problem in dragon demo

I am learning to use paraview and ttk. I am stuck with dragon example itself.

I am watching youtube video on ttk official site and when i click persistence threshold i get this error

can anyone help me please


Hello @Pravin_Poudel ,
Thanks for your interest in TTK, can you provide the version of ParaView you are using ?
Also, do you use the provided TTK or a compiled one ?
Finally, do you load the state from the TTK data repository ?

@julien-tierny may also help here :slight_smile:
