在jupyter笔记本的单元格内使用sudo

问题描述：

我正在尝试为Jupyter笔记本中的平台制作教程

I'm trying to make a tutorial for a platform inside a jupyter notebook

有时候，我需要在像这样的单元中运行linux命令:

at some point I need to run a linux command inside a cell like this :

!sudo apt-get install blah

但是无法弄清楚如何输入sudo通行证，并且我不想用sudo运行jupyter笔记本，知道如何执行此操作吗?

but cant figure out how to enter the sudo pass , and I dont want to run jupyter notebook with sudo, any idea how to do this ?

答

更新:我检查了所有方法，所有方法都有效.

Update: I checked all the methods, all of them are working.

请求密码，这实际上隐藏了用户的输入，然后运行 python中的sudo命令.

Request password using getpass module which essentially hides input by user and then run sudo command in python.

 import getpass
 import os

 password = getpass.getpass()
 command = "sudo -S apt-get update" #can be any command but don't forget -S as it enables input from stdin
 os.system('echo %s | %s' % (password, command))

 import getpass
 import os

 password = getpass.getpass()
 command = "sudo -S apt-get update" # can be any command but don't forget -S as it enables input from stdin
 os.popen(command, 'w').write(password+'\n') # newline char is important otherwise prompt will wait for you to manually perform newline

注意上述方法:

您输入密码的字段可能不会出现在ipython中笔记本.它出现在Mac的终端窗口中，我想像它将出现在PC的命令外壳中.甚至结果详细信息也将出现在终端中.

The field where you enter the password may not appear in the ipython notebook. It appears in the terminal window on a mac, and I imagine it will appear in a command shell on a PC. Even the result details would appear in the terminal.

您可以将密码存储在mypasswordfile文件中，只需输入单元格即可:

You can store your password in mypasswordfile file and just type in cell :

!sudo -S apt-get install blah < /pathto/mypasswordfile # again -S is important here

如果我想在jupyter notebook本身中查看命令的输出，我会更喜欢这种方法.

I would prefer this method if I want to view output of the command in jupyter notebook itself.
