How do I build scipy with umfpack to silence this error:
Exception AttributeError: "'UmfpackContext' object has no attribute '_symbolic'" in <bound method UmfpackContext.__del__ of <scipy.sparse.linalg.dsolve.umfpack.umfpack.UmfpackContext object at 0x101b62050>> ignored
and speed up random_walker? I've just been doing a pip install scipy till now.
