Issue with Saliency Maps Becoming Zeros After Certain Training Steps

[AndyLee-01]

I have successfully run your project and attempted to apply the imagePerturbationSaliency and imageSarfa methods provided by you to my own pre-trained DQN model. I've noticed that as the model's performance improves, the saliency maps become increasingly clear. However, there's a peculiar issue: after a certain number of training steps, the saliency maps turn completely to zeros. I'm curious if you are aware of the reason behind this and if there's a solution to this problem. Thanks a lot!

I haven't encountered this problem, maybe you can find out why by debugging with breakpoints and let me know!
