How can I create .nii (nifti) file from 3D Numpy array

Question

I have a prediction numpy array. How can I make a .nii or .nii.gz mask file from the array?

The [`nibabel` python package](https://nipy.org/nibabel/) might be able to help you with this. — Oxbowerce, Mar 16 '21 at 15:53

You can this using nibabel:

import nibabel as nb

ni_img = nib.Nifti1Image(numpy_array, affine=np.eye(4))
nib.save(ni_img, "dicom_volume_image.nii")
