HTTP Error 301 when running test script

[epelofske]

I am running on Linux Mint. I went through the README to try out the 20 newsgroups experiments.

I am encountering the following error:
File "/usr/lib/python3.6/urllib/request.py", line 650, in http_error_default
raise HTTPError(req.full_url, code, msg, hdrs, fp)
urllib.error.HTTPError: HTTP Error 301: Moved Permanently

The full error output I attached in a text file.
