You don’t need root privileges to install packages in your home directory. You can do that with a command such as
pip install --user numpy
or from source
python setup.py install --user
See https://stackoverflow.com/a/7143496/284795
The first alternative is much more convenient, so if the server doesn’t have pip
or easy_install
, you should politely ask the admins to add it, explaining the benefit to them (they won’t be bothered anymore by requests for individual packages).
