I see. I personally do not use bokeh in that way so cannot offer personal experience on how to resolve.
That said, I was led to that GitHub issue from the following post on bokeh discourse. The author indicates that manifestation of the issue is strongly dependent on the order of imports, and they were successfully unblocked by some one-line change.
Not certain if that was tailoring the import order or something else; given the recentness of the post perhaps you might have luck getting them to elaborate on that fix.
