Package: python-numpy
Version: 1:1.8.2-2
Severity: grave
Justification: renders package unusable
Dear Maintainer,
importing numpy fails with an ImportError exception. The following
backtrace is produced:
>>> import numpy

This is with Python 2.7.8, but I get the same error with Python 3.4.2. I've
also tried installing python-numpy 1:1.9.0~rc1-1 from experimental, which
results in the same error when importing.
This may very well be a bug in libblas3, but I have installed the most
recent
version of libblas3 and the error manifests when importing numpy. I'll
gladly
report a bug for libblas3, if you think the problem has to be solved there.

This is the cause of your problem, some locally installed incompatible
lib. Closing.
