Python/Pyomo entro JModelica

Question

Ho installato un pacchetto di risolutore commerciale (OCT) per JModelica (python-based) -> Quando voglio aprire JModelica tramite "ipython" ottengo il seguente messaggio di errore:

Traceback (most recent call last): 

    File "C:\OCT-1.0b1\Python27\scripts\ipython-script.py", line 5, in <module> 

    from pkg_resources import load_entry_point 

    File "C:\OCT-1.0b1\Python27\lib\site-packages\pkg_resources.py", line 2825, in 

<module> 

    add_activation_listener(lambda dist: dist.activate())

    File "C:\OCT-1.0b1\Python27\lib\site-packages\pkg_resources.py", line 1836, in 

declare_namespace 

    path = sys.modules[parent].__path__ 

KeyError: 'pyomo' 

io lavoro con pyomo tramite spyder/Anaconda2 (64-bit)

sarebbe grande, se qualcuno mi potrebbe aiutare!

È possibile installare pyomo in virtualenv ed evitare conflitti con JModelica:
