CAM

https://github.com/jacobgil/pytorch-grad-cam

 

Chosing the Target Layer

You need to choose the target layer to compute CAM for. Some common choices are:

  • FasterRCNN: model.backbone
  • Resnet18 and 50: model.layer4[-1]
  • VGG and densenet161: model.features[-1]
  • mnasnet1_0: model.layers[-1]
  • ViT: model.blocks[-1].norm1
  • SwinT: model.layers[-1].blocks[-1].norm1

If you pass a list with several layers, the CAM will be averaged accross them. This can be useful if you're not sure what layer will perform best.

 

 

!git clone https://github.com/frgfm/torch-cam.git
!pip install -e torch-cam/.

 

pip install torchcam

 

os.chdir("/data/pincer/other/Train_Custom_Dataset-main/")
