RuntimeError: 
        An attempt has been made to start a new process before the
        current process has finished its bootstrapping phase.
        This probably means that you are not using fork to start your
        child processes and you have forgotten to use the proper idiom
        in the main module:
            if __name__ == '__main__':
                freeze_support()
        The "freeze_support()" line can be omitted if the program
        is not going to be frozen to produce an executable.

BrokenPipeError: [Errno 32] Broken pipe
错误原因：该问题的产生是由于windows下多线程的问题，和DataLoader类有关。将num_workers的数量修改为0即可。这是windows下的一个bug，现在（2020/6/22）仍未解决。
                    错误如下：RuntimeError:         An attempt has been made to start a new process before the        current process has finished its bootstrapping phase.        This probably means that you are not using fork to start your        child processes and you hav
				
本文实例讲述了Python提示[Errno 32]Broken pipe导致线程crash错误解决方法。分享给大家供大家参考。具体方法如下：
1. 错误现象
ThreadingHTTPServer 实现的 http 服务，如果客户端在服务器返回前，主动断开连接，则服务器端会报 [Errno 32] Broken pipe 错，并导致处理线程 crash.
下面先看个例子,python 版本: 2.7
复制代码 代码如下:#!/usr/bin/env python
#!coding=utf-8
import os
import time
import socket
import

报错信息
运行 pytorch 代码报错，BrokenPipeError: [Errno 32] Broken pipe，看起来和多线程有关。
