How can I resolve the unexpected 'token' keyword error in HuggingFaceInstructEmbeddings?

I'm deploying a RAG system and encountering the following error when trying to initialize HuggingFaceInstructEmbeddings:
PYTHONTraceback (most recent call last): File "...", line ..., in <module> ... TypeError: INSTRUCTOR._load_sbert_model() got an unexpected keyword argument 'token'
This error occurs in the following context within my function:
PYTHONdef create_or_get_vector_store(chunks: list) -> FAISS: """ Funzione per creare o caricare il database vettoriale dalla memoria locale. Returns: FAISS: Vector store """ # Automatically choose device: CUDA if available, otherwise CPU device = 'cuda' if torch.cuda.is_available() else 'cpu' # Initialize HuggingFaceInstructEmbeddings with the chosen device embeddings = HuggingFaceInstructEmbeddings( query_instruction="Represent the query for retrieval: ", model_name="hkunlp/instructor-large", # Example model name model_kwargs={'device': device}, encode_kwargs={'normalize_embeddings': True} # Optional: to normalize the embeddings ) # Check if the vector store exists; if not, create it if not os.path.exists("./db"): print("CREATING DB") # Create the FAISS vector store from the documents (chunks) vectorstore = FAISS.from_documents(chunks, embeddings) # Save the vector store locally vectorstore.save_local("./db") else: print("LOADING DB") # Load the pre-existing vector store vectorstore = FAISS.load_local("./db", embeddings) return vectorstore
I suspect this error is related to a version mismatch between LangChain’s community integrations and the underlying sentence-transformers library, with an unexpected keyword being passed (i.e., 'token').
I have verified that I am not explicitly supplying a 'token' parameter, and I plan to check the following:
Has anyone encountered this error before or have suggestions on how to resolve this keyword conflict? Any help would be appreciated!

The error
TypeError: INSTRUCTOR._load_sbert_model() got an unexpected keyword argument 'token'
usually indicates a version mismatch or unexpected keyword being passed to the underlying SentenceTransformer model loader. In this case, the HuggingFaceInstructEmbeddings is likely passing a parameter (in this context “token”) that your currently installed sentence-transformers (or its dependencies) does not expect.
Below are some steps to troubleshoot and resolve the issue:
Check Your Package Versions:
Ensure that you are using versions of both langchain (and its community integrations) and sentence-transformers that are compatible. For instance, recent changes in sentence-transformers may have dropped or renamed some keyword arguments. You might try downgrading sentence-transformers to a version (e.g. 2.2.2) that is known to work with LangChain’s HuggingFaceInstructEmbeddings.
BASHpip install sentence-transformers==2.2.2
Update LangChain Community Packages:
It’s also possible that an update in the LangChain community repository has fixed this mismatch. Verify that you have the latest version of langchain-community packages installed.
BASHpip install -qU langchain-community
Review Any Additional Keyword Arguments:
In your function you are passing model_kwargs={'device': device}
and encode_kwargs={'normalize_embeddings': True}
to HuggingFaceInstructEmbeddings. Confirm you are not inadvertently supplying a token
keyword anywhere (or via environment variables) that the model loader might be picking up.
Consult the Repository or Issue Tracker:
Since this issue is related to how the underlying model is loaded, checking the GitHub issues for the langchain community embeddings or sentence-transformers may provide guidance if others have encountered the same error.
By ensuring that your package versions are aligned and that no unexpected keyword arguments (like “token”) are being injected, you should be able to resolve the error and successfully build or load your FAISS vector store.
