Langchain Embeddings

If you’re opening this Notebook on colab, you will probably need to install LlamaIndex 🦙.

!pip install llama-index

from langchain.embeddings import HuggingFaceEmbeddings
from llama_index import ServiceContext, set_global_service_context

embed_model = HuggingFaceEmbeddings(
    model_name="sentence-transformers/all-mpnet-base-v2"
)


service_context = ServiceContext.from_defaults(embed_model=embed_model)

# optionally set a global service context
set_global_service_context(service_context)
