Try to run this using Python 3.6. I didn't test it on python 3.7.

This looks to me like the C++ library wasn't installed correctly because it's failing when gettin the function pointer. Make sure you compile it (bin/createGraphLibFile.sh) and then install. I verified that this does work with python 3.7 and macOS using the Home-brew python.
