JupyterLab 交互式笔记本的安装使用

    科技2022-07-16  111

    介绍

    JupyterLab 是基于 Web 的交互式开发环境,是 Jupyter 下一代的 Notebook 界面。

    可以处理 Jupyter notebooks (.ipynb),编辑文本 (.md, .csv, .json, …),查看文件 (images, PDF, …),操作终端等。

    另外,

    交互式,指文本与代码的交互。意味着文本中的代码,如 Markdown 代码段,可直接运行。开发环境,表明其功能足够强大,更像是一个 IDE 。扩展插件也让我们能自定义或增强各种功能。 官方文档: https://jupyterlab.readthedocs.io/

    安装

    推荐以下两种方式之一:

    Anaconda: Anaconda 是用于科学计算的 Python 发行版,自带有 JupyterLab 。Docker: Docker 是一个开源的容器引擎,可以直接拉取 JupyterLab 镜像环境。

    Anaconda

    下载地址: https://www.anaconda.com/products/individual#Downloads

    conda 查看:

    ❯ conda list | grep jupy jupyter 1.0.0 py37_7 jupyter_client 5.3.4 py37_0 jupyter_console 6.1.0 py_0 jupyter_core 4.6.1 py37_0 jupyterlab 1.2.6 pyhf63ae98_0 jupyterlab_server 1.0.6 py_0

    安装:

    conda install -c conda-forge jupyterlab

    或更新:

    conda update -c conda-forge jupyterlab

    开始使用

    jupyter lab

    浏览器会打开:

    Docker

    下载地址: https://docs.docker.com/engine/install/

    拉取镜像:

    docker pull jupyter/scipy-notebook:latest

    常驻运行:

    docker run -d --restart=always \ --name jupyter \ -p 8888:8888 \ -e JUPYTER_ENABLE_LAB=yes \ -v "$HOME":/home/jovyan/work \ jupyter/scipy-notebook:latest --restart=always 是为了重启后仍保持运行$HOME 是用于映射进容器的本地工作路径

    浏览器访问 http://localhost:8888/lab : 提示输入 Token ,可以查看 jupyter 日志获取:

    ❯ docker logs jupyter Executing the command: jupyter lab [I 22:32:45.229 LabApp] Writing notebook server cookie secret to /home/jovyan/.local/share/jupyter/runtime/notebook_cookie_secret [I 22:32:46.051 LabApp] JupyterLab extension loaded from /opt/conda/lib/python3.8/site-packages/jupyterlab [I 22:32:46.051 LabApp] JupyterLab application directory is /opt/conda/share/jupyter/lab [I 22:32:46.054 LabApp] Serving notebooks from local directory: /home/jovyan [I 22:32:46.054 LabApp] Jupyter Notebook 6.1.4 is running at: [I 22:32:46.054 LabApp] http://e1839b94c616:8888/?token=fc8d547d3d9cb47ae8d855fbb3f788e0c045e0061012a917 [I 22:32:46.054 LabApp] or http://127.0.0.1:8888/?token=fc8d547d3d9cb47ae8d855fbb3f788e0c045e0061012a917 [I 22:32:46.054 LabApp] Use Control-C to stop this server and shut down all kernels (twice to skip confirmation).

    最终,输入 token fc8d547d3d9cb47ae8d855fbb3f788e0c045e0061012a917 登录。

    Chrome 浏览器可以应用 Chrome Apps 创建桌面快捷。
