title: Pytorch cuda version can not install
body: <p>In the beginning, I checked my cuda version using <code>nvcc --version</code> command and it shows version as <strong>10.2</strong>
  So i started to install pytorch with cuda based on instruction in <a href="https://pytorch.org/get-started/locally/" rel="nofollow noreferrer">pytorch</a> so I tried with bellow command in anaconda prompt with python 3.8.3 virtual environment</p>
  <p><code>conda install pytorch torchvision torchaudio cudatoolkit=10.2 -c pytorch</code></p>
  <p>in terminal it shows</p>
  <pre><code>    added / updated specs:
          - cudatoolkit=10.2
          - pytorch
          - torchaudio
          - torchvision
  
  The following NEW packages will be INSTALLED:
  
      cudatoolkit: 10.2.89-h74a9793_1
      pytorch:     1.7.0-py3.8_cpu_0  pytorch [cpuonly]
      torchaudio:  0.7.0-py38         pytorch
      torchvision: 0.8.1-py38_cpu     pytorch [cpuonly]
  </code></pre>
  <p>there are no any errors in installing process and then I try with below codes in notebook by activating this installed environment</p>
  <pre><code>import torch
  print(torch.__version__, torch.cuda.get_device_properties(0) if torch.cuda.is_available() else 'CPU')
  </code></pre>
  <p>output was <code>1.7.0 CPU</code></p>
  <p>so I run <code>conda list PyTorch</code> command in anaconda prompt</p>
  <p>it also shows below output</p>
  <pre><code># Name                    Version                   Build  Channel
  pytorch                   1.7.0               py3.8_cpu_0  [cpuonly]  pytorch
  </code></pre>
  <p>why it didn't install the GPU version and how can I fix this</p>
  <p>Thank you</p>
