Non Reproducible result with GPU

I tried that workaround in the simple case of the cifar10 tutorial:
http://pytorch.org/tutorials/beginner/blitz/cifar10_tutorial.html
after having added only the Flip transform line:
transforms.RandomHorizontalFlip(),
I also inserted a seed initialization:
torch.manual_seed(0)
and I even disabled the shuffle.
I am still not able to reproduce the results. Any other idea?
