ConcatOp error when changing layer_depth=3 to a larger value in circle demo. about unet

Yay! Thanks much; I was able to merge your new master into my branch, and this seems to have fixed the issue for me. : )

Hi @avose, thanks for reporting this.
Looks like, that the resolution that I used in the demo and layer_depth=4 is resulting in feature maps that can't be concatenated (35 vs 34 pixels).

I've run the demo using images of size 572x572 (as proposed in the original paper) and then the problem doesn't occur:

circles.load_data(100, nx=572, ny=572, r_max=20)

I will have to dig a bit deeper to figure out what is really causing this issue

@avose I wrote a fix and just merged it into master. Let me know if it works now
