本文主要是介绍瑞芯微RK3588 C++部署Yolov8检测和分割模型，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
最近这一个月在研究国产瑞芯微板子上部署yolov8的检测和分割模型，踩了很多坑，记录一下部署的过程和遇到的一些问题：
1 环境搭建
需要的环境和代码主要包括：
（1）rknn-toolkit2-1.5.2：工具链，开发环境
（2）rockchip-yolov8：pt模型转onnx模型
（3）yolov8_onnx2rknn：在（2）的基础上转检测rknn模型
（4）yolov8seg_onnx2rknn：在（2）的基础上转分割rknn模型
最好使用对应的环境，环境不匹配的话会出现很多问题。
2 ubuntu docker环境
Docker容器主要用来进行模型转换，也就是pt转onnx的过程，因此docker中需要用的的包主要是rockchip-yolov8,需要修改该代码，进行模型的转换，在linux服务器上安装docker环境，创建一个ubuntu系统的docker环境
这一部分的修改代码参考山水无移大哥的部署过程，贼清洗，膜拜一下，少走了很多弯路，直接贴上地址。
3 模型转换问题
在转自己的pt到onnx模型时，容易出现以下问题：
（1）报错信息：
copying a param with shape torch.Size([64,64,3,3]) from checkpoint,the shape in current model is torch.Size(32,64,3,3)
主要的问题有两种：
1）在最后一步导出onnx时，yolov8s.yaml里面没有修改成自己的模型的类别信息；
2）自己训练的yolov8m模型，但是选择的yaml是yolov8s.yaml
from ultralytics import YOLO# model = YOLO('/cytech_ai/sipingtest/rknntest/model/20230228_yolov8_LiftPerson_filter.pt')
# results = model(task='detect', mode='predict', source='/cytech_ai/sipingtest/rknntest/2.jpg', line_thickness=3, save=True, device='cpu')model = YOLO('/cytech_ai/sipingtest/rknntest/rockchip-yolov8/ultralytics/cfg/models/v8/yolov8s.yaml')
results = model(task='detect', mode='predict', source='/cytech_ai/sipingtest/rknntest/2.jpg', line_thickness=3, save=True, device='cpu')
（2）多处修改时，最终的输出结果和分割模型的结果搞混了，导致模型输出对应不上：
4 RK3588上环境搭建
瑞芯微rk3588上，需要的环境主要是rknpu2，主要用来C++编写cmakelists文件时导入动态库和头文件，我这里将检测模型和分割模型全部集成到一个工程里面，分享一个个人的cmakelist文件：
