## Usage
Similar usage to jina-clip-v1, the only difference is that it can use matryoshka embeddings, through the truncate_dim argument on the encode_text and encode_image features
```python
!pip install transformers einops timm pillow
from transformers import AutoModel

# Initialize the model
model = AutoModel.from_pretrained('jinaai/jina-clip-v2-test', trust_remote_code=True)

# New meaningful sentences
sentences = ['A blue cat', 'A red cat']

# Public image URLs
image_urls = [
    'https://i.pinimg.com/600x315/21/48/7e/21487e8e0970dd366dafaed6ab25d8d8.jpg',
    'https://i.pinimg.com/736x/c9/f2/3e/c9f23e212529f13f19bad5602d84b78b.jpg'
]

# Encode text and images
truncate = 512
text_embeddings = model.encode_text(sentences, truncate_dim = truncate)
image_embeddings = model.encode_image(image_urls, truncate_dim = truncate)  # also accepts PIL.image, local filenames, dataURI

# Compute similarities
print(text_embeddings[0] @ text_embeddings[1].T) # text embedding similarity
print(text_embeddings[0] @ image_embeddings[0].T) # text-image cross-modal similarity
print(text_embeddings[0] @ image_embeddings[1].T) # text-image cross-modal similarity
print(text_embeddings[1] @ image_embeddings[0].T) # text-image cross-modal similarity
print(text_embeddings[1] @ image_embeddings[1].T)# text-image cross-modal similarity
```
