I would like to install the scipy site package (not the entire scipy "stack"), and am looking for someone's advice (a brief how-to) who has done this before and not totally whacked their ArcGIS Python 2.7 install. Idealy I want scipy to be available to both the ArcGIS 32 and 64 bit installs of Python (C:\Python27\ArcGIS10.1 and C:\Python27\ArcGISx6410.1 respectively).I am assuming ArcGIS v10.1 SP1, Python 2.7.2, which is using numpy 1.6.1.I have tried installing both scipy v0.12 and v0.10.1 from http://sourceforge.net/projects/scipy/files/scipy/, and while many of the scipy functions work, the 'stats' submodule (scipy.stats - aka the one I actually want to use!!!) does not.When I was (1st) trying this with scipy v0.12 I got the error:>>> from scipy import stats
Traceback (most recent call last):
File "<interactive input>", line 1, in <module>
File "C:\Python27\ArcGIS10.1\lib\site-packages\scipy\stats\__init__.py", line 320, in <module>

Upon some advice here: http://forums.arcgis.com/threads/91254-ArcGIS-10.1-Python-crash-on-quot-import-arcpy-quot-after-inst..., I downgraded to scipy v0.10.1 and now get a more exciting error (relating to numpy datatypes, but at least it seems to be getting closer!)>>> from scipy import stats

Anyone have any advice? Jason S.? Luke P.? or ???
