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 came across the same issue

Failed to load the native TensorFlow runtime.

I have installed cudnn 6.0 while it needs libcudnn.so.5, apparently it couldn't find libcudnn.so.5. It seems that your tensorflow needs cudnn 5.x, so install cudnn 5.x

Make sure you have already installed cuda 8.0 and exported the PATH and LD_LIBRARY_PATH

To install cudnn 5.x, try the following commands

Extract tgz files

$ tar -zxvf cudnn-8.0-linux-x64-v5.1.tgz

Check the files

$ cd cuda/lib64/
$ ls -l
total 150908
lrwxrwxrwx 1 doom doom       13 Nov  7  2016 libcudnn.so -> libcudnn.so.5
lrwxrwxrwx 1 doom doom       18 Nov  7  2016 libcudnn.so.5 -> libcudnn.so.5.1.10
-rwxr-xr-x 1 doom doom 84163560 Nov  7  2016 libcudnn.so.5.1.10
-rw-r--r-- 1 doom doom 70364814 Nov  7  2016 libcudnn_static.a

Here you will see 2 symbolic link files, and just copy libcudnn.so.5.1.10 and libcudnn_static.a to /usr/local/cuda/lib64

Make symbolic link files

$ cd /usr/local/cuda/lib64/
$ sudo ln -s libcudnn.so.5.1.10 libcudnn.so.5
$ sudo ln -s libcudnn.so.5 libcudnn.so
$ ls -l libcudnn*
lrwxrwxrwx 1 root root       13 May 24 09:24 libcudnn.so -> libcudnn.so.5
lrwxrwxrwx 1 root root       18 May 24 09:24 libcudnn.so.5 -> libcudnn.so.5.1.10
-rwxr-xr-x 1 root root 84163560 May 24 09:23 libcudnn.so.5.1.10
-rw-r--r-- 1 root root 70364814 May 24 09:23 libcudnn_static.a

Copy cudnn.h in include directory to /usr/local/cuda/include

$ sudo cp cudnn.h /usr/local/cuda/include/

Hope it will help you!
