title: How to download tensorflow 1.14.0 on Pycharm?
body: <p>My assignment needs to use <code>tensorflow 1.14.0</code>, yet it reports:</p>
  <pre><code>ERROR: Could not find a version that satisfies the requirement tensorflow&lt;1.15.0,&gt;=1.14.0 (from -r requirements.txt (line 3)) (from
  versions: 2.2.0rc1, 2.2.0rc2, 2.2.0rc3, 2.2.0rc4, 2.2.0, 2.2.1,
  2.3.0rc0, 2.3.0rc1, 2.3.0rc2, 2.3.0, 2.3.1, 2.4.0rc0, 2.4.0rc1, 2.4.0rc2, 2.4.0rc3, 2.4.0rc4, 2.4.0)
  </code></pre>
  <p>It is the same result when I tried to use pip in the console. It seems that old version of <code>tensorflow</code> is not supported now, but my assignment requires that old version. Is there a way to download the older version? Or can the <code>tensorflow</code> 2 identify the code in <code>tensorflow 1.14.0</code>?</p>
