YOLO V8/V9 ONNX Conversion Error to RKNN

[aayushb-95]

Hi,
I am trying to convert YoloV8/V9 ONNX model to RKNN. However, I am getting the following error :

W rknn-toolkit version: 1.7.5
W Catch exception when optimize onnx model, skip it! Exception: Unresolved value references: /model.10/Constant_1_output_0,/model.10/Constant_output_0,/model.13/Constant_1_output_0,/model.13/Constant_output_0,/model.22/Constant_10_output_0,/model.22/Constant_11_output_0,/model.22/Constant_12_output_0,/model.22/Constant_1_output_0,/model.22/Constant_2_output_0,/model.22/Constant_3_output_0,/model.22/Constant_4_output_0,/model.22/Constant_5_output_0,/model.22/Constant_6_output_0,/model.22/Constant_7_output_0,/model.22/Constant_8_output_0,/model.22/Constant_9_output_0,/model.22/Constant_output_0,/model.22/dfl/Constant_1_output_0,/model.22/dfl/Constant_output_0,
