Import error after installing tensorflow

Question

I tried installing tensorflow as given in the link Installing Tensor flow

I installed it inside virtual environment. I am getting import error as given at the end in edit.

I've set the following environment variables.

PATH=/usr/local/cuda-8.0/bin:rest/of/the/path
LD_LIBARY_PATH=/home/harshit/Drivers/cudnn5.0/cuda/:/usr/local/cuda-8.0/lib64/:/usr/local/cuda/lib64/

Moreover, I also tried manually copying the files of cudnn but still no luck. That is, I have libcudnn.so.5 in both /usr/local/cuda/lib64 and /usr/local/cuda-8.0/lib64 .

As given in other related posts, problem is usually due to environment paths but I feel they are quite correct in my case, but still error persists.

Please help!

Edit- Here is the complete error traceback-

I think your libcudnn.so files are not linked correctly.

Please do

$ sudo ldconfig

This will show you the files in /path/to/cuda-8.0/lib64 that are not linked properly. These should be libcudnn.so and libcudnn.so.5 (as per your error).

Try to attempt the following commands on your terminal: If you have cudnn v6 (like I have):

$ cd /path/to/cuda-8.0/lib64

Please remove libcudnn.so.6 and libcudnn.so from this folder if you have copied these manually from the NVIDIA CUDNN package.

$ sudo ln -s libcudnn.so.6.0.21 libcudnn.so.6
$ sudo ln -s libcudnn.so.6 libcudnn.so
$ sudo ldconfig

Please change the file names according to the version of cudnn you are using.
