If you need additional modules, we encourage you to installing them in your own filespace using one of the methods described below:

How to install own modules for Python 3 or Python 2.7

You can use the pip utility for easy installation. See the following page for details (do not forget the --user option), like so:

 $ pip install --user package-name

You can use easy_install, too.

How to install own modules for any version of Python

See the Python documentation for details:

  • Configure Python to find the new modules by adding the following line into your ~/.bashrc (replace python2.X with python2.6 or python2.7 depending on the version of python you are using):
$ export PYTHONPATH=$HOME/lib/python2.X/site-packages/:$PYTHONPATH

Then you can re-source your ~/.bashrc to get the changes into the current shell avoiding logging out:

$ source ~/.bashrc
  • Download and unpack the source files. (Here as an example we download the xlrd package.)
$ wget --no-check-certificate https://pypi.python.org/packages/source/x/xlrd/xlrd-0.9.3.tar.gz
$ tar xzf xlrd-0.9.3.tar.gz
$ cd xlrd-0.9.3/
  • Install a module specifying a prefix
$ python setup.py install --prefix=$HOME
  • If a module requires a fortran compiler then we strongly recommend to specify gfortran instead of g77 like so:
$ python setup.py build --fcompiler=gnu95 install --prefix=$HOME
