creating a progress bar for a validation test Python

Question

The following code is used to find p-values for a significant test on Cifar-10 database. Because we need a min of 1000 permutations, it is a very slow process, and I want to inlude a progress bar to show how time for each permutation. I was thinking of using the tqdm library and sleep function, but am stuck on where to go from here. any help would be greatly appreciated!
