OpenCV - where to start?

Question

Python

Hello everyone)
I decided to start my journey in machine learning, namely in the topic of pattern recognition. I have been writing in python for a long time. Mostly worked with web projects. The look fell on the opencv library. Where should you start? Maybe take another library in order to more smoothly merge into the field of machine learning for pattern recognition? Or is it stupid according to the OpenCV manual?
