Python:从多维numpy数组中移除随机值

import numpy as np

arr = np.array([[1, 2, 3], [4, 5, 6], [7, 8, 9]])

random_index = np.random.randint(0, arr.size)

arr = np.delete(arr, random_index)

import numpy as np

arr = np.array([[1, 2, 3], [4, 5, 6], [7, 8, 9]])
random_index = np.random.randint(0, arr.size)
arr = np.delete(arr, random_index)

print(arr)
