Which samples of data is used in a batch when shuffle=True?

2

Indexing over DataLoader suggests to use DataLoaderIter.sample_iter but it is not clear to me how.

I have used the following as suggested in Indexing over DataLoader.

DataLoaderIter = iter(trainloader)
for i in enumerate(DataLoaderIter.sample_iter) :
print i

But, interestingly this does not return the indices of the first two batches. Do you how can I fix this?

Thanks.
