Next step is to create proc file
for that open following url and go to gunicorn web server section in that
https://flask-socketio.readthedocs.io/en/latest/
and copy following code from webpage in new file and rename that as Procfile
gunicorn -k geventwebsocket.gunicorn.workers.GeventWebSocketWorker -w 1 module:app
Here module:app is nothing but main app name, in our case app name is app itself
app = Flask(__name__, static_url_path='/static')
& Module is application file name, so in our case its app only
web: gunicorn -k geventwebsocket.gunicorn.workers.GeventWebSocketWorker -w 1 app:app
So, the final content of Profile file is as above
then do pip install gunicorn as below
PS D:\GeorgiaTech\ClassWork\Project3_HerokuAPI> pip install gunicorn

Now, after deploying when I validated it using https://usacity-accidents-population.herokuapp.com/ it gave an error for websocket..
Now, this pip install did not work for me and it failed.. and looks like for same reason after deploying the app, it was giving that websocket error...
So, finally I changed Procfile as follows
web: gunicorn -w 1 app:app
and committed and re-deployed the code and it started working -- https://usacity-accidents-population.herokuapp.com/city
