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("prakrati123/nli-distilroberta-base-v2")
# Run inference
sentences = [
    'robert',
    "robert's perspective is quite unique.",
    "robert's perspective is quite unique.",
]
embeddings = model.encode(sentences)
print(embeddings.shape)
# [3, 768]

# Get the similarity scores for the embeddings
similarities = model.similarity(embeddings, embeddings)
print(similarities)
# tensor([[1.0000, 0.5093, 0.5093],
#         [0.5093, 1.0000, 1.0000],
#         [0.5093, 1.0000, 1.0000]])
