vtk9 branch error for the GUI

[HernandoMV]

Initializing the GUI throws this error in the vtk9 branch (used it due to closePlotter issues in the main branch, that are caused by the non-installation of the newest version)

KeyError: 'notebookBackend'

NotebookBackend error replicated with this:

from brainrender import Scene
from vedo import embedWindow, Plotter, show  # <- this will be used to render an embedded scene 
from itkwidgets import view
embedWindow(None)  # <- this will make your scene popup

from brainrender import Scene

popup_scene = Scene(title='popup')

popup_scene.render()  # press 'Esc' to close!!

New updates. Tried with fresh environment in python3.8, installing the vtk9 branch, and I get the exact same errors

Hernando, please downgrade vedo to pip install vedo==2021.0.5, more recent versions are no longer supported. With that version it should all work correctly, let me know!
