jupyter安装nbextentions

使用pip安装

pip install jupyter_contrib_nbextensions

jupyter contrib nbextension install --user

pip install jupyter_nbextensions_configurator

jupyter nbextensions_configurator enable --user

如果失败，可以使用conda安装

conda install -c conda-forge jupyter_nbextensions_configurator
conda install -c conda-forge jupyter_contrib_nbextensions
jupyter contrib nbextension install --user
jupyter nbextensions_configurator enable --user

重启notebook后界面有一个新栏，示意如下：

最爱的是代码折叠codefolding，可以勾选启用，也可以用代码启用(enable)/禁用(disable)

jupyter nbextension enable codefolding/main

效果如下：
