Nicolas Patry c0fe313b61 Warning about too long input for fast tokenizers too
If truncation is not set in tokenizers, but the tokenization is too long
for the model (`model_max_length`), we used to trigger a warning that

The input would probably fail (which it most likely will).

This PR re-enables the warning for fast tokenizers too and uses common
code for the trigger to make sure it's consistent across.

### Syncing forked master with upstream (HuggingFace) master
To avoid pinging the upstream repository which adds reference notes to each upstream PR and sends unnessary notifications to the developers involved in these PRs,
when syncing the master branch of a forked repository, please, follow these steps:
1. When possible, avoid syncing with the upstream using a branch and PR on the forked repository. Instead merge directly into the forked master.
2. If a PR is absolutely necessary, use the following steps after checking out your branch:
```
$ git checkout -b your-branch-for-syncing
$ git pull --squash --no-commit upstream master
$ git commit -m '<your message without GitHub references>'
$ git push --set-upstream origin your-branch-for-syncing
```

# Migrating from previous packages
## Migrating from transformers `v3.x` to `v4.x`
A couple of changes were introduced when the switch from version 3 to version 4 was done. Below is a summary of the
expected changes:
#### 1. AutoTokenizers and pipelines now use fast (rust) tokenizers by default.
The python and rust tokenizers have roughly the same API, but the rust tokenizers have a more complete feature set.
This introduces two breaking changes:
- The handling of overflowing tokens between the python and rust tokenizers is different.
- The rust tokenizers do not accept integers in the encoding methods.
##### How to obtain the same behavior as v3.x in v4.x
- The pipelines now contain additional features out of the box. See the [token-classification pipeline with the `grouped_entities` flag](https://huggingface.co/transformers/main_classes/pipelines.html?highlight=textclassification#tokenclassificationpipeline).
- The auto-tokenizers now return rust tokenizers. In order to obtain the python tokenizers instead, the user may use the `use_fast` flag by setting it to `False`:
In version `v3.x`:
```py
from transformers import AutoTokenizer
tokenizer = AutoTokenizer.from_pretrained("bert-base-cased")
```
to obtain the same in version `v4.x`:
```py
from transformers import AutoTokenizer
tokenizer = AutoTokenizer.from_pretrained("bert-base-cased", use_fast=False)
```
#### 2. SentencePiece is removed from the required dependencies
The requirement on the SentencePiece dependency has been lifted from the `setup.py`. This is done so that we may have a channel on anaconda cloud without relying on `conda-forge`. This means that the tokenizers that depend on the SentencePiece library will not be available with a standard `transformers` installation.
This includes the **slow** versions of:
- `XLNetTokenizer`
- `AlbertTokenizer`
- `CamembertTokenizer`
- `MBartTokenizer`
- `PegasusTokenizer`
- `T5Tokenizer`
- `ReformerTokenizer`
- `XLMRobertaTokenizer`
##### How to obtain the same behavior as v3.x in v4.x
In order to obtain the same behavior as version `v3.x`, you should install `sentencepiece` additionally:
In version `v3.x`:
```bash
pip install transformers
```
to obtain the same in version `v4.x`:
```bash
pip install transformers[sentencepiece]
```
or
```bash
pip install transformers sentencepiece
```
#### 3. The architecture of the repo has been updated so that each model resides in its folder
The past and foreseeable addition of new models means that the number of files in the directory `src/transformers` keeps growing and becomes harder to navigate and understand. We made the choice to put each model and the files accompanying it in their own sub-directories.
This is a breaking change as importing intermediary layers using a model's module directly needs to be done via a different path.
##### How to obtain the same behavior as v3.x in v4.x
In order to obtain the same behavior as version `v3.x`, you should update the path used to access the layers.
In version `v3.x`:
```bash
from transformers.modeling_bert import BertLayer
```
to obtain the same in version `v4.x`:
```bash
from transformers.models.bert.modeling_bert import BertLayer
```
#### 4. Switching the `return_dict` argument to `True` by default
The [`return_dict` argument](https://huggingface.co/transformers/main_classes/output.html) enables the return of dict-like python objects containing the model outputs, instead of the standard tuples. This object is self-documented as keys can be used to retrieve values, while also behaving as a tuple as users may retrieve objects by index or by slice.
This is a breaking change as the limitation of that tuple is that it cannot be unpacked: `value0, value1 = outputs` will not work.
##### How to obtain the same behavior as v3.x in v4.x
In order to obtain the same behavior as version `v3.x`, you should specify the `return_dict` argument to `False`, either in the model configuration or during the forward pass.
In version `v3.x`:
```bash
model = BertModel.from_pretrained("bert-base-cased")
outputs = model(**inputs)
```
to obtain the same in version `v4.x`:
```bash
model = BertModel.from_pretrained("bert-base-cased")
outputs = model(**inputs, return_dict=False)
```
or
```bash
model = BertModel.from_pretrained("bert-base-cased", return_dict=False)
outputs = model(**inputs)
```
#### 5. Removed some deprecated attributes
Attributes that were deprecated have been removed if they had been deprecated for at least a month. The full list of deprecated attributes can be found in [#8604](https://github.com/huggingface/transformers/pull/8604).
Here is a list of these attributes/methods/arguments and what their replacements should be:
In several models, the labels become consistent with the other models:
- `masked_lm_labels` becomes `labels` in `AlbertForMaskedLM` and `AlbertForPreTraining`.
- `masked_lm_labels` becomes `labels` in `BertForMaskedLM` and `BertForPreTraining`.
- `masked_lm_labels` becomes `labels` in `DistilBertForMaskedLM`.
- `masked_lm_labels` becomes `labels` in `ElectraForMaskedLM`.
- `masked_lm_labels` becomes `labels` in `LongformerForMaskedLM`.
- `masked_lm_labels` becomes `labels` in `MobileBertForMaskedLM`.
- `masked_lm_labels` becomes `labels` in `RobertaForMaskedLM`.
- `lm_labels` becomes `labels` in `BartForConditionalGeneration`.
- `lm_labels` becomes `labels` in `GPT2DoubleHeadsModel`.
- `lm_labels` becomes `labels` in `OpenAIGPTDoubleHeadsModel`.
- `lm_labels` becomes `labels` in `T5ForConditionalGeneration`.
In several models, the caching mechanism becomes consistent with the other models:
- `decoder_cached_states` becomes `past_key_values` in all BART-like, FSMT and T5 models.
- `decoder_past_key_values` becomes `past_key_values` in all BART-like, FSMT and T5 models.
- `past` becomes `past_key_values` in all CTRL models.
- `past` becomes `past_key_values` in all GPT-2 models.
Regarding the tokenizer classes:
- The tokenizer attribute `max_len` becomes `model_max_length`.
- The tokenizer attribute `return_lengths` becomes `return_length`.
- The tokenizer encoding argument `is_pretokenized` becomes `is_split_into_words`.
Regarding the `Trainer` class:
- The `Trainer` argument `tb_writer` is removed in favor of the callback `TensorBoardCallback(tb_writer=...)`.
- The `Trainer` argument `prediction_loss_only` is removed in favor of the class argument `args.prediction_loss_only`.
- The `Trainer` attribute `data_collator` should be a callable.
- The `Trainer` method `_log` is deprecated in favor of `log`.
- The `Trainer` method `_training_step` is deprecated in favor of `training_step`.
- The `Trainer` method `_prediction_loop` is deprecated in favor of `prediction_loop`.
- The `Trainer` method `is_local_master` is deprecated in favor of `is_local_process_zero`.
- The `Trainer` method `is_world_master` is deprecated in favor of `is_world_process_zero`.
Regarding the `TFTrainer` class:
- The `TFTrainer` argument `prediction_loss_only` is removed in favor of the class argument `args.prediction_loss_only`.
- The `Trainer` method `_log` is deprecated in favor of `log`.
- The `TFTrainer` method `_prediction_loop` is deprecated in favor of `prediction_loop`.
- The `TFTrainer` method `_setup_wandb` is deprecated in favor of `setup_wandb`.
- The `TFTrainer` method `_run_model` is deprecated in favor of `run_model`.
Regarding the `TrainerArgument` class:
- The `TrainerArgument` argument `evaluate_during_training` is deprecated in favor of `evaluation_strategy`.
Regarding the Transfo-XL model:
- The Transfo-XL configuration attribute `tie_weight` becomes `tie_words_embeddings`.
- The Transfo-XL modeling method `reset_length` becomes `reset_memory_length`.
Regarding pipelines:
- The `FillMaskPipeline` argument `topk` becomes `top_k`.

#### Fine-tuning BERT on SQuAD1.0 with relative position embeddings
The following examples show how to fine-tune BERT models with different relative position embeddings. The BERT model
`bert-base-uncased` was pre-trained with default absolute position embeddings. We provide the following pre-trained
models which were pre-trained on the same training data (BooksCorpus and English Wikipedia) as in the BERT model
training, but with different relative position embeddings.
* `zhiheng-huang/bert-base-uncased-embedding-relative-key`, trained from scratch with relative embedding proposed by
Shaw et al., [Self-Attention with Relative Position Representations](https://arxiv.org/abs/1803.02155)
* `zhiheng-huang/bert-base-uncased-embedding-relative-key-query`, trained from scratch with relative embedding method 4
in Huang et al. [Improve Transformer Models with Better Relative Position Embeddings](https://arxiv.org/abs/2009.13658)
* `zhiheng-huang/bert-large-uncased-whole-word-masking-embedding-relative-key-query`, fine-tuned from model
`bert-large-uncased-whole-word-masking` with 3 additional epochs with relative embedding method 4 in Huang et al.

```
Training with the above command leads to the following results. It boosts the BERT default from f1 score of 88.52 to 90.54.
```bash
'exact': 83.6802270577105, 'f1': 90.54772098174814
```
The change of `max_seq_length` from 512 to 384 in the above command leads to the f1 score of 90.34. Replacing the above
model `zhiheng-huang/bert-base-uncased-embedding-relative-key-query` with
`zhiheng-huang/bert-base-uncased-embedding-relative-key` leads to the f1 score of 89.51. The changing of 8 gpus to one
gpu training leads to the f1 score of 90.71.
##### Large models fine-tuning

For instance, if documents are serialized as tab-separated csv files with the columns "title" and "text", one can use `use_own_knowledge_dataset.py` as follows:
```bash
python examples/rag/use_own_knowledge_dataset.py \
--csv_path path/to/my_csv \
--output_dir path/to/my_knowledge_dataset \
```
The created outputs in `path/to/my_knowledge_dataset` can then be used to finetune RAG as follows:
```bash
python examples/rag/finetune_rag.py \
--data_dir $DATA_DIR \
--output_dir $OUTPUT_DIR \
--model_name_or_path $MODEL_NAME_OR_PATH \
--model_type rag_sequence \
--fp16 \
--gpus 8
--index_name custom
--passages_path path/to/data/my_knowledge_dataset
--index_path path/to/my_knowledge_dataset_hnsw_index.faiss
```

## Japanese ELECTRA-small
We provide a Japanese **ELECTRA-Small** model, as described in [ELECTRA: Pre-training Text Encoders as Discriminators Rather Than Generators](https://openreview.net/pdf?id=r1xMH1BtvB).
Our pretraining process employs subword units derived from the [Japanese Wikipedia](https://dumps.wikimedia.org/jawiki/latest), using the [Byte-Pair Encoding](https://www.aclweb.org/anthology/P16-1162.pdf) method and building on an initial tokenization with [mecab-ipadic-NEologd](https://github.com/neologd/mecab-ipadic-neologd). For optimal performance, please take care to set your MeCab dictionary appropriately.
## How to use the discriminator in `transformers`

### How to use
You can use this model directly with a pipeline for text generation. Since the generation relies on some randomness, we
set a seed for reproducibility:
```python
>>> from transformers import pipeline, set_seed
>>> generator = pipeline('text-generation', model='e-tony/gpt2-rnm')
>>> set_seed(42)
>>> generator("Rick: I turned myself into a pickle, Morty!\nMorty: ", max_length=50, num_return_sequences=5)
[{'generated_text': "Rick: I turned myself into a pickle, Morty!\nMorty: I didn't want to have children. It was my fate! I'll pay my mom and dad.\nSnuffles: Well, at least we"},
{'generated_text': "Rick: I turned myself into a pickle, Morty!\nMorty: you know what happened?\n(Steven begins dragging people down the toilet with his hand. As Steven falls) The whole thing starts.\nA man approaches Steven"},
{'generated_text': "Rick: I turned myself into a pickle, Morty!\nMorty: Oh wait! And do you remember what I did to you?\nJerry: Uh, it didn't hurt. It should have hurt a lot since I"},

# RiskData Brazilian Portuguese NER
## Model description
This is a finetunned version from [Neuralmind BERTimbau] (https://github.com/neuralmind-ai/portuguese-bert/blob/master/README.md) for Portuguese language.
For more details, please see, (https://github.com/SecexSaudeTCU/noticias_ner).
## Intended uses & limitations
#### How to use
#### Limitations and bias
- The finetunned model was trained on a corpus with around 180 news articles crawled from Google News. The original project's purpose was to recognize named entities in news
related to fraud and corruption, classifying these entities in four classes: PERSON, ORGANIZATION, PUBLIC INSITUITION and LOCAL (PESSOA, ORGANIZAÇÃO, INSTITUIÇÃO PÚBLICA and LOCAL).
## Training data
The training data can be found at (https://github.com/SecexSaudeTCU/noticias_ner/blob/master/dados/labeled_4_labels.jsonl).
## Training procedure
## Eval results
accuracy: 0.98,
precision: 0.86
recall: 0.91
f1: 0.88
The score was calculated using this code:
```python
def align_predictions(predictions: np.ndarray, label_ids: np.ndarray) -> Tuple[List[int], List[int]]:
preds = np.argmax(predictions, axis=2)
batch_size, seq_len = preds.shape
out_label_list = [[] for _ in range(batch_size)]
preds_list = [[] for _ in range(batch_size)]
for i in range(batch_size):
for j in range(seq_len):
if label_ids[i, j] != nn.CrossEntropyLoss().ignore_index:
out_label_list[i].append(id2tag[label_ids[i][j]])
preds_list[i].append(id2tag[preds[i][j]])
return preds_list, out_label_list
def compute_metrics(p: EvalPrediction) -> Dict:
preds_list, out_label_list = align_predictions(p.predictions, p.label_ids)
return {
"accuracy_score": accuracy_score(out_label_list, preds_list),
"precision": precision_score(out_label_list, preds_list),
"recall": recall_score(out_label_list, preds_list),
"f1": f1_score(out_label_list, preds_list),
