WebApr 13, 2024 · 剪枝不重要的通道有时可能会暂时降低性能,但这个效应可以通过接下来的修剪网络的微调来弥补. 剪枝后,由此得到的较窄的网络在模型大小、运行时内存和计算操作方面比初始的宽网络更加紧凑。. 上述过程可以重复几次,得到一个多通道网络瘦身方案,从而 ... WebSep 14, 2024 · The requires_grad is a parameter we pass into the function to tell PyTorch that this is something we want to keep track of later for something like backpropagation using gradient computation. In other words, it “tags” the object for PyTorch. Let’s make up some dummy operations to see how this tagging and gradient calculation works.
