Quelle version de pydantic utilisez-vous ?

Quelle version de pydantic utilisez-vous ?

Bien vu ! llama-index a changé sa dépendance sur pydantic à partir de llama-index version 0.11.0 et literalai en hérite.
Je vais adapter le package aujourd'hui.

En attendant vous pouvez installer une version antérieure avec:

pip install --force-reinstall llama-index==0.10.68

Merci :)
