OK, thanks

I'm sure that the path of my dataset is not wrong

The function sitk_read_row () in /utils/common.py is to read the .nii file from the hard disk, you can debug here to check whether the returned data is empty

Please check your data's shape， ensure that the image is read correctly.
I have modified the code to throw the suitable error message.
