Is there a visual profiler for Python?

 

I use cProfile now but I find it tedious to write pstats code just to query the statistics data.

I'm looking for a visual tool that shows me what my Python code is doing in terms of CPU time and memory allocation.

Some examples from the Java world are visualvm and JProfiler.

  • Does something like this exist?
  • Is there an IDE that does this?
  • Would dtrace help?

    • I know about KCachegrind for Linux, but I would prefer something that I can run on Windows/Mac without installing KDE.

    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.

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    Update: Unfortunately it seems that RunSnakeRun is no longer maintained, and it does not support Python 3.

    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.
