Hi!
I'm trying to run chat demo with python main.py command, and getting this is my traceback :

Traceback (most recent call last):
  File "main.py", line 40, in <module>
    main()
  File "main.py", line 36, in main
    web.run_app(app)

    loop.run_until_complete(runner.setup())

    self._app._set_loop(loop)
AttributeError: 'coroutine' object has no attribute '_set_loop'
sys:1: RuntimeWarning: coroutine 'init_app' was never awaited

Hi @smart-developerr
I wasn't able to reproduce your error with python 3.6.
aiohttp version I got after pip install -e . is 3.6.2 (since it is not pinned in requirements)

Reproducible with aiohttp==3.0. I also encounter different problems with aiohttp 3.1-3.5. Have bumped the setup.py file to require atleast 3.6.
