[SciPy-User] SciPy under Windows 7 (x64)

[Donovan Parks]

Hello,

I recently moved to Windows 7 (x64) and am having trouble with SciPy
(or perhaps NumPy). I'm using Python 2.6.4, the
scipy-0.7.1-win32-superpack-python2.6.exe for SciPy, and the
numpy-1.4.0rc1-win32-superpack-python2.6.exe for NumPy. A simple
example of SciPy/NumPy not working is as follows:

>>> from scipy.stats import chi2
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "D:\Python26\lib\site-packages\scipy\stats\__init__.py", line
7, in <module>
    from stats import *
  File "D:\Python26\lib\site-packages\scipy\stats\stats.py", line 203,
in <module>
    from morestats import find_repeats #is only reference to scipy.stats
  File "D:\Python26\lib\site-packages\scipy\stats\morestats.py", line
7, in <module>
    import distributions
  File "D:\Python26\lib\site-packages\scipy\stats\distributions.py",
line 27, in <module>
    import vonmises_cython
  File "numpy.pxd", line 30, in scipy.stats.vonmises_cython
(scipy\stats\vonmises_cython.c:2939)
ValueError: numpy.dtype does not appear to be the correct type object

Do I need to build NumPy and SciPy from source for them to work under
Windows 7 (x64)? or is there a way I can use easy_install?

Cheers,
Donovan
