Profiling Python with valgrind

Tweet 1. Under Linux, install valgrind as follows (Fedora):

sudo yum install valgrind kcachegrind

1	sudo yum install valgrind kcachegrind

and pyprof2calltree:

pip install pyprof2calltree

1	pip install pyprof2calltree

2. create a Python script (let us call it run.py) 3. Create the file containing the profile information using valgrind/callgrind

python -m cProfile  -o profile_data.pyprof run.py
pyprof2calltree -i profile_data.pyprof  # this converts the stats into a callgrind format

1 2	python -m cProfile -o profile_data.pyprof run.py pyprof2calltree -i profile_data.pyprof # this converts the stats into a callgrind format

4. Visualisation

kcachegrind profile_data.pyprof.log

1	kcachegrind profile_data.pyprof.log

Alternatively, for visualisation, … Continue reading →
