如何通过轴使我的numpy数组唯一？

import numpy as np

# 创建一个示例数组
arr = np.array([1, 2, 2, 3, 4, 4, 5])

# 使用numpy.unique获取唯一值
unique_arr = np.unique(arr)

print(unique_arr)

[1 2 3 4 5]

import numpy as np

# 创建一个二维数组
arr = np.array([[1, 2, 3], [1, 2, 3], [4, 5, 6]])

# 沿着轴0获取唯一值
unique_arr_axis0 = np.unique(arr, axis=0)

# 沿着轴1获取唯一值
unique_arr_axis1 = np.unique(arr, axis=1)

print("Unique along axis 0:\n", unique_arr_axis0)
print("Unique along axis 1:\n", unique_arr_axis1)

Unique along axis 0:
 [[1 2 3]
 [4 5 6]]
Unique along axis 1:
 [[1 2 3]
 [1 2 3]
 [4 5 6]]
