求助......16.04显卡深度学习训练到半夜自动重启

#1

帖子 q6121223 » 2019-03-16 14:19

系统Ubantu16.04,用来跑计算机视觉方面的深度学习算法,原始代码在出现重启问题前在本台电脑上已经跑过很多次都没有任何问题,但是大概从10天前,加了一些代码后开始出现训练至半夜重启的现象,一开始不以为意,结果之后每天训练都会发生重启,导致模型根本到不了收敛状态,刚开始怀疑自己加的代码存在内存泄漏导致内存问题重启,注释掉相关代码使用原始代码后,同样重启情况依然出现,奇怪的是,在出现此情况之前原始代码在这台电脑上的运行没有任何问题,结果现在也不行了。
在网上查找各种重启崩溃日志都没有找到崩溃原因,故来此请教有没有懂得大神能赐教一下!! 不胜感激 :Cry
PS:之前电脑上不存在message.log 特地去etc的rsyslog.conf下取消注释后才有的

下附wtmp崩溃记录 和相关auth.log syslog kern.log 和messages(从中挑选了16号半夜(最近一次)和15号半夜两次崩溃记录相关日志:)

多谢版主批准 and PPS:从wtmp中可以看到16号崩溃时间是16号凌晨02:35;15号是15号凌晨02:39 和我实际程序中专门写的一个记录程序崩溃时间的一个文件的时间节点基本一致。

散热做好没有?可能是温度过高导致的,毕竟现在天气也热起来了。
你那边夜间有没有什么供电检修临时停电之类的也可以问问
systemd体系下要用journalctl来看日志

多谢您的意见!! 电脑在学校的办公室,连着一个电源出来的插线板,然后有其他电脑接的也是同一个电源接出的不同插线板,这些电脑隔夜都没事,所以如果是电源的问题,应该是插线板的问题,我今晚试试接一下其他没问题的插线板,看看还会不会重启(多问一句,如果真的是电源问题,是不是日志里面无法记载相应的崩溃?就像我这些日志一样,都是崩溃后才出现的日志,崩溃时的错误并没有记录) :Sad

外部原因导致的供电中断,日志上基本不可能会有记录的。普通插线板的结构简单,我觉着出这种事的可能性也不大。买个ups来保证供电?
从更恶意的角度揣测,也可能是某个人半夜来动过电源或机器。尤其是如果你运行的东西关系到你或者别人的前途的话,就不可不防了。找保安查查监控,或者自己淘宝上买个微型摄像头来监测一下。

哈哈 应该不会是人为的,晚上走的时候办公室就锁门了,这边人本来也不多,而且这个算法本来也是别人的就是拿来试试随便跑跑,很水的,所以也不存在学术上的竞争。。and我刚才自己主动断电试了下,发现日志的显示和之前崩溃的那些日志规律很相似,所以今晚我试试把电脑接到别的地方或者把别的电脑接到我的这边试试,争取把这个电压因素早日排除,或者这个就是罪魁祸首也说不定 :Stop and多谢大佬相助呀!阿里嘎多!!

大佬,我测试过了,就昨天把这个电脑和别的电脑连同一个插线板,然后刚下午来看,我的电脑还是重启了,别的电脑都没问题,所以应该不是电压问题 :Cry 您觉得如果是内存不足导致的这样重启问题的话,日志里面会有相关记载吗,还是说和直接断电的日志结果一样?还有就是类似电脑崩溃的日志应该在什么地方看,百度的都是说log下的messages里面,可是我这边这个啥也没有,用journalctl 查看崩溃当时的日志 和syslog里面的内容一样 也是从崩溃后1分钟左右才有记录,记录的都是开机所进行的那些启动项之类的操作。。

你要不要去买个宽幅电源试下,是不是欠压(电压波动)或者老化(质量不好)导致电源输出不足,考虑到你计算量比较大,上个550W的?

我问了下师兄,这台电脑本来就是为了深度学习配的,所以电源当时就买的是比较大功率的,而且奇怪的是,半个月前跑这些深度学习项目都没问题的, 就最近突然开始半夜重启了,所以我感觉硬件方面的原因可能比较小,更多是系统或者算法代码方面的问题 :Sad

你要不要去买个宽幅电源试下,是不是欠压(电压波动)或者老化(质量不好)导致电源输出不足,考虑到你计算量比较大,上个550W的?
我问了下师兄,这台电脑本来就是为了深度学习配的,所以电源当时就买的是比较大功率的,而且奇怪的是,半个月前跑这些深度学习项目都没问题的, 就最近突然开始半夜重启了,所以我感觉硬件方面的原因可能比较小,更多是系统或者算法代码方面的问题 :Sad
你要是怀疑系统或者代码的问题,既然你代码用了老代码也不行,肯定不是代码问题,系统你这半个月更新了什么?桌面系统应该有自动更新的吧?如果是软件导致的,日志里面多少得有点痕迹,毫无征兆的重启这种事,你还是看下硬件的比较好,哦,对了,机箱如果散热不好,机器也会保护性关机,你要不要看看是不是散热器?是不是扣具松了硅脂涂厚了什么的,还有,看看电源里面的电容是不是因为高温炸了什么的,散热器什么的,都有自己适用多少TDP的,买小了短时间没问题,时间长了肯定不行,不要觉得硬件买回来装起来就不会出问题了
回复

回到 “Ubuntu 16.04 LTS”
