WebJun 23, 2024 · 8. I have not seen any parameter for that. However, there is a workaround. Use following combinations. evaluation_strategy =‘steps’, eval_steps = 10, # Evaluation and Save happens every 10 steps save_total_limit = 5, # Only last 5 models are saved. Older ones are deleted. load_best_model_at_end=True, Webeval_dataset (Union [torch.utils.data.Dataset, Dict [str, torch.utils.data.Dataset ]), optional) — The dataset to use for evaluation. If it is a Dataset, columns not accepted by the model.forward () method are automatically removed. If it is a dictionary, it will evaluate on each dataset prepending the dictionary key to the metric name.
