这个还是要标注训练，麻烦

IMAGES_URI = "https://dl.fbaipublicfiles.com/dinov3/notebooks/foreground_segmentation/foreground_segmentation_images.tar.gz"
LABELS_URI = "https://dl.fbaipublicfiles.com/dinov3/notebooks/foreground_segmentation/foreground_segmentation_labels.tar.gz"def load_images_from_remote_tar(tar_uri: str) -> list[Image.Image]:images = []with urllib.request.urlopen(tar_uri) as f:tar = tarfile.open(fileobj=io.BytesIO(f.read()))for member in tar.getmembers():image_data = tar.extractfile(member)image = Image.open(image_data)images.append(image)return imagesimages = load_images_from_remote_tar(IMAGES_URI)
labels = load_images_from_remote_tar(LABELS_URI)
n_images = len(images)
assert n_images == len(labels), f"{len(images)=}, {len(labels)=}"print(f"Loaded {n_images} images and labels")

dense_sparse_matching这个可能比较不麻烦
