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

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
