nodes in the Maxwell cluster run under Centos 7. The python installations provided by Centos (and EPEL) repositories are mainly
- python 2.7
- python 3.6
Both versions are still maintained but actually have reached end of life quite a while ago. If you don't have to use these version don't use them. The only advantage of these python versions is the availability on all major platforms running Centos 7. A python virtual environment will usually work likewise on maxwell and on bird/naf.
Both python versions are installed in /usr/bin and are directly accessible without any modules:
python --version # likewise for python2 and python2.7 Python 2.7.5 python3 --version # likewise for python3.6 Python 3.6.8
The python packages installed for these versions are outdated, and will largely not be updated anymore. For a list of available packages and version please visit Python modules on Maxwell.
