I was trying to use 3D slicer software for total segmentation, and I am getting this error. Does somebody knows how to fix this error?

Failed to compute results.

Command ‘[‘C:/ProgramData/slicer.org/Slicer 5.8.1/bin/../bin\\PythonSlicer.EXE’, ‘C:\\ProgramData\\slicer.org\\Slicer 5.8.1\\lib\\Python\\Scripts\\TotalSegmentator.exe’, ‘-i’, ‘C:/Users/ra58956/AppData/Local/Temp/Slicer/\_\_SlicerTemp\_\_2025-10-24\_11+38+00.145/total-segmentator-input.nii’, ‘-o’, ‘C:/Users/ra58956/AppData/Local/Temp/Slicer/\_\_SlicerTemp\_\_2025-10-24\_11+38+00.145/segmentation’, ‘–ml’, ‘–task’, ‘total’]’ returned non-zero exit status

Hello

If possible, can you share the specs of the system you are running 3D Slicer on?

Also, the following link and the troubleshooting section are very helpful.
