Ubuntu12.04配置NVIDIA cuda5.5经验帖

之前配过一遍都忘光了，现在要重新配一遍真是好难过。。。特此记录参考网站以便查阅。


=============

环境：Ubuntu 12.04+Cuda5.5


1. 判断安装环境：

The setup of CUDA development tools on a system running the appropriate version of Linux consists of a few simple steps:

  • Verify the system has a CUDA-capable GPU.
  • Verify the system has a supported version of Linux.
  • Verify the system has gcc installed.
见 官方配置手册：http://docs.nvidia.com/cuda/cuda-getting-started-guide-for-linux/index.html

2. 下载镜像：

https://developer.nvidia.com/cuda-downloads

下run好了


3. 安装必要的库

sudo apt-get install freeglut3-dev build-essential libx11-dev libxmu-devlibxi-dev libgl1-mesa-glx libglu1-mesa libglu1-mesa-dev

4. 删除已有nvidia，拉黑名单 

sudo apt-get remove --purge nvidia*sudo nano /etc/modprobe.d/blacklist.conf

blacklist.conf加入 

lacklist amd76x_edacblacklist vga16fbblacklist nouveaublacklist rivafbblacklist nvidiafbblacklist rivatv

5. Ctrl+Alt+F1, 登陆后安装 

sudo service lightdm stopchmod +x cuda_5.5.22_linux_64.runsudo ./cuda_5.5.22_linux_64.run


Cuda5.5集成了toolkit，sdk和driver, 所以安装的时候一路同意下来就好了


6. 得到以下安装结果

    Driver:   Installed
    Toolkit:  Installed In /Usr/Local/Cuda-5.0
    Samples:  Installation Failed. Missing Required Libraries.

也就是SDK安装失败，这个官方手册上也提到了解决方案。


7. 单独安装SDK

解压sdk：

sh cuda_5.5.22_linux_64.run -extract=/path/to/extract/dir/

到根目录下的 /path/to/extract/dir/去找c uda-samples_5.5.22_*******.run, 安装 

sh cuda-samples_5.5.22_*******.run


8. Path配置：

$sudo gedit etc/profile或~/.bashrc

export PATH=$PATH:/usr/local/cuda-5.5/binexport LD_LIBRARY_PATH=/usr/local/cuda-5.5/lib64:/lib

使之生效：

source /etc/profile（对应profile）或sudo ldconfig（对应bashrc）


还有一种装sdk的方法见http://askubuntu.com/questions/338907/how-to-install-cuda-5-5-under-ubuntu-12-04-lts-64-bit


9. 验证

见官网http://docs.nvidia.com/cuda/cuda-getting-started-guide-for-linux/index.html#verify-installation

正文最下方


11. 装好theano的前提下配置~/.theanorc配置GPU

sudo vim ~/.theanorc

写入

[global]

floatX = float32

device = gpu

进行测试：http://deeplearning.net/software/theano/tutorial/using_gpu.html#testing-theano-with-gpu

=============

此外附上其他配置参考：

1. theano+python模块

（Ubuntu 12.04自带python不用装，但要注意系统里很多模块依赖python，没事不要随便删！！！）
