title: What is the difference between tf-nightly-gpu and tensorflow-gpu
body: <p>I've been working for a while with <code>tensorflow</code> and now i'm doing the learning staff on the GPU using <code>tensorflow-gpu</code>, where it seems like I'm facing a release bug and someone said that using <code>tf-nightly-gpu-2.0-preview</code> will solve the issue.</p>
  
  <p>So, what is the difference between <code>tf-nightly-gpu</code> and <code>tensorflow-gpu</code>, is it a beta version of it or what?</p>
  
  <p>thanks in advance.</p>
