Gunicorn error with running python eve server - python-3.6

I'm running an API written in python and deployed in Eve server. Further, I'm trying to run with gunicorn(production). The command I have run is gunicorn wsgi:app --preload -w 4 -b 0.0.0.0:7000 and it works as expected. Further, when we run this command we have to hit Ctrl+s for the workers to start running the same code. A question has already been asked with workers waiting indefinitely to start running using the preload option. However, I wanted to remove the preload option. So, when I run gunicorn wsgi:app -w 4 -b 0.0.0.0:7000, I get an error.
Use a production WSGI server instead.

Moreover, when I remove the `-w', the server launches as expected with a single worker.
So, how do I fix this error with workers?
