filter pruning or channel pruning?

[wzd-fanshan]

Hello!
I am a beginner, and I would like to ask you a question that puzzles me.
When I read the paper PRUNING FILTERS FOR EFFICIENT CONVNETS, I found that Pruning a filter results in removal of its corresponding feature map and related kernels in the next layer.
However, in the code I only found actions to remove filters at the i th layer and did not remove related Kernels in the next layer.
So is this code channel pruning or filter pruning?
