title: CUDA_HOME path for Tensorflow
body: <p>The <a href="https://www.tensorflow.org/install/install_linux" rel="noreferrer">Tensorflow linux installation instructions</a> say:</p>
  
  <blockquote>
    <p>Ensure that you create the CUDA_HOME environment variable as described
    in the NVIDIA documentation.</p>
  </blockquote>
  
  <p>I cannot find any mention of CUDA_HOME in the NVIDIA instructions for cuDNN v6 or in the <a href="http://docs.nvidia.com/cuda/cuda-installation-guide-linux/index.html#introduction" rel="noreferrer">NVIDIA CUDA Toolkit install instructions</a>. Does anyone know how this variable should be set on linux?</p>
