title: ImportError: Could not find 'cudart64_100.dll
body: <p>I'm trying to install <code>tensorflow-gpu==2.0.0-beta1</code> on my Windows 10 machine and got this error:</p>
  
  <blockquote>
    <p>ImportError: Could not find 'cudart64_100.dll'. TensorFlow requires
    that this DLL be installed in a directory that is named in your %PATH%
    environment variable. Download and install CUDA 10.0 from this URL:

  <p>I made all things from:</p>
  
  <ul>
  <li>official documentation: <a href="https://www.tensorflow.org/install/gpu" rel="noreferrer">https://www.tensorflow.org/install/gpu</a></li>
  <li>from here: <a href="https://medium.com/@teavanist/install-tensorflow-gpu-on-windows-10-5a23c46bdbc7" rel="noreferrer">https://medium.com/@teavanist/install-tensorflow-gpu-on-windows-10-5a23c46bdbc7</a></li>
  <li>Checked <code>PATH</code> variable: <code>C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v10.0\bin</code></li>
  <li>also have <code>CUDA_PATH</code> : <code>C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v10.0</code> in variables</li>
  <li>file <code>C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v10.0\bin\cudart64_100.dll</code> exists</li>
  <li>Did system restart</li>
  </ul>
  
  <p>But error still occurs</p>
  
  <p>How can I fix this?</p>
