LindormAIEmbeddings | 🦜️🔗 LangChain

This will help you get started with Lindorm embedding models using LangChain.

To access Lindorm embedding models you'll need to create a Lindorm account, get AK&SK, and install the langchain-lindorm-integration integration package.

You can get you credentials in the console

import os


class Config:
    AI_LLM_ENDPOINT = os.environ.get("AI_ENDPOINT", "<AI_ENDPOINT>")
    AI_USERNAME = os.environ.get("AI_USERNAME", "root")
    AI_PWD = os.environ.get("AI_PASSWORD", "<PASSWORD>")

    AI_DEFAULT_EMBEDDING_MODEL = "bge_m3_model"  

The LangChain Lindorm integration lives in the langchain-lindorm-integration package:

%pip install -qU langchain-lindorm-integration

Note: you may need to restart the kernel to use updated packages.

Now we can instantiate our model object and generate chat completions:

from langchain_lindorm_integration import LindormAIEmbeddings

embeddings = LindormAIEmbeddings(
    endpoint=Config.AI_LLM_ENDPOINT,
    username=Config.AI_USERNAME,
    password=Config.AI_PWD,
    model_name=Config.AI_DEFAULT_EMBEDDING_MODEL,
)

Embedding models are often used in retrieval-augmented generation (RAG) flows, both as part of indexing data as well as later retrieving it. For more detailed instructions, please see our RAG tutorials.

Below, see how to index and retrieve data using the embeddings object we initialized above. In this example, we will index and retrieve a sample document in the InMemoryVectorStore.

from langchain_core.vectorstores import InMemoryVectorStore

text = "LangChain is the framework for building context-aware reasoning applications"

vectorstore = InMemoryVectorStore.from_texts(
    [text],
    embedding=embeddings,
)


retriever = vectorstore.as_retriever()


retrieved_documents = retriever.invoke("What is LangChain?")


retrieved_documents[0].page_content

'LangChain is the framework for building context-aware reasoning applications'

Under the hood, the vectorstore and retriever implementations are calling embeddings.embed_documents(...) and embeddings.embed_query(...) to create embeddings for the text(s) used in from_texts and retrieval invoke operations, respectively.

You can directly call these methods to get embeddings for your own use cases.

You can embed single texts or documents with embed_query:

single_vector = embeddings.embed_query(text)
print(str(single_vector)[:100])  

[-0.016254117712378502, -0.01154549140483141, 0.0042558759450912476, -0.011416379362344742, -0.01770

You can embed multiple texts with embed_documents:

text2 = (
    "LangGraph is a library for building stateful, multi-actor applications with LLMs"
)
two_vectors = embeddings.embed_documents([text, text2])
for vector in two_vectors:
    print(str(vector)[:100])  

[-0.016254086047410965, -0.011545476503670216, 0.0042558712884783745, -0.011416426859796047, -0.0177
[-0.07268096506595612, -3.236892371205613e-05, -0.0019329536007717252, -0.030644644051790237, -0.018
