Passing websocket_max_message_size when embedding bokeh server in a notebook

Community Support
1

When bokeh server is embedded in a notebook (like here bokeh/notebook_embed.ipynb at branch-3.0 · bokeh/bokeh · GitHub) there are connection errors when plots are large, like in this issue: Connection errors when sending large amounts of data to browser via a bokeh server · Issue #7374 · bokeh/bokeh · GitHub (and smaller plots work just fine). I see from the docs I can use --websocket-max-message-size argument with larger value for standalone bokeh server.

I wonder is there a possibility to use such argument when embedding bokeh server in a notebook, or maybe there is at least some workaround?

Hi,

All the command line arguments are also keyword parameters, e.g. websocket_max_message_size

Thanks,

Bryan

Hi Bryan,

I’ve noticed that the websocket_max_message_size is a keyword argument for Server class, but I wonder how to pass it that Server class from notebook when using bokeh.io.show(app, notebook_url).

I’ve checked Bokeh sources, it looks like this line is where the Server is created:

https://github.com/bokeh/bokeh/blob/d260c429451a04b1fc00f593ef98f10ce1392e57/bokeh/io/notebook.py#L475

and no **kwargs are passed to it from the outer function. Looks like there is no straightforward way to pass websocket_max_message_size to the created server.

Hi,

I think for now you will have to make your own version of the show_app function that passes the parameter. If you wanted to make PR that makes things more user-configurable, e.g. add a generic **kwargs parameter to show_app that gets passed on to Server, we would certainly consider it.

Thanks,

Bryan

Hi Bryan,

Yes, I’ll try to make a PR that does that. The corresponding issue is Make websocket_max_message_size configurable in notebooks · Issue #8583 · bokeh/bokeh · GitHub

Best,

Eugene
