so i just reinstalled llama-index and nothing seems to work? is the documentation aligned with the latest version?

literally the first line importing

from llama_index.core import VectorStoreIndex, SimpleDirectoryReader

and i'm getting this error: ImportError: cannot import name 'VectorStoreIndex' from 'llama_index.core' (unknown location)

it might just be me being an idiot, for reference i'm using python 3.10.6 in venv, using llama-index 0.10.12
