logging的用法
import logging
def create_logger(fp):
#打印日志的时间、日志级别名称、日志信息
logging.basicConfig(level=logging.INFO, format='%(asctime)s - %(levelname)s: %(message)s')
console_logger = logging.getLogger('ConsoleLoggoer')
file_logger = logging.getLogger('FileLogger')
#向文件输出日志信息
file_handler = logging.FileHandler(fp, mode='a', encoding='utf-8')
file_logger.addHandler(file_handler)
return console_logger, file_logger
# 创建logger
console_logger, file_logger = create_logger(os.path.join('./', 'train.log'))
file_logger.info('Args: %s' % str(123))
file_logger.info('Checkpoint path: %s' % "test")
