How to optimize the speed of YOLOE on edge devices (e.g. iPhone)?

2025-08-27 1.6 K

Performance Bottleneck Analysis

YOLOE默认在T4 GPU达102.5FPS,但iPhone12仅27.2FPS。提升策略:

核心优化步骤:

  • 模型轻量化:
    1. utilizationexport.py转换为CoreML格式时添加--half启用FP16量化
    2. pass (a bill or inspection etc)onnxslim工具剪枝冗余算子(可减小30%体积)
  • 设备适配:
    • iOS端调用ANE(Apple Neural Engine)加速:
      python export.py --checkpoint yoloe-s.pt --include coreml --ios
    • 禁用实时分割(--task detect)提升2倍速度

Options:

  1. 改用YOLOE-S小模型(速度提升1.8倍,精度下降5%)
  2. 部署TensorRT引擎(NVIDIA Jetson设备)
  3. 启用多线程推理(修改predict.py中torch.set_num_threads(4))
