Within a script:

 # At the top of the file in global
  scope # next to the imports import cProfile as profile pr = profile.Profile()
  pr.disable() # right before the function call to profile pr.enable() # right
  after the function call to profile pr.disable() # Now save results to file,
  with # This should only be called once, if in doubt # place right before your
  program exits. pr.dump_stats('profile.pstat') 
For a script files:
 python -m cProfile -o profile.pstat 
 pip install pyprof2calltree
  pyprof2calltree -i profile.pstat -o script.calltree kcachegrind
