Bokeh Port Error

[koaning]

Sometimes I hit this error:

ERROR:bokeh.server.views.ws:Refusing websocket connection from Origin 'http://localhost:8889';                       use --allow-websocket-origin=localhost:8889 or set BOKEH_ALLOW_WS_ORIGIN=localhost:8889 to permit this; currently we allow origins {'localhost:8888'}
WARNING:tornado.access:403 GET /ws (::1) 1.65ms

Would be nice to get an automated fix for this.

This is related to something
bokeh cannot do without explicit permission from jupyter. It can't be fixed by this library but I added something to the FAQ to explain.

Hi,
Spent quite some time on this issue. Couldn't get around displaying the charts in in VSC notebooks as per ##67
Exporting the variable in ~/.bashrc didn't work either for me for some reason.
When encountering this issue, I solved it by running jupyter lab instead and explicitly setting

import os os.environ["BOKEH_ALLOW_WS_ORIGIN"] = "localhost:8889"

And then running
charts = InteractiveCharts(df.loc[lambda d: d['label'] == ''], labels = ['group']) charts.add_chart(x = "dim1", y = "dim2")
normally, as Vincent does in PyData Riyadh

Hope this helps

@koaning, perhaps we can add this (quite hacky) fix to the examples/fag?
