title: Tensorflow can't find "cudart64_90.dll" even though it is installed with Path variable set
body: <p>I installed CUDA 9.0 because without it, Tensorflow gives the error:</p>
  <blockquote>
  <p>ImportError: Could not find 'cudart64_90.dll'. TensorFlow requires that this DLL be installed in a directory that is named in your %PATH% environment variable.</p>
  </blockquote>
  <p>I have the path variable set to the bin directory of CUDA 9.0 installation, where the required DLL file is present. I tried setting it to its parent directory too. But it still gives me the same error.
