Converting to Core ML format

The easiest way to use pre-trained CNN on iOS is by converting it to the Core ML format:

from keras.models import load_model
model = load_model('Emotions.h5')
coreml_model = convert(model, 
                       image_input_names = 'image', 
                       class_labels = emotion_labels)
...
coreml_model.save('Emotions.mlmodel')
