Most likely, your end goal is not to generate jars but to exectue scikit-learn models (either for training or predictions or maybe both) on a Java virtual machines. Nobody on earth is interested in generated jar files per se :) > Question 1: Is it possible to create Jar file from Python ? Or Should I use > Jython for the JAR file ? A jar is mostly a zip archive that holds the byte code of compiled java classes and additional resources such as configuration files or data files used by the java classes. Python can allow you to create a zip archive but as it won't allow you to compile java code to generate the java byte code so I don't see the point of generating jar files from python. Use a Java build tools (OpenJDK + ant or maven for instance) to build your jars. > Question 2: If I need to use Jython, I was wondering if it’s possible to > install/use ScikitLearn in Jython and all my code that I develop in Python > ? Nope because jython will not allow you to use C compiled extensions. And both scikit-learn and its dependencies (numpy and scipy) are full of compiled C extensions. The only Python intepreter able to execute scikit-learn / numpy and scipy as of today is CPython (the official python interpreter from python.org). Maybe you should have a look at jepp or jpype instead (depending if you want to call CPython programs from a Java runtime or the converse): http://jepp.sourceforge.net/ http://jpype.sourceforge.net/ See also: http://stackoverflow.com/questions/12738827/how-can-i-call-scikit-learn-classifiers-from-java -- Olivier http://twitter.com/ogrisel - http://github.com/ogrisel ------------------------------------------------------------------------------ Everyone hates slow websites.
