title: What is the difference between a .ckpt and a .pth file in Pytorch?
body: <p>I am following a code from GitHub that uses Pytorch.
  The model is saved using :</p>
  <pre class="lang-py prettyprint-override"><code>model.save(ARGS.working_dir + '/model_%d.ckpt' % (epoch+1)).  
  </code></pre>
  <p>What is the difference between using <code>.pth</code> and <code>.ckpt</code> in Pytorch?</p>
