[nnUnet tutorial] - Task001/nnUNetPlansv2.1_plans_2D.pkl not found

[hdnminh]

When I train model, I met FileNotFoundError: [Errno 2] No such file or directory root/my_nnunet/nnUNet/nnunet/preprocessed/Task001/nnUNetPlansv2.1_plans_2D.pkl

I guess that bug above takes place because error below:

AssertionError: Found unexpected labels in the training dataset. Please correct that or adjust your dataset.json accordingly

When I run !nnUNet_plan_and_preprocess -t 1 --verify_dataset_integrity

But I have no idea to solve this bug. Can you help me @FrancoisPorcher? Thanks in advance!
