Hello @qi.han.1,

Thank you for posting. Could you share more information on what licenses you have and more detailed steps on how you reached this error? Did you make any changes to the .py files? How is your path configured on this machine? It seems like it is failing when the optimization is called, but I have not seen that traceback before. Nor have I been able to replicate it so I would need more information to debug.

Regards,
