How to downgrade tensorflow, multiple versions possible? : <p>I have tensorflow 1.2.1 installed, and I need to downgrade it to version 1.1 to run a specific tutorial. What is the safe way to do it? I am using windows 10, python 3.5. Tensorflow was installed with pip3, but "pip3 show tensorflow" returns blank.</p>

<p>Is it possible to have multiple version of tensorflow on the same OS? </p>
