   > @anirudhacharya I'm not sure if relu grad should act like that. As a sanity check, consider if nan is larger than or smaller than 0.
   
   nan compared to any number is always `False`. `nan > 0` -> `False` and `nan < 0` -> `False`
   
   Ref - https://stackoverflow.com/questions/49011370/nan-propagation-and-ieee-754-standard/49040225
   
   But there are languages and libraries which consider nan to be greater than any number even np.inf.
