How to Learn Machine Learning
There's a good (but a bit dated) course by Andrew Ng. Also check out tutorials on Keras/Tensorflow. Understanding the mechanics of ML is important to avoid some of the pitfalls, but really you could get going fairly quickly with a few lines of python. So my advice would be to learn a bit about how ML works (it's mostly optimization) and learn a lot about the Dos and Donts. Just a disclaimer: I'm a beginner myself but these are the conclusions I've reached given that I probably won't reach a level where I can tinker too much with ML mechanics. Hope that helps.
