About：wanrning：“None of the inputs have requires_grad=True. Gradients will be None“

[Lemonaadee]

I'm reaching out regarding an issue I've encountered while working with the model. I'm receiving a warning that says, 'None of the inputs have requires_grad=True. Gradients will be None.' I've been trying to troubleshoot this and was wondering if you might have insights into resolving this particular warning.

From my understanding, it seems like there might be an issue related to the setting of the requires_grad attribute for the inputs, leading to the absence of gradients during the training process. But the inputs(images) should not be set "requires_grad=True"

Could you kindly offer guidance or share any specific steps or considerations to address this warning? Any advice or direction you could provide would be greatly appreciated.

Thank you very much for your time and assistance.
