It's really easy to use, it works great with my existing code base and has all kinds of neat features. I'd say that maybe there are some more tutorials out there showing how to get started but other than that, nothing. If you're looking at machine learning, this should be your first stop! You can do anything from basic image recognition to advanced deep neural networks in no time flat.
Also, the community support around TF is fantastic. They have weekly meetups where people go over problemsโฆ
