Ubuntu安裝Nvida Driver與CUDA

    關閉UEFI secure boot

    現在比較新一點的主板預設可能會用UEFI secure boot,若沒有的話可以忽略這步驟。UEFI secure boot 會讓3rd party driver包括NVidia失效,所以最好關閉它,最簡單的作法就是到bios去設定,具體方式因bios而異。

    NVidia Driver

    優先透過apt-get安裝distribution-specific的驅動

    sudo add-apt-repository ppa:graphics-drivers/ppa
    sudo apt-get update
    sudo apt-get install build-essential nvidia-375
    

    如果行不通,再到官網去下載runfile安裝

    驗證:

    $ nvidia-smi

    CUDA

    官網提供兩種安裝方法,建議用.deb安裝,因為runfile安裝需要關閉x-server,比較麻煩。

    安裝完之後,在.bashrc新增

    export CUDA_HOME=/usr/local/cuda-8.0 
    export LD_LIBRARY_PATH=${CUDA_HOME}/lib64 
    PATH=${CUDA_HOME}/bin:${PATH} 
    export PATH
    

    然後重開機

    驗證安裝:

    cd $CUDA_HOME
    cd samples/1_Utilities/deviceQuery
    sudo make
    ./deviceQuery
    

    結果

    /usr/local/cuda-8.0/samples/1_Utilities/deviceQuery/deviceQuery Starting...

    可以看到CUDA Capability Major是6.1,等等安裝tensorflow會用到。CUDA samples裡面還有許多有趣的範例,建議玩玩看。

    cuDNN

    下載官方cuDNN包,並複製到cuda資料夾

    (未必正確)
    $ cd folder/extracted/contents
    $ sudo cp -P include/cudnn.h /usr/include
    $ sudo cp -P lib64/libcudnn* /usr/lib/x86_64-linux-gnu/
    $ sudo chmod a+r /usr/lib/x86_64-linux-gnu/libcudnn*

    安裝tensorflow

    按照官網指示,介紹得很詳盡,基本沒啥問題。其中configure時的問與答,enable cuda選y,device compute capability填上剛剛deviceQuery查到的數值,其餘可用預設。
