In this tutorial, you will learn how to perform automatic age detection/prediction using OpenCV, Deep Learning, and Python. By the end of this tutorial, you will be able to automatically predict age in static image files and real-time video streams with reasonably high accuracy.

Don’t override __hash__ and __eq__ to force objects to hashable. Use immutable objects instead.

As your project grows, it might get to the point that it becomes too hard to handle with just single VM or some simple SaaS solution. You can solve that by switching to more robust solution like Kubernetes. That might however, be little too complex if you are not familiar with it's concepts or if just never used it before. So, to help you out - in this article - we will go over all you need to get yourself started and have your Python project deployed on cluster - including cluster setup, all the Kubernetes manifests and some extra automation to make your life easier down the road!

Using VPNs and/or other tunnelling techniques can go a long way to keeping crawlers under the radar and collecting data as productively as possible.
