我正在尝试使用流程为生产者消费者编写简单的代码。生产者是一个过程。对于消费者,我正在从池中获取进程。
from multiprocessing import Manager, Process, Pool
from time import sleep
def writer(queue):
for i in range(10):
queue.put(i)
print 'put 1 size now ',queue.qsize()
sleep(1)
def reader(queue):
print 'in reader'
for i in range(10):
queue.get(1)
print 'got 1 size now ', queue.qsize()
if __name__ == '__main__':
q = Manager().Queue()
p = Process(target=writer, args=(q,))
p.start()
pool = Pool()
c = pool.apply_async(reader,q)
但我得到错误,
Process Process-2:
Traceback (most recent call last):
File "/usr/lib/python2.7/multiprocessing/process.py", line 258, in _bootstrap
self.run()
File "/usr/lib/python2.7/multiprocessing/process.py", line 114, in run
self._target(*self._args, **self._kwargs)
File "pc.py", line 5, in writer
queue.put(i)
File "<string>", line 2, in put
File "/usr/lib/python2.7/multiprocessing/managers.py", line 758, in _callmethod
conn.send((self._id, methodname, args, kwds))
IOError: [Errno 32] Broken pipe
谁能指出我,我哪里错了。
