Bug description
Using the latest Lightning-AI v 2.1
I have added vanilla BatchSizeFinder as a callback to my lightningmodule. After it finishes finding the correct batchsize, it breaks while calling function batch_size_scaling. The error message is:
File ~/miniconda3/envs/dl/lib/python3.10/site-packages/lightning/pytorch/tuner/batch_size_scaling.py:155, in __scale_batch_restore_params(trainer, params)
153 stage = trainer.state.stage
154 assert stage is not None
--> 155 setattr(trainer, f"limit_{stage.dataloader_prefix}_batches", params["limit_eval_batches"])
157 loop.load_state_dict(deepcopy(params["loop_state_dict"]))
158 loop.restarting = False
On debugging the params variable only has the following keys:
dict_keys(['loggers', 'callbacks', 'max_steps', 'limit_train_batches', 'limit_val_batches', 'loop_state_dict'])
So indeed the limit_eval_batches key does not exist in my lightningmodule. Happy to provide more info if needed.
Thanks
