在Apache Zeppelin上运行独立的python脚本 [英] Run standalone python script on Apache Zeppelin

问题描述

我一直在使用

由于它支持Shell解释器％sh ，因此我仅使用它来运行带有参数的独立python脚本.

 ％shpython评估.py gold.csv pred.csv 

如果不确定输入文件和脚本的位置，则可以在Zeppelin段落中运行Shell命令 pwd 来查找它们.

 ％sh密码 

I have been using Apache Zeppelin Notebook for running Scala codes. Now a standalone Python script needs to be run on the same notebook. Scala codes produce some CSV files in the precedding paragraphs which should be passed as arguments to the Python script. What's the easiset way to run the Python script from another paragraph of the same Zeppelin notebook?

解决方案

Zeppelin provides several interpreters which can be binded to a respective notebook. Click on the Interpreter Binding option on the top right side of your notebook to see what's supported by your notebook.

Since it supports the Shell interpreter %sh, I simply use this to run the standalone python script with arguments.

%sh
python evaluate.py gold.csv pred.csv 

If you are not sure about the location of the input file and scripts, you can run the Shell command pwd in a Zeppelin paragraph to find them.

%sh
pwd
