你好！我跑的V2版本的vit_b_k400_ft.sh，最终测试final_test需要20个小时，如下面所示，然后我又跑VideoMAE的final_test，发现也差不多那么久，但是我记得之前跑测试就俩小时左右啊，这是怎么回事啊，是我记错了么，修改了一下午v2版本的然后还是这样，突然找不到原因了

你有没有发现你的 data time 有点异常

data: 14.9077 (0.0002 -- 158.5454)

这个意思是你这批次数据，读取视频的时候，最短 0.0002 秒，最慢 158 秒，平均 15 秒。你自己看看你读视频为什么卡住了吧

嗯嗯嗯是的，我用一下午把每个模块都测了一下时间，代码从头到尾检查一遍，然后刚刚发布这个就去看了一下htop，然后发现是htop里面有个僵尸进程，nvidia-smi看不到就疏忽了，（太难了），然后我又跑了一下final_test就正常了（害）
