Usage

Direct Usage (Sentence Transformers)

First install the Sentence Transformers library:

pip install -U sentence-transformers

Then you can load this model and run inference.

python

from sentence_transformers import SentenceTransformer

# Download from the 🤗 Hub
model = SentenceTransformer("sentence_transformers_model_id")
# Run inference
sentences = [
    'High fashion ladies wait outside a tram beside a crowd of people in the city.',
    'The women do not care what clothes they wear.',
    'The family is sitting down for dinner.',
]
embeddings = model.encode(sentences)
print(embeddings.shape)
# [3, 1024]

# Get the similarity scores for the embeddings
similarities = model.similarity(embeddings, embeddings)
print(similarities)
# tensor([[1.0000, 0.9784, 0.9795],
#         [0.9784, 1.0000, 0.9766],
#         [0.9795, 0.9766, 1.0000]])
