 首先明确，这是make runtest的错误，因此必定不能是代码问题。必定是个人配置问题。虽然是segnet做者改得caffe，可是应该没有问题。不过我仍是打算用官方的caffe跑一下试试。

我以前那篇教程，安装教程http://www.cnblogs.com/SweetBeens/p/8525131.html，提到若是ubuntu16.04装9,可能会有问题，那么问题来了。官网给出的doc提到了这个问题：

The GPU program failed to execute. This is often caused by a launch failure of the kernel on the GPU, which can be caused by multiple reasons.

To correct: check that the hardware, an appropriate version of the driver, and the cuBLAS library are correctly installed.

github上有个比较火的讨论贴：

https://github.com/BVLC/caffe/issues/2417

你们的解决方法是装cuda8.0,还有说不用cudnn。

但因为我不到黄河心不死，不想用cuda8

那么有以下思路：

1,跑官网caffe，看看是否是由于segnet_caffe版本过低或者什么的

2.改下gcc版本

3.更换driver和cuda版本

等我试试。并且为何别人的有一些可用16.04+9.1，奇怪了。

拟解决过程

1.我跑了官网的caffe，出现以下错误：

 问题解决

cuda版本问题。在个人电脑配置环境下，必须是ubuntu 16.04+cuda8。不能够用9.1.

那么借鉴这个思路，请各位看下本身的版本有没有不按要求整的。基本限制就是cuda，python。

我简化的安装步骤，更方便查漏补缺：

详细的安装版本制约:

以及利用anaconda2随意配置多个版本：

卸载cuda9.1安装cuda8
