   @masahi Thanks for asking that. Since winograd may impact the numerical stability and model accuracy, so I don't think it can be chosen by library implictly. Besides, Winograd doesn't always outperform direct convolution in MKL-DNN. It depends on the implementation and kernel size/shape. To make this feature request more clear, could you also explain what does you model look like and what's you expectation from MKL-DNN Winograd?
