That's because GetT is not an attribute of the module imagemangager, but of
the class imagemanager.CImageManager.
Try func = Py_GetAttrString(PyDict_GetItemString(mdict,"CImageManager"),
"GetT")
of course, I don't think that's what you want in this case. you'll need an
object to call the function through. Why bother with the class? Just make
sure CImageManager::GetT is a static member or a free function, and "def" it
directly on the module_builder.

You seem to have lots of problems with your approach, but the first one is
the same mistake that you made above: you're trying to access stdout and
stderr through the imagemanager module whereas they're really defined to the
extension class imagemanager.CImageManager
HTH,
