please add application code structure and Procefile info. This error message doesn't really help us understand your problem. - Srikanth Chekuri
please find the files which I tried to create the app at github.com/yegavintin/cab-fare-prediction-practice - yegavintin
actually totally new to this field, was just watching some youtube videos to deploy a built ML model on Heroku through flask but got frequent errors - yegavintin

Not sure why you have web: gunicorn application:app this in Procefile. Your repo doesn't have application module.

Please change you Procfile contents to web: gunicorn app:app.
