3D Image visualisation with nilearn

Question

I used plot_glass_brain to visualize 3D image (Nifti) with nilearn but it is displayed incorrectly. see code and pictures below

The 2_1_t2.nii file is available on this link : https://drive.google.com/file/d/1_gsg8sO9c7Ws6Xd7xB1uFSW8H31tAHtm/view?usp=sharing

import matplotlib.pyplot as plt
from nilearn.plotting import plot_anat, show
plotting.plot_glass_brain('2_1_t2.nii')
plotting.show()
