I am trying to show two plots vertically. I get an error message at show(column(west_fig, east_fig))

Could you please help me understand the error message?

Version: BokehJS 1.4.0 successfully loaded.

Note: I am running this code in Jupyter notebook

Error:

Make only one show statement at the end of your code. This implies deleting show(column(west_fig, east_fig)), show(west_fig), show(east_fig) lines and adding at the end of the code show(column(west_fig, east_fig))
