 How to use  Here is how to use this model:  ```python from transformers import MaskFormerFeatureExtractor, MaskFormerForInstanceSegmentation from PIL import Image import requests  url = "https://huggingface.co/datasets/hf-internal-testing/fixtures_ade20k/resolve/main/ADE_val_00000001.jpg" image = Image.open(requests.get(url, stream=True).raw) feature_extractor = MaskFormerFeatureExtractor.from_pretrained("facebook/maskformer-swin-small-ade") inputs = feature_extractor(images=image, return_tensors="pt")  model = MaskFormerForInstanceSegmentation.from_pretrained("facebook/maskformer-swin-small-ade") outputs = model(**inputs)
