Failure to import pyOptSparseDriver

问题

I have installed OpenMDAO ver. 1.7.4 & successfully run several tutorial examples. However when issuing the command "from openmdao.api import pyOptSparseDriver" I get the response "ImportError: cannot import name pyOptSparseDriver".

I feel sure that I should be able to import pyOptSparseDriver (& that I have spelled it correctly). I have tried reinstalling OpenMDAO and this seemed to complete without error, but the problem persists.

Could anyone point me in the right direction?

Thanks!

Have you installed pyoptsparse itself? That driver is only available after you install the necessary library.
