В Python для обмена данными между разными процессами с помощью multiprocessing
мы используем multiprocessing.Manager()
. Я хочу получить вывод [1,2,3,4,5,6,7,8,9,10]
в следующем коде, но получаю EOFError. Зачем? Код:
import multiprocessing
manager=multiprocessing.Manager()
final_list=manager.list()
input_list_one=[1,2,3,4,5]
input_list_two=[6,7,8,9,10]
def worker(data):
for item in data:
final_list.append(item)
process_1=multiprocessing.Process(target=worker,args=[input_list_one])
process_2=multiprocessing.Process(target=worker,args=[input_list_two])
process_1.start()
process_2.start()
process_1.join()
process_2.join()
print(final_list)
Я получаю следующую ошибку:
Process SyncManager-1:
