The Python extension loader(PEL) is a Java extension that manages the Python extensions built using the altair-aitools-devkit package. The PEL seamlessly integrates the Python extensions into the Altair AI Tools ecosystem.

What does PEL do?

• Loads operator definitions from Python extensions (names, parameters, ports, etc.)
• Manages the execution of Python code using the appropriate Python distribution
• Handles data serialization between Java and Python
• Makes Python extensions appear and behave just like native AI Studio operators in your workflows
