We demonstrate a discrepancy in coreml model predictions in iOS11 and iOS12.
Coreml model gives incorrect predictions on iOS12 (while working correctly in iOS11).
We have an identity model that recieves 416x416x3 picture as input and returns the same picture.
This square model works correctly in both iOS11 and iOS12.
We create a model with 740x416x3 input and initialize it with the square model weights.
This rectangle model returns incorrect output in iOS12 (but works correctly in iOS11).
We've tried tuning image scale and coreml convertation scale but it didn't help.
We use
- Python2.7
- coremltools==2.0
- keras==2.1.3
