Binary installers¶In most use cases the best way to install NumPy on your system is by using aninstallable binary package for your operating system.
@rgommers i'm quite sure this isn't a dup of that, i'm running on mac os x and afaik it uses Accelerate.framework in LAPACK. Also i seem to judge the severity of this a bit different: Many of my researcher colleagues use macs and all of whom I asked to run the scipy test were surprised that these tests fail. I'm not 100% sure how bad the errors actually are, but i get a bad feeling that many. Scipy library main repository. Contribute to scipy/scipy development by creating an account on GitHub. Remember, to install from source, the sub-packages need to have their developer modules (headers) installed as well. Even if you have blas/lapack installed, you probably don't have the headers needed, which is what configure is looking for.
Windows¶Good solutions for Windows are, The Enthought Python Distribution (EPD) (which provides binaryinstallers for Windows, OS X and Redhat) and Python (x, y). Both of these packages include Python, NumPy andmany additional packages.
A lightweight alternative is to download the Pythoninstaller from www.python.org and the NumPyinstaller for your Python version from the Sourceforge download site
The NumPy installer includes binaries for different CPU's (without SSEinstructions, with SSE2 or with SSE3) and installs the correct oneautomatically. If needed, this can be bypassed from the command line with
Fayol principle in hindi. or ‘sse2' or ‘sse3' instead of ‘nosse'.
Linux¶Most of the major distributions provide packages for NumPy, but these can lagbehind the most recent NumPy release. Pre-built binary packages for Ubuntu areavailable on the scipy ppa. Redhat binaries areavailable in the EPD.
Mac OS X¶A universal binary installer for NumPy is available from the download site. The EPDprovides NumPy binaries.
Hi, I'm brand new when it comes to BLAS and LAPACK and could use some help.
Ultimately I'm trying to install both so that I can use the LA packages (as a library) with Fortran 77 code compiled with gfortran. I'm using Maz OS X 10.6.8 and am attempting to install lapack version 3.5.0
Initially I followed the instructions given here: http://gcc.gnu.org/wiki/GfortranBuild for BLAS and LAPACK installation, but on getting some errors switched to the instructions given here: http://pheiter.wordpress.com/2012/09/04 .. on-mac-os/ and followed them exactly. To save you clicking on the link: 
Both packages are required when you deal with linear algebra operations, e.g. solving linear equation systems. Originally, both packages were written in FORTRAN, but I want to use them coding in C++. The solution is to create a libraray! There're a few steps to consider while installing the packages. First, you have to install BLAS, because LAPACK requires it. If you have downloaded both packages, unzip them. Switch to the BLAS folder and execute
$ make 
to compile all fortran files. After that, execute
 $ mv blas_UNIX.a libblas.a
to rename the created library. Now, you created a library called 'libblas.a'. You just copy that file to your library folder. Therefore execute the following command
 sudo cp libblas.a /usr/local/lib/
Et voila. You've installed the BLAS package. Now switch to the LAPACK folder and adjust the file 'make.inc'. If you set all parameter correctly, execute the command
 $ make

My BLAS directory is Users/username/BLAS, LAPACK is users/username/lapack-3.5.0
In my make.inc file 
Code: Select allBLASLIB = libblas.a Everything else is as it was when I d/l'ed it.
Having done all that the errors in the testing that caused me to switch to the other installation instructions when I run make are still there, and I've been unable to find useful references to them on the web:
( cd INSTALL; make; ./testlsame; ./testslamch; ./testdlamch; 
 ./testsecond; ./testdsecnd; ./testieee; ./testversion )

So, I'm at a loss and could do with some direction. I'm not even sure if this is at all important to be honest, so any insight would be welcome.

Thanks in advance,
