Inference with AidLite SDK

sudo aid-pkg update
sudo aid-pkg install aidlite-sdk
sudo aid-pkg install aidlite-qnn248

cd run_yolo26x-obb
python3.10 code/python/run_test.py \
  --target_model ./models/QCS8550/FP16/yolo26x-obb_qcs8550_fp16.qnn248.ctx.bin \

  --invoke_nums 10

The converted package exposes output0: [1, 20, 21504], i.e. xywh (4) + 15 DOTAv1 class scores + angle (1) for 21504 anchors. Decoding uses the Ultralytics OBB head layout and probabilistic-IoU NMS.
