title: Problem in training my MNIST model in Keras
body: <p>I have prepared a sequential model using Tensorflow for recognizing digits. But after compiling the model whenever I try to train my model, it shows only 1875 training sample; though when I print its length, it shows me the length of 60000 samples.
  Can't figure out why this occurs?
  Any hint please!</p>
