[Numpy-discussion] need advice on installing NumPy onto a Windows 7 with Python2.7 (32-bit)

[William McLendon]

Hi,

I am trying to install NumPy (using  numpy-1.6.1-win32-superpack-python2.7) on a Windows 7 machine that has 32-bit Python 2.7 installed on it using the latest installer (python-2.7.2.msi).  Python is installed into the default location, C:\Python27, and as far as I can tell the registry knows about it -- or at least the windows uninstaller in the control panel does...

The installation fails because the NumPy installer cannot find the Python installation.  I am then prompted with a screen that should allow me to type in the location of my python installation, but the text-boxes where I should type this do not allow input so I'm kind of stuck.

I did look into trying to build from source, but I don't have a C compiler on this system so setup.py died a horrible death.  I'd prefer to avoid having to install Visual C++ Express on this system.

Does anyone have any suggestions that might be helpful?

Thanks!

To avoid all the hassle I suggest getting EPD: http://enthought.com/products/epd.php

You'd get way more than just NumPy, which may or may not be what you need. 

I have installed various NumPy's on linux only and from source only which did 

require compilation (gcc), so I am not a good help for your setup. 

On the hand, I've done multiple EPD installations on various platforms and never had problems.

It seems weird that it wouldn't work, as this is a pretty standard setup. Here's a few ideas of things to check:
- Double-check it's really 32 bit Python (checking sys.maxint)
- Is there another Python installation that may cause some conflicts?
- Did you download the numpy superpack from the official website?
- Reboot

Unlikely to be helpful, but I can't think of something else right now :/

Yup, it's 32-bit python:

Python 2.7.2 (default, Jun 12 2011, 15:08:59) [MSC v.1500 32 bit (Intel)] on win32
Type "copyright", "credits" or "license()" for more information.
>>>

I've only got one python instance installed here :D

Here's where I got the numpy installer, http://sourceforge.net/projects/numpy/files/NumPy/1.6.1/, as far as I can tell this should be the right place.

Python has been installed on this system for a while and it's been rebooted numerous times, I can't imagine that it wouldn't be there.  Matplotlib's installer had no trouble finding Python.

Thanks!

Sorry then, I'm afraid I'm out of (simple ideas). Out of curiosity, I tried to install Python 2.7.2 and numpy 1.6.1 on a Windows 7 computer and it worked just fine, so it must be something with your specific setup...
