python-crfsuite for Ubuntu

I want to install python-crfsuite in Ubuntu. When I install using pip, I'm getting some warning and

Could not find .egg-info directory in install record for python-crfsuite

When I import crfutils in python, it is saying module not found. What could be the problem or is it is not possible in Linux system?

Solution

  • Install important tools

    $ apt-get install swig

    Download the dependencies.

    $ wget https://github.com/downloads/chokkan/liblbfgs/liblbfgs-1.10.tar.gz

    Decompress. Go to the resulting directory. Type ./configure. Then make. Then make install.

    Download the actual software source.

    $ wget https://github.com/downloads/chokkan/crfsuite/crfsuite-0.12.tar.gz

    Decompress the file. Go to the resulting directory. Type ./configure. Then make. Go to the swig>python directory. Type 

    $ ./prepare.sh --swig
$ python setup.py build_ext
$ python setup.py install

    You may need to manually edit export_wrapper.cpp, but the fix is included in README

    You may need to add /usr/local/lib to LD_LIBRARY_PATH if you get ImportError: libcrfsuite-0.12.so.
