LangChain - Embeddings and Vector Stores

Identify the error in this code snippet:

from langchain.vectorstores import FAISS
from langchain.embeddings import OpenAIEmbeddings
embeddings = OpenAIEmbeddings()
texts = ["sample text"]
vector_store = FAISS.from_texts(texts, embeddings)
vector_store.save_local('faiss_index')
vector_store = FAISS.load_local('faiss_index')

Aload_local requires embeddings parameter

Bsave_local method does not exist

CMissing import for OpenAIEmbeddings

Dtexts should be a dictionary, not list

Step-by-Step Solution

Solution:

Step 1: Check method signatures
FAISS.load_local requires the embeddings object as a parameter to reconstruct the vector store properly.
Step 2: Identify missing argument
The code calls load_local without passing embeddings, causing an error.
Final Answer:
load_local requires embeddings parameter -> Option A
Quick Check:
load_local needs embeddings argument [OK]

Quick Trick: Always pass embeddings when loading FAISS index [OK]

Common Mistakes:

Forgetting to import OpenAIEmbeddings
Assuming save_local does not exist
Passing wrong data types for texts
