Python记录器无法使用子访问

Question

我正试图通过使用subprocess.popen调用从一个程序(program1(运行代码。程序2(被调用的程序(不显示记录器语句。在下面的示例中，program1调用program2，并为每个代码设置日志。

program1.py

import subprocess
import logging
import sys
def configure_logging(name):
logger = logging.getLogger(name)
logger.setLevel(logging.DEBUG)
formatter = logging.Formatter("%(asctime)s:%(name)s:%(message)s")
stream_handler = logging.StreamHandler()
stream_handler.setFormatter(formatter)
logger.addHandler(stream_handler)
return logger
logger = configure_logging(__name__) 
python_path = "Path/to/specific/pythonexe"
py_path = "Path/to/program2.py"    
cmd = "{} {}".format(python_path,py_path) 
logger.info("Cmd: {}".format(cmd)) 
cmd = cmd.split()        
proc = subprocess.Popen(cmd,stdout=subprocess.PIPE,stderr=subprocess.PIPE,universal_newlines=True)

program2.py

import logging
def logstuff(name):
logger = logging.getLogger(name)
logger.setLevel(logging.DEBUG)
formatter = logging.Formatter("%(asctime)s:%(name)s:%(message)s")
stream_handler = logging.StreamHandler()
stream_handler.setFormatter(formatter)
logger.addHandler(stream_handler)
return logger
def main():
logger.info("hi")
print("hi2")
if __name__ == "__main__": 
logger = logstuff(__name__)
main()

使用上面的设置程序1调用程序2，但logger.info语句没有打印出来，只有print((语句是.

我无法导入program2，因为它依赖于封装在anaconda环境中的特定python版本。

我想要的输出是将logger.info和任何后续的记录器调用打印到终端，那么我该如何实现这一点呢？

我相信你把记录器的设置搞砸了。也是子流程。Popen和stdout PIPE等对我不起作用。以下是我在当地工作的经验，希望能有所帮助。

程序1.py

import logging
import subprocess
logger = logging.getLogger(__name__)
logger.setLevel(logging.DEBUG)
formatter = logging.Formatter('%(asctime)s:%(name)s:%(message)s')
stream_handler = logging.StreamHandler()
stream_handler.setFormatter(formatter)
logger.addHandler(stream_handler)
python_path = 'python'
py_path = 'program2.py'
cmd = '{} {}'.format(python_path, py_path)
logger.info('Cmd: {}'.format(cmd))
cmd = cmd.split()
subprocess.call(cmd)

程序2.py

import logging
logger = logging.getLogger(__name__)
logger.setLevel(logging.DEBUG)
formatter = logging.Formatter('%(asctime)s:%(name)s:%(message)s')
stream_handler = logging.StreamHandler()
stream_handler.setFormatter(formatter)
logger.addHandler(stream_handler)

def main():
logger.info('hi program2 here')
if __name__ == '__main__':
main()

输出：

$ python program1.py 
2018-11-14 15:38:53,905:__main__:Cmd: python program2.py
2018-11-14 15:38:53,917:__main__:hi program2 here
