title: Specific package version with conda-forge
body: <p>I am trying to install a specific <code>Keras</code> version from <code>Keras 1 API</code> using <code>conda-forge</code>, because </p>
  
  <blockquote>
    <p><strong><code>$ conda search keras</code></strong> </p>
  </blockquote>
  
  <p>returns only the following <code>Keras 2 API</code> options:</p>
  
  <pre><code>keras                        2.0.8            py35h86bcf3e_0  defaults
                               2.0.8            py27h242e9fd_0  defaults
                               2.0.8            py36h39110e4_0  defaults
  </code></pre>
  
  <blockquote>
    <p>whereas <strong><code>$ conda search keras --channel conda-forge</code></strong> </p>
  </blockquote>
  
  <p>return more options, apart from the usual channels, like so:</p>

  <p>so, is it possible to install a <code>1.x</code> version using <code>conda-forge</code>? I can't find any documentation.</p>
  
  <p>if so, what is the proper syntax for the installation?</p>
