Commencez par 3d_segmentation/unetr_btcv_segmentation_3d.ipynb, examinez les problèmes de lint autour de split_JSON, dice_vals et de la boucle d’étapes, puis inspectez la cellule In [5] et son entrée /dataset/dataset_0.json. Exécutez les vérifications du notebook cron et l’exécution afin de confirmer que les erreurs de lint et l’échec dû à l’absence de la liste de données sont résolus.
