I noticed the the LeastSampledClassSampler was a bit slow, when looking at the code I saw that the sample function has

for class_, indicator in enumerate(self.labels[self.indices[chosen_index]]):
            if indicator == 1:
                self.counts[class_] += 1

in it. I suppose it would be faster if this was not a python for loop but the following:

self.counts += (self.labels[self.indices[chosen_index]] == 1).int()

I'm pretty new to github so not sure how I would have turned this into a pullrequest.
