Hi all,

which UMFPACK versions are supported in scipy ? help (linsolve) lists version 4.4 and version 5.0 of UMFPACK.

Yes. That gives you your answer. If you try another version and it works for you, go ahead and tell us, and we'll update that docstring. If that docstring doesn't get updated, that's because no one has told us that any other version works.

Hi Robert, This is to let you know that I have tried to use UMFPACK version 5.0.1. Here are my findings: scipy.test(1) results in Warning: FAILURE importing tests for <module 'scipy.linsolve.umfpack.umfpack' from '...y/linsolve/umfpack/umfpack.pyc'> /usr/local/lib64/python2.4/site-packages/scipy/linsolve/umfpack/tests/test_umfpack.py:17: AttributeError: 'module' object has no attribute 'umfpack' (in ?)
