I am trying to import Scatter from bkcharts and it fails with the following error:
ImportError: Traceback (most recent call last)

I am one of the maintainers of Bokeh. You should know (as stated prominently on the project GitHub page) that bkcharts is no longer part of core Bokeh, and more importantly, that it is completely unmaintained at this point. There is no future work, fixes, or effort planned to put into it, unless someone new decides to take ownership of it. If you must use bkcharts, my only suggestion is to not update Bokeh past 0.12.6, which is the last version that received any testing together.
However, my real advice is simply not to use bkcharts at all, for any reason, at this point. It's hard to know exactly what you are after with such a short code snippet, but I will say that all sorts of scatter plots are easy with core bokeh.plotting, and if you are after an even higher level interface then Holoviews is an officially endorsed higher level API built on top of Bokeh, that has an active development team working on it.
