(Python多处理)如何访问与multiprocessing.shared_memory.SharedMemory共享的数组？

import multiprocessing.shared_memory as shm

# 创建共享内存并分配给一个整数数组
shared_memory = shm.SharedMemory(create=True, size=10 * sizeof(c_int))
array = np.ndarray((10,), dtype=np.int32, buffer=shared_memory.buf)

import multiprocessing.shared_memory as shm

# 获取共享内存的名称
shared_memory = shm.SharedMemory(name='my_shared_memory')

import multiprocessing.shared_memory as shm
import numpy as np

# 打开共享内存并分配给一个数组
shared_memory = shm.SharedMemory(name='my_shared_memory')
array = np.ndarray((10,), dtype=np.int32, buffer=shared_memory.buf)

# 访问和修改数组
array[0] = 1
value = array[0]
