Question #404172 on Yade changed:
https://answers.launchpad.net/yade/+question/404172

    Status: Open => Answered

Jan Stránský proposed the following answer:
Hi Weimin,
it should be either

vtkExporter = export.VTKExporter(...)
vtkExporter.export...

or

export.VTKExporter(...).export...

anyway it is VTKExporter (with capital VTK) and it has to be initialized
(called as VTKExporter(fileName)   ) to work.

cheers
Jan
