pcl_with_pyqt5.py crashing with error code -1073741819 (0xC0000005)

Hi,

I have pclpy v0.11.0 and vtk 8.1.2 installed running on python 3.6.8. My configuration can run all of the pclpy test files just fine. But I'm having some problems running the pcl_with_pyqt5.py example file. Whenever I tried running it, it crashes with error code

-1073741819 (0xC0000005)

. I tracked the problem down to the line

self.vtk_widget = QVTKRenderWindowInteractor(self, rw=window)

where self._Iren.SetRenderWindow(self._RenderWindow) from the QVTKRenderWindowInteractor() function is the line that is throwing the exception. Does anyone know how to resolve this? I'd love to use this example as a guide to embed PCL graphics into an Qt application. Any help would be greatly appreciated.

Thanks!

I compiled it using vtk binaries from conda... You can try that.

The VTK viewer is good for light point clouds only... Don't get too high hopes :)
