Question

死内核内核已经死亡，自动重启失败。内核无法重新启动。如果您无法重新启动内核，您仍然可以保存笔记本，但在重新打开笔记本之前，运行代码将不再有效。

启动python3后，上面的消息显示在笔记本仪表板中。

在命令提示符中，我收到上面显示的消息。 faulthandler模块中有什么问题。我该如何纠正呢？我使用＆＃34; pip＆＃34;安装了jupyter笔记本。我是python编程的新手，也是jupyter。请帮我解决这个问题。

Answer 1

我们意外地发布了ipykernel软件包，该软件包在Windows上不适用于Python 3.5。一旦我们意识到这一点，我们就制作了一个新版本（版本4.3.1）来修复它。

您可以通过运行升级来升级：

pip install --upgrade ipykernel

如果您使用conda安装了ipykernel，则命令为：

conda update ipykernel

我在Windows上使用jupyter笔记本，ipython 3。每当我开始我的python 3时，我都会得到＆＃34; Kernel Dead＆＃34;信息
