After building TensorFlow from source, seeing libcudart.so and libcudnn errors

Question

I\'m building TensorFlow from source code. The build appears to succeed; however, when my TensorFlow program invokes import tensorflow, one or both of the foll

I have seen a similar error (bottom of this post), but complaining about libcudnn.so.6 instead of libcudart.so.8.0 (see a note below).

Solution:

1. Download 'cuDNN v6.0 Library for Linux':
   • Go to https://developer.nvidia.com/rdp/cudnn-download
   • Click on 'Download cuDNN v6.0 (April 27, 2017), for CUDA 8.0'
   • Then click on 'cuDNN v6.0 Library for Linux'. A file (named 'cudnn-8.0-linux-x64-v6.0.tgz') will be downloaded.
2. Follow the instructions of Alexander Yau above to install the cuDNN v6.0 library.

Note:

the Tensorflow installation instructions (as of 20/Aug/2017) require installing cuDNN v5.1, but my Tensorflow installation (following the instructions for installing in a virtualenv) required cuDNN v6.x (as indicated by the error). I don't know if it is a mistake on my side or a Tensorflow documentation one. Nevertheless, above solution worked for me.
