JupyterLab 交互式笔记本

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。

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:
