在Azure深度学习虚拟机上无法访问Jupyter Notebook [英] Can't reach Jupyter Notebooks on Azure Deep Learning Virtual Machine
问题描述
我遵循了此处.
我通过SSH在Ubuntu VM上. 我尝试访问IP:8000,但Chrome浏览器显示无法访问该网站.如文档中所述,默认情况下,端口8000确实是开放的.
I am on the Ubuntu VM via SSH. I tried to access IP:8000 but Chrome says the Site can't be reached. Port 8000 is indeed open by default as mentioned in the docs.
指令没有提及是否必须启动jupyterhub
,所以我尝试了此操作并收到了此错误-
Instructions don't mention if I have to start jupyterhub
so I tried that and got this error -
username@fastai:~ $ jupyterhub

在文档中阅读有关jupyterhub的内容之前,我尝试启动jupyter notebook
,这给了我这个错误.
Before I read about jupyterhub in the docs, I tried starting jupyter notebook
which gave me this error.
[C 04:00:12.963 NotebookApp] Bad config encountered during initialization:
[C 04:00:12.963 NotebookApp] No such notebook dir: ''/dsvm/Notebooks''
使用jupyter notebook --generate-config
生成配置文件并对其进行编辑后,它似乎运行良好,但是尽管打开了所有端口,但我仍然无法通过Chrome访问它.
It seemed to run fine after generating a config file using jupyter notebook --generate-config
and editing it but I still couldn't reach it via Chrome despite opening up all ports.
更新
今天,我安装了X2Go客户端,并找到了桌面上的jupyter笔记本图标,但启动后抛出此错误-
无法运行Jupyter.desktop
无法解析桌面文件:密钥文件包含'/anaconda/pkgs/notebook-5.4.0-py27_0/info/icon.png'行,该行不是键值对,组或注释
UPDATE
Today I installed an X2Go client and found the jupyter notebook icon on the desktop but starting that threw this error -
Failed to run Jupyter.desktop
Failed to parse the desktop file: Key file contains line '/anaconda/pkgs/notebook-5.4.0-py27_0/info/icon.png' which is not a key-value pair, group, or comment
看起来该文件调用了jupyter notebook,它引发了与以前相同的错误.
Looks like that file calls jupyter notebook which throws the same error as before.
推荐答案
这是由一个漏洞引起的,此漏洞已在更高版本的深度学习VM中修复.
This was caused by a bug which has since been fixed on the later versions of the Deep learning VM.
