Facial-Attribute-Detection Example

This document describes how to use the QAI AppBuilder Python API to run inference with the Facial-Attribute-Detection face attribute recognition model on Qualcomm® Hexagon™ Processor (NPU).

Supported Devices

DeviceSoC
Fogwise® AIRbox Q900QCS9075

Install QAI AppBuilder​

tip

  1. Please install QAI AppBuilder according to QAI AppBuilder Installation Guide.

  2. Please configure ADSP environment variables according to Create ADSP Environment Variables.

Run the Example​

Install Dependencies​

Device
