Tensorflow: ImportError: libcusolver.so.8.0: cannot open shared object file: No such file or directory

Found the solution:

I reinstalled nvidia-381, CUDA-8.0 (using the runfile) and cuDNN 6.0. Then I added the following in my .bashrc:

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/cuda/lib64/

No need for reinstallation. Install nvidia-cuda-dev:

sudo apt install nvidia-cuda-dev

Install cuDNN (which you download from https://developer.nvidia.com/cudnn), and set LD_LIBRARY_PATH accordingly (to cuda/lib64).

You could be having this problem if you installed the latest version of CUDA (9.0). If this is the case, you'll have the libcusolver.so.9.0 file or directory on your computer, but not 8.0, so python can't find it to import. Tensorflow doesn't yet support CUDA 9.0 (as of Oct 18th 2017).

To fix this, install CUDA 8.0, which can be found here. You can find all their legacy releases at the bottom of the main download page.
