Adjust the lines which correspond to the variables <tt>cplexversion</tt> and <tt>studio_root</tt> so that they have the correct values for your situation, i.e. the version you downloaded and the path you specified when extracting the archive. | |||

Pour installer les libraries de CPLEX tel que <tt>docplex</tt>, nous vous suggérons de le faire à partir d'un [[Python/fr#Cr.C3.A9er_et_utiliser_un_environnement_virtuel | environnement virtuel]]. | |||
Une fois l'environnement virtuel activé, vous pouvez faire l'installation de la librairie avec la commande: | |||
{{Commande|prompt=(ENV) [nom@serveur ~]|pip install docplex}} | |||
L'installation des librairies CPLEX doivent se faire sur le noeud de tête, puisqu'elles ne sont pas disponibles sur CVMFS. | |||
