title: how to implement Grad-CAM on your own network?
body: <p>I want to implement Grad-CAM on my own network, should I save my model and load it, then treat my saved model like VGG-16, then do similar operations?</p>
  
  <p>I tried to search on the internet, and I found that all methods are based on famous models, not their owns.</p>
  
  <p>So I wonder, maybe I just need to treat my own model as VGG-16, then do similar things.</p>
