Bokeh: Models must belong to only one document.

Question

I work with Bokeh 0.12.2 in Jupyter notepad and it often throws exceptions that “Models should belong to only one document”:

---------------------------------------------------------------------------

---> 91             raise RuntimeError("Models must be owned by only a single document, %r is already in a doc" % (self))
     92         doc.theme.apply_to_model(self)
     93         self._document = doc

RuntimeError: Models must be owned by only a single document, <bokeh.models.tickers.DaysTicker object at 0x00000000042540B8> is already in a doc

A trigger always calls show(...)(although never after the first kernel launch, only subsequent calls).

Based on the docs, I thought I would reset_output()put my notebook back in working condition, but the exception persists. Through trial and error, I decided that it was also necessary to redefine everything that was passed in show(). This makes interactive work cumbersome and error prone.

reset_output (state = no)

Clear the default state of all output modes.
