问题描述

我已经在 Windows 10 上安装了 Jupyter Notebook.我可以执行 jupyter notebook 命令.它打开并显示当前路径目录的列表.我还可以创建或打开笔记本.但是当我这样做时，我在右上角收到内核错误.点击后会出现这个窗口:

I have installed Jupyter Notebook on Windows 10. I can execute jupyter notebook command. It opens and shows a list of current path directories. I also can create or open a notebook. But when I do it I get Kernel error in the top right corner. After clicking on it this window appears:

无法启动内核

我的文件中的代码没有以不同的颜色突出显示，当我运行它时没有任何反应.

The code in my file is not highlighted in different colors and when I run it nothing happens.

我是编程新手，所以请尽量用简单的话给出建议，详细描述每个步骤.

I am new to programming, so please try to give advice in simple words, describing each step in detail.

过去，我尝试过删除Python，安装不同版本的Python，安装Anaconda.此外，为了使用 tensorflow，我创建了一个特殊的环境.但是这个错误保持不变.我怀疑问题是路径中的双反斜杠(//")，但我完全不知道如何解决这个问题.但也许问题出在别的地方.

In the past, I've tried to delete Python, install Python in different versions, install Anaconda. In addition, in order to work with tensorflow, I've created a special environment. But this error stays the same. I suspect the problem is a double backslash ("//") in the path, but I have absolutely no idea how to fix this. But perhaps the problem is something else.

推荐答案

同样的问题.对我有用的是以管理员身份运行 Anaconda Navigator.希望它也适用于您.

Same exact problem here. What worked for me was running the Anaconda Navigator as an Administrator. Hope it works for you too.
