Hey Dave,
I don't have a good explanation (just through my ignorance), but the
problem seems to be how you are importing the VTK modules in your
script, not in the VTK installation.
When I run the script that you supplied in an earlier thread, I get
the same error you do, but if I change the import statements to the
standard "import vtk" (and add vtk. before the vtk classes, after
which you shouldn't need to do that PYTHONPATH export), then it runs
just fine on my machine, including printing out the number of polys.
Here's the modified script -- good luck.
-Eric
