Fail to reproduce result of ResNet18 on ImageNet

Hi I tried the provided script in examples to train ImageNet but only got ~67.5% accuracy, which is far away from the expected result 69.76%. Can anyone give more suggestions? I add color augmentation in training step (transforms.ColorJitter(brightness=0.5, contrast=0.5, saturation=0.5, hue=0.5)) and other settings are identical to provided script.
