Hello,
One thing I want to point out, if we use torchvision default models (such as vgg16)
there is a Relu inplace =True
so even if I am trying to access the convolution layer (by layer Num, such as layer17, layer 28,) before Relu,
this hook method seems to return results after its corresponding Relu (i.e., negative values becomes zero)
for example, layer17 will  actually return results of layer18 (layer17+ReLU)
