Question

因此，我尝试按照以下Google的说明将Google Colab链接到安装在Linux（ubuntu）计算机上的Jupyter笔记本电脑：https://research.google.com/colaboratory/local-runtimes.html

笔记本服务器启动正常，但通过Google Colab连接到笔记本服务器时，连接失败，出现了“禁止”错误。

(base) my_user@sysmain:~$ jupyter notebook --NotebookApp.allow_origin='https://colab.research.google.com' --port=8888 --NotebookApp.port_retries=0 --no-browser

以前（https://github.com/googlecolab/colabtools/issues/162）上已有关于此主题的文章，但是添加--no-browser并不能解决问题，如您所输入的命令所见。

感谢您的帮助！

Answer 1

我在 ~/.jupyter/jupyter_notebook_config.py 中配置 jupyter 进行密码验证后遇到了这个问题。注释掉这些行

c.NotebookApp.password
c.NotebookApp.password_required

关闭密码并导致 Jupyter 使用基于令牌的身份验证。或者，如果您添加这样的一行

c.NotebookApp.token = 'yourTokenValue'

然后你可以通过 http://localhost:PORT/?token=yourTokenValue 连接

注意您在 Google Colab 中复制到“本地连接设置”的网址。在本地运行 jupyter notebook 时，会打印如下输出：

[I 15:23:07.292 NotebookApp] Use Control-C to stop this server and shut down all kernels (twice to skip confirmation).
[C 15:23:07.296 NotebookApp]

    To access the notebook, open this file in a browser:
        file:///Users/<your-username>/Library/Jupyter/runtime/nbserver-56791-open.html
    Or copy and paste one of these URLs:
        http://localhost:8888/?token=xyz....xyz
     or http://127.0.0.1:8888/?token=xyz....xyz

您应该复制此处显示的“确切”网址，即：

http://localhost:8888/?token=xyz....xyz

实际上，这里的 token 负责身份验证，这样您就不会再收到 403。
