Re: python-scipy
One interesting thing:
/usr/lib/python3.6/site-packages/numpy/distutils/system_info.py:572: UserWarning:
*********************************************************************
Could not find lapack library within the ATLAS installation.
*********************************************************************
So maybe it's an Atlas problem. This may also explain problems with other math related
packages?

Re: python-scipy
Hmm, there is no such thing as python-atlas. Honestly, I have no idea about python packaging

Re: python-scipy
No, there isn't, Atlas is the C math library underneath.
As I understood strange stuff is happending in python-scipy when probing for math libraries like atlas, blas, lapack, etc

Re: python-scipy
I know it from Armadillo (a c++ wrapper for math libraries). They use Fortran or C code from very
old libraries and provide a consistent wrapper on top. For certain algorithms it's crutial to pick
the right library (for performance and test result reasons).
Something similar must happen in python-scipy..
