I have a similar issue ``` RuntimeError: Exception thrown in SimpleITK ImageFileReader_Execute: [D:\a\1\sitk\Code\IO\src\sitkImageReaderBase.cxx:97](file:///D:/a/1/sitk/Code/IO/src/sitkImageReaderBase.cxx#line=96): sitk::ERROR: The file "nnUNet_raw\Dataset005_BH163test\labelsTr\nnUNet_raw\Dataset005_BH163test\labelsTr\XXXX_012.nii.gz" does not exist. ``` The part nnUNet_raw\Dataset005_BH163test\labelsTr is repeated in the filename.
