title: How to load grayscale image dataset to Mobile net model
body: <p>I am trying to load a grayscale image dataset(fashion-mnist) to MobileNet model to predict hand written numbers but according to <a href="https://colab.research.google.com/github/tensorflow/examples/blob/master/courses/udacity_intro_to_tensorflow_for_deep_learning/l06c01_tensorflow_hub_and_transfer_learning.ipynb#scrollTo=s4YuF5HvpM1W" rel="nofollow noreferrer">this</a> tutorial only RGB images can be loaded to the model. When I try to feed fashion-mnist samples, it gives me the following error</p>
  
  <blockquote>
    <p>Error when checking input: expected keras_layer_13_input to have shape
    (224, 224, 3) but got array with shape (224, 224, 1)</p>
  </blockquote>
  
  <p>How to solve this problem ?</p>
