### Overview CLIP (Contrastive Language–Image Pre-training) builds on a large body of work on zero-shot transfer, natural language supervision, and multimodal learning. It learns from unfiltered, highly varied, and highly noisy data, and is intended to be used in a zero-shot manner. CLIP struggles on more abstract or systematic tasks such as counting the number of objects in an image and on more complex tasks such as predicting how close the nearest car is in a photo. The model allows people to design their own classifiers and removes the need for task-specific training data. ### Using the model For best results, use a Jupyter Notebook to interact with this dataset. #### Installation: ```python theme={null} !pip install pinecone datasets transformers ``` ### Create Index ```python theme={null} from pinecone import Pinecone, ServerlessSpec pc = Pinecone(api_key="API_KEY") # Create Index index_name = "clip-vit-base-patch32" if not pc.has_index(index_name): pc.create_index( name=index_name, dimension=512, metric="cosine", spec=ServerlessSpec( cloud='aws', region='us-east-1' ) ) index = pc.Index(index_name) ``` ### Embed & Upsert ```python theme={null} # Embed data # We'll use an example dataset of images of animals and cities: from datasets import load_dataset data = load_dataset( "jamescalam/image-text-demo", split="train" ) from transformers import CLIPProcessor, CLIPModel import torch model_id = "openai/clip-vit-base-patch32" processor = CLIPProcessor.from_pretrained(model_id) model = CLIPModel.from_pretrained(model_id) # move model to device if possible device = 'cuda' if torch.cuda.is_available() else 'cpu' model.to(device) # ClIP allows for both text and image embeddings def create_text_embeddings(text): text_embedding = processor(text=text, padding=True, images=None, return_tensors='pt').to(device) text_emb = model.get_text_features(**text_embedding) return text_emb[0] def create_image_embeddings(image): vals = processor( text=None, images=image, return_tensors='pt')['pixel_values'].to(device) image_embedding = model.get_image_features(vals) return image_embedding[0] # We will embed the images and search with text from IPython.display import Image def apply_vectorization(data): data["image_embeddings"] = create_image_embeddings(data["image"]) return data data = data.map(apply_vectorization) # add an id column for easy indexing later ids = [str(i) for i in range(0, data.num_rows)] data = data.add_column("id", ids) vectors = [] for i in range(0, data.num_rows): d = data[i] vectors.append({ "id": d["id"], "values": d["image_embeddings"], "metadata": {"caption": d["text"]} }) index.upsert( vectors=vectors, namespace="ns1" ) ``` ### Query ```python theme={null} query = "Show me a photo of a city" x = create_text_embeddings(query).tolist() results = index.query( namespace="ns1", vector=x, top_k=3, include_values=False, include_metadata=True ) print(results) def id_to_image_helper(id, data): # given id, renders the images and captions # resizes in order to speed up showing the image image = data[int(id)] print(image["text"]) return image["image"].resize((500, 500)) # view a specific result using the helper id_to_image_helper(results["matches"][0]["id"], data) ```
