What are the content in exp/datasets/celeba and exp/datasets/ood_celeba?

[LinWeiJeff]

Hello, I appreciate you provided this inspiring paper and excellent code.
I want to implement sampling according to the instruction you provided in this github repository.
However, I wonder what the difference between "exp/datasets/celeba" and "exp/datasets/ood_celeba" is? I mean, what is "out of distribution CelebA images"?
And I wonder if I should put something into these two folders (exp/datasets/celeba and exp/datasets/ood_celeba)? for example, putting celeba images in "exp/datasets/celeba" folder? or just keep these two folders empty?
Please reply me, thanks a lot!
