Hi Frank, I didn't have a problem with the following on my windows machine using the ParaView 3.14.1 installer. ======= try: paraview.simple
except: from paraview.simple import * paraview.simple._DisableFirstRenderCameraReset() Wavelet1 = Wavelet() RenderView1 = GetRenderView() ProgrammableFilter1 = ProgrammableFilter() ProgrammableFilter1.PythonPath = '' ProgrammableFilter1.RequestInformationScript = '' ProgrammableFilter1.Script = 'x = inputs[0].PointData[\'RTData\']\nprint "x shape =",x.shape\n\nm = x*x # I _thought_ this should run at numpy speeds?\nprint "m shape=",m.shape\n\n# more debugging code to finish computation of the norm omitted\n\noutput.PointData.append(m,"Displacement Norm")' Show() Render() ============= Does this work for you? If it doesn't, I wonder if it's an issue with having multiple pythons and numpy or system environments causing problems. What version of paraview are you using and how did you get it built/installed on your machine?
