尝试在CentOS 7上运行jupyter notebook。返回结果为：

OSError: [Errno 99] Cannot assign requested address

和堆栈跟踪：

[user@desktop ~]$ jupyter notebook
Traceback (most recent call last):
  File "/home/use/anaconda3/bin/jupyter-notebook", line 6, in <module>
    sys.exit(notebook.notebookapp.main())
  File "/home/user/anaconda3/lib/python3.6/site-packages/jupyter_core/application.py", line 267, in launch_instance
    return super(JupyterApp, cls).launch_instance(argv=argv,**kwargs)
  File "/home/user/anaconda3/lib/python3.6/site-packages/traitlets/config/application.py", line 657, in launch_instance
    app.initialize(argv)

jupyter notebook --ip=127.0.0.1 --port=8888

我不得不简单地设置IP/端口参数。这个问题很可能是因为它以前试图分配的默认IP/端口已经被占用了！

在远程虚拟机中，我通过以下方法解决了该问题

$ jupyter-notebook --ip=0.0.0.0 --port=8888
...

    Copy/paste this URL into your browser when you connect for the first time,
    to login with a token:
        http://0.0.0.0:8888/?token=1234567890abcdefghijklmnopqrstuvwxyz  (the token is for demo)

...

注意：不要指定特定的ip
然后我可以通过以下方式连接到Jupyter笔记本电脑：

http://your_vm_ip:8888/?token=1234567890abcdefghijklmnopqrstuvwxyz

（将0.0.0.0替换为your_vm_ip）

这里有一个永久的解决办法。
1.为Jupyter创建一个配置文件，在终端中输入：jupyter notebook --generate-config
1.最后一个命令将在**/home/USER/.jupyter/jupyter_notebook_config.py中创建文件
1.打开文件jupyter_notebook_config.py并编辑变量c.NotebookApp.ip**，如下所示：
# c.NotebookApp.ip = 'localhost'个
c.NotebookApp.ip = '127.0.0.1'
1.在终端中输入：jupyter notebook
