Hello everyone  
I am trying to use vtk in google [colab](https://colab.research.google.com)  
My tests with simplest vtk code such as [circle](https://kitware.github.io/vtk-examples/site/Python/GeometricObjects/Circle/) is returning the crush of kernel each time with an unknown error.  
I traced back the line that the code crushes with following line: `renderWindow.Render()`

Does anyone has any experience whether vtk run in google collaboration properly at all? Below is the full code of the example from vtk website:

It is probably a rendering issue (no gpu) and you need to make sure you use a VTK that was built with OSMesa (OffScreen Mesa).

You should be able to set up a display server and use that. I haven’t done it myself but you can find many potential solutions if you google for `google colab x server`.
