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“Kernel Dead”。信息 [英] I am using jupyter notebook, ipython 3 on windows. Whenever i am starting my python 3, i get the "Kernel Dead" message

问题描述

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。

Dead kernel The kernel has died, and the automatic restart has failed. It is possible the kernel cannot be restarted. If you are not able to restart the kernel, you will still be able to save the notebook, but running code will no longer work until the notebook is reopened.

启动python3后，上面的消息显示在笔记本仪表板中。

the above message is shown in notebook dashboard after i start python3.

在命令提示符下，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？我用pip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。

In command prompt i get the above shown message. What is the problem in the faulthandler module. How should I rectify it? I installed jupyter notebook by using "pip". I am new to python programming and also jupyter. please help me resolve this.

推荐答案

我们不小心发布了 ipykernel 包在Windows上使用Python 3.5。一旦我们意识到这一点，我们制作了一个新版本（版本4.3.1）来修复它。

We accidentally made a release of the ipykernel package which doesn't work on Python 3.5 on Windows. Once we realised this, we made a new release (version 4.3.1) to fix it.

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：

If you had installed ipykernel using conda, the command would be:

conda update ipykernel
