Access and change models optimizer after setup

what is the canonical way to access/change the optimizer of a pl.LightningModule after model.setup('fit') was called?

E.g. if I follow (the last part where I explicitly plot the found lr and then change it) I don’t see a way how to change the optimizers lr.
If I call model.configure_optimizers() it’ll just return the optimizer and not set them.
Is there no official way to access and change them after construction?


Hello, my apology for the late reply. We are slowly converging to deprecate this forum in favor of the GH build-in version… Could we kindly ask you to recreate your question there - Lightning Discussions
