Importing from pyinstrument (python)
Jamie Wong edited this page May 17, 2022 · 1 revision
pyinstrument is a statistical profiler for Python.
pyinstrument has an explicit output format for speedscope (See: https://github.com/joerick/pyinstrument/pull/160).
To profile a Python script and view the output in speedscope, run:
pyinstrument -r speedscope -o profile.speedscope.json your_script.py Or, you can profile a specific block of code using:
from pyinstrument import Profiler from pyinstrument.renderers import SpeedscopeRenderer with Profiler() as profiler: ... # your code here with open('profile.speedscope.json', 'w') as f: f.write(profiler.render(renderer=SpeedscopeRenderer())) Then drop the resulting profile.speedscope.json into https://www.speedscope.app/
