Hi, I have the same problem. Did you find any solution?

It's a problem with gevent. Coros was deprecated and is now removed.

Downgrade to a previous version with

pip install gevent==1.0

Thanks a lot, it seems to work now, at least for simple articles.

I had an older version of the render server running on Ubuntu 14.04 and it seemed to work better:

- The rendering page updated automatically. Now I have to reload the page manually.

- It seemed to work for more complex pages. Now I very often get the error "WARNING: Article could not be rendered - ouputting plain text.

Potential causes of the problem are: (a) a bug in the pdf-writer software (b) problematic Mediawiki markup (c) table

is too wide"

Okay, I hacked Image.py of Pillow to make tostring available again. Now more pages can be rendered properly.

I wish the render server components would be upgraded as they seem to be quite outdated.

I ran into the same problem. I found out that gevent.coros was renamed to gevent.lock. Therefore you could also update the code of mwlib by doing:

find . -type f -exec sed -i 's/coros/lock/g' {} \;

I also got the error KeyError: 'revisions', and solved it by replacing revs = e["revisions"] with revs = e.get("revisions","") in pp/local/lib/python2.7/site-packages/mwlib/net/sapi.py:311.
