Hi,Now I use U-Net model,It shows C++:9.05s,python:0.796s, But when I used the resnet model, C++ was faster. Why is this happening?

Hi @DarkWings,
I know you posted this a while ago.
How are you measuring the runtime in C++, what batch-size do you use and are you using CPU or GPU?
For me the runtime was similar so far on MXNET Intel MKL, CPU, batch-size 1.
