title: Python Super Resolution Keras issue
body: <p>I'm having an issue i can't manage to solve.
  I'm just approaching the Super Resolution Images on Python and i found this on github: <a href="https://github.com/titu1994/Image-Super-Resolution" rel="nofollow noreferrer">https://github.com/titu1994/Image-Super-Resolution</a>
  I think this is exactly what i need for my project.
  So i just install everything i need to run it and i run it with this:
  python main.py (path)t1.bmp</p>
  
  <p>t1.bmp is an image stored in the "input-images" directory so my command is this:</p>
  
  <p>python main.py C:\Users\cecilia....\t1.bmp</p>
  
  <p>The error i get is this:</p>
