在 Google Cloud VM 上运行 Jupyter Notebook 时出现 SSL 错误

Question

我已经在GCP虚拟机上设置了一个实例，并安装了anaconda，torch等，并初始化了我的Jupyter笔记本(包括配置设置(。我已经安装了我的谷歌存储桶，一切似乎都很好，除了当我运行Jupyter时：

~$ jupyter notebook --certfile=/home/username/certs/mycert.pem
[I 16:18:41.293 NotebookApp] [nb_conda_kernels] enabled, 3 kernels found
[I 16:18:44.879 NotebookApp] Serving notebooks from local directory: 
/home/username
[I 16:18:44.879 NotebookApp] 0 active kernels 
[I 16:18:44.879 NotebookApp] The Jupyter Notebook is running at: 
https://0.0.0.0:8888/
[I 16:18:44.879 NotebookApp] Use Control-C to stop this server and shut 
down all kernels (twice to skip confirmation).

我可以在 VM 的外部 IP 上访问它：

https://xx.xxx.xxx.xx:8888

但是一旦我这样做，我就会收到此错误：

ssl.SSLError: [SSL: SSLV3_ALERT_CERTIFICATE_UNKNOWN] sslv3 alert 
certificate unknown (_ssl.c:645)

完整回溯：

这是在 Linux VM 上。在本地，我在电脑上。我已经尝试重写 Jupyter 的配置文件，但我遇到了这个问题。我在网上找到的解决方案都没有奏效。

您似乎正在尝试使用 Jupyter 手动设置 VM 实例。这往往非常棘手，您是否考虑过使用 GCP 的 AI 平台笔记本？https://cloud.google.com/ai-platform-notebooks

它为您提供了一个带有Jupyter Lab和许多预安装和配置的流行DL/ML库的VM，您甚至不需要SSH即可访问笔记本。
