我开发了一个 GitHub 存储库，其中包含python2.7 中用于绘图的多进程脚本示例。基本上，脚本分配一个进程来生成数据，这些数据通过队列传递到负责生成绘图的第二个进程。当我同时运行示例“multiproc_processIPC.py”或“multiproc_poolQ​​UEUE.py”时，我收到以下错误。请注意，在将我的 mac 升级到 OSX Sierra 之后出现此错误。有人知道这个问题的根源吗？任何帮助将不胜感激

尝试将“start method”设置为“spawn”而不是默认的“fork”。有关详细信息，请参阅https://docs.python.org/3/library/multiprocessing.html#contexts-and-start-methods。

这对我有类似的问题。

好的，更多信息：如果我从终端运行第一个进程，其脚本“visl.py”是：

#!/usr/bin/env python
from multiprocessing import Process
import sys
sys.path.insert(0, './lib')
import visualizer

visualizer.Visualizer()

然后是来自不同终端实例的第二个进程，其脚本“logr.py”是：

#!/usr/bin/env python
from multiprocessing import Process
import sys
sys.path.insert(0, './lib')
import logger


args_logger = {'sampling_time_ms': 5, 'plotting_time_ms': 100}
logger.Logger(args_logger)

有用。然后：如何从一个脚本运行两个 python 进程？
