Python interface to Moses

The idea is to have some of Moses' internals exposed to Python (inspired on pycdec).

What's been interfaced?

• Binary phrase table:

    Moses::PhraseDictionaryTree.h
  

Building

1. Build the python extension:

   You need to compile Moses with link=shared and (for while) without SRILM (for some reason SRILM prevents the compiler from generating libLM.so)

   ./bjam --libdir=path cxxflags=-fPIC link=shared
   

   Then you can build the extension (in case you used --libdir=path above, use --moses-lib=path below)

   python setup.py build_ext -i [--with-cmph] [--moses-lib=path]
   

2. Check the example code

   echo "casa" | python example.py examples/phrase-table 5 1
   echo "essa casa" | python example.py examples/phrase-table 5 1
   

Changing the code

If you want to add your changes you are going to have to recompile the cython code.

1. Compile the cython code (use Cython 0.16): this will generate binpt/binpt.cpp

   cython --cplus binpt/binpt.pyx
