STL10 does not download

[wittenator]

🐛 Bug

I am currently working on the STL10 dataset, but it seems that there is some problem downloading the data. It gets stuck while downloading judging from the stack trace. I hunted down the URL from the dataset (http://ai.stanford.edu/~acoates/stl10/stl10_binary.tar.gz) and there does not seem to be a problem from their side. Does somebody else have the same problem?

To Reproduce

Steps to reproduce the behaviour:

1. Import torchvision
2. Instantiate a STL10 Dataset

import torchvision

torchvision.datasets.STL10(root="datasets", split='unlabeled', folds=None, download=True)

Expected behaviour

The dataset should be downloaded and extracted.
