Python ProcessPoolExecutor日志记录失败？

我正在创建一个多处理程序来处理多个批次，但我的日志记录无法将批次记录到日志文件中，只记录root log.info，如何设置日志记录以正确打印到日志文件

日志将只打印这样一行“INFO:root:这是根日志记录 "

---

在windows/python2.7上运行的日志记录在每个子进程中使用不同的实例，无法写入同一文件。Apply follow fix将解决这个问题，但我认为更好的解决方案可能是使用logging.getlogger（'abc'）的单例模式

嗯，这很奇怪，我想我得到了一个不同的输出，因为unix系统。（两个日志工作正常）。看起来windows在这种情况下有不同的行为。@Taras，有没有办法在日志记录中解决这个问题？我想日志文件被某种方式阻止了，但老实说，我不知道。我花了30分钟试图让**在windows上运行，我不想继续在那个系统上做任何事情；（祝你好运，伙计！@TarasMatsyk找到了解决办法。
