What is the easiest way to install BLAS and LAPACK for scipy

Question

I would like to run a programme that someone else has prepared and it includes scipy  I have tried to install scipy with   pip install scipy   but it gives me a long error  I know there are ways with Anaconda and Canopy but I think these are long ways  I would like to have a short way  I have also tried   G  determinator Oskar gt pip install scipy Collecting scipy   Using cached scipy-0 16 1 tar

I got this problem on freeBSD  It seems lapack packages are missing  I solved it installing them  as root  with   pkg install lapack pkg install atlas-devel   not sure this is needed  but just in case   I imagine it could work on other system too using the appropriate package installer  e g  apt-get

For Debian Jessie and Stretch installing the following packages resolves the issue  sudo apt install libblas3 liblapack3 liblapack-dev libblas-dev   Your next issue is very likely going to be a missing Fortran compiler  resolve this by installing it like this  sudo apt install gfortran   If you want an optimized scipy  you can also install the optional libatlas-base-dev package  sudo apt install libatlas-base-dev  Source  If you have any issue with a missing Python h file like this   Python h  No such file or directory  Then have a look at this post  https   stackoverflow com a 21530768 209532

For windows  Best is to use pre-compiled package available from this site   http   www lfd uci edu  7Egohlke pythonlibs  scipy

Either use SciPy whl  download the appropriate one and run pip install  lt whl file gt   OR  Read through SciPy Windows issue and run one of the methods   OR   Use Miniconda   Additionally  install Visual C   compiler for python2 7 in-case it asks for it

The SciPy installation page already recommends several ways of installing python with SciPy already included  such as WinPython   Another way is to use wheels  a built-package format    pip install SomePackage-1 0-py2 py3-none-any whl   The wheel packages you can find on  http   www lfd uci edu  gohlke pythonlibs   For SciPy you need    the NumPy wheel packages and the SciPy wheel packages

Using conda install scipy instead of pip solved the problem for me

User · Answer

Why does a scipy get so complicated    It gets so complicated because Python s package management system is built to track Python package dependencies  and SciPy and other scientific tools have dependencies beyond Python  Wheels fix part of the problem  but my experience is that tools like pip virtualenv are just not sufficient for installing and managing a scientific Python stack   If you want an easy way to get up and running with SciPy  I would highly suggest the Anaconda distribution  It will give you everything you need for scientific computing in Python   If you want a  short way  of doing this  I m interpreting that as  I don t want to install a huge distribution    you might try miniconda and then run conda install scipy

For completeness  though this probably would not work well given your particular setup  external program   Windows   one can also acquire Scipy hassle-free as part of the  large  SageMath download

pip install Cython  before   pip install sklearn  did the trick for me

User · Answer

Always for Ubuntu Debian  chjortlund s answer it s very good but not perfect  since this way you get an unoptimized BLAS library  You have simply to do  sudo apt install libatlas-base-dev  and voila   Source
