Introduction

Model Accuracy Analyzer only compares the computation results on Ascend AI Processor of Huawei proprietary operators with those of third-party equivalents. You need to analyze the comparison result and locate problems. However, result analysis is a difficult task. This section describes how to use the Advisor system to analyze accuracy comparison results, which effectively reduces the troubleshooting time.

Currently, the following analysis detection types are supported: FP16 overflow/underflow detection, input inconsistency check, and network-wide consistency check (faulty node detection, single-point error detection, and consistency check).
