Installing scipy in Python 3.5 on 32-bit Windows 7 Machine

Make sure you pay attention to this line from the link you provided:

Many binaries depend on NumPy-1.9+MKL and the Microsoft Visual C++
2008 (x64, x86, and SP1 for CPython 2.6 and 2.7), Visual C++ 2010
(x64, x86, for CPython 3.3 and 3.4), or the Visual C++ 2015 (x64 and
x86 for CPython 3.5) redistributable packages.

Download the corresponding Microsoft Visual C++ Redistributable Package which should be this one based on your description.

I had a similar problem, can't recall the exact issue, and I download the one for my system and it worked fine. Let me know otherwise.

Installing NumPy and SciPy on 64-bit Windows (with Pip)

EDIT: The Numpy project now provides pre-compiled packages in the wheel format (package format enabling compiled code as binary in packages), so the installation is now as easy as with other packages.

---

Numpy (as also some other packages like Scipy, Pandas etc.) includes lot's of C-, Cython, and Fortran code that needs to be compiled properly, before you can use it. This is, btw, also the reason why these Python-packages provide such fast Linear Algebra.

To get precompiled packages for Windows, have a look at Gohlke's Unofficial Windows Binaries or use a distribution like Winpython (just works) or Anaconda (more complex) which provide an entire preconfigured environment with lots of packages from the scientific python stack.

How do I install SciPy on 64 bit Windows?

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.

Can't install Scipy through pip

After opening up an issue with the SciPy team, we found that you need to upgrade pip with:

pip install --upgrade pip

And in Python 3 this works:

python3 -m pip install --upgrade pip

for SciPy to install properly. Why? Because:

Older versions of pip have to be told to use wheels, IIRC with --use-wheel. Or you can upgrade pip itself, then it should pick up the wheels.

Upgrading pip solves the issue, but you might be able to just use the --use-wheel flag as well.

Trouble installing SciPy on windows

To install SciPy on Windows you have to have a fortran compiler installed. The SciPy project recommends MinGW. See Building and installing SciPy. To install MinGW follow these instructions: HOWTO Install the MinGW (GCC) Compiler Suite. Then before you run pip or easy_install to install SciPy make sure that you have MinGW added to your path. See MinGW Installation Notes - Environmental Variables

A side note, It would be easier to use either the Enthought Distribution (part of the initial install) or the Active State Distribution (through pypm 32-bit only) as they already have precomiled binary packages for SciPy. Or, you could use the SciPy precompiled binary package installer for Windows.

Installing SciPy with pip

An attempt to easy_install indicates a problem with their listing in the Python Package Index, which pip searches.

easy_install scipy
Searching for scipy
Reading http://pypi.python.org/simple/scipy/
Reading http://www.scipy.org
Reading http://sourceforge.net/project/showfiles.php?group_id=27747&package_id=19531
Reading http://new.scipy.org/Wiki/Download

All is not lost, however; pip can install from Subversion (SVN), Git, Mercurial, and Bazaar repositories. SciPy uses SVN:

pip install svn+http://svn.scipy.org/svn/scipy/trunk/#egg=scipy

Update (12-2012):

pip install git+https://github.com/scipy/scipy.git

Since NumPy is a dependency, it should be installed as well.
