import numpy as np
arra = np.array([[ 1, 1, 0],
[ 0, 0, 0],
[ 0, 2, 3],
[ 0, 0, 0],
[ 0, -1, 1],
[ 0, 0, 0]])
print("Original array:")
print(arra)
temp = {(0, 0, 0)}
result = []
for idx, row in enumerate(map(tuple, arra)):
if row not in temp:
result.append(idx)
print("\nNon-zero unique rows:")
print(arra[result])Sample Output:
Original array: [[ 1 1 0] [ 0 0 0] [ 0 2 3] [ 0 0 0] [ 0 -1 1] [ 0 0 0]] Non-zero unique rows: [[ 1 1 0] [ 0 2 3] [ 0 -1 1]]
