[vtkusers] new to vtk / python - some probs

[Dean Inglis]

Hi David,

copied all dlls to Python26/Lib/site-packages/vtk

but get

Traceback (most recent call last):
  File "Cone.py", line 13, in <module>
    import vtk
  File "C:\Python26\lib\site-packages\vtk\__init__.py", line 63, in <module>
    __helper.refine_import_err('rendering', 'vtkRenderingPython', exc)
  File "C:\Python26\lib\site-packages\vtk\__helper.py", line 32, in 
refine_impor
t_err
    raise LinkError, str(exc)
vtk.__helper.LinkError: DLL load failed: The specified module could not be 
found
.

same thing happened earlier when I set my path envar to point to the dll's 
in my
build tree.

Dean

>From the error that was reported, python seems to have located
vtkCommonPython.pyd but was not able to load vtkCommon.dll.
The VTK python install assumes that VTK itself has already been
installed, i.e. that the VTK DLLs are somewhere in the PATH.
You can copy the DLLsl into site-packages/vtk if you want the
python install of VTK to be fully self-contained.

Let me know what your experiences are when you try VTK/wxpython.
I'm not sure if it still works.
