Free Web Deployment?

Hi guys!

I am trying to get the ‘teddy bear detector’ (https://github.com/render-examples/fastai-v3) to work on Heroku, but there is still some problem I do not have a clue about.

There is the following error message in the log:

2020-05-14T20:47:41.918666+00:00 heroku[router]: at=error code=H14 desc=“No web processes running” method=GET path="/favicon.ico" host=cnn-test.herokuapp.com request_id=b46094fa-f238-4fa1-835d-f0d0b8a9e3b7 fwd=“37.146.80.70” dyno= connect= service= status=503 bytes= protocol=https

I am thinking of putting this demo app to work locally on my Mac, but I am not sure how to do that.
Could you please give me any direction of how it can be done?

Thank you very much!

Tony
