Segmentation(export nrrd) Data Open python

I segmented using 3D Slicer and saved it with the nrrd extension.
I opened this saved data in Python and I get the following error:
Algorithm vtkNrrdReader returned failure for request:
I did not have a problem because I saved the dicom file as nrrd and open it in Python.
How can I solve this?

By default, segmentation is saved into a 4D nrrd file (to allow saving overlapping segments). If you nrrd reader cannot cope with that and your segments do not overlap then you can export the segmentation to labelmap and save that to nrrd file (that will be a simple 3D volume).

Oh i solve using your advice!

really Thanks!!
