Hi @yodada, I used your optimized conv2d code for 3x3 kernel and further write a similar version for 1x1 kernels. I also modified the
aten/src/Aten/native/hammerblade/Convolution.cppto enable the selection of the kernel implementation.These optimizations work fine on conv layers of convnet. Can you help me review the code?
