In this guide we will walk you through setting up your VOC environment for development and testing. We will assume that you have a working Python 3, JDK, Apache ANT installation and use virtualenv.

The default version apt-get provides on Ubuntu 16.04 is 3.5+ but VOC won’t build on Python3.5+. Hence, a separate Python 3.4+ installation would be required.

Checking Dependencies

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

$ python --version
Python 3.4.4

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

$ javac -version
javac 1.7.0_101

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

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

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:

$ virtualenv -p $(which python3) env
$ . env/bin/activate
$ cd voc
$ pip install -e .

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

> virtualenv -p "C:\Python35\python.exe" 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.
