WSL安装Jupyter notebook需要注意的事项

WSL安装Jupyter notebook需要注意的事项

常规的Jupyter notebook安装可以参考网上很多资料，这里是由于我的是Windows linux子系统，所以有额外需要注意的东西。记录一下。

打不开浏览器、浏览器找不到文件
先生成config文件，终端输入

jupyter notebook  --generate-config

之后进入./jupyter，打开jupyter_notebook_config.py
输入以下四行，定义好自己要用的浏览器，比如我用的火狐，就这样加，其他浏览器相应地改名字就好了。

import webbrowser
webbrowser.register ('firefox',None,webbrowser.GenericBrowser('...浏览器路径（注意是反斜杠/）/firefox.exe'))
c.NotebookApp.open_browser = True 
c.NotebookApp.browser = 'firefox' 

上面这四行是添加了浏览器，其中后面两行可以直接搜索再对应的位置上更改就好。

接下来在jupyter_notebook_config.py中查找WSL：vim中直接输入/WSL，回车定位，可以找到如下解释：

## Disable launching browser by redirect file
#
#  For versions of notebook > 5.7.2, a security feature measure was added that
#  prevented the authentication token used to launch the browser from being
#  visible. This feature makes it difficult for other users on a multi-user
#  system from running code in your Jupyter session as you.
#
#  However, some environments (like Windows Subsystem for Linux (WSL) and
#  Chromebooks), launching a browser using a redirect file can lead the browser
#  failing to load.  This is because of the difference in file structures/paths
#  between the runtime and  the browser.
#
#  Disabling this setting to False will disable this behavior, allowing the
#  browser  to launch by using a URL and visible token (as before).
#c.NotebookApp.use_redirect_file = True
变成
c.NotebookApp.use_redirect_file = False

我们就按他说的办，把最后一行删掉#，把True改成False。这样浏览器就不会再出现找不到文件的问题了。

打开Jupyter notebook超时，一直等待响应

那有可能你和我的习惯一样，都是用像下面这样Ctrl+z来关闭Jupyter的，这样的话，继续启动就会一直等待响应。

正确关闭的方法是Ctrl+c：
