推荐答案

在voila版本中> .2 ，正在运行的环境上有一堆环境变量(例如，'QUERY_STRING'，'SERVER_SOFTWARE'，'SERVER_PROTOCOL'，'SERVER_PORT'，'PATH_INFO'，'SERVER_NAME'，'SCRIPT_NAME')，因此检测您是否在voila中运行就像检查其中是否存在一样简单，甚至更好:

In versions of voila > .2, there are a bunch of environmental variables on the running environment (e.g. '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')
