v.view(interactive=True) causes kernel to die on BinderHub

[matthewfeickert]

@stewartboogert a note for the future, probably too late to revise it today, is that the cell in the notebook that contains

import numpy as _np
reg = _g4.Registry()
reg.clear()

worldSize = _gdml.Constant("boxSize", 200, reg)
boxSize = worldSize/20

# materials 
worldMaterial = _g4.nist_material_2geant4Material("G4_Galactic", reg)
boxMaterial   = _g4.nist_material_2geant4Material("G4_Au", reg)

# solids 
worldSolid = _g4.solid.Box("ws", worldSize, worldSize, worldSize, reg, "mm")
boxSolid = _g4.solid.Box("bs", boxSize, boxSize, boxSize, reg, "mm")

ringRadius = _gdml.Constant("ringSize", 50, reg)

# structure
worldLogical = _g4.LogicalVolume(worldSolid, worldMaterial, "worldLogical", reg)
boxLogical   = _g4.LogicalVolume(boxSolid, boxMaterial, "boxlogical", reg)

for i in range(0,20,1) :
    ic = _gdml.Constant("i_"+str(i),i/20,reg)
    phi = 2*_np.pi*ic
    x = ringRadius*_gdml.cos(phi)
    y = ringRadius*_gdml.sin(phi)
    
    boxPhysical  = _g4.PhysicalVolume([0, 0, -phi], [x, y, 0], boxLogical, "boxPhysical_"+str(i), worldLogical, reg)

# visualise
reg.setWorld(worldLogical.name)
v = _vi.VtkViewerNew()
v.addLogicalVolume(reg.getWorldVolume())
v.buildPipelinesAppend()
v.view(interactive=True)

causes the kernel to die when

v.view(interactive=True)

is executed.

That might be an issue with visualisation libraries getting loaded though.

I thought I commented all the view lines out. I'll check
