[Python.NET] Using numpy/matplotlib - DLL Load Failed

[Tribble, Brett]

Check to make sure that your pythonpath and system path are the same after you import the CLR. In other words, what are both of these set to when it works, and when it fails. Perhaps Barton has some idea what causes the underlying error.

I have tried, as you mentioned, importing multiarray first. It is a module
declared in numpy.core (the filename is "multiarray.pyd") though I keep
getting the same error. Any idea what else I might try? 

>>> from numpy.core import multiarray
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "c:\python27\lib\site-packages\numpy\__init__.py", line 142, in
<module>
    import add_newdocs
  File "c:\python27\lib\site-packages\numpy\add_newdocs.py", line 9, in
<module>

    from numpy.lib import add_newdoc
  File "c:\python27\lib\site-packages\numpy\lib\__init__.py", line 4, in
<module

    from type_check import *
  File "c:\python27\lib\site-packages\numpy\lib\type_check.py", line 8, in
<modu
le>
    import numpy.core.numeric as _nx
  File "c:\python27\lib\site-packages\numpy\core\__init__.py", line 5, in
<modul

    import multiarray
ImportError: DLL load failed: The specified module could not be found.
