Question about why repeat(2) is needed?

[chenyuqi990215]

I'm reading the code in https://github.com/tmbdev-archive/webdataset-examples/blob/master/main-wds.py, I'm confused about in Line 332, you write train_loader.repeat(2).slice(number_of_batches). However, it seems that the data will be reversed twice if a repeat operation is used. I'm wondering why we need the repeat(2) here?
