The question related to groupconv2d

[ShihuaiXu]

thanks for you great work, I have a question related to your implemention of groupconv2d in keras. I compre the pytorch's implemention and your implemention, the official pytorch implemention of groupconv2d only use one conv2d, because the .pth file only contain one conv2d with 1/2 input channel as the perameter, and your implemention use two conv2d, which makes me confused, wold mind explain it to me?
