Profile Python

Profiling Python apps (e.g., app.py)

pip3 install cProfile
sudo apt install pyprof2calltree

launch your code via:

python3 -m cProfile -o app.cprof app.py

pyprof2calltree -k -i app.cprof

Note that the latter will call kcachegrind. On old versions of kcachegrind the time unit is not given directly. It should be in the Short description field of the event type and is nanoseconds on my device.
