+# Installing a missing Python package #
+
+To install a missing python package you may need, you must install it from its sources. In this example we try to install a package we call 'super_package'
+As IRENE has no http connexion to the internet, you must download it on you mesocentre account : 
+On ciclad :
+{{{
+> wget <address of the source>.tar.gz
+}}}
+ 
+Then you must scp it to IRENE, on your WORKDIR. For this, log in to irene and : 
+{{{
+> scp login@ciclad.address.fr:/path/to/your/archive $CCCWORKDIR/dossier_de_sources/super_package.tar.gz
+}}}
+From now on everything will be done on IRENE.
+Uncompress the archive : 
+{{{
+> tar -xvzf  $CCCWORKDIR/dossier_de_sources/super_package.tar.gz
+}}}
+We want to install the package for a usage with python3.7, thus, we load the module and add our source folder to the PYTHONPATH :
+{{{
+> module load python3/3.7.5
+> export PYTHONPATH="${PYTHONPATH}:$CCCWORKDIR/dossier_de_sources/lib/python3.7/site-packages"
+# You may need to do some mkdir to create lib/python3.7/site-packages
+}}}
+Now we install the package :
+{{{
+> cd super_package
+> python3 setup.py install --prefix=$CCCWORKDIR/dossier_de_sources
+}}}
+
+
+The package is now installed. 
+
+To use it on a next session, we will have to load the module and update the PYTHONPATH :
+{{{
+> module load python3/3.7.5
+> export PYTHONPATH="${PYTHONPATH}:$CCCWORKDIR/dossier_de_sources/lib/python3.7/site-packages"
+}}}
+
+You can now import this package on your python scripts.
