question about model.py

[wooodswu]

Need your help! I have a question about this “losses_fn", except in the definition of “outputs_losses”, i cannot find this function. When I want to change the loss function, and using the following: /*code net = dde.maps.DeepONetCartesianProd( [101,30,30,101], [1,30,30,101], "relu", "Glorot normal") model2 =dde.Model(data, net) model2.compile("adam", lr=3e-4, loss=“mse", metrics=["l2 relative error"], ) */ dde.Model.compile(): loss, by my understanding, is just the “loss_fn”(here is just mse) in the “losses_fn", and I cannot find the “losses_fn” in the whole package. My question: could I change this losses_fn? is this the loss function I need to define? Or in the somewhere of the model, where can I change the loss?
