EXPOSE 8888
ENTRYPOINT ["jupyter","lab","--ip=0.0.0.0","--allow-root","--no-browser"]

# Jupyter Lab 配置
# 使用 Pycharm/VSCode/其他 IDE 编辑代码，这部分可以全部注释掉
jupyterlab # Jupyter Lab 本体
jupyterlab-language-pack-zh-CN # Jupyter Lab 中文语言包
jupyterlab-lsp # Jupyter Lab 语言服务器（LSP）支持
jedi-language-server # Jedi 语言服务器

# 其他需要的包
ipykernel # 运行 Jupyter Notebook 的核心包，使用 VSCode 时需要
scipy # 提供一些实用函数
pandas # 数据处理包，可以注释掉
matplotlib # 绘图包，如果需要导出数据用其他软件绘图，可以注释掉
