Bắt đầu với 3d_segmentation/unetr_btcv_segmentation_3d.ipynb, xem xét các phát hiện lint xung quanh split_JSON, dice_vals và vòng lặp step, sau đó kiểm tra cell In [5] cùng input /dataset/dataset_0.json của cell đó. Chạy các kiểm tra cron notebook và thực thi để xác nhận rằng các lỗi lint và lỗi do thiếu danh sách dữ liệu đã được khắc phục.
