title: I have a GPU and CUDA installed in Windows 10 but Pytorch's torch.cuda.is_available() returns false; how can I correct this?
body: <p>I have PyTorch installed on a Windows 10 machine with a Nvidia GTX 1050 GPU. I have installed the CUDA Toolkit and tested it using <a href="https://docs.nvidia.com/cuda/cuda-installation-guide-microsoft-windows/index.html" rel="noreferrer">Nvidia instructions</a> and that has gone smoothly, including execution of the suggested tests.</p>
  
  <p>However, <code>torch.cuda.is_available()</code> returns <code>False</code>. How can I fix this?</p>
