jupyter notebook extensions

Jupyter Notebook Extensions 是一组用于增强 Jupyter Notebook 功能的插件。这些扩展可以提供额外的功能和工具，使得在 Jupyter Notebook 中进行科学计算、数据分析和可视化更加方便和高效。一些常用的 Jupyter Notebook Extensions 包括：

1. Table of Contents (目录)：可在 Notebook 中生成一个动态的目录，方便快速导航和查找笔记本中的内容。

2. Code Prettify (代码美化)：可以自动对 Notebook 中的代码进行格式化和美化，使其更易读和易于理解。

3. Autopep8 (自动代码风格修正)：能够自动检测并修复代码中的风格问题，例如缩进、行长等。

4. Collapsible Headings (折叠标题)：可以将 Notebook 中的标题部分折叠起来，以便更好地管理和组织笔记本的内容。

5. Variable Inspector (变量检查器)：可以查看当前 Notebook 中定义的所有变量及其属性，方便进行调试和分析。

6. ExecuteTime (执行时间)：可以显示每个单元格的执行时间，以帮助评估 Notebook 的性能和优化代码。

7. Nbextensions Dashboard Tab (扩展仪表板)：提供了一个交互式仪表板，用于管理和配置已安装的 Jupyter Notebook Extensions。

Jupyter command `jupyter-contrib` not found.

The `jupyter-contrib` command is not a built-in command in Jupyter. It is a package that needs to be installed separately. You can install it using pip by running the following command in your terminal:

pip install jupyter_contrib_nbextensions

After installing the package, you can enable the extensions by running the following command:

jupyter contrib nbextension install --user

This will install a set of useful extensions that can enhance your Jupyter experience. You can then enable individual extensions by going to the Jupyter Notebook dashboard and selecting the `Nbextensions` tab.
