from __future__ import absolute_import

import logging

logging.basicConfig(level=logging.NOTSET, format='%(asctime)s - %(name)s - %(levelname)s - %(message)s')

logging.debug('This is a debug message.')
logging.info('This is an info message.')
logging.warning('This is a warning message.')
logging.error('This is an error message.')
logging.critical('This is a critical message.')

默认的 level 是 logging.WARNING,低于这个级别的就不输出了。如果需要显示低于 logging.WARNING 级别的内容,可以引入 logging.NOTSET 级别来显示。

DEBUG - 打印全部的日志。详细的信息,通常只出现在诊断问题上。

INFO - 打印 INFO、WARNING、ERROR、CRITICAL 级别的日志。确认一切按预期运行。

WARNING - 打印 WARNING、ERROR、CRITICAL 级别的日志。表明一些问题在不久的将来,这个软件还能按预期工作。

ERROR - 打印 ERROR、CRITICAL 级别的日志。更严重的问题,软件没能执行一些功能。

CRITICAL : 打印 CRITICAL 级别。一个严重的错误,表明程序本身可能无法继续运行。

RTX 5090要首发 性能要翻倍!三星展示GDDR7显存

三星在GTC上展示了专为下一代游戏GPU设计的GDDR7内存。

首次推出的GDDR7内存模块密度为16GB,每个模块容量为2GB。其速度预设为32 Gbps(PAM3),但也可以降至28 Gbps,以提高产量和初始阶段的整体性能和成本效益。

据三星表示,GDDR7内存的能效将提高20%,同时工作电压仅为1.1V,低于标准的1.2V。通过采用更新的封装材料和优化的电路设计,使得在高速运行时的发热量降低,GDDR7的热阻比GDDR6降低了70%。
