Mein Betriebssystem ist Fenster 7, Pulp Version ist 1.6.1, Gurobi Version ist 7.0.1. Gurobipy kann erfolgreich importiert werden. pulp.solvers.GUROBI hat den Test bestanden, also konnte ich Gurobi benutzen. Pulp.solvers.CPLEX_CMD ist jedoch fehlgeschlagen. Hier ist die Fehlermeldung:Pulp.pulpTestAll() Test fehlgeschlagen, zu viele Werte zum Entpacken

Haben Sie das herausgefunden? Ich bekomme den gleichen Fehler. – SashaZd
@SashaZd, nein, ich ignorierte einfach den Fehler –
Ich deinstalliert und Gurobi neu installiert. Diesmal klappte es :) – SashaZd
