Depth-Anything Example
This document describes how to use the QAI AppBuilder Python API to run inference with the Depth-Anything depth estimation model on Qualcomm® Hexagon™ Processor (NPU).
Supported devices
| Device | SoC |
|---|---|
| Fogwise® AIRbox Q900 | QCS9075 |
Install QAI AppBuilder
-
Install QAI AppBuilder by following the QAI AppBuilder installation guide.
-
Configure ADSP environment variables as described in Create ADSP environment variables.
Run the sample
Install dependencies
Install sample dependencies in the activated virtual environment:
pip3 install requests tqdm qai-hub py3-wget Pillow torch torchvision opencv-python-headless matplotlib
Run the script
-
Enter the upstream samples directory
Devicecd qai-appbuilder/samples -
Prepare input data (use the sample input if provided, or pass script arguments)

The first run downloads the model via Qualcomm® AI Hub (network-dependent). You can also use the launcher from samples:
python3 run_inference.py --list
python3 run_inference.py --model depth_anything --args "--chipset 9075"
