[AttributeError] Multiple validation dataloaders

[tchaton]

🐛 Bug

Please reproduce using the BoringModel and post here

        for dl_idx, dl_metrics in enumerate(step_metrics):
            if len(dl_metrics) == 0:
                continue
            reduced_epoch_metrics = dl_metrics[0].__class__.reduce_on_epoch_end(dl_metrics)
            # make the keys 'k/dl'
            reduced_epoch_metrics = self.__rename_keys_by_dataloader_idx(reduced_epoch_metrics, dl_idx, num_loaders)
            # track the metrics
            logger_metrics = reduced_epoch_metrics.get_epoch_log_metrics()

with __rename_keys_by_dataloader_idx

AttributeError 'dict' object has no attribute 'get_epoch_log_metrics'
