In terminal, it occurs when run python3 and import vtk after compiling VTK 8.2 branch in Mac mini and run ‘make install’.

I don’t think `vtkRendingQt` is a module or class in VTK at all… perhaps you’re looking for the `vtk.qt` module?:

```auto
import vtk.qt

from vtk.qt.QVTKRenderWindowInteractor import QVTKRenderWindowInteractor

```

Do you have any other context on what you’re trying to accomplish?

Enter import vtk in python to report this error, but there is vtkRenderingQTPython in vtkmodules

That’s not good!

Do you have `PyQt5` installed?

```bash
python3 -m pip install PyQt5

```

Also - is there any reason your building VTK from source and not using the PyPI wheels?

See [this question](https://discourse.vtk.org/t/after-building-vtk8-2-0-and-building-vtkmaster-there-are-different-errors-after-make-install/525/2) which has a similar error.
