The project lives on GitHub, where you can report issues, contribute to the project by forking the project then creating a pull request, or just browse the source code.

The documentation needs some work stiil. Feel free to contribute :)

Features

  • Support for Python 2.7+ and Python 3.3+.

  • Static visualizations of the call graph using various tools such as Graphviz and Gephi.

  • Execute pycallgraph from the command line or import it in your code.

  • Customisable colors. You can programatically set the colors based on number of calls, time taken, memory usage, etc.

  • Modules can be visually grouped together.

  • Easily extendable to create your own output formats.

Quick Start

Installation is easy as:

pip install pycallgraph

You can either use the command-line interface for a quick visualization of your Python script, or the pycallgraph module for more fine-grained settings.

The following examples specify graphviz as the outputter, so it’s required to be installed. They will generate a file called pycallgraph.png.

The command-line method of running pycallgraph is:

$ pycallgraph graphviz -- ./mypythonscript.py

A simple use of the API is:

from pycallgraph import PyCallGraph
from pycallgraph.output import GraphvizOutput

with PyCallGraph(output=GraphvizOutput()):
    code_to_profile()

Documentation

Feel free to browse the documentation of pycallgraph for the usage guide and API reference.
