title: pip ERROR: No matching distribution found for tensorflow==1.6.0
body: <p>I am trying to install tensorflow 1.6.0 to use a python project, I'm on ubuntu 20</p>
  <p>The problem is that I couldn't find the tensorflow 1.6.0 as its needed by the project and it doesnt work on tensorflow +2, this is the error I'm getting :</p>
  <pre><code>ERROR: Could not find a version that satisfies the requirement tensorflow==1.6.0 (from versions: 2.2.0rc1, 2.2.0rc2, 2.2.0rc3, 2.2.0rc4, 2.2.0, 2.3.0rc0, 2.3.0rc1, 2.3.0rc2, 2.3.0)
  ERROR: No matching distribution found for tensorflow==1.6.0
  </code></pre>
  <p>my pip version is 20.0.2 and i have a python 3.8.2 64bit, what is causing this problem? why pip cannot find tensorflow versions below 2?</p>
  <p>the only close solution i found was this :</p>
  <p><a href="https://stackoverflow.com/questions/42317075/tensorflow-r1-0-could-not-a-find-a-version-that-satisfies-the-requirement-tens">Tensorflow r1.0 : could not a find a version that satisfies the requirement tensorflow</a></p>
  <p>but the links in the tensorflow webpage for linux are all for tensorflow +2 and when i replace the version with 1.6.0 it doesnt work anymore :</p>
