Good day to whichever beautiful person is reading this. I’m currently working on a project with which i would like to identify different sorts of Dutch fryable snacks. I have trained myself a yolov5 model, which i can convert to the .onnx format, or the .pb format. Only thing is, i’m having a lot of trouble finding example material and understandable information on how to properly implement the model into OpenCV. I have already checked the [documentation](https://docs.opencv.org/4.x/dc/d70/pytorch_cls_tutorial_dnn_conversion.html) but i’m still having difficulty getting it up and running. I’m wondering if anyone here has some good examples available, or another source of information which i could use. Thank you for reading and have a good day. ---

I that’s no wonder it only _works_ since a few weeks, so make sure to use latest code for all this. assuming , you did ``` git clone https://github.com/ultralytics/yolov5 cd yolov5 ... train your model ... ``` you can export it to onnx using: ``` python export.py --weights yolov5s.pt --img 640 --opset 12 --include onnx ``` (opset version seems crucial !) unfortunately, the result parsing differs _a lot_ from v3 or v4, and so far, we only have a working c++ example code here (at least, give it a star, please !): > **[GitHub - UNeedCryDear/yolov5-opencv-dnn-cpp: 使用opencv模块部署yolov5-6.0版本](https://github.com/UNeedCryDear/yolov5-opencv-dnn-cpp)** > > 使用opencv模块部署yolov5-6.0版本. Contribute to UNeedCryDear/yolov5-opencv-dnn-cpp development by creating an account on GitHub. hopefully someone will port it to python soon, gl in the meantime… ---
