Hi @ahujaravinder022 The issue you're facing is most likely related to faiss or the embeddings you are passing. Ensure that the library is installed correctly using either: pip install faiss-cpu
pip install faiss-gpu

There might also be an issue with the embeddings array. You can check this by printing the shape of the embeddings with: print("Embedding shape:", len(embeddings), len(embeddings[0]) if embeddings else "Empty embeddings") It will help you identify if the embeddings array is empty or has inconsistent dimensions."
