Jupyter Notebook/Lab未启动

Question

我在Jupyter Lab上看到白屏，在Jupyter Notebook上看到黑屏。无论是从命令行启动还是从导航器启动，都是一样的。

(base) C:\Users\Satish>jupyter lab
[I 17:21:33.289 LabApp] JupyterLab extension loaded from 
C:\ProgramData\Anaconda3\lib\site-packages\jupyterlab
[I 17:21:33.289 LabApp] JupyterLab application directory is

[I 17:21:33.289 LabApp] JupyterLab extension loaded from 
C:\ProgramData\Anaconda3\lib\site-packages\jupyterlab
[I 17:21:33.289 LabApp] JupyterLab application directory is 
C:\ProgramData\Anaconda3\share\jupyter\lab
[I 17:21:33.289 LabApp] Serving notebooks from local directory: C:\Users\Satish
[I 17:21:33.289 LabApp] The Jupyter Notebook is running at:
[I 17:21:33.289 LabApp] http://localhost:8888/? 
token=b270fb632dd40eecd4f2d4bf150476cc9eaa5b514a20ac04
[I 17:21:33.289 LabApp] Use Control-C to stop this server and shut down all kernels (twice to skip confirmation).
[C 17:21:33.351 LabApp]

To access the notebook, open this file in a browser:
    file:///C:/Users/Satish/AppData/Roaming/jupyter/runtime/nbserver-7396-open.html
Or copy and paste one of these URLs:
    http://localhost:8888/?token=b270fb632dd40eecd4f2d4bf150476cc9eaa5b514a20ac04

这开始发生在我pip安装jupytertheam之后，我删除了它并重新安装了conda，但是这个问题仍然存在。

Answer 1

我也面临着同样的问题。我为Windows10 python 3.6 anaconda环境降级了笔记本版本。

 pip uninstall notebook 
 pip install notebook==5.7.5

如果您仍然有问题。然后，以下链接可能会有所帮助：- https://github.com/jupyter/notebook/issues/4467

Answer 2

你说白屏还是黑屏是什么意思？在你的控制台中，jupyter似乎启动得很好。您是否访问了控制台中提到的url？

下面的解决方案是基于我个人的经验。我希望这能有所帮助(尽管我不确定你的问题是什么)：

复制http://localhost:8888而不是带有令牌的整个url，通常会有一个登录网页。如果没有，请尝试使用此命令重定向您的端口，很可能8888正在被占用: jupyter lab -- port =8889并在浏览器中尝试http://localhost:8889。

要在终端类型中下载：

pip install jupyter lab

要打开类型，请执行以下操作：

jupyter-lab

--如果你已经做过了，再做一次--
