performance hint: av/logging.pyx:232:0: Exception check on 'log_callback' will always require the GIL to be acquired.
Possible solutions:
1. Declare 'log_callback' as 'noexcept' if you control the definition and you're sure you don't want the function to raise exceptions.
2. Use an 'int' return type on 'log_callback' to allow an error code to be returned.

ERROR: Failed to build 'av' when getting requirements to build wheel

Merci pour le rapport. Le pré-fix (Issue #6) pré-installait av>=14.0.0 en wheel, mais sans version pinnée, pip install nerfstudio continuait de backtracker jusqu'à nerfstudio 0.1.15, qui exige av==9.2.0 en pin strict — recompilation forcée, échec avec Cython 3.x sur Python 3.13 (Mac M5 Max inclus).

Fix : la commande d'installation pinne maintenant nerfstudio==1.1.5, ce qui évite tout backtracking. Corrigé dans 75bf651.

Pour appliquer le fix : mettre à jour l'app, supprimer le venv existant s'il a déjà été corrompu (rm -rf .venv_4dgs) et relancer l'installation depuis l'onglet 4DGS.
