 How to use  Here is how to use the model in PyTorch:  ``` from transformers import ViltProcessor, ViltForImageAndTextRetrieval import requests from PIL import Image  url = "http://images.cocodataset.org/val2017/000000039769.jpg" image = Image.open(requests.get(url, stream=True).raw) texts = ["An image of two cats chilling on a couch", "A football player scoring a goal"]  processor = ViltProcessor.from_pretrained("dandelin/vilt-b32-finetuned-flickr30k") model = ViltForImageAndTextRetrieval.from_pretrained("dandelin/vilt-b32-finetuned-flickr30k")
