Keras fit_generator and fit results are different

Question

I am training a Convolutional Neural Network using face images dataset. The dataset has 10,000 images of dimensions 700 x 700. My model has 12 layers. I am using a generator

Answer 1

You have to make sure that your data generator shuffles the data between epochs. I would suggest you create a list of possible indices outside of your loop, randomize it with random.shuffle and then iterate over that inside your loop.
