python script를 한줄 단위로 profiling해줌
아래의 code snippets으로 쉽게 decorator로 구현 가능
cProfile
import cProfile, pstats, io
from pstats import SortKey
pr = cProfile.Profile()
pr.enable()
self.train_run()
pr.disable()
s = io.StringIO()
sortby = SortKey.CUMULATIVE
ps = pstats.Stats(pr, stream=s).sort_stats(sortby)
ps.print_stats() with open('profile.txt', 'w+') as f: f.write(s.getvalue())
print(s.getvalue())
python -m cProfile ../run_service.py > profile_result.txt
