Just get a low accuracy of 75.8 with resnet50 on ImageNet

[mountain111]

I train resnet50 on ImageNet with GPUs=8, batchsize=256, learning-rate=0.1, epochs=90, and momentum=0.90.
The attained top1 accuracy is 75.80, lower than the reported 76.15. The gap is not marginal on the large-scale ImageNet.
Why does the difference exist?

I get 75.644 with resnet50 on ImageNet，I think this might be normal？
