   Sorry it's hard to provide to tell whether it's more of a modeling issue or 
a bug with mxnet itself without a reproducible error. 
   
   What version of Mxnet do you use? There has been bug with the initializer 
for a short-period of time around Oct-Nov 17. If you can train a toy model like 
MNIST, then it's not an initializer issue. 
   
   If you want to perform 2 classes classification, I'd recommend to start from 
a pre-trained model like in the cat-dog fine tune link above rather than from a 
vanilla model.
