通过/etc/rc.local运行时，Jupyter Notebook无法找到内核 [英] Jupyter notebook can't find kernel when run through /etc/rc.local

问题描述

我在带有python2(默认)和ITorch内核的EC2实例上拥有Jupyter Notebook服务器.通过SSH命令行运行时，一切正常.

I have a Jupyter Notebook server on an EC2 instance with python2 (default) and ITorch kernels. Everything works fine when run through SSH command line.

问题是，当我尝试在启动时运行该笔记本时，笔记本服务器找不到ITorch内核.我确实可以在python笔记本上正常工作.我得到的错误是一个窗口说

The problem is that when I try to make this run at startup, the notebook server can't find ITorch kernel. I does work fine for python notebooks though. The error I get is a window saying

Kernel not found
I couldn't find a kernel matching iTorch. Please select a kernel: (python2)

我所做的就是将此行添加到/etc/rc.local

What I did was adding this line to /etc/rc.local

 /home/ubuntu/anaconda2/bin/jupyter-notebook --JupyterApp.config-file=/home/ubuntu/.jupyter/jupyter_notebook_config.py &> /dev/null &

笔记本服务器显然运行良好.这是来自系统日志

The notebook server apparently runs fine. This is from the system log

ip-172-31-20-152 login: [32m[I 12:20:51.073 NotebookApp][0;10m Serving notebooks from local directory: /home/ubuntu/notebook
[32m[I 12:20:51.076 NotebookApp][0;10m 0 active kernels 
[32m[I 12:20:51.078 NotebookApp][0;10m The Jupyter Notebook is running at: https://[all ip addresses on your system]:8888/
[32m[I 12:20:51.081 NotebookApp][0;10m Use Control-C to stop this server and shut down all kernels (twice to skip confirmation).

这些是我在配置文件中唯一修改过的行

These are the only lines I modified in my config file

# Configuration file for jupyter-notebook.
c = get_config()
c.NotebookApp.notebook_dir = u'/home/ubuntu/notebook'
c.NotebookApp.certfile = u'/home/ubuntu/certs/mycert.pem'
c.NotebookApp.keyfile = u'/home/ubuntu/certs/mycert.key'
c.NotebookApp.ip = '*'
c.NotebookApp.open_browser = False
c.NotebookApp.password = u'<password>'
c.NotebookApp.port = 8888

推荐答案

@Thomas K评论解决了它:

@Thomas K comment solved it:

"ITorch内核可能是为您的用户设置的，并且当系统运行它时，它是另一个用户.运行jupyter kernelspec list以查看内核的位置，如果ITorch在您的主目录下，则将其复制到/usr/local/share/jupyter/kernels/".

"The ITorch kernel is probably set up for your user, and when the system runs it, it's a different user. Run jupyter kernelspec list to see where the kernels are, and if ITorch is under your home directory, copy it to /usr/local/share/jupyter/kernels/".
