使用的命令:iostat -x 5
可以看到 ssd的利用率已经满了。
之前在的数据集放在了 hdd上,训练结果特别慢。
所以我把它移动到了ssd上,然后训练参数用的 resume,
但是!!!!它把历史记住了,仍然不从ssd上来取数据。
配置文件的路径也换了,但它还是会去找旧的。
现在的100% 是扫描数据的100%
因数数据集15G~20G,还是比较多的。

看出路径不对了,然后from scratch开始训练,就好使了。
然而并无卵用,确实换到ssd上了,还是很差,应该是碎文件所致,哎。。。所以,深度学习级别的hello world 用plk存储文件是有道理的,为了不让他那么碎啊 =====个人理解啊。
