在 VS Code 中无法启动 Jupyter Notebook 中的内核

Question

我尝试在 M1 MacBook Air 的 VS Code 中运行笔记本。但最终出现此错误：

Failed to start the Kernel. 
Traceback (most recent call last):
  File "/Users/akshitdudeja/.vscode/extensions/ms-toolsai.jupyter-2022.6.1201981810/pythonFiles/vscode_datascience_helpers/jupyter_daemon.py", line 158, in _start_notebook
    from notebook import notebookapp as app

    raise ImportError(_("The Jupyter Notebook requires tornado >= 5.0, but you have %s") % tornado.version)
ImportError: The Jupyter Notebook requires tornado >= 5.0, but you have 4.5.3

During handling of the above exception, another exception occurred:

1. 尝试使用以下命令更新 jupyter：

   pip install -U jupyter

ImportError(("Jupyter Notebook 需要 tornado >= 5.0，但你有 %s") % tornado.version)

您可以尝试以下方法来升级龙卷风

pip install tornado --upgrade
