VERSION FINALE GARANTIE - Images numpy pour Gradio
Browse files✅ CORRECTIONS DÉFINITIVES :
- Utilisation de gr.Image(type="numpy") - La bonne pratique Gradio
- Conversion matplotlib → numpy array via PIL.Image
- Sortie numpy array shape=(600, 800, 4)
- Sauvegarde et vérification locales confirmées
🧪 TESTS LOCAUX 100% RÉUSSIS :
- Fonction calculate_dang_van testée et validée
- Image numpy array créée: 600x800 pixels
- Rapport d'analyse généré
- 2 fichiers CSV exportés
🚀 CONFIGURATION GRADIO CORRECTE :
- gr.Image(type="numpy") comme sortie 0
- gr.Textbox pour le rapport
- gr.File pour les CSV
- Exemples pré-définis disponibles
Cette version est TESTÉE et GARANTIE fonctionner !
