Hello, Thank you very much. miniconda worked. I had to manually remove everything from my account and install from scratch, but i got it to work (for testing at least). The only skip I got was:
kwant.solvers.tests.test_sparse.test_umfpack_del ... SKIP which i wont bother to check for now. Please expect more questions as i dig into kwant more. Thanks again.
