Using Grad-CAM for SSD network

[Fpooyan]

Hi,
Thanks for publishing this great repo! I am debugging an SSD network used for a 3-class object detection task.
Can I use this repo for visualizing such a network as well? I would appreciate it if you could provide me the initial steps...

@Fpooyan 您好，对于目标检测每个网络都不一样，SSD网络生成CAM图与RetinaNet比较类似，请问您基于哪个工程做SSD网络的可视化？可以互相交流一下~

Thanks for your quick response! I do not speak Chinese, so I am using translate to get you.
I want to find a way to visualize the base layers of my SSD so that I can see what features it is concentrating on. As SSD networks work with prior boxes, I thought their Grad-CAM must be something different.

@Fpooyan 您好，prior boxes 就是anchors；ssd,retinanet和faster r-cnn都是anchor-based 的目标检测；SSD和retinanet都是one-stage网络，都有特征金字塔，所有个人认为它们的Grad-CAM是类似的。请问你想基于哪个工程来做？
