ALL software version info

Python: 3.9

Failing versions:

Description of expected behavior and the observed behavior

bokeh plots aren’t working in jupyter notebook without an internet connection due to new dependencies on cdn delivered assets

Complete, minimal, self-contained example code that reproduces the issue

In a jupyter notebook in a browser without internet access. Easiest way to get it it to start firefox as follows (linux):

$ env http_proxy=http://localhost:1/ https_proxy=http://localhost:1/ firefox --profile nointernet

# notebook code
import pandas as pd
df = pd.DataFrame({'a':range(10),'b':range(10,20)})
import bokeh
import holoviews as hv
import panel as pn
print(bokeh.__version__, hv.__version__, pn.__version__)
hv.extension('bokeh', inline=True)
display(hv.Scatter(df))

Stack traceback and/or browser JavaScript console output

Edit: Just to add using bokeh plotting directly via output_notebook(INLINE) works fine offline.

I’ll resolve this before the Panel 0.14 release tomorrow.

Ignore my previous comment, panel.layout.gridstack is imported by default.
