python subprocess shouldn't run from within the folder -

-

i trying use c&c nlp library in mac , uses terminal interface. naturally i'm trying run command python, here's happens: 

candc:could not open model configuration file reading:models/config

turns out candc should not called same directory, , should called outside of binary folder, "bin/candc". how can make work?

this code: 

cmd="candc/bin/candc --models models"   subprocess.check_output('{} | tee /dev/stderr'.format( cmd ), shell=true)

pass cwd argument desired working directory.

for example, if want run bin/candc candc directory:

import os cmd="bin/candc --models models"   subprocess.check_output('{} | tee /dev/stderr'.format( cmd ), shell=true, cwd=os.path.abspath('candc'))

(i'm not sure whether need os.path.abspath. test both , without it.)
