A Jupyter Notebook Extension for DolphinDB.

Project description

DolphinDB Jupyter Notebook 扩展插件

Jupyter Notebook是基于网页的用于交互计算的应用程序。用户可以直接通过浏览器编辑和交互式运行代码。DolphinDB database 提供了Jupyter Notebook的插件。

DolphinDB Jupyter Notebook 扩展插件提供以下功能:

  • 为用户提供Jupyter Notebook连接DolphinDB Server的配置界面。
  • 使Jupyter Notebook支持DolphinDB脚本语言的执行。

1. 下载插件并安装

  • 使用pip安装

    pip install dolphindb_notebook

  • 启用插件

    jupyter nbextension enable dolphindb/main

2. 配置Jupyter Notebook工作路径

Jupyter Notebook内核(kernels)是编程语言特定的进程,它们独立运行并与Jupyter应用程序及其用户界面进行交互。DolphinDB Jupyter Notebook 扩展插件提供了运行DolphinDB脚本的内核。用户需要通过以下步骤配置Jupyter Notebook的工作路径,以便在程序运行时DolphinDB内核的顺利导入。

  • 通过命令行jupyter kernelspec list查看Jupyter Notebook内核的工作路径。

    • Linux系统
    >jupyter kernelspec list
    Available kernels:
        dolphindb   /home/admin/.local/share/jupyter/kernels/dolphindb
        python3       /home/admin/.local/share/jupyter/kernels/python3
    

    将/home/admin/.local/share/jupyter/kernels复制下来,方便下一步配置时粘贴。

    • Windows系统
    >jupyter kernelspec list
    Available kernels:
        dolphindb   C:\Users\admin\appdata\local\programs\python3\python37\share\jupyter\kernels\dolphindb
        python3       C:\Users\admin\appdata\local\programs\python3\python37\share\jupyter\kernels\python3
    

    将 C:\Users\admin\appdata\local\programs\python3\python37\share\jupyter\kernels复制下来,方便下一步配置时粘贴。

  • 通过命令行jupyter notebook --generate-config生成一个配置文件jupyter_notebook_config.py,打开这个配置文件,找到c.NotebookApp.notebook_dir选项,设为上一步复制下来的工作路径,并去掉注释#。 注意:Windows系统需要将路径中的一个反斜杠\都替换成两个反斜杠\\,其中一个是转义字符。

3. 连接DolphinDB Server

  • 在命令行输入jupyter notebook,启动Jupyter Notebook。
  • 在Jupyter Notebook的页面右侧点击新建,选择DolphinDB,新建一个DolphinDB notebook。
  • 点击notebook工具栏的Connect to DolphinDB Server按钮。选择相应的server,然后点击右下角Connect按钮,即与DolphinDB server建立连接(如果不需要该server,可以点击Delete按钮删除)。
  • 也可以通过New按钮,输入新的server信息,然后点击Save & Connect按钮即与DolphinDB server建立连接,并保存该信息以便下次使用。

4. 编辑和运行DolphinDB脚本

连接DolphinDB Server后,在代码块区域编写DolphinDB脚本,点击运行即可运行相应代码块。

5. 展示代码块运行结果

每次运行DolphinDB脚本后,运行结果都会在相应的代码块下方展示。对于DolphinDB的绘图功能,以PNG展示结果。

注意:

  • 对于一些数据量较大的结果,可能会出现IOPub数据率超出限制的问题,可以启用 Jupyter Notebook配置文件中的 c.NotebookApp.iopub_data_rate_limit 这一项,按需调高数值。
  • 对于超出60行的表格,只显示前五行与后五行。
