want to know where data is augmented in code?

[iPwnXX]

I looked through the code and was trying to find out how data augmentation defined in util.py works, and I found that the raw feteched data go through each augment funcs in iteration in preprocess() in datasets.py, which is only invoked in get_example(), but I didn't find blocks or functions that invoke get_example().
so how did data augmentation happens in running?
thanks for any help.
