多处理中的 Python 日志记录

Question

如何将日志输出到多个进程的控制台？ 示例:

import multiprocessing, logging, multiprocessing_logging

logging.basicConfig(level=logging.INFO)
logger = logging.getLogger()
multiprocessing_logging.install_mp_handler(logger)

def worker():
    while True:
        logger.info("This is logging for TEST1")

def worker2():
    while True:
        logger.info("This is logging for TEST2")

if __name__ == '__main__':
    p1 = multiprocessing.Process(target=worker)
    p1.daemon = True
    p1.start()

    p2 = multiprocessing.Process(target=worker2)
    p2.daemon = True
    p2.start()

    p1.join()
    p2.join()

但是输出不正确:

INFO:root:This is logging for TEST1
INFO:root:This is logging for TEST2
IINFO:root:This is logging for TEST1
NFO:root:This is logging for TEST2
INFO:root:This is logging for TEST1
INFO:root:This is logging for TEST2
INFO:root:This is logging for TEST1
IINFO:root:This is logging for TEST2
NFO:root:This is logging for TEST1
IINFO:root:This is logging for TEST2
NFO:root:This is logging for TEST1

我尝试使用 multiprocessing-logging库，但没有帮助

您的(更新的)代码在这里运行良好:

INFO:root:This is logging for TEST1
INFO:root:This is logging for TEST1
INFO:root:This is logging for TEST1
INFO:root:This is logging for TEST1
INFO:root:This is logging for TEST1
INFO:root:This is logging for TEST1
INFO:root:This is logging for TEST1
INFO:root:This is logging for TEST1
INFO:root:This is logging for TEST1
INFO:root:This is logging for TEST2
INFO:root:This is logging for TEST1
INFO:root:This is logging for TEST1
INFO:root:This is logging for TEST2
INFO:root:This is logging for TEST2
INFO:root:This is logging for TEST2
INFO:root:This is logging for TEST2
INFO:root:This is logging for TEST2
INFO:root:This is logging for TEST2
INFO:root:This is logging for TEST2
INFO:root:This is logging for TEST2
INFO:root:This is logging for TEST2
INFO:root:This is logging for TEST2
INFO:root:This is logging for TEST2
INFO:root:This is logging for TEST2
INFO:root:This is logging for TEST2
INFO:root:This is logging for TEST2

如果它不适合你那么你应该 file a bug report with multiprocessing-logging .
