I get an error when I use jupyter-notebook in vs-code with the newest python extension. After creating a new blank jyupter notebook with easy command every time I failed to launch jyupyter server. The error hint is 'Error: The Jupyter notebook server failed to launch in time [I 23:22:42.012 NotebookApp] The port 8888 is already in use, trying another port.' or 'jupyter notebook server failed to launch in time' and nothing displayed in the debug console.
What should I do?
