Jupyter笔记本 - 死亡内核

python-3.xjupyter-notebook
13

我正尝试使用Jupyter Notebook，但打开文件时出现以下错误：

内核已停止运行，并且自动重启失败。可能无法重新启动内核。如果您无法重新启动内核，则仍然可以保存笔记本，但在重新打开笔记本之前无法运行代码。

在CMD中，我看到以下内容：

我尝试卸载并重新安装了一些模块，但是无法解决问题。有什么想法吗？谢谢！

看起来jupyter的安装出了点问题。我建议将anaconda升级到v5，这样应该会默认安装jupyter(不确定在这种情况下是否适用于v3)。如果您想继续使用conda v3，则可以尝试使用conda install安装缺少的模块。

conda install -c conda-forge jupyterlab
conda install -c anaconda ipython

IPython, Jupyterlab

这对我很有帮助，因为我正在尝试在Jupyter Notebook中运行ArcGIS Python API，安装了这两个包后出现了此错误。我只收到了这个警告：Matplotlib正在构建字体缓存；可能需要一段时间。 - Abdur Rahman

我遇到了同样的错误。这是因为我们没有给予管理员权限。您需要使用管理员权限安装Anaconda，或以管理员身份运行应用程序。只需右键单击Jupyter或Spyder，然后选择以管理员身份运行。或在安装Anaconda时选择以管理员身份安装。

我尝试了不同的方法来解决这个问题，但是都没有成功，最后通过重新安装jupyter解决了。
打开你的anaconda控制台并运行以下命令。
要在anaconda上安装Jupyter笔记本，请输入： pip install jupyterlab
要从anaconda上运行Jupyter，只需输入 jupyter-lab
现在，你将能够通过新的jupyter解决内核死机问题。
