无法打开给定的 URL 来访问在 GCP VM 中运行的 Jupiter 笔记本

Question

我在 python GCP VM 中运行 ML 模型，结果（可视化）存储在 jupyter 笔记本中。因此，我将 jupyter 笔记本安装到 ubuntu 虚拟机，并使用

jupyter notebook --ip=0.0.0.0 --port=8888 --no-browser

命令从相关位置运行 jupyter。它给出了这个输出

Read the migration plan to Notebook 7 to learn about the new features and the actions to take if you are using extensions.

https://jupyter-notebook.readthedocs.io/en/latest/migrate_to_notebook7.html

Please note that updating to Notebook 7 might break some of your extensions.

[I 14:16:46.732 NotebookApp] Registered dataproc_jupyter_plugin server extension

[C 14:16:47.328 NotebookApp] You must use Jupyter Server v1 to load JupyterLab as notebook extension. You have v2.12.5 installed.
    You can fix this by executing:

    To access the notebook, open this file in a browser:
        file:///path_to_jupyter_runtime/nbserver-684890-open.html
    Or copy and paste one of these URLs:
        http://base_url:8888/?token=token_value
     or http://#.#.#.#:8888/?token=token_value

无论如何，当我尝试访问给定的链接时：

http://base_url:8888/?token=token_value
     or http://#.#.#.#:8888/?token=token_value

jupytor 笔记本未加载，浏览器显示无法访问该页面

我做了两件事

1. 我通过以下方式在 VPC 网络 > 防火墙规则中添加了防火墙策略：

• 单击“创建防火墙规则”。
• 设置以下内容：
• 名称：Allow-Jupyter
• 目标：网络中的所有实例
• 源 IP 范围：0.0.0.0/0
• 允许的协议和端口：tcp:8888
• 点击“创建”。

2. 在VM中我遵循了here中提到的内容 为我想要运行 jupyter 的端口添加防火墙规则（例如 8888）

   jupyter notebook --generate-config

   确保使用

    在位置 

   jupyter_notebook_config.py

    生成 

   /.jupyter/jupyter_notebook_config.py
文件

sudo vi /home/user_name/.jupyter/jupyter_notebook_config.py

在 vi 编辑器中添加了以下几行

c.NotebookApp.ip = '*'

c.NotebookApp.open_browser = False

c.NotebookApp.port = 8888

通过 esc + :wq 命令退出 vi 编辑器

然后运行相同的命令

jupyter notebook --ip=0.0.0.0 --port=8888 --no-browser

没有什么新的，相同的结果 我错过了什么

Answer 1

尝试访问 Jupyter Notebook 时，将 URL 中的 base_url 和 token_value 替换为实际值。 base_url应该是您虚拟机的外部IP，token_value是启动Jupyter笔记本时生成的令牌。
