== Phoenix ==
The default version of Python on the Phoenix cluster is 2.3.4, the version which comes with Red Hat 4.5. We also have versions 2.6 and 3.0 installed in /soft/python/bin. To use them, you'll need to either fully specify the path to the version you want to use, or load the appropriate module. The modules alias python to the module version and set LD_LIBRARY_PATH, which helps to eliminate some errors that you may otherwise encounter when you use Python modules.
$ /soft/python/bin/python2.6
$ /soft/python/bin/python3.0
or
module load python/2.6
module load python/3.0
For example,
$ module load python/2.6
$ python
== Python modules ==
We add Python modules (i.e., libraries) as users request them. The non-default site packages are in /soft/python/lib/python<version>/site-packages.
If you encounter any problems with a Python library module, try loading the Python environment module (as above).
