Do we have validation dataset for cifar, imagenet datasets?

So I have a stupid question, I apologize in advance!

I am following the steps here: and they are all clear.
In training a classifier I defined the trainset and testset as explained in the tutorial.
Here is my question, why we dont have the validationset defined?

Can anyone please tell me how I can do that :sunglasses: thanks

Here is a nice gist created by @kevinzakka with CIFAR10.
