Using built-in loss functions (e.g., keras.losses.MeanSquaredError()) works fine. Could this be related to changes in graph execution or how custom loss functions are handled in Keras 3? Let me know if you need any more details to debug this. Thanks!

Hello, I am trying to create a custom loss function in Keras, where the target values for my network and the output of my network are of different shapes. Here is the custom loss function I have defined: def custom_loss(y_true, y_pred): ...

The loss function should return a float tensor. If a custom `Loss` instance is used and reduction is set to `None`, return value has shape `(batch_size, d0, .. dN-1)` i.e. per-sample or per-timestep loss values; otherwise, it is a scalar. If the model has multiple outputs, ...
As you can see, we are passing the names of thelossfunctions for each output layer as Python dictionary and referring to the output layers using their namesy1andy2as keys in the dictionary. Finally, we need to callmodel.fit()as well. Again, as our neural network has two output layers,...
