There are multiple versions of Python available on our HPCs. On the one hand there are Python modules for Python 3 and 2. Which already has a longer list of additional packages installed, including pip3 respectively pip. On the other hand there is Anaconda installed, which brings an even longer list of packages with it.

For Anaconda see Anaconda page

Additional Packages

There are additional modules which build on top of Python and provide additional Python packages. E.g. the SciPy-bundle provides:

  • numpy
  • scipy
  • mpi4py
  • numexpr
  • Bottleneck
  • pandas
  • mpmath and
  • deap

Another provided Python package is TensorFlow.

If you need additional packages we suggest to install them using either pip for Python2 and pip3 for Python3. You can install into your private HOME using the (pip or pip3) install --user option or share the packages with your colleges using the Workspace module, e.g. for installing a package matplotlib:

## load Python first, this can also be `module load Anaconda3`
module load Python
## maybe you need to specify the Workspace name first OR use `Workspace_Home`
module load Workspace  
## pip install in the Workspace or HOME location
##   the variable PYTHONPACKAGEPATH is set in the Workspace module
pip install --prefix $PYTHONPACKAGEPATH matplotlib

Python module need to be loaded before loading Workspace, because some settings require the Python version information.

Therewith the Python packages are automatically available when

module load Python     ## OR module load Anaconda3
module load Workspace  ## maybe you need to specify the Workspace name first
python -c "import matplotlib"
since $PYTHONPATH and $PATH are set to the above specified location.


if you get the error: ERROR: You must give at least one requirement to install (see "pip help install") you need to reload the Workspace module to properly set the variables. The Workspace module need to have Anaconda3/Python loaded first to read the proper Python Version. module load Python ## OR module load Anaconda3
