from langchain.embeddings import OpenAIEmbeddings

# Connect to Weaviate
client = connect_to_local(
    headers={"X-OpenAI-Api-Key": os.getenv("OPENAI_APIKEY")},
    additional_config=AdditionalConfig(
        timeout=Timeout(init=10, query=60, insert=120)
    )
)

# Initialize embeddings
embeddings = OpenAIEmbeddings(openai_api_key=os.getenv("OPENAI_APIKEY"))

# Create a Weaviate retriever
retriever = Weaviate(
    client=client,
    index_name="EmailQuery",
    text_key="beneficiary_email",
    embedding=embeddings
).as_retriever()

Description

Hi everyone,

I’ve been working on integrating Weaviate with LangChain to create a retriever for semantic search. However, I’m encountering an issue when trying to use the Weaviate class from LangChain to create a retriever. Here’s the error I’m getting:
