对象的多处理？

Question

给定以下代码：

if __name__ == '__main__':
    print "name = main"
    multiprocessing.Process(target=r.fetchFiles, args=(r.results.pop(),))

class R:
    # ...
    def fetchFiles(self, blabla):
        with open('/tmp/doyou.txt', 'w+') as f:
            f.write('do you do something?')

r 是 R 的实例。测试文件没有被写入。为什么？

Answer 1

进程需要started:

process = multiprocessing.Process(target=r.fetchFiles, args=(r.results.pop(),))
process.start()
process.join()

一个简单的工作示例：

from multiprocessing import Process

class R:
    def print_value(self, value):
        print(value)

if __name__ == '__main__':
    process = Process(target=R().print_value, args=('a',))
    process.start()
    process.join()
