有没有办法检测笔记本显示在 voila、jupyter 或 jupyterlab 中？

Question

I'm using the xarray_leaflet library that has has a different behavior if the notebook is launch with voila, jupyter or jupyterLab.

Is there a way to detect it programmatically ?

Answer 1

In versions of voila > .2 , there are a bunch of environmental variables on the running environment (eg 'QUERY_STRING', 'SERVER_SOFTWARE', 'SERVER_PROTOCOL', 'SERVER_PORT', 'PATH_INFO', 'SERVER_NAME', 'SCRIPT_NAME' ), so detecting if you are running in voila is as simple as checking if any of those exist, or even better:

import os
running_in_voila = os.environ.get('SERVER_SOFTWARE','jupyter').startswith('voila')
