# Got on error?
# openfst installed site-package under `/usr/local/lib/python2.7/site-packages`
# check if the site-package is and should not match above...
python -m site --user-site
# one way to quickly fix is to add the site-package to your python path
export PYTHONPATH=$PYTHONPATH:"/usr/local/lib/python2.7/site-packages"
# then run `import pywrapfst` should be successful
