I solved the problem thanks to @AkshayKumar007 answer on github. That was the most convenient solution for me.

Hey guys, I was also facing the same problem. So to summarize, if you're using socket-io, don't do flask run. First, add

    socketio.run(app)

At the end of your application. To run it just do

python3 __init__.py
