Some weights of the model checkpoint at bert-base-cased were not used when initializing BertForSequenceClassification: ['cls.seq_relationship.bias', 'cls.predictions.bias', 'cls.predictions.transform.LayerNorm.weight', 'cls.predictions.decoder.weight', 'cls.predictions.transform.LayerNorm.bias', 'cls.seq_relationship.weight', 'cls.predictions.transform.dense.weight', 'cls.predictions.transform.dense.bias']
- This IS expected if you are initializing BertForSequenceClassification from the checkpoint of a model trained on another task or with another architecture (e.g. initializing a BertForSequenceClassification model from a BertForPreTraining model).
- This IS NOT expected if you are initializing BertForSequenceClassification from the checkpoint of a model that you expect to be exactly identical (initializing a BertForSequenceClassification model from a BertForSequenceClassification model).
Some weights of BertForSequenceClassification were not initialized from the model checkpoint at bert-base-cased and are newly initialized: ['classifier.weight', 'classifier.bias']
You should probably TRAIN this model on a down-stream task to be able to use it for predictions and inference.

trainer = Trainer(
    model,
    training_args,
    train_dataset=tokenized_datasets["train"],
    eval_dataset=tokenized_datasets["validation"],
    data_collator=data_collator,
    tokenizer=tokenizer,
    compute_metrics=compute_metrics,
)

trainer.train()

TrainOutput(global_step=690, training_loss=0.39697496718254643, metrics={'train_runtime': 74.2937, 'train_samples_per_second': 148.115, 'train_steps_per_second': 9.287, 'total_flos': 563360051116800.0, 'train_loss': 0.39697496718254643, 'epoch': 3.0})

Push to hub from the Trainer directly

You will need an authentication token with your Hugging Face credentials to use the push_to_hub method. Execute huggingface-cli login in your terminal or by uncommenting the following cell:

# !huggingface-cli login

The Trainer has a new method to directly upload the model, tokenizer and model configuration in a repo on the Hub. It will even auto-generate a model card draft using the hyperparameters and evaluation results!

trainer.push_to_hub(repo_name="finetuned-bert")
# trainer.push_to_hub(repo_name="finetuned-bert", organization="huggingface")

'https://huggingface.co/sgugger/finetuned-bert/commit/12c9aaaadf60e2c48e9419524f3170f445a120d6'

If you are using your own training loop, you can push the model and tokenizer separately (and you will have to write the model card yourself):

# model.push_to_hub("finetuned-bert")
# tokenizer.push_to_hub("finetuned-bert")

You can load your model from anywhere using from_pretrained!

from transformers import AutoModelForSequenceClassification

model_name = "sgugger/finetuned-bert"
model = AutoModelForSequenceClassification.from_pretrained(model_name)

You can use your model in a pipeline!

classifier = pipeline("text-classification", model=model_name)

[{'label': 'LABEL_0', 'score': 0.7789641618728638}]

Updating a problematic file is super easy!

model.config.label2id = {"not equivalent": 0, "equivalent": 1}

model.config.id2label = {0: "not equivalent", 1: "equivalent"}

model.config.push_to_hub("finetuned-bert")

classifier = pipeline("text-classification", model=model_name)

classifier("My name is Sylvain. [SEP] My name is Lysandre")
