Was it a typo on the Website or why is the 2017 10.5 inch iPad Pro (A10X + 4GB of ram) not supported? Because the 7th generation iPad which has an A10 processor + 3GB of ram is supported! It’s weird because the A10X is a more powerful processor so why does it not make the cut?

I want to make a feature in my App, where a user can use the Camera to capture the data of an LCD screen, for example a thermostat or a digital clock. I downloaded the sample Text recognition project and tweaked it to only search for numbers. But whenever I show it a photo of a digital number (LCD/LED) it just cannot recognize it. So I searched for an answer, and I came to the conclusion that I have to train a model with these kind of numbers. My question is, how should I do it, what kind of photos should I take for training? Thank you for the help in advance! Have a nice WWDC
