Error importing vtkTkRenderWindowInteractor in vtk 8.2.0

Hi, David

Thank you so much for your help. After I turn on VTK_WRAP_PYTHON, I can see VTK_USE_TK in the list of parameters. And now I can find the libvtkRenderingPythonTkWidgets-8.2.so file under the VTK-build folder.

One more question, how could I let anaconda know now it should use the new built vtk, instead of the previous one build from conda?

Thanks.
