我正在使用 jupyter notebook，ipython 3 on windows。每当我启动 python 3 时，我都会收到 "Kernel Dead" 消息

Question

死内核内核死了，自动重启失败。内核可能无法重新启动。如果您无法重新启动内核，您仍然可以保存笔记本，但是运行代码将不再工作，直到笔记本重新打开。

以上消息在我启动 python3 后显示在笔记本仪表板中。

在命令提示符下，我收到如上所示的消息。 faulthandler 模块中的问题是什么。我应该如何纠正它？我使用 "pip" 安装了 jupyter notebook。我是 python 编程的新手，也是 jupyter 的新手。请帮我解决这个问题。

Answer 1

我们不小心发布了 ipykernel 软件包，它在 Windows 上的 Python 3.5 上不起作用。意识到这一点后，我们发布了一个新版本（版本 4.3.1）来修复它。

您可以通过运行升级：

pip install --upgrade ipykernel

如果您使用 conda 安装了 ipykernel，则命令为：

conda update ipykernel
