Chromadb + Langchain + SentenceTransformerEmbeddingFunction throwing 'SentenceTransformerEmbeddingFunction' object has no attribute 'embed_documents'

Question

I have been trying to use

• Chromadb version 0.4.8
• Langchain version 0.0.276

with SentenceTransformerEmbeddingFunction as shown in the snippet below.

from langchain.vectorstores import Chroma
from chromadb.utils import embedding_functions

# other imports
embedding = embedding_functions.SentenceTransformerEmbeddingFunction(model_name="all-MiniLM-L6-v2")

However, it throws the following error.

AttributeError: 'SentenceTransformerEmbeddingFunction' object has no attribute 'embed_documents'

Would appreciate any help. Thank you.

Your error irrelevant with code that you provided. I am on same versions with you but this works for me, maybe your usage of embedding variable can cause this error.

Can you please provide full code.
