长时间运行的Jupyter笔记本/实验室? [英] Long running Jupyter notebook/lab?

问题描述

我让Jupyter在ec2实例的tmux会话中运行.我的单元格运行时间很长，但是当我关闭浏览器或笔记本电脑盖时，笔记本电脑不再写入输出单元格(并且可能使python内核崩溃).

I have Jupyter running in a tmux session on an ec2 instance. I have very long-running cells, but when I close my browser or laptop lid, the notebook no longer writes output cells (and may crash the python kernel).

这是我在远程实例上启动实验的方式:

This is how I launch labs on my remote instance:

jupyter lab --ip=0.0.0.0 --port=5002 --no-browser --allow-root

我正在寻找一种解决方案，可以无限期运行笔记本电脑而不会丢失数据，而不必保持本地计算机的电源.

I'm looking for a solution to run a notebook indefinitely without losing data and without having to keep my local computer on.

• 我不想使用VNC或X-windows转发(太慢)
• 我不想将我的代码重写为python脚本(仅在jupyter实验室中需要工作)

那里必须有一个解决方案！

There has got to be a solution out there!

更新:

以下"nohup"解决方案不起作用:

The 'nohup' solution below doesn't work:

运行此单元格并关闭浏览器后，重新打开后将没有输出:

After running this cell and closing the browser, upon reopening there is no output:

推荐答案

编辑(在澄清之后):

关闭浏览器或笔记本电脑后，您可以使用Jupyter魔术来继续运行单元，然后在返回后打印输出.这是完成的方式:

You can use some Jupyter magic to continue running the cell after you close the browser or laptop, and then print the output after you return. Here's how that's done:

%%capture stored_output

import time
time.sleep(30)
print("Hi")

返回后，运行以下命令:

After returning, run the following:

stored_output.show()
# Hi

原始:

您需要使用nohup启动笔记本电脑.

You need to launch the notebook with nohup.

nohup jupyter notebook &

添加&"只需要返回外壳.笔记本将在后台运行，并且在关闭SSH连接时不会杀死其进程ID.

Adding the '&' is only needed to return the shell. The notebook will be running in the background and it's process ID won't be killed when you close your SSH connection.
