concatenation in denseblock

[jyu-theartofml]

Hi,
Maybe I'm not reading your code right, but I don't see a concatenation step after each convolution layer in the denseblock() function. I thought this was needed as shown in the paper.

THanks,

Agree with @yinniyu , I didn't see any concatenation operation inside the DenseBlock, if no dense connection, the network almost has no difference with U-Net except has more layers.

I don't see the skip connection in the denseblock() too. I plot the model. It is only a deep unet
