日志文件中的matplotlib.font_manager调试消息

我想在日志文件中记录优化进度,但是我的日志文件中填充了matplotlib字体管理器中的内容,例如:

DEBUG:matplotlib.font_manager:findfont: Matching :family=sans-serif:style=normal:variant=normal:weight=normal:stretch=normal:size=10.0.)
DEBUG:matplotlib.font_manager:findfont: score(<Font 'STIXSizeThreeSym' (STIXSizThreeSymBol.ttf) normal normal bold normal>) = 10.335)
DEBUG:matplotlib.font_manager:findfont: score(<Font 'cmmi10' (cmmi10.ttf) normal normal 400 normal>) = 10.05)
DEBUG:matplotlib.font_manager:findfont: score(<Font 'STIXSizeTwoSym' (STIXSizTwoSymReg.ttf) normal normal regular normal>) = 10.05)
DEBUG:matplotlib.font_manager:findfont: score(<Font 'cmsy10' (cmsy10.ttf) normal normal 400 normal>) = 10.05)
DEBUG:matplotlib.font_manager:findfont: score(<Font 'DejaVu Sans' (DejaVuSans-BoldOblique.ttf) oblique normal bold normal>) = 1.335)
DEBUG:matplotlib.font_manager:findfont: score(<Font 'DejaVu Sans Mono' (DejaVuSansMono-BoldOblique.ttf) oblique normal bold normal>) = 11.335)
DEBUG:matplotlib.font_manager:findfont: score(<Font 'STIXSizeOneSym' (STIXSizOneSymReg.ttf) normal normal regular normal>) = 10.05)
DEBUG:matplotlib.font_manager:findfont: score(<Font 'DejaVu Sans Mono' (DejaVuSansMono.ttf) normal normal 400 normal>) = 10.05)
DEBUG:matplotlib.font_manager:findfont: score(<Font 'DejaVu Sans' (DejaVuSans-Bold.ttf) normal normal bold normal>) = 0.33499999999999996)
DEBUG:matplotlib.font_manager:findfont: score(<Font 'DejaVu Sans Mono' (DejaVuSansMono-Bold.ttf) normal normal bold normal>) = 10.335)

我正在使用记录器,如下所示:

import logging

logger=logging.getLogger(__name__)

logging.basicConfig(filename='logfile.log',level=logging.DEBUG,
                    format='%(levelname)s:%(name)s:%(message)s)')

def objective(x):

    obj=model(x)
    logger.debug('objective = {}'.format(obj))

    return obj

如何防止matplotlib破坏整个日志文件?

答案 0 :(得分:2)

解决方案由tomjn提供:

level=logging.DEBUG中的

basicConfig已删除,并位于logger.setLevel(logging.DEBUG)下面的行中 加入。这样就可以

logger = logging.getLogger(__name__)
logger.setLevel(logging.DEBUG)
