Hi, Were you able to solve this issue?

The answer is : We will have to use vectorstore methods only to dump into a file and retrieve it instead of using pickle

Just replaced the code 

with open(file_path, "wb") as f:
    pickle.dump(vectorstore_openai, f)

With this line vectorstore_openai.save_local("vectorstore")

And

replace this code vectorstore = pickle.load(f) with vectorstore = FAISS.load_local("vectorstore", OpenAIEmbeddings(), allow_dangerous_deserialization=True)
