Another quick question. When calculating the derivative, why not considering the case of d L_k / dw_m, (when m not equals to k)?

@hbb1 Thanks a lot for your prompt reply. I tried to understand how the backward is implemented these days but still a bit confused. I would be very appreciative if...

@hbb1 Really appreciate your prompt reply. I can understand most of the parts until the last sentence on $dL/d a_k$. Because of occlusion $\frac{\partial w_i}{\partial a_k}=0$ where $i < k$,...

@ranrandy Hi, thanks a lot for your explanation. Now it is clear to me how the derivative is obtained. Appreciate it!

Haha, thanks a lot :)

@vagr8 Thanks a lot for your prompt reply! This is really helpful for me:). May I also ask if we need a ground truth for each image in the training...

Thanks a lot for your detailed reply and the uploading of your latest code! Now I understand it. I will check your latest code. :)

Btw, I find a but [here](https://github.com/UNeedCryDear/yolov8-opencv-onnxruntime-cpp/blob/6bccffea393f019038b8c91b14f3e4fb8829e7f1/yolov8_utils.h#L26C4-L26C44): It should be `bool CheckModelPath(const std::string & modelPath);`

Thanks a lot for this information.

Hi, I got the same error before. I evaluated via another laptop, and the issue is gone. I am using opencv4.5.
