Unable to perform assignment because the indices on the left side are not compatible with the size of the right side.
The functionLayer you created will only work with inputs that have a batch size of 1 - it is reshaping the input to K x 7 x 1 x...

U-net looses connections, becomes linear rather than U-shaped (unetLayers)
This is not being caused by the training, or saving and loading: the network is likely correct at that point. The loss of conne...
