我正在为代码创建日志文件,但出现以下错误:
[Tue Jun 11 17:22:59 2013] [error] [client 127.0.0.1] import mainLCF [Tue Jun 11 17:22:59 2013] [error] [client 127.0.0.1] File "/home/ai/Desktop/home/ubuntu/LCF/GA-LCF/mainLCF.py", line 10, in [Tue Jun 11 17:22:59 2013] [error] [client 127.0.0.1] logging.basicConfig(filename='genetic.log',level=logging.DEBUG,format='%(asctime)s %(message)s', datefmt='%m/%d/%Y %I:%M:%S %p') [Tue Jun 11 17:22:59 2013] [error] [client 127.0.0.1] File "/usr/lib/python2.7/logging/__init__.py", line 1528, in basicConfig [Tue Jun 11 17:22:59 2013] [error] [client 127.0.0.1] hdlr = FileHandler(filename, mode) [Tue Jun 11 17:22:59 2013] [error] [client 127.0.0.1] File "/usr/lib/python2.7/logging/__init__.py", line 901, in __init__ [Tue Jun 11 17:22:59 2013] [error] [client 127.0.0.1] StreamHandler.__init__(self, self._open()) [Tue Jun 11 17:22:59 2013] [error] [client 127.0.0.1] File "/usr/lib/python2.7/logging/__init__.py", line 924, in _open [Tue Jun 11 17:22:59 2013] [error] [client 127.0.0.1] stream = open(self.baseFilename, self.mode) [Tue Jun 11 17:22:59 2013] [error] [client 127.0.0.1] IOError: [Errno 13] Permission denied: '/genetic.log'
我已经检查了我想要创建日志的特定文件夹中的权限,但仍然出现错误。 我的代码是:(名称是 mainLCF.py)
import logging import sys logging.basicConfig(filename='genetic.log',level=logging.DEBUG,format='%(asctime)s %(message)s', datefmt='%m/%d/%Y %I:%M:%S %p') logging.debug("starting of Genetic Algorithm") sys.path.append("/home/ai/Desktop/home/ubuntu/LCF/ws_code") import blackboard from pyevolve import * def eval_func(chromosome): some function here
我的系统文件结构是:
/ home ai Desktop home ubuntu LCF ws_code GA-LCF blackboard.py main-LCF.py
我正在从 ws_code 中的另一个函数 lcf.py 调用 mainLCF.py。
最佳答案
您需要使用 logging.handlers python 模块更改日志文件路径。 就我而言,我做了以下事情:
import logging
from logging.handlers import RotatingFileHandler
import blackboard
WEBAPP_CONSTANTS = {
'LOGFILE': '/home/ai/Desktop/home/ubuntu/LCF/GA-LCF/ga.log',
}
def getWebAppConstants(constant):
return WEBAPP_CONSTANTS.get(constant, False)
LOGFILE = getWebAppConstants('LOGFILE')
log_handler = RotatingFileHandler(LOGFILE, maxBytes=1048576, backupCount=5)
log_handler.setFormatter(logging.Formatter( '%(asctime)s %(levelname)s: %(message)s ' '[in %(pathname)s:%(lineno)d]'))
applogger = logging.getLogger("GA")
applogger.setLevel(logging.DEBUG)
applogger.addHandler(log_handler)
applogger.debug("Starting of Genetic Algorithm")
from pyevolve import *
def eval_func(chromosome):
some function here
它奏效了。但是我仍然不知道为什么它早些时候试图在根目录下制作 genetic.log 的原因。
