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:

Я думал, что использование анаконды может помочь избавиться. но каждый раз, когда я запускаю Anaconda Navigator, происходит сбой. Затем я попытался запустить anaconda через приглашение conda, и то, что я вижу, также не сработало для Jupyter, и у spyder возникла та же проблема. Я думаю, что-то не так с ipykernel.
