python - 无法使用来自 Google Cloud 的 Jupyter Notebook 连接到 Google Colab

Question

我正在尝试从谷歌云转发并打开一个 jupyter 笔记本服务器以在本地运行时连接到谷歌云。但是，尽管进行了一些更改，但我始终无法连接到它。作为参考，我已经降级了 tornado，更新了 ipynb，并尝试了 jupyter notebook 命令行的几种变体。我一直将端口转发基于此链接：https ://research.google.com/colaboratory/local-runtimes.html 。有没有人知道如何帮助我连接它？当我尝试连接到 google colab notebook 中的本地运行时时，我在下面列出了错误代码。
