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.7.5 (libc6,x86-64) => /usr/lib/x86_64-linux-gnu/libcudart.so.7.5
libcudart.so (libc6,x86-64) => /usr/lib/x86_64-linux-gnu/libcudart.so
libcuda.so.1 (libc6,x86-64) => /usr/lib/x86_64-linux-gnu/libcuda.so.1
libcuda.so.1 (libc6) => /usr/lib/i386-linux-gnu/libcuda.so.1
libcuda.so (libc6,x86-64) => /usr/lib/x86_64-linux-gnu/libcuda.so
libcuda.so (libc6) => /usr/lib/i386-linux-gnu/libcuda.so

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.


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.


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.
