AttributeError: 'list' object has no attribute 'cpu'

[pawara101]

I was using YOLOv12 for EigenCAM. Below is my code block.

from pytorch_grad_cam import EigenCAM
target_layer = get_conv_layer(model_1,conv_layer_name = "model.model.4.cv3")

results_1 = model_1([img_path])
cam_1 = EigenCAM(model=model_1, target_layers=target_layer)

grayscale_cam = cam_1(img_tensor)[0, :, :]

The erroermessage was

---------------------------------------------------------------------------
AttributeError                            Traceback (most recent call last)

    105             targets = [ClassifierOutputTarget(category) for category in target_categories]
    106

Can you help me to fix this ?
