Mmdetection: Tools like grad cam

[NicholasIrving]

Are there any tools similar to grad cam or something to visualize the heat map?

Currently not. Community contribution is welcome.

Ablation cam , presented at WACV 2020 and gradients don't needed

@NicholasIrving
Did anyone implemented grad-cam to mmdetection? It is really useful.I tried with faster-rcnn,but got no clue.Any help?

I write some codes to visualize the heatmap from backbone and fpn, it works well.

I refer to some codes online, this code is rough and not rigorous(neng yong jiu xing)

em..., it randomly chooes a channel to draw heatmap. It doesn't reweight channels. (yong de bu fang xing)
I don't know how to get gradient in inference_detector function. It is key to visualize the heat map or cam

老哥，你这个只是随机抽取一个通道的特征图打印出来， 并不是grad_cam, grad_cam 重要的不是backwards 吗
