Hi, I want to know whether libtorch must faster than python?  For example, if i run VGG16, Resnet50 on the CPU, how much faster libtorch can be than python?
when i run this experiment, i got a result that their time is very closed!. But when i test addmm function, libtorch can be 3~5x faster than python. Is this normal? why a pretrained model’s performance is very different from function’s？
