title: Unable to install xgboost on conda-forge
body: <p>I tried to install xgboost on my Anaconda package on Windows 10. I'm using python 3.7.
  I ran the following command;</p>
  
  <pre><code>conda install -c conda-forge xgboost
  </code></pre>
  
  <p>I failed to do so. The error is shown below;</p>

  <p>If I try <code>conda install -c anaconda py-xgboost</code>, xgboost can be installed but I prefer the xgboost package from conda-forge because it's more updated.</p>
