About the inference speed of using FullGrad for cam visualization

[kasteric]

I was using FullGrad for cam visualization and found that it was much slower compared with ScoreCAM or GradCAM, and when using FullGrad for visualizations, there were warnings like Warning: target_layers is ignored in FullGrad. All bias layers will be used instead. Was it normal that using FullGrad was slow because it considered all layers? Or did I wrongly use the FullGrad?

Yes exactly, it is slower because it considered all layers.
