Yolo-v8 Segmentation also consists of bbox

you can change the task to "od" instead of "see" which helps to solve the error.

img = cv2.imread(f'/home/fatemeh/Documents/training datasets/adsf/train/images/{img_name}')
img = cv2.resize(img, (640, 640))
rgb_img = img.copy()
img = np.float32(img) / 255
target_layers =[model.model.model[-4]]
cam = EigenCAM(model, target_layers,task='od')
grayscale_cam = cam(rgb_img)[0, :, :]
cam_image = show_cam_on_image(img, grayscale_cam, use_rgb=True)
plt.imshow(cam_image)
plt.show()
im = cv2.cvtColor(rgb_img, cv2.COLOR_RGB2BGR)
