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.

from sentence_transformers import SentenceTransformer

# Download from the 🤗 Hub
model = SentenceTransformer("sentence_transformers_model_id")
# Run inference
sentences = [
    'A Little League team tries to catch a runner sliding into a base in an afternoon game.',
    'A team is playing baseball on Saturn.',
    'a woman eating a banana crosses a street',
]
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, 0.9826, 0.8269],
#         [0.9826, 1.0000, 0.8012],
#         [0.8269, 0.8012, 1.0000]])
