如何在Jupyter Notebook中设置环境变量

问题描述

我有一个问题，Jupyter在bashrc文件中看不到env变量，有没有办法在jupyter中加载这些变量或向其中添加自定义变量?

I've a problem that Jupyter can't see env variable in bashrc file, is there a way to load these variables in jupyter or add custome variable to it?

推荐答案

要在jupyter笔记本中设置环境变量，只需使用%魔术命令，例如%env或%set_env，例如%env MY_VAR=MY_VALUE或%env MY_VAR MY_VALUE. (单独使用%env可以打印出当前的环境变量.)

To set an env variable in a jupyter notebook, just use a % magic commands, either %env or %set_env, e.g., %env MY_VAR=MY_VALUE or %env MY_VAR MY_VALUE. (Use %env by itself to print out current environmental variables.)
