Is there a visual profiler for Python? [closed]

Answer 1

Consider pyflame + flamegraph

Pyflame: A Ptracing Profiler For Python + flamegraph

You can trace towards a running python process using pyflame.

Answer 2

A friend and I have written a Python profile viewer called SnakeViz that runs in a web browser. If you are already successfully using RunSnakeRun SnakeViz may not add that much value, but SnakeViz is much easier to install.

Edit: SnakeViz supports Python 2 and 3 and works on all major systems.

Answer 3

KCacheGrind includes a version called QCacheGrind which does run on Mac OS X and on Windows.

Answer 4

I'm only aware of RunSnakeRun.

There was also some talk some time ago about an integrated profiler in PyDev (Eclipse), but I don't know if that will ever see the light of day.

Update: Unfortunately it seems that RunSnakeRun is no longer maintained, and it does not support Python 3.

Answer 5

I use gprof2dot.py. The result looks like this. I use those commands:

  python -m cProfile -o profile.dat my_program.py
  gprof2dot.py -f pstats profile.dat | dot -Tpng -o profile.png

You need graphviz and gprof2dot.py installed. You might like a convenience shell script.

Answer 6

Spyder also provides a pretty nice gui for cProfile:
