💬 Describe the reimplementation questions

I use measure_latency.py to measure latency. I always get the error "AttributeError: 'Namespace' object has no attribute 'options'". So I chose to use benchmark.py in the analysis tool to measure the latency of the model. Then I found that there was no difference in latency between the 42ms pre-trained model and the 33ms pre-trained model. And when I set the pruning ratio to 0, there is no significant change in latency.

This issue has been resolved. I found that I did not apply the pruning ratio correctly. I am curious how you measure MACs, is it measured at runtime or statically?
