I followed the instructions of the official pytorch implementation, but I got error when executing

"for FOLD in 0 1 2 3 4
do
nnUNet_train 3d_fullres nnUNetPlusPlusTrainerV2 Task003_Liver $FOLD
done"

The error is as fllows:PermissionError:

I use virtual machine of ubuntu system and want to run official code of official data.
I don't know if I should create the three files /nnUNet_raw_data_base/nnUNet_preprocessed/nnUNet_trained_models and put the data in it. Because I don't find where is the training data.
Thanks
