The machine learning software’s core data mining algorithms include classification, clustering, and regression. With Weka download, the collection of algorithms ranges from the ones able to handle data modelling to pre-processing. The program can be used to develop new ML (machine learning) schemes. The app comes with all the tools required for data classification, clustering, pre-processing, regression, visualisation, association rules, and more. Users can apply the algorithms directly to a data set or call them from custom Java code. Its primary objective is to solve real-world data mining problems. Python -c 'import as jvm jvm.start() jvm.Weka is a comprehensive data mining tool with a huge collection of machine learning algorithms. virtual environment for Python 3.6 (anaconda3-2019.07): conda create -n pww36 python=3.6 Python -c 'import as jvm jvm.start() jvm.stop()'Ĥ. virtual environment for Python 2.7 (anaconda3-2019.07): conda create -n pww27 python=2.7 Pww36/bin/python -c 'import as jvm jvm.start() jvm.stop()'ģ.

Pww27/bin/pip install python-weka-wrapper virtual environment for Python 2.7 (virtualenv): virtualenv -p /usr/bin/python2.7 pww27 OK, let's create the virtual environments and test them:ġ. This command will generate output similar to the following (paths will be different, of course): DEBUG::Adding bundled jarsĭEBUG::Classpath=ĭEBUG::Package support disabled The instructions below create directories ( pww27 and pww36 in your current directory), which you can simply delete, if you no longer require these virtual environments.īut, I've also listed instructions on how to use Anaconda further below.Įach of the virtual environments will run a test command: import the jvm module, start and stop the JVM, using python -c '.', to check whether the environment is working. I'm not a big fan of Anaconda, as I find it overkill, especially since virtualenv does things in a much leaner, cleaner and faster way. Though Oracle JDK is recommended, you can get it to work with OpenJDK as well, just make sure to install the sources as well: sudo apt-get install openjdk-8-source openjdk-8-jdk I'm not sure what you're doing wrong in your install, but here are the steps that I performed to get python-weka-wrapper installed for Python 2.7 and 3.6, on a freshly installed (and fully up-to-date) Ubuntu 18.04.1:įirst, ensure to have pip installed and you can compile source code: sudo apt-get install python-pip python3-pip virtualenv build-essential
