jupyter lab 显示no kernel

Jupyter Lab显示no kernel

尝试了晚上的很多方法都不行,发现最简单的方法是jupyter相关的包全都卸载重装

查看jupyter相关的包

pip list | grep jupyter 

卸载包

pip uninstall jupyter-client jupyter-core jupyter-server jupyterlab jupyterlab jupyterlab-server jupyterlab-widgets

重新安装

pip install jupyter-client jupyter-core jupyter-server jupyterlab jupyterlab jupyterlab-server jupyterlab-widgets
