Trainer.fit() on a List or Dict of multiple models

[XezXey]

Is there a way to run trainer.fit() on multiple models?.
For example, I have dict of the models

GANs = {'generator' : gen(), 'discriminator' : dis()}

And in my LightningModule, I have set the
self.model = GANs

The problem is once I run the trainer.fit(self, self.data). Lightning won't find any parameters that require a gradient and the error is raised.
RuntimeError: DistributedDataParallel is not needed when a module doesn't have any parameter that requires a gradient.
