title: Getting loss as "nan" while running CNN (using Keras)
body: Need Suggestion
  
  <p>I am trying to design a model to guess Facial-Points. Its a part of Kaggle Competition (<a href="https://www.kaggle.com/c/facial-keypoints-detection" rel="nofollow noreferrer">https://www.kaggle.com/c/facial-keypoints-detection</a>).</p>
  
  <p>In this solution, I am trying to design a CNN model (using Keras Library), as a Multi-variable regression model to Predict the co-ordinates of Facial-points.
  Issue Faced --> I am getting loss as "nan"</p>
  
  <p>Solutions tried --
  1. Tried optimizers - Adam, SGD
  2. tested with Learning rate 0.01 to 0.00001
  3. Tried with various batch sizes</p>
  
  <p>Can anyone suggest, if I am missing something. The code is present in below link -
