我有一个需要多处理的脚本。我从这个脚本中发现,多处理模块存在问题。为了测试这个理论,我复制并粘贴了
from multiprocessing import Process
def f(name):
print('hello', name)
if __name__ == '__main__':
p = Process(target=f, args=('bob',))
p.start()
p.join()
进入测试脚本并收到以下回溯
Traceback (most recent call last):

_lock = threading.RLock()
AttributeError: 'module' object has no attribute 'RLock'
另外,我在四核 ivy 桥上运行 fedora 18 64 位。为什么我会收到此回溯错误?
建议
这是我运行 RLock 时发生的情况
$ python3
>>> import threading
>>> threading.RLock()
<_thread.RLock owner=0 count=0>
>>>
