1. Under Linux, install valgrind as follows (Fedora):
sudo yum install valgrind kcachegrind |
and pyprof2calltree:
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 |
4. Visualisation
kcachegrind profile_data.pyprof.log |
Alternatively, for visualisation, you can also use gprof2dot and graphviz (dot):
gprof2dot.py --format=callgrind --output=out.dot profile_data.pyprof.log dot -Tsvg out.dot -o graph.svg |
