docker - Tensorflow应用程序卡住在Docker容器中

Question

我有一个tensorflow应用程序，可以在ubuntu 16.04中正常运行，但是当我尝试在带有nvidia-docker的tensorflow / tensorflow docker镜像中运行它时，它到了这一点然后冻结:

2017-07-12 22:06:10.917255: W

library wasn't compiled to use SSE4.1 instructions, but these are 
available on your machine and could speed up CPU computations.

由于它没有输出错误消息，所以我不知道从哪里开始。对我可能缺少的任何建议或进一步解决此问题的步骤？

我验证了我的nvidia-docker安装是否正常运行。

Answer 1

事实证明该应用程序正在运行，它似乎已冻结，因为在Docker容器中运行的python应用程序的输出往往会卡在缓冲区中，而永远不会显示在docker日志中。为了解决这个问题，我将-u传递给python-我现在可以在docker日志中看到应用程序的输出，一切都很好。
