This program depends on: -- python2.6 or higher -- logilab.hmm module And logilab.hmm module depends on: -- Mercurial (for grabing out files) -- numpy -- gcc -- gfortran (or any other fortarn compiler supported by setup.py) INSTALL To do a typical (userland) installation of logilab.hmm: $ apt-get install python python-dev python-numpy gfortran mercurial $ hg clone http://hg.logilab.org/logilab/hmm Then we'll have the installation script setup.py in hmm. $ cd hmm/ $ python setup.py install -user To test if installation is finished you may do the following steps: $ python from logilab.hmm import HMM No news is good news. I haven't done this on Windows platform. Theorically, you'll need mingw, a supported fortarn compiler and sci-py package.
