Bokeh example: weather plot cannot update in Jupyter notebook

Community Support
1

Hello,

New to Bokeh. I tried to run Bokeh example: bokeh/examples/app/weather at branch-3.0 · bokeh/bokeh · GitHub using Jupyter notebook. I added few lines related to notebook

from bokeh.io import curdoc, output_notebook, push_notebook

from bokeh.plotting import figure, show

output_notebook()

and

handle = show(row(plot, controls),notebook_handle=True)

push_notebook(handle=handle)

Everything works fine, but the plot does not update when I click the graphic column to change Austin to Boston.

I am not sure where the function : update_plot, is being called to update. Any help will be appreciated.

Thanks,

Wanli Wu

That example is a bokeh server example. It has to be run using a Bokeh server (that is where the callbacks actually get executed). E.g. by executing

  bokeh serve --show weather

in a command shell It will not work as-is in the notebook. There is a preliminary, proof-of-concept for embedding Bokeh server apps in notebooks here:

  https://github.com/bokeh/bokeh/blob/master/examples/howto/server_embed/notebook_embed.ipynb

That approach does have issues (described in the notebook). A full robust and supported solution for embedding Bokeh apps in notebooks will be in the 0.12.5 release.

Thanks,

Bryan

Bryan,

Thank you very much. It’s good to know the current issue in notebook, and look forward to the next release of Bokeh. – Wanli
