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("LamaDiab/STSBMiniLM-V9Data-256BATCH-SemanticEngine")
# Run inference
sentences = [
    'to - do - dahab',
    ' notebook',
    'notebook ruled glue binding soft cover 14.2 x 20.8 cm 160 sheets 80 gsm leather cover heeton no a25-835',
]
embeddings = model.encode(sentences)
print(embeddings.shape)
# [3, 384]

# Get the similarity scores for the embeddings
similarities = model.similarity(embeddings, embeddings)
print(similarities)
# tensor([[1.0000, 0.3351, 0.3300],
#         [0.3351, 1.0000, 0.7113],
#         [0.3300, 0.7113, 1.0000]])
