当 运行 通过 /etc/rc.local 时，Jupyter notebook 找不到内核
Jupyter notebook can't find kernel when run through /etc/rc.local
我在具有 python2（默认）和 ITorch 内核的 EC2 实例上有一个 Jupyter Notebook 服务器。 运行 通过 SSH 命令行一切正常。
问题是当我在启动时尝试运行，notebook 服务器找不到ITorch 内核。不过，我在 python 笔记本电脑上工作得很好。我得到的错误是 window 说
Kernel not found
I couldn't find a kernel matching iTorch. Please select a kernel: (python2)
我所做的是将这一行添加到 /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 没问题。这是来自系统日志

[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修改的唯一几行
# 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.port = 8888

"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/".
