'pysplishsplash.Exec.SimulatorBase' object has no attribute 'VTK_EXPORT'

Hi
I want to run the following code in the documentation. It intends to run the python binding with VTK output.

import pysplishsplash as sph
from pysplishsplash.Extras import Scenes
import os

def main():
    base = sph.Exec.SimulatorBase()
    output_dir = os.path.abspath("where/you/want/the/data")
    base.init(useGui=False, outputDir=output_dir, sceneFile=Scenes.DoubleDamBreak)
    base.setValueFloat(base.STOP_AT, 20.0) # Important to have the dot to denote a float
    base.setValueBool(base.VTK_EXPORT, True)
    # Uncomment the next line to set the output FPS value (must be float)
    # base.setValueFloat(base.DATA_EXPORT_FPS, 10000.) 
    base.run()

if __name__ == "__main__":
    main()

However, I got this error.
