Not able to install the python-module numpy

Question

After hours of trying I'm still not able to install numpy. I READ LOTS OF HINTS, ANSWERS USW. BUT IT DOESN'T HELP. Furthermore I have windows 7, 32 bit, Python 27.

What I did:

download numpy-1.10.2.zip: http://sourceforge.net/projects/numpy/files/
unzip it
start the windows command prompt and input: cd C:\Users\myname\Desktop\numpy-1.10.2
now it appears: C:\Users\myname\Desktop\numpy-1.10.2>
I input: python setup.py install

and there appears an error:

Running from numpy source directory.
Traceback (most recent call last):
File "setup.py", line 263, in <module>
    setup_package()
File "setup.py", line 246, in setup_pa
    import setuptools
ImportError: No module named setuptools

I hope somebody can help me or even better IS THERE NOT EASIER WAY TO INSTALL NUMPY OR OTHER MODULES??

Easier way - use Anaconda (or another distribution).

Building numpy from source on windows is non-trivial. Best use official binaries (http://sourceforge.net/projects/numpy/files/NumPy/1.10.2/) or Gohlke binaries (http://www.lfd.uci.edu/~gohlke/pythonlibs/#numpy) or a distribution like Anaconda or Canopy or WinPython.

Building basic NumPy isn't hard on Windows, at least not for 2.7 or 3.5 (3.4 is a chore). Install C++ compiler for Python 2.7 or Visual Studio Community for 3.5. Then use pip to build a wheel. However, Microsoft doesn't distribute a Fortran compiler to build LAPACK, so the resulting NumPy lacks accelerated linear algebra. You need the MinGW or Intel toolchain for Fortran. Save yourself the hassle and get a pre-built package as ev-br suggests.

thanks for the quick answert. i still cant install numpy. for me it is necessary that you explain it more detailed. best you guess i have no idea from installing modules! so to your first hint: i used the official binaries (see my link above) but it doesnt work... and maybe you can tell me how Anaconda can help me to install numpy? I don’t have any idea how to install it, because i am the opposite of a profi ;-), can you give me a little bit exacter answers??

ev-br Over a year ago

Your link was that you downloaded the source and tried compiling it. For that, you need what e.g. @eryksun said. It's simpler to download an exe installer, run that and follow the prompts.

Hallelujah, finally there is a simple way, exe installer sounds great :-D But I could not find one, maybe somebody have a hint (or even better a link) where I can download a exe-file which installs numpy??

Now it has worked :-D, I could find an exe-file thx for your help!

You need to install the setuptools package as well. See here.

A more easy way to install python packages is using pip, which resolves package dependencies automatically. See here. Pip should be included in your python installation if you use a recent version.

You should succeed by calling pip install numpy.

That almost certainly won't work - the OP would need to have a working toolchain in order build the C extensions, which is not straightforward to set up on Windows.
