老师！为何我的exe转成windows服务不能正常运行

Question

我写了一个图片处理的脚本，然后打包成exe文件，能正常运行，但是因为麻烦就想做成Winston服务，开机自启并且后台运行，可是在使用了nssm软件做成服务后，服务是开启了，但是没有正常运行，我图片都没有进行操作。想问下老师问题可能是哪里？我有用到多线程，生产者消费者模型，生产者是图片处理，消费者是移动图片，服务启动后只看到有图片处理结果，没有移动图片。。以下是主要代码：

    def save_pic(self):
        """
        保存图片
        """
        while 1:
            if self.savepath_queue.empty() == False:
                get = self.savepath_queue.get()
                if get == 1:
                    self.savepath_queue.task_done()
                else:
                    img = get[0]
                    path = get[1]

windows的服务我还没有做过，也不知道会有哪些坑，不过你这里既然说了能正常启动，你有没有试过在python一开始的时候写日志，通过日志看看是到底没有启动呢还是运行过程中出现异常了？
