Hey, If you have problem using python 3 in labs, this is the right place.

Running python 3 directly

This one is simple:

python3 pwb.py login

Building a virtual environment

You need to add "-p python3" otherwise it doesn't work

virtualenv -p python3 py3

Then you can use pip directly (pip3 doesn't work). For example:

source ~/py3/bin/activate
pip install pywikibot

will install pywikibot in python 3 environment.

Running scripts in grid engine

In order to run scripts in grid engine you can't use python 3 in current release (yet) you need to use trusty release. For example

jsub -once -N cool_script -l release=trusty python3 /data/project/yourtool/pywikibot/pwb.py login

without "-l release=trusty" it won't work.
