Thanks for your Pull Request!

But I do have a few tips—— Can you rewrite it into the following format?

Now your code style:

else:
            mode = 'test'
            dataset = datasets.Cifar100(mode=mode, transform=get_val_transforms(config))

But there is a better form:

else:
            dataset = datasets.Cifar100(mode='test', transform=get_val_transforms(config))

Thank you again.
