问题：
在使用mmdetection做训练时出现这样的问题。

  File "./tools/train.py", line 124log_file = osp.join(cfg.work_dir, f'{timestamp}.log')^
SyntaxError: invalid syntaxFile "./tools/train.py", line 124log_file = osp.join(cfg.work_dir, f'{timestamp}.log')^
SyntaxError: invalid syntaxFile "./tools/train.py", line 124log_file = osp.join(cfg.work_dir, f'{timestamp}.log')^
SyntaxError: invalid syntaxFile "./tools/train.py", line 124log_file = osp.join(cfg.work_dir, f'{timestamp}.log')

解决方法：用python3跑啊，sh*t!
原因：python3.6之后允许format简写为f了，以下两种写法等价。

#python3.6之后的写法
logger.info(f'Config:\n{cfg.pretty_text}')#python3.6之前的写法
logger.info('Config:\n{}'.format(cfg.pretty_text))

忘了开自己的虚拟环境，直接在base下运行的，base下的环境是2.7，那可不得出错吗？！怎么回事啊你，能不能行了？！还查不到这问题，那可不得查不到吗，这么傻的问题谁会犯啊！
