   @sandeep-krishnamurthy Thanks for asking, a previous quick going through 
this issue, seems the difference caused by different computation method on 
CPU/GPU backend, it's iters by iters v.s. accumulation. I also tried the 
ResNet50 training on CIFAR, the training and validation accuracy are all okay 
on CPU.
