You can of course install other versions of Python in your home. A very comfortable way of doing that is by using [[https://github.com/yyuu/pyenv|pyenv]]. You will find a howto on that website with detailled instructions how to use it. You can of course install other versions of Python in your home. A very comfortable way of doing that is by using {{{pyenv}}}. Here is a short install howto. Further down you find links to documentation etc.

With pyenv you can also install additional Python modules like the whole scipy stack in the home directory.  * Install pyenv:
  {{{
curl -L https://raw.githubusercontent.com/yyuu/pyenv-installer/master/bin/pyenv-installer | bash}}}

* Add the following three lines to your ~/.bashrc:
---snip---
export PATH="$HOME/.pyenv/bin:$PATH"
eval "$(pyenv init -)"
eval "$(pyenv virtualenv-init -)"
---snap---

* Restart your shell so the path changes take effect:
exec $SHELL


Install some python versions:
pyenv install 2.7.7
pyenv rehash

Make sure that this new python version will be used when you run python.
You only need to run this command once:
pyenv global 2.7.7

pyenv: 5 MB
python 2.7.7: 110 MB

Update:
pyenv update

Python

We provide as many modules as possible that come with the current Debian GNU/Linux stable release. Nevertheless, that might not be enough for your needs since you may want to use the newest version of some module or one that is not part of Debian.

Since Python 2.6 there is an easy way to install missing or outdated modules in your home through easy_install.

How to use easy_install

Modules will be installed in your home within ~/.local/. You do not need to adapt the PYTHONPATH environment variable since python will look for modules in this directory automatically.

Installing other versions of Python

You can of course install other versions of Python in your home. A very comfortable way of doing that is by using pyenv. Here is a short install howto. Further down you find links to documentation etc.

  • Install pyenv:
    • curl -L https://raw.githubusercontent.com/yyuu/pyenv-installer/master/bin/pyenv-installer | bash

* Add the following three lines to your ~/.bashrc: ---snip--- export PATH="$HOME/.pyenv/bin:$PATH" eval "$(pyenv init -)" eval "$(pyenv virtualenv-init -)" ---snap---

* Restart your shell so the path changes take effect: exec $SHELL

Install some python versions: pyenv install 2.7.7 pyenv rehash

Make sure that this new python version will be used when you run python. You only need to run this command once: pyenv global 2.7.7

pyenv: 5 MB python 2.7.7: 110 MB

Update: pyenv update

Installation of custom (non easy_install-able) Python modules in the home directory of a user

We are sometimes asked for newer version of Python modules. We do no longer build Python modules in SEPP as the requests for modules and their versions is too widespread to keep these modules maintainable.

On this page we will list some bash-snippets that install some often requested modules in a users home.
