title: Installing coremltools on Python 3.6 Anaconda environment
body: <p>I am trying to install <code>coremltools</code> following the instructions from <a href="https://anaconda.org/derickl/coremltools" rel="nofollow noreferrer">Converter tools for Core ML.</a>:</p>
  
  <pre><code>(coreml) imac:~ henrik$ conda install -c derickl coremltools
  Fetching package metadata .............
  Solving package specifications: .
  
  UnsatisfiableError: The following specifications were found to be in conflict:
    - coremltools -&gt; python &gt;=2.7,&lt;2.8.0a0
    - python 3.6*
  Use "conda info &lt;package&gt;" to see the dependencies for each package.
  
  (coreml) imac:~ henrik$ python -V
  Python 3.6.3 :: Anaconda, Inc.
  </code></pre>
  
  <p>As you can see, the environment is running Python 3.6.3, which should satisfy the 3.6* dependency. However, I keep getting the <code>UnsatisfiableError</code>.</p>
  
  <p>I tried install <code>numpy</code> and <code>protobuf</code> in the environment, as they are listed as dependencies at <a href="https://github.com/apple/coremltools" rel="nofollow noreferrer">Apple's GitHub page for coremltools</a>, but that did not change anything.</p>
