Hi all,
I recently upgraded NumPy from 1.9.1 to 1.10.4 on Python 2.7.8 by using
pip. As always I specified the paths to Blas, Lapack and Atlas in the
respective environment variables. I used the same compiler I used to
compile both Python and the libraries (GCC 4.6.1). The problem is that
it always tries to get Blas symbols in the wrong library:
>>> import numpy
Traceback (most recent call last):
File "<stdin>", line 1, in <module>

from . import multiarray
ImportError:
/usr/local/python2/2.7.8/x86_64/gcc46/New_build/lib/python2.7/site-
packages/numpy/core/multiarray.so: undefined symbol: cblas_sgemm
I also tried to install from source instead of pip but no luck either.
The only way to get it to work is to downgrade to 1.9.1.
Any idea why?
Thanks.
Davide
