[Python.NET] Uses PythonNet with current Python installation

[thane at magna-capital.com]

I'm not sure why, but copying the PythonNet DLLs (CLR.dll and
Python.Runtime.dll) to a standard CPython installation directory, does not
give the CPython "real" access to the CLR.

 

Two observations:

1.       The CLR modules don't load on the first try (see output below), and

2.       Running modules that require the CLR will sometimes fail (I'll
investigate this some more).  I've written a .Net backend for matplotlib,
which runs fine with the Python distribution from PythonNet (Brian's
distribution), but it crashes when the DLLs are in the CPython distribution
from Python.org.  I'm stumped. could it be related to the "loading delay"
above?

 

Any ideas?
