Benchmark data download failure

[adhithadias]

I get an error when trying to run the download_reddit_dataset.py file

Traceback (most recent call last):
  File "download_reddit_dataset.py", line 12, in <module>
    assert adj_scipy_csr.has_canonical_format  # the matrix has sorted indices and no duplicates
AssertionError

Any help to solve this is appreciated.
