Python Tika error: URLError: <urlopen error unknown url type: c>

[danielepiu]

Hi, I've been using a lot python tika to exctract text from some pdfs. Suddenly Tika doesn't work any more with the following code and similar:

from tika import parser
document = parser.from_file("prova.pdf")['content']

and every time I get this error:

I tried to unistall tika python, tika server, java, python... basically everything. And the strange thing is that suddenly I have the same issue in my second pc. Any suggestions ? Thanks a lot.

Hmm likely a network issue and also one with the underlying request library or its connection to the URL (and more than likely since it's not in requests since that library is so well tested, maybe a network or proxy error for that URL on your home network?) Either way the issue isn't in Tika.
