It's not finding CuDNN -

I tensorflow/stream_executor/dso_loader.cc:93] Couldn't open CUDA library > libcudnn.so.6.5. LD_LIBRARY_PATH: :/vol/cuda/7.0.28/lib64 I tensorflow/stream_executor/cuda/cuda_dnn.cc:1382] Unable to load cuDNN DSO

You need to have it installed. Please see the TensorFlow CUDA installation instructions

After untar the cudnn

[root@localhost cudnn]# cd include/
[root@localhost include]# mv cudnn.h /usr/local/cuda/include/
[root@localhost include]# cd ../lib64/
[root@localhost lib64]# mv * /usr/local/cuda/lib

And it is ok
