Hi, I have the same issue, Did you solve it?

[confymacs]

Hi, I changed the 'strict' parameter in the scheduler to 'False' (by default it should be True) and solved the problem. Here is how I modified the configure_optimizer function:

def configure_optimizers(self):
        opt = hydra.utils.instantiate(
            self.hparams.optim.optimizer, params=self.parameters(), _convert_="partial"
        )
        if not self.hparams.optim.use_lr_scheduler:
            return [opt]
        scheduler = hydra.utils.instantiate(
            self.hparams.optim.lr_scheduler, optimizer=opt
        )
       
        return {"optimizer": opt, 
                "lr_scheduler": {
                    "scheduler": scheduler,
                    "monitor": "val_loss",
                    "strict": False}}
