    python - multioutput-multiclass classificationin custom

    Well if you are not using .fit and using your own training loop - callbacks are irrelevant, since you are now in control of the training. About the custom loss, I believe it is quite the same - you can return a dictionary from your call() method, and then in the training step use 3 different losses to compute gradients and apply them them yourselves. . This also allows you to use the loss
