Widget: model not found when using jupyter notebook lab

[adam2392]

I'm currently using a Mac OSX and trying to plot some stuff that relies on ipyvtklink to render something in the notebook. This is an issue started in https://github.com/mne-tools/mne-python/issues/9393

I get this error where I'm getting a "model not found". Untitled.pdf

Unfortunately, I have no idea how to proceed further on diagnosing this error and was wondering if anyone might have some ideas?

@adam2392 could you also confirm that you reproduce the issue with a simple example like the one on the README.md ?

import vtk
from ipyvtklink.viewer import ViewInteractiveWidget

# Create some data
cylinder = vtk.vtkCylinderSource()
cylinder.SetResolution(8)
mapper = vtk.vtkPolyDataMapper()
mapper.SetInputConnection(cylinder.GetOutputPort())
actor = vtk.vtkActor()
actor.SetMapper(mapper)

# Set up render window
ren = vtk.vtkRenderer()
ren_win = vtk.vtkRenderWindow()
ren_win.SetOffScreenRendering(1)
ren_win.SetSize(600, 600)
ren_win.AddRenderer(ren)
iren = vtk.vtkRenderWindowInteractor()
iren.SetRenderWindow(ren_win)
style = vtk.vtkInteractorStyleTrackballCamera()
iren.SetInteractorStyle(style)

# Add actor to scene
ren.AddActor(actor)
ren.ResetCamera()

# Display
ViewInteractiveWidget(ren_win)

yep just tried and got the same thing :/

I'm hoping this issue resolved itself -- these errors tend to no longer be an issue (for me) in Jupyter Lab >=3
