Depuis le terminal, lorsque réarrange avec l'option --arrange=lp et le moteur cplex, une erreur python est levée :

mocodo --arrange=lp --engine=cplex --input sandbox.mcd

Le fichier mit en paramètre contient le code sur mocodo web, mon mocodo est en version 2.3.9, mon python en 3.8.5, et cplex est en 20.10

La version 3.0 ne prend plus en charge la résolution par programmation linéaire.
