import numpy as np
 
arr2d = np.array([[4, 8, 2,  5], 
                  [6, 9, 7,  1], 
                  [4, 8, 2,  5],
                  [2, 0, 5, 11],
                  [6, 9, 7,  1]])
 
arr2d = np.unique(arr2d, axis=0)

print(arr2d)
 
 
 
 
 
'''
run:
 
[[ 2  0  5 11]
 [ 4  8  2  5]
 [ 6  9  7  1]]

'''
