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("blackmlengineer/occucoder-en-grande-v0")
# Run inference
sentences = [
    'Meat Wrapper',
    'Packers and Packagers, Hand',
    'Laundry and Dry-Cleaning Workers',
]
embeddings = model.encode(sentences)
print(embeddings.shape)
# [3, 512]

# Get the similarity scores for the embeddings
similarities = model.similarity(embeddings, embeddings)
print(similarities)
# tensor([[1.0000, 0.6319, 0.2463],
#         [0.6319, 1.0000, 0.2226],
#         [0.2463, 0.2226, 1.0000]])
