Interact() crash the second time in pvpython

ParaView Support

I’m using pvpython trying to replicate (without much success) work than in ParaView.

Right now I’m having trouble with pvpython and the funcion Iteract(), after closing the interact windows it doesn’t open again. Is this correct? How can I do this?

➜  ~ /Applications/ParaView-5.7.0.app/Contents/bin/pvpython ; exit;

>>> from paraview.simple import *
>>> cylinder2 = Cylinder()
>>> cylinder2.Resolution = 6
>>> cylinder2.Height = 1.0
>>> cylinder2.Radius = 0.5
>>> cylinder2.Center = [0.0, 0.0, 0.0]
>>> cylinder2.Capping = 1
>>> renderView1 = GetActiveViewOrCreate('RenderView')
>>> cylinder2Display = Show(cylinder2, renderView1)
>>> Interact()
>>> cylinder2.Resolution = 50
>>> Interact()

In mac I don’t get any message error, in Windows 10 I get

I can’t reproduce on Linux.

More Info: this was tested with pvpython that comes with ParaView 5.6.2 in Windows 10 and with the pvpython that comes with ParaView 5.7 in mac with the same result

Okay. If I press ‘q’ on the windows and do something like

render_window = renderView1.GetRenderWindow()
render_window.Finalize()

then I can do Interact() again. I guess this is the desired behavior.

Closing the window is indeed not supported currently. You can quit the interactor loop – as you discovered – by hitting the q key. The window.Finalize call should not be necessary.
