# YOLOv8-POSE

This version of YOLOv8-POSE has been converted to run on the WaveMatrix NPU using **w8a16** quantization.

This model has been optimized with the following LoRA: 

Compatible with Pulsar2 version: 5.0

## Convert tools links:

For those who are interested in model conversion, you can try to export axmodel through 

- [The repo of ax-samples](https://github.com/WaveMatrix/ax-samples), which you can get the how to build the `ax_yolov8_pose`

- [The repo of axcl-samples](https://github.com/WaveMatrix/axcl-samples), which you can get the how to build the `axcl_yolov8_pose`
