[Paraview] [paraview] using with python to read file VTK in 3.7 and to show a volume representation

[BOUSSOIR Jonathan 167706]

Hi all,

I am new to paraview, I am using Linux. I read a lot of paraview emails this morning. I see you have been work hard last days on python script.
I download last version and compile.
Now I can read a file VTK surface sphere. But, I have still one error when I want to show my volume VTK file. I read a file then I tried to change the representation and I execute Render(), I have a problem : Cell Scalars not supported.

I link my VTK file in my email.
Thanks in advance for your kind help.

Regards, 
Jona

dp.Representation

dp.GetProperty("Representation").Available

dp.Representation = 'Volume'

Show(reader)
Render()
