vtkBandedPolyDataContourFilter no input data when there is...
I'm running into an error with vtkBandedPolyDataContourFilter
for a specific source dataset (having trouble reproducing with other datasets)
import vtk
source = vtk.vtkDataSetReader()
source.SetFileName('ugrid.vtk')
surf = vtk.vtkDataSetSurfaceFilter()
surf.SetInputConnection(source.GetOutputPort())
contour = vtk.vtkBandedPolyDataContourFilter()
contour.SetInputConnection(surf.GetOutputPort())
contour.Update()

ERROR:root:No input data!
I've tried other pipelines that filter an unstructured grid which seeming work. I can't tell if something is wrong with this specific dataset or the vtkBandedPolyDataContourFilter
