Developer Tools Usage Tutorials

The ExecuTorch Developer Tools provide capabilities for profiling and debugging your models. We provide step-by-step tutorials for common workflows:

Profiling Tutorial

Please refer to the Profiling Tutorial for a walkthrough on how to profile a model in ExecuTorch using the Developer Tools. This tutorial covers:

• Generating ETRecord and ETDump artifacts

• Using the Inspector API to analyze performance data

• Identifying slow operators and bottlenecks

Debugging Tutorial

Please refer to the Debugging Tutorial for a walkthrough on how to debug numerical discrepancies in ExecuTorch models. This tutorial covers:

• Capturing intermediate outputs with debug buffers

• Using calculate_numeric_gap to identify precision issues

• Debugging delegated models (e.g., XNNPACK)

• Comparing runtime outputs with eager model references
