I'm using the default test input files.
I've attached pdb screenshot during the run.
Environment: Ubuntu 18.04 Anaconda (Python 3.7.3),
torch-geometric==1.3.0 torch-scatter==1.3.0 torch-sparse==0.4.0 torch-spline-conv==1.1.0 metis==0.2a.4

I got the same problem.

The problem is the python version. I don't think the symbols provided to support the metis library are available in python 3.6 and above, so it is better to test this out in python 3.5. Simply create a conda environment with python 3.5 and it will work well enough.
