   @terrychenism  I trained the resnext model according to the training log you 
shared.  You first use 480 shorter side of image to train the model which can 
add more training data compared to 256, after 100 epochs, you use the 256 
shorter side to  improve accuracy.  The top-1 of resnext-50 is 76.8%. But the 
top-1 of resnext-50 is 77.8% in Resnext paper implemented in Torch and the 
paper says they just use shorter side 256.  Can Mxnet has performance as good 
as  Torch?
