JupyterLab 概述#

Note

JupyterLab is the next-generation web-based user interface for Project Jupyter.
JupyterLab enables you to work with documents and activities such as Jupyter notebooks, text editors, and terminals in a flexible, integrated, and extensible manner.

官网：https://jupyterlab.readthedocs.io/en/stable/

JupyterLab 的功能#

  • Jupyter notebooks (.ipynb files) are fully supported in JupyterLab（核心功能）.

  • Use Code consoles.

  • Use Terminals.

  • Multiple views of documents with different editors or viewers（分屏）.

  • JupyterLab offers a unified model for viewing and handling data formats.

那为什么要使用 JupyterLab 呢？Personally:

  1. 确实很适合做数据科学。

  2. 别人也在用 Jupyter notebooks（或者类似的 Google colab），比如说某些 GitHub 项目、很多 Coursera 课程的作业、《Dive into Deep Learning》每个页面都是一个 notebook、去 Kaggle 参加比赛需要自己写 notebook 等。

  3. 用来写 Markdown 文档。

  4. 用来写 Jupyter Book（我们将在第二部分做详细介绍）。

安装 JupyterLab#

通过 pip 安装：

pip install jupyterlab

通过 conda 安装：

conda install -c conda-forge jupyterlab

启动 JupyterLab#

Once installed, launch JupyterLab with:

jupyter lab

JupyterLab will open automatically in your browser（本地运行的 JupyterLab 的 url 一般是 http://localhost:8888/lab）:

launch

You may also access JupyterLab by entering the notebook server’s URL into the browser:

http(s)://<server:port>/<lab-location>/lab

Jupyter 界面#

Note

While JupyterLab has many features found in traditional IDEs, it remains focused on interactive, exploratory computing. The JupyterLab interface consists of a main work area containing tabs of documents and activities, a collapsible left sidebar, and a menu bar.

Left Sidebar 从上到下依次是:

  • a file browser,

  • a list of tabs in the main work and of running kernels and terminals,

  • the table of contents,

  • the extension manager.

Menu Bar 和 Main Work Area functioning as you expected.
