seg fault at test run on CentOS
Hello, I have installed the latest version of kwant on a CentOS system that I do not have root access. So I installed it on my home directory. When I run the test file, i get the following seg fault. python3 -c 'import kwant; kwant.test(verbose=2)' /lib/python3.6/site-packages/kwant-unknown-py3.6-linux-x86_64.egg/kwant/solvers/default.py:18: RuntimeWarning: MUMPS is not available, SciPy built-in solver will be used as a fallback. Performance can be very poor in this case. "Performance can be very poor in this case.", RuntimeWarning) kwant.graph.tests.test_core.test_empty ... ok kwant.graph.tests.test_core.test_num_nodes ... ok .... kwant.tests.test_lattice.test_neighbors ... ok kwant.tests.test_lattice.test_shape ... ok kwant.tests.test_lattice.test_wire ... ok kwant.tests.test_lattice.test_translational_symmetry ... Segmentation fault Where I skipped a lot of lines, they were ok for most, skipped when related to MUMPS. I am not that familiar with python or kwant to know what this error means. Can someone help? Thanks Fatih
