transforms compose didn't work

[lg2578]

my code is here:
https://www.kaggle.com/lezilv/monai-transforms
main code is:

#works:
loadimage=LoadImaged(keys=['image','label'])
resize=Resized(keys=['image','label'],spatial_size=(128,128,-1))
ensureCF=EnsureChannelFirstd(keys=['image','label'])
saveimg=SaveImaged(keys=['image','label'],
                   output_dir='/kaggle/working',
                   data_root_dir=root,
                   separate_folder=False,
                   output_postfix='',
                   output_ext='.nii',
                   resample=False,
                 )
nii=loadimage(files[27])

nii=ensureCF(nii)
nii=resize(nii)
print(nii['image'].shape)
nii=saveimg(nii)

#can't work,nothing saved
trans=Compose(
    LoadImaged(keys=['image','label']),
    EnsureChannelFirstd(keys=['image','label']),
    Resized(keys=['image','label'],spatial_size=(128,128,-1)),
    SaveImaged(keys=['image','label'],
               output_dir='/kaggle/working',
               data_root_dir=root,
               separate_folder=False,
               output_postfix='',
               output_ext='.nii',
               resample=False,
               ),
)
nii=trans(files[28])
print(nii['image'].shape)

only outputs spleen_44, the trans function didn't work.

Hi @lg2578, could you please add [] in the Compose?

trans=Compose([
    LoadImaged(keys=['image','label']),
    EnsureChannelFirstd(keys=['image','label']),
    Resized(keys=['image','label'],spatial_size=(128,128,-1)),
    SaveImaged(keys=['image','label'],
               output_dir='/kaggle/working',
               data_root_dir=root,
               separate_folder=False,
               output_postfix='',
               output_ext='.nii',
               resample=False,
               ),
])
