i use  torch.nn.DataParallel for 4 gpu
when featuremap size is [128, 106, 32, 32], kernel_size=3, group=2, padding=1 in_channels=106, out_channels= 106
check for stride=2 and 1
splited featuremap size on each gpu is
torch.Size([32, 106, 32, 32])
misaligned address error is printed
i don’t know why this happens
other size with group=2 works well
