
Traceback (most recent call last):

    ov.WSARecvFrom(conn.fileno(), nbytes, flags)
OSError: [WinError 10022] An invalid argument was supplied

The above exception was the direct cause of the following exception:

Hi there,

The latest version, v1.2 fixes many issues concerning Windows. You can try the new CLI to verify that it's working on your system. The new documentation should also help you to implement a working solution.

Cheers! Joe
