我需要有关 jupyter notebook 内核启动的帮助。它一直工作到一天前，在我被困在“内核启动，请稍候”之后。我不确定应该从哪里开始，关于这个主题的内容不多。
版本：
python: 3.8.7
Jupyter: 1.0.0
tornado: 6.1
jupyter-packaging 0.7.12
jupyter_client 6.1.12
jupyter_console 6.4.0
jupyter_core 4.7.1
jupyter_server 1.4.1
jupyterlab 3.0.14
jupyterlab_pygments 0.1.2
jupyterlab_server 2.4.0
jupyterlab_widgets 1.0.0
在我的 macbook 终端中，这是我看到的：
