# clip-ViT-B-16 | |
This is the Image & Text model [CLIP](https://arxiv.org/abs/2103.00020), which maps text and images to a shared vector space. For applications of the models, have a look in our documentation [SBERT.net - Image Search](https://www.sbert.net/examples/applications/image-search/README.html) | |
## Usage | |
After installing [sentence-transformers](https://sbert.net) (`pip install sentence-transformers`), the usage of this model is easy: | |
```python | |
from sentence_transformers import SentenceTransformer, util | |
from PIL import Image | |
#Load CLIP model | |
model = SentenceTransformer('clip-ViT-B-16') | |
#Encode an image: | |
img_emb = model.encode(Image.open('two_dogs_in_snow.jpg')) | |
#Encode text descriptions | |
text_emb = model.encode(['Two dogs in the snow', 'A cat on a table', 'A picture of London at night']) | |
#Compute cosine similarities | |
cos_scores = util.cos_sim(img_emb, text_emb) | |
print(cos_scores) | |
``` | |
See our [SBERT.net - Image Search](https://www.sbert.net/examples/applications/image-search/README.html) documentation for more examples how the model can be used for image search, zero-shot image classification, image clustering and image deduplication. | |
