报错及解决：Kernel does not exist: 96b59d42-d81e-471c-8ef9-63a61a963a16

在pycharm的terminal终端中，首次启动jupyter notebook，成功。中断之后重启，运行cell的时候找不到kernels，系统报错如下

(topvenv)..../feature190919>jupyter notebook

解决方案：
找到这个runtime目录，全部清空，重启jupyter就可以了

下面是我对这个错误的分析和解决思路
我直接把token的参数填了密码导致了本次错误

观察该目录，一启动jupyter notebook就生成了这三个文件

用记事本打开nbserver-2280.json文件，会发现123456并没有进入到password字段中，而是被放入到了token字段。这个时候在pycharm中点击

这时候会重新提示输入密码
输入密码之后保存就对了。
