Okay a lot has been said  but just in case nothing of the previous answers work  you can try  https   www scipy org install html According to them   For most users  especially on Windows  the easiest way to install the packages of the SciPy stack is to download one of these Python distributions  which include all the key packages   Anacond  A free distribution for the SciPy stack  Supports Linux  Windows and Mac  Enthought Canopy  The free and commercial versions include the core SciPy stack packages  Supports Linux  Windows and Mac  Python x y  A free distribution including the SciPy stack  based around the Spyder IDE  Windows only  WinPython  A free distribution including the SciPy stack  Windows only  Pyzo  A free distribution based on Anaconda and the IEP interactive development environment  Supports Linux  Windows and Mac    Still for me  Anaconda did solve this problem  Do remember to check the bit  32 64 bit  version before downloading and re-adjust your compiler to the Python implementation installed with the Python distribution you are installing

Short answer  Windows 64 bit support is still work in progress at this time  The superpack will certainly not work on a 64-bits Python  but it should work fine on a 32 bits Python  even on Windows 64 bit    The main issue with Windows 64 bit is that building with mingw-w64 is not stable at this point  it may be our s  NumPy developers  fault  Python s fault or mingw-w64  Most likely a combination of all those     So you have to use proprietary compilers  anything other than the Microsoft compiler crashes NumPy randomly  for the Fortran compiler  ifort is the one to use  As of today  both NumPy and SciPy source code can be compiled with Visual nbsp Studio nbsp 2008 and ifort  all tests passing   but building it is still quite a pain  and not well supported by the NumPy build infrastructure

Another alternative  http   www pythonxy com   Free and includes lots of stuff meant to work together smoothly   This person says      Did you try linux pythonxy     http   linux pythonxy com         It s 64 bit ready       Though I m not quite sure what that means   Update   This appears to be dead  I use Anaconda now  which has 32-bit or 64-bit installers

I have a 32-bit Python 3 5 on a 64-bit Windows  8 1 machine  I just tried almost every way I can find on Stack  Overflow and no one works  Then on here I found it  It says   SciPy is software for mathematics  science  and engineering  Requires numpy mkl  Install numpy mkl before installing scipy   mkl matters   But nobody said anything about that before  Then I installed mkl  C  Users      Desktop a gt  pip install mkl service-1 1 2-cp35-cp35m-win32 whl Processing c  users      desktop a mkl service-1 1 2-cp35-cp35m-win32 whl Installing collected packages  mkl-service Successfully installed mkl-service-1 1 2  Then I installed SciPy  C  Users      Desktop a gt pip install scipy-0 18 1-cp35-cp35m-win32 whl Processing c  users      desktop a scipy-0 18 1-cp35-cp35m-win32 whl Installing collected packages  scipy Successfully installed scipy-0 18 1  It worked  yeah    A tip  You can just google  quot whl file name whl quot  to know where to download it     Update  After all these steps you will find that you still can not use SciPy in Python  3  If you print  quot import scipy quot  you will find there are error messages  but don t worry  there is only one more thing to do  Here       just comment out that line  simple and useful  from numpy  distributor init import NUMPY MKL  I promise that it is the last thing to do     PS  Before all these steps  you better install NumPy first  That s very simple using this command  pip install numpy

Okey  here I am going to share what I have done to install SciPy on my Windows PC without the command line      My PC configuration is Windows 7 64-bit and Python 2 7    First  I download the required packages form  http   www lfd uci edu  gohlke pythonlibs   which version match your configuration EX  cp27   python2 7  amp  cp35   3 5  Second  I extract the file using 7-Zip  also can be used any zipper like WinRAR  Third I copy the scipy folder which I extracted and paste it into C  Python27 Lib site-packages  or put it where the exact location is in your PC like       Lib site-packages       NOTE  You have to install NumPy first before installing SciPy in this same way

You can either download a scientific Python distribution  One of the ones mentioned here  https   scipy org install html  Or pip install from a whl file here if the above is not an option for you   http   www lfd uci edu  gohlke pythonlibs  scipy

For completeness   Enthought has a Python distribution which includes SciPy  however  it s not free   Caveat   I ve never used it   Update  This answer had been long forgotten until an upvote brought me back to it   At this time  I ll second endolith s suggestion of Anaconda  which is free

I was getting this same error on a 32-bit machine   I fixed it by registering my Python installation  using the script at   http   effbot org zone python-register htm   It s possible that the script would also make the 64-bit superpack installers work

I haven t tried it  but you may want to download this version of Portable Python  It comes with Scipy-0 7 0b1 running on Python 2 5 4

WinPython is an open-source distribution that has 64-bit NumPy and SciPy

User · Answer

Unofficial 64-bit installers for NumPy and SciPy are available at http   www lfd uci edu  gohlke pythonlibs   Make sure that you download  amp  install the packages  aka  wheels  that match your CPython version and bitness  ie  cp35   Python v3 5  win amd64   x86 64    You ll want to install NumPy first   From a CMD prompt with administrator privileges for a system-wide  aka  Program Files  install   C   gt pip install numpy- lt version gt  mkl-cp lt ver-spec gt -cp lt ver-spec gt m- lt cpu-build gt  whl   Or include the --user flag to install to the current user s application folder  Typically  APPDATA  Python on Windows  from a non-admin CMD prompt   C   gt pip install --user numpy- lt version gt  mkl-cp lt ver-spec gt -cp lt ver-spec gt m- lt cpu-build gt  whl   Then do the same for SciPy   C   gt pip install  --user  scipy- lt version gt -cp lt ver-spec gt -cp lt ver-spec gt m- lt cpu-build gt  whl   Don t forget to replace  lt version gt    lt ver-spec gt   and  lt cpu-build gt  appropriately if you copy  amp  paste any of these examples   And also that you must use the numpy  amp  scipy packages from the ifd uci edu link above  or else you will get errors if you try to mix  amp  match incompatible packages -- uninstall any conflicting packages first  ie  pip list

As the transcript for SciPy told you  SciPy isn t really supposed to work on Win64   Warning  Windows 64 bits support is experimental  and only available for testing  You are advised not to use it for production    So I would suggest to install the 32-bit version of Python  and stop attempting to build SciPy yourself  If you still want to try anyway  you first need to compile BLAS and LAPACK  as PiotrLegnica says  See the transcript for the places where it was looking for compiled versions of these libraries

User · Answer

Try to install Python 2 6 3 over your 2 6 2  this should also add correct Registry entry   or to register your existing installation using this script  Installer should work after that   Building SciPy requires a Fortran compiler and libraries - BLAS and LAPACK

Install a Python distribution  http   www python org download    Download and install the Anaconda Python distribution   Make the Anaconda Python distribution link to Python nbsp 3 3 if you want NumPy  SciPy or Matplotlib to work in Python nbsp 3 3  or just use it like that to have only Python nbsp 2 7 and older functionality   The blog post Anaconda Python Distribution Python 3 3 linking provides more detail about Anaconda

It is terrible to install such Python data science packages independently on Windows  Try Anaconda  one installer  400 more Python packages  py2  amp  py3 support   Anaconda really helps me a lot
