from transformers import CLIPProcessor, CLIPModel

model = CLIPModel.from_pretrained("ryanyip7777/pmc_vit-l-14_hf")

inputs = processor(text=["a photo of a cat", "a photo of a dog"], images=image, return_tensors="pt", padding=True)

outputs = model(**inputs)
logits_per_image = outputs.logits_per_image # this is the image-text similarity score
probs = logits_per_image.softmax(dim=1) # we can take the softmax to get the label probabilities
