Hey guys, here is my second blog post: Second fast.ai Project.
In it, I walk you through how I made my model and deployed it with Flask and Heroku.
Here is the deployed model: https://ptear-blog.herokuapp.com/sports-players (may take a while to load)
To use it, simply upload an image of either a soccer player, a rugby player, or a water polo player.
Happy to try to answer any questions.
