A Future or coroutine is required - asyncio

I'm trying to asynchronously load content of a web page. I have used requests_html, as I face some problem installing it on my server so I am using asyncio

@asyncio.coroutine
async def extract_feature():
    try:
        count = 0
        key = ''
        loop = asyncio.get_event_loop()
        response = await loop.run_in_executor(None, requests.get, link)
        soup = BeautifulSoup(response, "html.parser")
        return soup
loop = asyncio.get_event_loop()
result = loop.run_until_complete(extract_feature)

But this raises A Future or coroutine is required.

One thing to mentioned I'm using Python 3.5.0 (v3.5.0:374f501f4567) which doesn't support run.

You need to call extract_feature before passing it to run_until_complete, i.e.:

result = loop.run_until_complete(extract_feature())

Also, the asyncio.coroutine decorator shouldn't be used with functions already defined as async def - just omit it.
