-First enable the module package to search also private module directories
+Please read [[easybuild_environment|here]].
-<code bash>
-module load use.own

-the line above will create a $HOME/privatemodules if it does not exist and its path will be searched for the presence of environment modules files.
-Let us  now install some packages to an arbitrary location and upgrade (__only in $PYTHONUSERBASE__) an already system-wide installed package
-<code bash>
-export PYTHONUSERBASE=/somewhere/I/can/write/to
-pip install --user SomePackage
-pip install -I --user SomePackageThatWASInstalledSystemwide
-</code>
-Create a file, say `$HOME/privatemodules/super-module' with the following contents
-<code bash>
-#%Module 1.0
-#
-#
-#
-prepend-path  PATH          /somewhere/I/can/write/to/bin # if executables were installed
-prepend-path  PYTHONPATH    /somewhere/I/can/write/to/lib/python2.7/site-packages
-</code>
-and type
-<code bash>
-module load super-module
-</code>
-and you are ready to use your newly created python environment. Note that is similar procedure can be repeated using python3.
 ===== Example: numpy with openBLAS =====
 In this example we create a python2 virtual environment in which we will install the latest version of numpy that will use the openBLAS library.
