Python is an interpreted high-level programming language for general-purpose programming. Python has had many versions over the years. Most python programs run on Python 2 (example - 2.7.x) or Python 3 (example - 3.5.x).
Modules and Versions
To check the available Python modules on a cluster. Please type the following command.
[NetID@cluster NetID]$ module spider Python
This will show many version of python complied with different toolchains. The first part of the module name (Ex - Python/3.5.1) refers to the python language version. The second part of the module name (Ex - -intel-2016a) refers to the HPRC toolchain used to compile the module.
Python/3.5.1-intel-2016a Python/3.5.2-foss-2017A Python/3.5.2-GCCcore-6.3.0-bare Python/3.5.2-intel-2016a Python/3.5.2-intel-2016b Python/3.5.2-intel-2017A Python/3.5.2-iomkl-2017A
What is a toolchain?
A toolchain on a TAMU HPRC cluster is a collection of tools used for building software. They typically include:
- a compiler collection providing basic language support (C/Fortran/C++)
- a MPI implementation for multi-node communication
- a set of linear algebra libraries (FFTW/BLAS/LAPACK) for accelerated math
For more information on toolchains checkout our Toolchains page.
Which Python to use ?
If your project requires a specific version of python language (Ex. 2.7.11) with specific compiler than use that particular version. We recommend using the most recent toolchain (intel-2017A) with your python version. Once you decide your version than please continue to do your work on the same version. Changing versions everytime can cause errors. In short, current recommended version for python 2 language
Current recommended version for python 3 language
You can use module load command for loading a particular python version on cluster.
