Before you continue
===================

You will need python version 3.7 or later, a version of git that is not ancient (everything newer than 2.10 should be good), and up-to-date pip (``pip install -U pip``) to install the `ESM-Tools`. That means that on the supported machines, you could for example use the following settings:

..
    ollie.awi.de::

        $ module load git
        $ module load python3

.. note::
   Note that some machines might raise an error ``conflict netcdf_c`` when loading ``anaconda3``. In that case you will need to swap ``netcdf_c`` with ``anaconda3``::

    $ module unload netcdf_c
    $ module load anaconda3
