I ran into the same error. Please double-check input on which Conv2D operation takes place of all paths( e.g. First, Second), especially shortcut path. And keep “training” as a variable rather than True or False.
I completely checked my code. I’ve done exactly the same thing which was written in the instructions. But I’m unable to figure out how am I supposed to get wrong values while training.
Can you once share your work if possible. I would like to refer that.
