我已经在Windows 10上安装了Jupyter Notebook。我可以执行 jupyter notebook 命令。它将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，我在右上角出现内核错误。单击它后，将出现此窗口：
无法启动内核
未处理的错误

我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。
我是编程新手，所以请尝试用简单的语言提供建议，详细描述每个步骤。
过去，我尝试删除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。但此错误保持不变。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。但也许问题是别的什么。
同样的问题在这里。对我有用的是作为管理员运行 Anaconda Navigator。希望它也适合您。
自上次更新jupyter_client以来，会出现此问题。 您可以通过降级到最新版本来暂时解决此问题。
conda install jupyter_client=5.3.1
