I recently tried to upgrade my Tensorflow installation from 0.6 to 0.7.1 (Ubuntu 15.10, Python 2.7) because it is described to be compatible with more up-to-date Cuda libraries. Everything works well including the simple test from the Tensorflow getting started page. However I'm not able to use cuDNN. When running a program using cuDNN, I first get a warning
"Unable to load cuDNN DSO"
and later the program crashes with
I tensorflow/core/common_runtime/gpu/gpu_device.cc:717] Creating TensorFlow device (/gpu:0) -> (device: 0, name: GeForce GTX 980, pci bus id: 0000:01:00.0)

The files I downloaded for the Cuda Installation were
I followed the instructions on the Tensorflow getting started page with the exception of using cuDNN 7.0 instead of 6.5. $LD_LIBRARY_PATH is "/usr/local/cuda/lib64"
I have no clue why cudnnCreate is not found. Is there somebody who has successfully installed this configuration and can give me advice?
I get the same error when I forgot to set the LD_LIBRARY_PATH and CUDA_HOME environment variables:
export LD_LIBRARY_PATH="$LD_LIBRARY_PATH:/usr/local/cuda/lib64"
export CUDA_HOME=/usr/local/cuda
I am following this instructions to install TensorFlow in archlinux: https://github.com/ddigiorg/AI-TensorFlow/blob/master/install/install-TF_2016-02-27.md
It seems you need cuDNN v2 or above, which you can get by register for their Accelerated Computing Developer Program, which usually takes 2 days: https://developer.nvidia.com/accelerated-computing-developer
UPDATE: It seems you already have cuDNNv2
Ubuntu 14.04 && cudnnV5.0 && Cuda7.5
I got the some error and solve it in another way. Follow the official get-started page, I install the cudnn with these commands below, which is basically just copy those files into our cuda directory
tar xvzf cudnn-7.5-linux-x64-v5.1-ga.tgz
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 /usr/local/cuda/lib64/libcudnn*
But after doing this ,if we use ll command to show all the file in "/usr/local/cuda/lib64" and compare with the origin files
ll
it seems that those soft links has broken after copy. so I delete them and create manually, like this:
sudo rm libcudnn.so.5 libcudnn.so
sudo ln -sf libcudnn.so.5 libcudnn.so
sudo ln -sf libcudnn.so.5.1.3 libcudnn.so.5
after that, execute
sudo ldconfig /usr/local/cuda/lib64
and it finally worked!
