ThickTube : AttributeError: 'PolyData' object has no attribute 'dataset'

[SimonRelu]

When I run the example provided here: https://vedo.embl.es/docs/vedo/shapes.html#ThickTube I get the following error:

Traceback (most recent call last):
  File "test.py", line 4, in <module>
    thick_tube = ThickTube(vline, r1=0.2, r2=0.3).lw(1)
