Description of expected behavior and the observed behavior
Loading the bokeh extension in a notebook fails for bokeh version 2.0, which is now the default version for a clean conda installation. I installed the environment with the command
conda create -n holoviews python=3.7 holoviews jupyterlab
Complete, minimal, self-contained example code that reproduces the issue
import holoviews as hv
hv.extension('bokeh')
Stack traceback and/or browser JavaScript console output
WARNING:param.notebook_extension: Holoviews bokeh extension could not be imported, it raised the following exception: ModuleNotFoundError('No module named 'bokeh.plotting.helpers'')

I’ve already closed a few of these issues since this has been fixed on master but I’ll keep it open so we don’t get more issues like this. To be clear the only release blockers right now are:
I desperately need to get the HoloViews 1.13.0 out in the coming days. Almost back home after escaping Spain due to COVID19 so there’s a decent chance self-quarantine will speed it up. 😉
