Where is the pruning process for the Tensorflow code?

[osseney]

This isn't really an issue per se, I just wasn't sure where to post my question.

I'm using this code to understand what happens when I add/remove convolution layers, change the filter sizes, etc. I'm looking for pruning methods used within the code so I can fiddle with them and I'm having difficulty finding them in the code.

Could someone point out to me which code module the pruning methods are present in? I'm a beginner with AI and I'm trying to learn. Thanks
