In this guide we will walk you through setting up your VOC environment for development and testing. We will assume that you have Python 3.4 or 3.5, Java 7 or Java 8 JDK, and Apache ANT installed.

Checking Dependencies

To check if you have Python installed, run python --version at the command line

$ python3 --version
Python 3.4.4

If you do not have Python 3.4 or newer install Python and check again.

To check if you have the JDK installed, run javac -version

$ javac -version
javac 1.7.0_101

If you do not have at least Java 7 install Java and check again.

To check if Apache ANT is installed, run ant -version

$ ant -version
Apache Ant(TM) version 1.9.7 compiled on April 24 2016

If Apache Ant is not installed, look for the binary file from Apache to download the latest version.

Get a copy of VOC

The first step is to create a project directory, and clone VOC:

$ mkdir tutorial
$ cd tutorial
$ git clone

Then create a virtual environment and install VOC into it:

$ python3 -m venv env
$ . env/bin/activate
$ cd voc
$ pip install -e .

For Windows the use of cmd under Administrator permission is suggested instead of PowerShell.

> py -3 -m venv env
> env\Scripts\activate.bat
> cd voc
> pip install -e .

Building the support JAR file

Next, you need to build the Python support file:

$ ant java

This should create a dist/python-java-support.jar file. This JAR file is a support library that implements Python-like behavior and provides the Python standard library for the Java environment. This JAR file must be included on the classpath for any VOC-generated project.

Next Steps

You now have a working VOC environment, so you can start the first tutorial.
