There are AIML interpreters in many languages used to load the AIML knowledge base and interact with it. One of the easiest ways of loading and interacting with AIML files is using an AIML interpreter in Python called PyAIML. The PyAIML module can read all the categories, patterns, and templates and can build a tree. Using a backtracking depth-first search algorithm, it can search for the appropriate response from the user in order to give the proper reply.

PyAIML can be installed on Windows, Linux, and Mac OS X. In Ubuntu, there are prebuilt DEB binaries that we can install from Software Center. We can also install PyAIML from source code. The current PyAIML will work well in Python 2.7. Let's look at how we can install it.
