#Visualizing feature maps of VGGFace2 model by Gradient visualization Backpropagation technique and GradCAM heatMap

1.Repackage the model structure of VGGFace2 model from layer by layer, to block by block;

2.Using Gradient visualization Backpropagation methods to print out the featurmap on each blocks;

3.Using GradCam technique to print out heatmap on each block.
