Deploying a Deep Learning Image Classification Model with NodeJS, Python, and Fastai

TL|DR: Use this to easily deploy a FastAI Python model using NodeJS.

You've processed your data and trained your model and now it's time to move it to the cloud.

If you've used a Python-based framework like fastai to build your model, there are several excellent solutions for deployment like Django or Starlette. But many web devs prefer to work in NodeJS, especially if your model is only part of a broader application.

My friend Navjot pointed out that NodeJS and Python could run together if we could send remote procedure calls from NodeJS to Python.

Everything You Need to Know About Body Language

The most honest part of the human body are the feet. Why?

Because we've practiced lying with our words and faces since pre-school.

In this summary, we'll cover the top signals and signs explained by FBI body language expert Joe Navarro in his best-seller What Every Body is Saying.
