In this section, we will discuss a few more tools that will aid the programmer in debugging memory leaks and also enable them to visualize their objects and their relations.
objgraph (object graph) is a Python object visualization tool that makes use of the
graphviz package to draw object reference graphs.
It is not a profiling or instrumentation tool but can be used along with such tools to visualize object trees and references in complex programs while hunting for elusive memory leaks. It allows you to find out references to objects to figure out what references are keeping an object alive.
As with almost everything in the Python world, it is installable via
$ pip3 install objgraph
However objgraph is really useful only ...
