运行yolo v8 YOLOv8-CPP-Inference C++部署遇到的问题

环境：
openCv:4.8.0
torch: 2.0.0
cuda:cuda_11.7.r11.7

遇到问题1：

问题1解决：
问题很简单，就是onnx模型导出的imgsz参数不对。修改后的参数如下

from ultralytics import YOLO

# Load a YOLOv8 model
model = YOLO("yolov8s.pt")

# Export the model
model.export(format="onnx", opset=12,dynamic=False,imgsz=[480,640])

遇到问题2：

问题2解决：
原来的openCV版本是4.5.4 更新到4.8.0就可以
