title: Conda install of pytorch fails
body: <p>I created an environment with conda and I want to install pytorch in it, but it doesn't work. After I get inside my environment with <code>source activate env_name</code> I tried this: <code>conda install pytorch torchvision -c pytorch</code> (I also tried it like this: <code>conda install -c pytorch pytorch torchvision</code>) but I am getting this error:</p>
  
  <pre><code>Using Anaconda Cloud api site https://api.anaconda.org

  Error: Could not find some dependencies for pytorch: mkl &gt;=2018, cudatoolkit &gt;=9.0,&lt;9.1, blas * mkl, cudatoolkit &gt;=10.0,&lt;10.1, cudatoolkit &gt;=9.2,&lt;9.3, blas * openblas, cudnn 7.0.*, cudatoolkit 9.*
  
  Did you mean one of these?
  
      pytorch, pytorch-gpu, pytorch-cpu
  
  Did you mean one of these?
  
      cudatoolkit
  
  You can search for this package on anaconda.org with
  
      anaconda search -t conda cudatoolkit 9.*
  
   (and similarly for the other packages)
