How to install cuDNN

cuDNN provides primitives for deep learning networks that have been accelerated for GPUs by NVIDIA.

• To download cuDNN head over to the cuDNN page here. cuDNN is not directly available for download. NVIDIA requires you to create a login. After that it presents cuDNN downloads in different formats (.tgz or .deb).

• I prefer to install from .tgz since it gives more control. Unzip the file and it will create a cuda directory which has the required include and lib directories.

• Copy the files over to your CUDA directory:

$ sudo cp cuda/include/cudnn.h /usr/local/cuda-X.Y/include
$ sudo cp cuda/lib64/libcudnn* /usr/local/cuda-X.Y/lib64
$ sudo chmod a+r /usr/local/cuda-X.Y/include/cudnn.h
$ sudo chmod a+r /usr/local/cuda-X.Y/lib64/libcudnn*

Replace cuda-X.Y with the specific CUDA version directory on your system.

That is it! Caffe and other projects needing cuDNN should be able to find and link with cuDNN now.

Tried with: cuDNN 6.0 and Ubuntu 16.04
