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

文件中的代码不会以不同的颜色突出显示，运行时什么也没发生.

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

我是编程的新手，所以请尝试以简单的语言给出建议，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，我曾尝试删除Python，安装其他版本的Python，然后安装Anaconda.另外，为了使用tensorflow，我创建了一个特殊的环境.但是此错误保持不变.我怀疑问题是路径中的双反斜杠("//")，但我绝对不知道如何解决此问题.但是也许问题出在其他地方.

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

此处存在完全相同的问题.对我有用的是以管理员身份运行Anaconda Navigator.希望它也对您有用.

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