I gave a tutorial to the SharpestMinds community this week on Flask and Heroku that proved useful. So I edited it and uploaded it.
I essentially live code a basic web app from scratch to host an image classifier. It is scrappy and cuts a few corners, but the result is a working MVP.
I think this should be helpful for folks familiar with machine learning but want an intro to web development. Hoping this will be the first in series of tutorials on productionizing machine learning code.
