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 = [
    'The school is having a special event in order to show the american culture on how other cultures are dealt with in parties.',
    'A school is hosting an event.',
    'A married couple is walking next to each other.',
]
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, 0.9874, 0.9852],
#         [0.9874, 1.0000, 0.9922],
#         [0.9852, 0.9922, 1.0000]])
