OSError: [Errno 4] Interrupted system call

######
加载数据出错：
/usr/lib/python2.7/multiprocessing/reduction.py", line 157, in rebuild_handle
    new_handle = recv_handle(conn)
  File "/usr/lib/python2.7/multiprocessing/reduction.py", line 83, in recv_handle
    return _multiprocessing.recvfd(conn.fileno())
OSError: [Errno 4] Interrupted system call
Exception socket.error: error(111, 'Connection refused') in <bound method DataLoaderIter.__del__ of <torch.utils.data.dataloader.DataLoaderIter object at 0x7f94f55bfc90>> ignored

######
解决方法：

打开文件
"/usr/lib/python2.7/multiprocessing/reduction.py"

把82行的函数recv_handle() 
#####
def recv_handle(conn):
    return _multiprocessing.recvfd(conn.fileno())
#####

改为如下内容
#####
def recv_handle(conn):
    while True:
        try:
            _fl_data = _multiprocessing.recvfd(conn.fileno())
            break
        except OSError, num:
            print num
            if num==4:
                continue
    return _fl_data
