How to use Auto Model For SequenceClassification for Multi-Class Text Classification?
I am trying to use Hugginface’s AutoModelForSequence Classification API for multi-class classification but am confused about its configuration.My dataset is in one hot encoded and the problem type is multi-class (one label at a time)What I have tried:from transformers import AutoModelForSequenceClassification

model = AutoModelForSequenceClassification.from_pretrained("bert-base-uncased",
                                                           num_labels=6,
                                                           id2label=id2label,
                                                           label2id=label2id)



batch_size = 8
metric_name = "f1"



from transformers import TrainingArguments, Trainer

args = TrainingArguments(
    f"bert-finetuned-english",
    evaluation_strategy = "epoch",
    save_strategy = "epoch",
    learning_rate=2e-5,
    per_device_train_batch_size=batch_size,
    per_device_eval_batch_size=batch_size,
    num_train_epochs=10,
    weight_decay=0.01,
    load_best_model_at_end=True,
    metric_for_best_model=metric_name,
    #push_to_hub=True,
)


trainer = Trainer(
    model,
    args,
    train_dataset=encoded_dataset["train"],
    eval_dataset=encoded_dataset["test"],
    tokenizer=tokenizer,
    compute_metrics=compute_metrics
)is it correct?I am confused about the loss function, when I am printing one forward pass the loss is BinaryCrossEntropyWithLogitsSequenceClassifierOutput([('loss',
                           tensor(0.6986, grad_fn=<BinaryCrossEntropyWithLogitsBackward0>)),
                          ('logits',
                           tensor([[-0.5496,  0.0793, -0.5429, -0.1162, -0.0551]],
                                  grad_fn=<AddmmBackward0>))])which is used for multi-label or binary classification tasks. It should use nn.CrossEntropyLoss?How to properly use this API for multiclass and define the loss function?

Also looking for this, did you figure it out?
