请问您是如何将.onnx转换成rknn的呢

[jumengbo]

我想要将自己的训练的模型转换为rknn来预测,.pt转换为onnx的方法是用你readme里面提到的kaylorchen

You need the rknpu2 toolkit and the rknn_model_zoo.
Here, you find https://github.com/airockchip/rknn_model_zoo/tree/main/examples/yolov8/python, for instance.
The Python convert.py can be used to get the rknn model.
Keep in mind that every type of model (YoloV5, YoloV6, YoloV7, or YoloV10) has it's own convert.py.
If not sure, check with kaylorchen to get the right one.
I thought he uses YoloV8.

这些工具包我是用过,在kaylorchen那里我找到了将pt转换为onnx和onnx转换为rknn方法,在转换为onnx之后,转化为rknn时遇到了问题,问题如下,我在尝试自己解决并询问[kaylorchen],谢谢你的回答

Please consult kaylorchen.
