codeBert dense retriever

This is a sentence-transformers model finetuned from shubharuidas/codebert-embed-base-dense-retriever. It maps sentences & paragraphs to a 768-dimensional dense vector space and can be used for semantic textual similarity, semantic search, paraphrase mining, text classification, clustering, and more.

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("anaghaj111/codebert-base-code-embed-mrl-langchain-langgraph")
# Run inference
