title: CreateML MLModel works on playground UI but not in app
body: <p>I'm working on a machine learning app that classifies numbers that are hand drawn. I have made a model using CreateML that supposedly has 100% accuracy (I will admit my sample size was only about 50 images per number). When running it on my app however, it does not work. To see if it was a problem with my app, I downloaded the <a href="https://developer.apple.com/documentation/vision/classifying_images_with_vision_and_core_ml" rel="nofollow noreferrer">Apple Vision+CoreML Example</a> Xcode project and replaced the MobileNet classifier with my own. I loaded in the images saved on my phone from my own app and the classifications were still inaccurate. What makes this interesting is that I tried testing the exact same images in the CreateML UI space on the playground where you can test images and the classification works.</p>
  
  <p>TL/DR: The image classification works on the CreateML Live View on playgrounds but does not on the exact copy of the vision+coreML example project from Apple.</p>
