# AMD SMI Python API reference

The AMD SMI Python interface provides a convenient way to interact with AMD
hardware through a simple and accessible API. Compatible with Python 3.6 and
higher, this library requires the AMD driver to be loaded for initialization --
review the [prerequisites](#install_reqs).

This section provides comprehensive documentation for the AMD SMI Python API.
Explore these sections to understand the full scope of available functionalities
and how to implement them in your applications.
