Sorry, for the delay. The dimensions are BatchSize, Channels, Z, Y, X. The point is to create 16 channels, not to increase the batch size by 16x.

If my understanding is right, the concatenation in the InputTransition block should be applied along dim=1 instead of dim=0, because the second dimension is channel. i.e.

# split input in to 16 channels
x16 = torch.cat((x, x, x, x, x, x, x, x,
                 x, x, x, x, x, x, x, x), 0)

should be

# split input in to 16 channels
x16 = torch.cat((x, x, x, x, x, x, x, x,
                 x, x, x, x, x, x, x, x), 1)

In the meanwhile, the x's channel number is changed via conv1, so that it needs to save the original input(whose channel number is 1), namely

split input in to 16 channels

x16 = torch.cat((input_x, input_x, input_x, input_x, input_x, input_x, input_x, input_x,
input_x, input_x, input_x, input_x, input_x, input_x, input_x, input_x), 1)

Thx very much for the apply!
