What is the use of np.expand_dims() and preprocess_input()?
Hey @HemantKumar, we need to pass image array as (1,224,224,3) and not as (224,224,3) and hence we need to expand one dimension, so we used np.expand_dims.
We have used preprocess_input() to apply same preprocessing that was applied before the actual model was trained. It may be the case that image array was / 255.0 or not. So preprocess function applies the same preprocessing that was applied for training actual resnet etc model.
