Hi @dan  To add to what @Laurence_Moroney said, you can also check out the MOOCs mentioned on this page: Basics of machine learning  |  TensorFlow 12 featuring @Laurence_Moroney and @Magnus 
Also, if you haven’t already, check out the notebooks you can run in Colab: Machine Learning Basics with Keras (under TensorFlow.org 7 Tutorials: Basic classification: Classify images of clothing  |  TensorFlow Core 2) and TensorFlow Basics (under TensorFlow.org 7 Guides: Eager execution  |  TensorFlow Core 3) - made by @billy , @markdaoust , @Anirudh_Sriram , and many more from the team.
And, there’s this awesome course: Machine Learning Crash Course  |  Google Developers 6   (You can find more resources at Machine learning education  |  TensorFlow 2).
