To access the notebook, open this file in a browser:
    file:///C:/Users/Dell/AppData/Roaming/jupyter/runtime/nbserver-20672-open.html
Or copy and paste one of these URLs:
    http://localhost:8888/?token=8ee269226240ce7b5a7c580664ade26546bb7e0691775535
 or http://127.0.0.1:8888/?token=8ee269226240ce7b5a7c580664ade26546bb7e0691775535

我认为使用水蟒可能有助于摆脱困境。但是每次我运行anaconda导航器时，它都会崩溃。然后我尝试通过conda提示符运行anaconda 而且我看到它对Jupyter plus spyder也不起作用，并且存在相同的问题。我想ipykernel出了点问题。

我无法启动Jupyter Notebook
