启动jupyter笔记本时内核死了

Question

我已经安装了Python 3.6和Anaconda 3.安装成功但是，当我启动笔记本时，立即出现内核错误，并出现以下错误消息：

FileNotFoundError: [WinError 2] Le fichier spécifié est introuvable 

请注意，在安装Anaconda 3之前，我卸载了Anaconda 2（使用Python 2.7）。

我怎样才能解决这个问题？

Answer 1

最后我在网上找到了一个解决方案：

我必须执行以下命令：

 python -m ipykernel install --user
