ValueError: Dimensions must be equal

This is the error message I got.

ValueError: Dimensions must be equal but are 9 and 4 for ‘{{node mean_absolute_percentage_error/sub}} = Sub[T=DT_FLOAT](IteratorGetNext:1, sequential_5/dense_11/Sigmoid)’ with input shapes: [32,9,4,4], [32,4,9,4].

​

But my output and my y are the same shapes
