holoviews dynamicmap widgets don't show sliders

[rabernat]

Since our latest update on pangeo.pydata.org, holoviews dynamicmap widgets have been broken.

import holoviews as hv
import numpy as np
hv.extension('bokeh', width=100)

def fm_modulation(f_carrier=220, f_mod=220, mod_index=1, length=0.1, sampleRate=2000):
    sampleInc = 1.0/sampleRate
    x = np.arange(0,length, sampleInc)
    y = np.sin(2*np.pi*f_carrier*x + mod_index*np.sin(2*np.pi*f_mod*x))
    return hv.Curve((x, y), 'Time', 'Amplitude')

%%opts Curve [width=600]
f_carrier = np.linspace(20, 60, 3)
f_mod = np.linspace(20, 100, 5)

curve_dict = {(fc, fm): fm_modulation(fc, fm) for fc in f_carrier for fm in f_mod}

kdims = [hv.Dimension(('f_carrier', 'Carrier frequency'), default=40),
         hv.Dimension(('f_mod', 'Modulation frequency'), default=60)]
holomap = hv.HoloMap(curve_dict, kdims=kdims)
holomap

We are using holoviews version 1.10.7.

Any idea what is going on here?

I discovered almost by accident that I can drag on the area to the right of the text boxes and manipulate the slider. The slider itself is invisible however.

Also bokeh version 0.12.16

and inside jupyterlab.

Can't immediately reproduce, any chance you could also provide the JupyterLab and jupyterlab_pyviz JLab extension versions?

[rabernat]

Jupyterlab version is '0.34.2'. @pyviz/jupyterlab_pyviz v0.6.1

Thanks, I'll try to reproduce the exact setup.
