title: How to pip install old version of library(tensorflow)?
body: <p>I'm trying to install tensorflow r0.11. I tried</p>
  
  <pre><code>pip install tensorflow==r0.11
  pip install tensorflow&lt;0.12
  </code></pre>
  
  <p>But I get this error</p>
  
  <pre><code>Could not find a version that satisfies the requirement tensorflow==0.11.0 (from versions: 0.12.0rc0, 0.12.0rc1, 0.12.0, 0.12.1)
  No matching distribution found for tensorflow==0.11.0
  </code></pre>
  
  <p>I assume pip is no longer support depricated versions, how can I get it?</p>
  
  <p>I also tried</p>
  
  <pre><code>pip install git+git://github.com/tensorflow/tensorflow@r0.11
