Hey, thanks to help me with that.
I started fresh to have a truly reproducible process,
so you can have all information and rule out some error possibilities.

  - Uninstall all python.
  - Check that PythonPath doesn't exist anymore
  - check that python doesn't exist anymore

  - install python 3.2.5 64 bit from official python website into C/Python32

  - Reload configuration for server.

  - create plpython3u , create a python function, test it (show path)

    * It works, python path is
     'C:\\Windows\\system32\\python32.zip', 'C:\\Python32\\Lib',
'C:\\Python32\\DLLs', 'E:\\9.3\\data', 'C:\\Program
Files\\PostgreSQL\\9.3\\bin', 'C:\\Python32',
'C:\\Python32\\lib\\site-packages'

  - Donwload latest numpy from website.
  - ON antoher PC

So what is the Python setup on this machine?

    * Compile numpy with visual 2008 , 64 bit
    * Create an binary installer for windows (using python.exe setup.py
)with proper argument

The argument would be?

  - On the server :
  - install numpy with the compiled installer.

Best guess is that the numpy compilation you are doing on Machine A is not compatible with what you have installed on Machine B(the server).

Have you looked at this:
http://www.lfd.uci.edu/~gohlke/pythonlibs/

or

http://www.scipy.org/install.html

  - check that numpy is correctly installer in C:\Python32\Lib\site-packages
  - using an external terminal, check that numpy works (import numpy -> OK)

  - Now, define a plpython3u function containing "import numpy"

  - Run the function --> error is
   "ERREUR:  ImportError: DLL load failed: Le module spécifié est
introuvable.",
    which roughly translate to
   "ERROR: ImportError : DLL load failed : the specified module couldn't
be found".

  - Create a plpython3u function returning sys.path
the path is "C:\\Windows\\system32\\python32.zip', 'C:\\Python32\\Lib',
'C:\\Python32\\DLLs', 'E:\\9.3\\data', 'C:\\Program
Files\\PostgreSQL\\9.3\\bin', 'C:\\Python32',
'C:\\Python32\\lib\\site-packages"
numpy is in this path, in C:\\Python32\\lib\\site-packages
All user of the computer have all rights on the
C:\\Python32\\lib\\site-packages folder


  - execute `import imp; imp.find_package('numpy')` within the
plpython3u function
    -> returns "None, 'C:\\Python32\\lib\\site-packages\\numpy', ('',
'', 5)"

  - create a helloworld module , put it next to numpy, try to call it
    -> it gets called

I really don't see what I can do more.

Cheers,
Rémi-C
