title: Not possible to install tensorflow 1.3.0
body: <p>I am trying to get the `Mask R CNN to work from this Github repo: <a href="https://github.com/matterport/Mask_RCNN" rel="nofollow noreferrer">Mask_RCNN</a> </p>
  
  <p>This requires <code>TensorFlow 1.3.0</code> but when I try to install this specific version it just installs <code>TensorFlow 2.0.0</code> anyway. I am using the following command:</p>
  
  <pre><code>pip install tensorflow&gt;=1.3.0
  </code></pre>
  
  <p>I am also using python 3.7.1</p>
