I'm new to Python with a new windows 8 machine (64-bit OS).  Learning programming mainly for fun.  Naturally I downloaded Python 3.3 (who doesn't want the latest and greatest).  What I want involves functions related to the normal distribution. Based on my google research, it appears that SCIPY is a good way to go. That requires NUMPY.   I don't seem to find an install that works for my environment which leads to the questions on this post: Is there an install for my environment and if so, where do I get it? If not, is there another package I should use? Or do I need to bite the bullet and install an earlier version of Python.  Suggestions and comments appreciated. Thanks.

So what exactly went wrong when you tried to install this 
http://sourceforge.net/projects/numpy/files/NumPy/1.7.0/ using commands 
that you haven't given us and got error messages that you also haven't 
given us?

The setup of numpy-1.7.0 leads to a Setup window with a message: "Python 3.3 is required for this package. Select installation to use:". Below that is an empty list box.  Below that is an edit box for the Python Directory.  

I have Python 3.3 installed on c:\Python33.

Yes, you should have added this information. Are you sure that Python
3.3 is installed? Have you tried running it? e.g. when I run "python"
in my terminal I get:

oscar:~$ python
Python 2.7.3 (default, Sep 26 2012, 21:51:14)
[GCC 4.7.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>>

>From within Python I can also query the version:
>>> import sys
>>> sys.version
'2.7.3 (default, Sep 26 2012, 21:51:14) \n[GCC 4.7.2]'

Can you get similar output to confirm that Python 3.3 is installed?

I'm guessing that you installed a 64-bit python and are using a 32-bit numpy.

	Or they somehow found/built/installed a version of Python that did
not add itself to the Windows registry at all.

A casual google search seems to indicate that for now, SciPy and NumPy
are for Python 2.x (2.7 is the latest).  I could be wrong though and
often am.  I know a number of popular and useful packages are not yet
available on Python 3.

If you need to do a lot math stuff, there's a complete python system
that bundles a lot of these tools together into a nice package.  It's
called Sage.  http://www.sagemath.org/

There are several non-python packages out there that are really handy as
well:
- R - if you need to do statistics. http://www.r-project.org/
- Octave - a matlab-compatible language. http://www.gnu.org/software/octave/
- SciLab - a math package that has a nice gui. http://www.scilab.org

Rex,

A good start for supplementary packages is PyPi, see: 
http://en.wikipedia.org/wiki/Python_Package_Index

The packages in PyPi can be downloaded using easy-install, see: 
http://en.wikipedia.org/wiki/EasyInstall

Yes, the Enthught Numpy is a good starting point.

Good luck and have fun,

Colin W

My casual google search finds www.numpy.org as the first entry.
Clicking on the download link, one can find numpy 1.7.0 for Python 3.3
In all fairness, this was just released a few hours and is the first
official version supporting 3.3
However, numpy 1.6.2 did support 3.2
There's not yet a Scipy release supporting 3.3 so the OP may wish to
downgrade to Python3.2

Sage doesn't run natively on Windows. Not necessarily a problem but
should be mentioned.

What functions did you want? The math module contains the error
function erf() and the random module can generate normally distributed
pseudo-random numbers, e.g.:

>>> import math
>>> from math import erf
>>> erf(0.0)
0.0
>>> erf(1.0)
0.842700792949715
>>> from random import normalvariate
>>> normalvariate(0.0, 1.0)
-0.2793532098124607

There should be. Why doesn't it work?

numpy and scipy are both available for Python 3. They have been for
some time and, on Ubuntu, can be installed from the OS repositories.
For Windows the OP should use the sourceforge download page.

I am sure I have python installed. I have been running it. in command line the window title is c:\python33\python.exe.  The first line begins Python 3.3.0. Later in the line is the string "64 bit <AMD64>] on Win32".  

Thus it appears I am trying to run a 32bit numpy with a 64bit python.  (Seems like a big ole 64 bit python should be able to swallow a little 32 bitty numpy). Is there a 64bit numpy? If not why not? Can someone get on this? Seriously, I'm under the impression that I need the 64 bit python because I have a 64 bit OS.

Ask the numpy people. I am surprised since a reason to be using 64 
rather than 32 bit python is to have objects larger than 2 gigabytes and 
memory larger than 4 gigabytes. Numerical/scientific programming is 
relatively likely to need such.

If you look on your C: drive, you should have both 'Program Files' and 
'Program Files (x86)' directories. The latter is for 32 bit programs.

I can't answer the Numpy aspects, but I can tell you about 32bit versus 
64bit.

A 32 bit OS can only handle 32 bit applications.  It's conceivable to 
build a 32bit OS that will load and run 64bit apps, but it's probably 
impractical, and I don't know of anybody who has tried.

A 64bit OS can and does load both 32bit apps and 64bit apps.  But once 
it has loaded the app, the entire process has to be of the same 
"bittedness".  For Windows, that means any DLL's loaded from a 64bit 
process have to be 64bit, and any DLL's loaded from a 32bit process must 
be 32bit.

A python library may consist entirely of Python code, in which case it 
would work for either 32bit or 64bit Python installation.  But if the 
library includes DLL's (which Numpy certainly would) then there have to 
be separate versions of those DLL's.

Now, that library installation package may decide to include both sets 
of DLL's, and just install the appropriate ones at installation time. 
But that choice is entirely up to the library author.

I don't know why you feel the need to paraphrase this information
rather than simply paste the interpreter message into the email. The
latter would be more useful for others trying to help understand your
problem.

Because numpy/scipy make extensive use of Python's underlying binary
interfaces. These are incompatible between 32 and 64 bit Python.

Yes but most people who are doing that sort of thing would just
compile their own numpy/scipy and probably wouldn't be using Windows
for the their main computations anyway. Numpy does work on 64 bit
Python but official binaries are not distributed via the sourceforge
page. Unofficial binaries are available here:

I don't know about Windows 8 but I've used 32 bit Python on 64 bit XP
no problem. My impression was that 64 bit Windows (unlike OSX and most
Linux distros) ships with 32 bit duplicates of all its libraries so
that it can run 32 bit applications without modification. My Windows
usage significantly predates Windows 8, though so this may have
changed some time ago.
