driver_cuda_cudnn

instruction for the installation of the Nvidia driver + cuda + cudnn

nvidia driver 375, cuda 8.0, cudnn v5.1 [1]

• nvidia-375 driver:
  • sudo add-apt-repository ppa:graphics-drivers/ppa
  • sudo apt-get update
  • sudo apt-get install nvidia-375
• cuda download web: https://developer.nvidia.com/cuda-toolkit-archive
  • .deb:
    • sudo dpkg -i cuda-repo-ubuntu1604-8-0-local-ga2_8.0.61-1_amd64.deb # or *-deb file
    • sudo apt-key add /var/cuda-repo-<version/Table>/7fa2af80.pub
    • sudo apt-get update
    • sudo apt-get install cuda
  • or other format, such as .run
• cudnn download web: https://developer.nvidia.com/cudnn You need an account before download.
  • tar xvf cudnn*.tgz
  • cd cuda
  • sudo cp */*.h /usr/local/cuda/include/
  • sudo cp */libcudnn* /usr/local/cuda/lib64/
  • sudo chmod a+r /usr/local/cuda/lib64/libcudnn*

cuDNN without sudo (in your home folder) [2]

• set the environment variables LD_LIBRARY_PATH, LIBRARY_PATH and CPATH to the directory extracted from the download.
• If needed, separate multiple directories with : as in the PATH environment variable.
  • export CUDNN_ROOT=/home/YourUserName/libs/cudnn
  • export LD_LIBRARY_PATH=$CUDNN_ROOT/lib64:$LD_LIBRARY_PATH
  • export CPATH=$CUDNN_ROOT/include:$CPATH
  • export LIBRARY_PATH=$CUDNN_ROOT/lib64:$LD_LIBRARY_PATH

uninstall:

• cudnn
  • if the cudnn was copied to CUDA_ROOT:
    • rm /usr/local/cuda/include/cudnn.h
    • rm /usr/local/cuda/lib64/libcudnn*
• cuda
  • /usr/local/cuda/bin/uninstallxxx
  • or sudo apt remove --purge cuda if cuda was install using .deb file.
• nvidia driver:
  • sudo apt remove --purge nvidia*

errors:

• raise RuntimeError('Could not find cudnn library (looked for v5[.1])')
  • solution: export LIBRARY_PATH=/usr/local/cuda/lib64:$LIBRARY_PATH
