Luckfox Forums

Hi,

I am trying to deploy my custom model to the Luckfox Pico RV1106 board. I trained a YOLOv5n model with only one class. Then, I cloned the repository from https://github.com/airockchip/yolov5.git and ran the command:
python export.py --rknpu --weight best.pt

After that, I cloned the repository from https://github.com/airockchip/rknn_model_zoo.git.
cd examples/yolov5/python
python3 convert.py /weight/best.onnx rv1106

Then

After I send the folder to the board and...

I get this error.

Check if the exported ONNX model is complete and meets the requirements of RKNN. You can use tools such as Netron to check if the structure of the ONNX model is correct.Reference manual RKNN supports operation waiting list:(https://github.com/rockchip-linux/rknn- ... v1.6.0.pdf). I used the official YOLOv5n model and the results were correct. The link is as follows: ( https://github.com/ultralytics/yolov5/r ... yolov5n.pt)
