combine_A_and_B issue

[jho925]

When I run the file, it outputs

[fold_A] = ./path/A/
[fold_B] = /path/B/
[fold_AB] = ./path/AB
[num_imgs] = 1000000
[use_AB] = False
[no_multiprocessing] = True
split = test, use 189/189 images
split = test, number of images = 189
split = train, use 756/756 images
split = train, number of images = 756

But when I check the folder, no images have been created?
