Hi All Im Trying To Save My Model Checkpoints During Runtime But Am Running Into A Confusing Snag. I'M Using The Huggingface Architecture For A Transformer. Using Their Training Module To Control Training. In The Training Args, I Have The


training function:

def training(checkpoint, image_processor):

    data_test_train, labels, label_to_id, id_to_label = pre_process()

    model = AutoModelForImageClassification.from_pretrained(
        checkpoint,
        num_labels=len(labels),
        id2label=id_to_label,
        label2id=label_to_id,
        ),
    )
    def metrics(eval_pred):
        metric_val = config.get("eval_metric")
        metric = evaluate.load(metric_val)
        predictions, labels = eval_pred
        predictions = np.argmax(predictions, axis=1)
        if metric_val == "accuracy":
            return metric.compute(predictions=predictions, references=labels)
        else:
            return metric.compute(
                predictions=predictions, references=labels, average="weighted"
            )

    data_collator = DefaultDataCollator()

    training_args = TrainingArguments(
        output_dir="somefolder",
        remove_unused_columns=False,
        eval_strategy="epoch",
        save_strategy="epoch",
        learning_rate=config.get("learning_rate"),
        per_device_train_batch_size=config.get("train_batch_size"),
        gradient_accumulation_steps=config.get("gradient_steps"),
        per_device_eval_batch_size=config.get("eval_batch_size"),
        num_train_epochs=config.get("epochs"),
        warmup_ratio=config.get("warmup_ratio"),
        logging_steps=config.get("logging_steps"),
        save_total_limit=config.get("save_total"),
        load_best_model_at_end=True,
        report_to="tensorboard",
        metric_for_best_model=config.get("eval_metric"),
        push_to_hub=False,
    )
    trainer = Trainer(
        model=model.to(device),
        args=training_args,
        data_collator=data_collator,
        train_dataset=data_test_train["train"],
        eval_dataset=data_test_train["test"],
        tokenizer=image_processor,
        compute_metrics=metrics,
    )
    print("training")
    trainer.train()
    print("save_model")
    trainer.save_model()
    best_model = trainer.state.best_model_checkpoint
    print(best_model)
    classifification_report(data_test_train["test"], model, best_model)
    return best_model
