废话不多说了，直接上代码吧！

import numpy as np
 
array = np.array([0, 0])
for i in range(10):
  array = np.vstack((array, [i+1, i+1]))
print(array)
# [[ 0 0]
# [ 1 1]
# [ 2 2]
# [ 3 3]
# [ 4 4]
# [ 5 5]
# [ 6 6]
# [ 7 7]
# [ 8 8]
# [ 9 9]
# [10 10]]
 
rand_arr = np.arange(array.shape[0])
 
np.random.shuffle(rand_arr)
print(array[rand_arr[0:5]])
# [[9 9]
# [4 4]
# [1 1]
# [5 5]
# [8 8]]
np.random.shuffle(rand_arr)
print(array[rand_arr[0:5]])
# [[10 10]
# [ 3 3]
# [ 4 4]
# [ 8 8]
# [ 5 5]]
