Cuda and cudnn install. Where is cudnn_samples_v7?

  • 772

I am follow this to install cuda and cudnn http://docs.nvidia.com/deeplearning/sdk/cudnn-install/index.html

Does the below output mean that cuda is already properly installed ? What other code must i type to check if cuda has been properly installed ?

usr@usr-P15SM:~$ ldconfig -p | grep cuda
libicudata.so.55 (libc6,x86-64) => /usr/lib/x86_64-linux-gnu/libicudata.so.55

libcudart.so (libc6,x86-64) => /usr/lib/x86_64-linux-gnu/libcudart.so

nvcc: NVIDIA (R) Cuda compiler driver
Copyright (c) 2005-2015 NVIDIA Corporation

Cuda compilation tools, release 7.5, V7.5.17

But when i go to this step http://docs.nvidia.com/deeplearning/sdk/cudnn-install/index.html#verify,

To verify that cuDNN is installed and is running properly, compile the mnistCUDNN sample located in the /usr/src/cudnn_samples_v7 directory in the debian file.

but i cannot find /usr/src/cudnn_samples_v7 ? Help please easy question free points.

  1. You need to download a separate file cuDNN v7.1.3 Code Samples and User Guide for Ubuntu16.04 (Deb) from the same page where you got CuDNN files, and install it with dpkg.

  2. You dont need to go to < /usr/src/cudnn_samples_v7> to ensure the installation if you installed the cuDNN with .tgz file.

    You can ensure the installation by following:

    cat /usr/local/cuda/include/cudnn.h | grep CUDNN_MAJOR -A 2

    It will show the following O/P

    CUDNN_MAJOR -A 2
#define CUDNN_MAJOR 7
#define CUDNN_MINOR 6
#define CUDNN_PATCHLEVEL 5
--
#define CUDNN_VERSION (CUDNN_MAJOR * 1000 + CUDNN_MINOR * 100 + CUDNN_PATCHLEVEL)

#include "driver_types.h"

  3. Nvidia SDK doc:

    2.3.2. Installing from a Debian File

    1. Install the code samples and the cuDNN Library User Guide, for example: sudo dpkg -i libcudnn7-doc_7.0.3.11-1+cuda9.0_amd64.deb

    You need to download the deb file and install the code samples with the above code.
