## TL;DR

Fix: Collaborator logan-markewich: the v0.10 split into namespaced packages (llama-index-core + integrations) means any remnants of an old 0.9.x install - globally, outside the venv, or pulled in by another dependency - break imports. Fix in a fresh terminal: pip uninstall llama-index (remove any global install), create a fresh venv, pip install llama-index --upgrade --no-cache-dir --force-reinstall.
