[vtkusers] Trying to use VTK library in Python Interpreter

[Hesam]

Thanks for your instructions. Actually I need to have VTK itself in Python.
Let me explain a little more:

Consier I have 2 external vtk libraries in the same folder and I want to
import them into the Python. (i.e. "vtkCommonPython" and
"vtkFilteringPython") and both of them have .pyd and .dll files.
(vtkCommonPython.pyd and vtkCommonPythonD.dll and same for other one)

Despite they are in same folder when I write down

import vtkCommonPython

it is fine, however when I want to import the other one

import vtkFilteringPython
ImportError: DLL load failed: The specified procedure could not be found.

I tried also to find from where first library is loaded using

vtkCommonPython.__file__

And it was the same folder's path for the other one.

How I can trace the problem and find problem's source.
Thanks
Hesam
