title: TensorFlow (GPU) libcudart.so.7.5 error -- cannot open shared object file
body: <p>Installing TensorFlow with GPU on Ubuntu 14.04. Fairly new to the Ubuntu/UNIX environment so lots of things I don't get. When searching this issue, I came across instances of being unable to import CUDA 7.0 when they have CUDA 7.5 installed (since TensorFlow doesn't support 7.5). I have CUDA 7.0 installed, but it seems to be looking for 7.5 - why is this? I have in my .bashrc file the following lines:</p>
  
  <pre><code>export LD_LIBRARY_PATH="$LD_LIBRARY_PATH:/usr/local/cuda-7.0/lib64"
  export CUDA_HOME=/usr/local/cuda-7.0
  </code></pre>
  
  <p>But I'm still seeing the issue below... Anyone have any advice?</p>
