holoviews (fresh) jupyterlab extension problem

not sure if it’s me or holoviews:

• this type of example doesn’t seem work (yet) in Jupyterlab:

# Holoviews
# for more example, see http://holoviews.org/Tutorials/index.html
import numpy as np
import holoviews as hv
hv.extension('matplotlib')
dots = np.linspace(-0.45, 0.45, 11)
fractal = hv.Image(image)

layouts = {y: (fractal * hv.Points(fractal.sample([(i,y) for i in dots])) +
               fractal.sample(y=y) )
            for y in np.linspace(0, 0.45,11)}

hv.HoloMap(layouts, kdims=['Y']).collate().cols(2)

giving:

but the ultra-tricky one … does ???
