Ubuntu 12.04配置NVIDIA CUDA5.5實錄

現在重新在Ubuntu 12.04下配置NVIDIA CUDA5.5，特此記錄參考網站以便查閱。

環境：Ubuntu 12.04+Cuda5.5

1. 判斷安裝環境：

• 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.

見官方配置手冊：http://docs.nvidia.com/cuda/cuda-getting-started-guide-for-linux/index.html

2. 下載鏡像：

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

下run好了

3. 安裝必要的庫

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

4. 刪除已有nvidia，拉黑名單

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

blacklist.conf加入

lacklist amd76x_edac
blacklist vga16fb
blacklist nouveau
blacklist rivafb
blacklist nvidiafb
blacklist rivatv

5. Ctrl+Alt+F1, 登陸後安裝

sudo service lightdm stop
chmod +x cuda_5.5.22_linux_64.run
sudo ./cuda_5.5.22_linux_64.run

Cuda5.5集成了toolkit，sdk和driver, 所以安裝的時候一路同意下來就好了

6. 得到以下安裝結果

Driver: Installed

Toolkit: Installed In /Usr/Local/Cuda-5.0

Samples: Installation Failed. Missing Required Libraries.

也就是SDK安裝失敗，這個官方手冊上也提到了解決方案。

7. 單獨安裝SDK

解壓sdk：

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

到根目錄下的/path/to/extract/dir/去找cuda-samples_5.5.22_*******.run, 安裝

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/bin
export LD_LIBRARY_PATH=/usr/local/cuda-5.5/lib64:/lib

使之生效：

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

還有一種裝sdk的方法見http://askubuntu.com/questions/338907/how-to-install-cuda-5-5-under-ubuntu-12-04-lts-64-bit

9. 驗證

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

nvcc-V:

deviceQuery:

10. Cuda Hello World:

正文最下方

11. 裝好theano的前提下配置~/.theanorc配置GPU

sudo vim ~/.theanorc

寫入

[global]

floatX = float32

device = gpu

進行測試：http://deeplearning.net/software/theano/tutorial/using_gpu.html#testing-theano-with-gpu

此外附上其他配置參考：

1. theano+python模塊

（Ubuntu 12.04自帶python不用裝，但要注意系統裡很多模塊依賴python，沒事不要隨便刪！！！） http://www.linuxidc.com/Linux/2014-10/107503.htm
