Import problems with cython: " module 'gtsam' has no attribute 'NonlinearFactorGraph' "

[Niklas Stannartz]

Hello,

I hope there is an easy answer to my problem. I installed the cython wrapper as described in the cython readme.

When I include the installation directory (usr/local/cython) I receive the error "No module named 'gtsam_unstable' " when trying to import gtsam.

When I include the build directory as suggested in Issue356 the import works but when trying to assign the graph I receive the error " module 'gtsam' has no attribute 'NonlinearFactorGraph' "

Thanks in advance.
