`FacebookAI/xlm-mlm-ende-1024` (マスク化された蚀語モデリング、英語-ドむツ語) - `FacebookAI/xlm-mlm-enfr-1024` (マスク化された蚀語モデリング、英語-フランス語) - `FacebookAI/xlm-mlm-enro-1024` (マスク化された蚀語モデリング、英語-ルヌマニア語) - `FacebookAI/xlm-mlm-xnli15-1024` (マスク化された蚀語モデリング、XNLI 蚀語) - `FacebookAI/xlm-mlm-tlm-xnli15-1024` (マスク化された蚀語モデリング + 翻蚳 + XNLI 蚀語) - `FacebookAI/xlm-clm-enfr-1024` (因果蚀語モデリング、英語-フランス語) - `FacebookAI/xlm-clm-ende-1024` (因果蚀語モデリング、英語-ドむツ語) 蚀語の埋め蟌みは、モデルに枡される `input_ids` ず同じ圢状のテン゜ルずしお衚されたす。 これらのテン゜ルの倀は、䜿甚される蚀語に䟝存し、トヌクナむザヌの `lang2id` および `id2lang` 属性によっお識別されたす。 この䟋では、`FacebookAI/xlm-clm-enfr-1024` チェックポむントをロヌドしたす (因果蚀語モデリング、英語-フランス語)。 ```py >>> import torch >>> from transformers import XLMTokenizer, XLMWithLMHeadModel >>> tokenizer = XLMTokenizer.from_pretrained("FacebookAI/xlm-clm-enfr-1024") >>> model = XLMWithLMHeadModel.from_pretrained("FacebookAI/xlm-clm-enfr-1024") ``` トヌクナむザヌの `lang2id` 属性は、このモデルの蚀語ずその ID を衚瀺したす。 ```py >>> print(tokenizer.lang2id) {'en': 0, 'fr': 1} ``` 次に、入力䟋を䜜成したす。 ```py >>> input_ids = torch.tensor([tokenizer.encode("Wikipedia was used to")]) # batch size of 1 ``` 蚀語 ID を `en` に蚭定し、それを䜿甚しお蚀語の埋め蟌みを定矩したす。 蚀語の埋め蟌みは、英語の蚀語 ID であるため、`0` で埋められたテン゜ルです。 このテン゜ルは `input_ids` ず同じサむズにする必芁がありたす。 ```py >>> language_id = tokenizer.lang2id["en"] # 0 >>> langs = torch.tensor([language_id] * input_ids.shape[1]) # torch.tensor([0, 0, 0, ..., 0]) >>> # We reshape it to be of size (batch_size, sequence_length) >>> langs = langs.view(1, -1) # is now of shape [1, sequence_length] (we have a batch size of 1) ``` これで、`input_ids` ず蚀語の埋め蟌みをモデルに枡すこずができたす。 ```py >>> outputs = model(input_ids, langs=langs) ``` [run_generation.py](https://github.com/huggingface/transformers/tree/main/examples/pytorch/text-generation/run_generation.py) スクリプトは、`xlm-clm` チェックポむントを䜿甚しお、蚀語が埋め蟌たれたテキストを生成できたす。 ### 蚀語の埋め蟌みがないXLM 次の XLM モデルは、掚論䞭に蚀語の埋め蟌みを必芁ずしたせん。 -

[example["video"].permute(1, 0, 2, 3) for example in examples] ... ) ... labels = torch.tensor([example["label"] for example in examples]) ... return {"pixel_values": pixel_values, "labels": labels} ``` 次に、これらすべおをデヌタセットずずもに`Trainer`に枡すだけです。 ```py >>> trainer = Trainer( ... model, ... args, ... train_dataset=train_dataset, ... eval_dataset=val_dataset, ... tokenizer=image_processor, ... compute_metrics=compute_metrics, ... data_collator=collate_fn, ... ) ``` すでにデヌタを前凊理しおいるのに、なぜトヌクナむザヌずしお`image_processor`を枡したのか䞍思議に思うかもしれたせん。これは、むメヌゞ プロセッサ構成ファむル (JSON ずしお保存) もハブ䞊のリポゞトリにアップロヌドされるようにするためだけです。 次に、`train` メ゜ッドを呌び出しおモデルを埮調敎したす。 ```py >>> train_results = trainer.train() ``` トレヌニングが完了したら、 [`~transformers.Trainer.push_to_hub`] メ゜ッドを䜿甚しおモデルをハブに共有し、誰もがモデルを䜿甚できるようにしたす。 ```py >>> trainer.push_to_hub() ``` ## Inference モデルを埮調敎したので、それを掚論に䜿甚できるようになりたした。 掚論のためにビデオをロヌドしたす。 ```py >>> sample_test_video = next(iter(test_dataset)) ``` <div class="flex justify-center"> <img src="https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/transformers/tasks/sample_gif_two.gif" alt="Teams playing basketball"/> </div> 掚論甚に埮調敎されたモデルを詊す最も簡単な方法は、それを [`pipeline`](https://huggingface.co/docs/transformers/main/en/main_classes/pipelines#transformers.VideoClassificationPipeline). で䜿甚するこずです。モデルを䜿甚しおビデオ分類甚の` pipeline`をむンスタンス化し、それにビデオを枡したす。 ```py >>> from transformers import pipeline >>> video_cls = pipeline(model="my_awesome_video_cls_model") >>> video_cls("https://huggingface.co/datasets/sayakpaul/ucf101-subset/resolve/main/v_BasketballDunk_g14_c06.avi") [{'score': 0.9272987842559814, 'label': 'BasketballDunk'}, {'score': 0.017777055501937866, 'label': 'BabyCrawling'}, {'score': 0.01663011871278286, 'label': 'BalanceBeam'}, {'score': 0.009560945443809032, 'label': 'BandMarching'}, {'score': 0.0068979403004050255, 'label': 'BaseballPitch'}] ``` 必芁に応じお、`pipeline`の結果を手動で耇補するこずもできたす。 ```py >>> def run_inference(model, video): ... # (num_frames, num_channels, height, width) ... perumuted_sample_test_video = video.permute(1, 0, 2, 3) ... inputs = { ... "pixel_values": perumuted_sample_test_video.unsqueeze(0), ... "labels": torch.tensor( ...

## Token classification Based on the scripts [`run_ner.py`](https://github.com/huggingface/transformers/blob/main/examples/legacy/token-classification/run_ner.py). The following examples are covered in this section: * NER on the GermEval 2014 (German NER) dataset * Emerging and Rare Entities task: WNUT’17 (English NER) dataset Details and results for the fine-tuning provided by @stefan-it. ### GermEval 2014 (German NER) dataset #### Data (Download and pre-processing steps) Data can be obtained from the [GermEval 2014](https://sites.google.com/site/germeval2014ner/data) shared task page. Here are the commands for downloading and pre-processing train, dev and test datasets. The original data format has four (tab-separated) columns, in a pre-processing step only the two relevant columns (token and outer span NER annotation) are extracted: ```bash curl -L 'https://drive.google.com/uc?export=download&id=1Jjhbal535VVz2ap4v4r_rN1UEHTdLK5P' \ | grep -v "^#" | cut -f 2,3 | tr '\t' ' ' > train.txt.tmp curl -L 'https://drive.google.com/uc?export=download&id=1ZfRcQThdtAR5PPRjIDtrVP7BtXSCUBbm' \ | grep -v "^#" | cut -f 2,3 | tr '\t' ' ' > dev.txt.tmp curl -L 'https://drive.google.com/uc?export=download&id=1u9mb7kNJHWQCWyweMDRMuTFoOHOfeBTH' \ | grep -v "^#" | cut -f 2,3 | tr '\t' ' ' > test.txt.tmp ``` The GermEval 2014 dataset contains some strange "control character" tokens like `'\x96', '\u200e', '\x95', '\xad' or '\x80'`. One problem with these tokens is, that `BertTokenizer` returns an empty token for them, resulting in misaligned `InputExample`s. The `preprocess.py` script located in the `scripts` folder a) filters these tokens and b) splits longer sentences into smaller ones (once the max. subtoken length is reached). Let's define some variables that we need for further pre-processing steps and training the model: ```bash export MAX_LENGTH=128 export BERT_MODEL=google-bert/bert-base-multilingual-cased ``` Run the pre-processing script on training, dev and test datasets: ```bash python3 scripts/preprocess.py train.txt.tmp $BERT_MODEL $MAX_LENGTH > train.txt python3 scripts/preprocess.py dev.txt.tmp $BERT_MODEL $MAX_LENGTH > dev.txt python3 scripts/preprocess.py test.txt.tmp $BERT_MODEL $MAX_LENGTH > test.txt ``` The GermEval 2014 dataset has much more labels than CoNLL-2002/2003 datasets, so an own set of labels must be used: ```bash cat train.txt dev.txt test.txt | cut -d " " -f 2 | grep -v "^$"| sort | uniq > labels.txt ``` #### Prepare the run Additional environment variables must be set: ```bash export OUTPUT_DIR=germeval-model export BATCH_SIZE=32 export NUM_EPOCHS=3 export SAVE_STEPS=750 export SEED=1 ``` #### Run the Pytorch version To start training, just run: ```bash python3 run_ner.py --data_dir ./ \ --labels ./labels.txt \ --model_name_or_path $BERT_MODEL \ --output_dir $OUTPUT_DIR \ --max_seq_length $MAX_LENGTH \ --num_train_epochs $NUM_EPOCHS \ --per_device_train_batch_size $BATCH_SIZE \ --save_steps $SAVE_STEPS \ --seed $SEED \ --do_train \ --do_eval \ --do_predict ``` If your GPU supports half-precision training, just add the `--fp16` flag. After training, the model will be both evaluated on development and test datasets. #### JSON-based configuration file Instead of passing all parameters via commandline arguments, the `run_ner.py` script also supports reading parameters from a json-based configuration file: ```json { "data_dir": ".", "labels": "./labels.txt", "model_name_or_path": "google-bert/bert-base-multilingual-cased", "output_dir": "germeval-model", "max_seq_length": 128, "num_train_epochs": 3, "per_device_train_batch_size": 32, "save_steps": 750, "seed": 1, "do_train": true, "do_eval": true, "do_predict": true } ``` It must be saved with a `.json` extension and can be used by running `python3 run_ner.py config.json`. #### Evaluation Evaluation on development dataset outputs the following for our example: ```bash 10/04/2019 00:42:06 - INFO - __main__ - ***** Eval results ***** 10/04/2019 00:42:06 - INFO - __main__ - f1 = 0.8623348017621146 10/04/2019 00:42:06 - INFO - __main__ - loss = 0.07183869666975543 10/04/2019 00:42:06 - INFO - __main__ - precision = 0.8467916366258111 10/04/2019 00:42:06 - INFO - __main__ - recall = 0.8784592370979806 ``` On the test dataset the following results could be achieved: ```bash 10/04/2019 00:42:42 - INFO - __main__ - ***** Eval results ***** 10/04/2019 00:42:42 - INFO - __main__ - f1 = 0.8614389652384803 10/04/2019 00:42:42 - INFO - __main__ - loss = 0.07064602487454782 10/04/2019 00:42:42 - INFO - __main__ - precision = 0.8604651162790697 10/04/2019 00:42:42 - INFO - __main__ - recall = 0.8624150210424085 ``` #### Run the Tensorflow 2 version To start training, just run: ```bash python3 run_tf_ner.py --data_dir ./ \ --labels ./labels.txt \ --model_name_or_path $BERT_MODEL \ --output_dir $OUTPUT_DIR \ --max_seq_length $MAX_LENGTH \ --num_train_epochs $NUM_EPOCHS \ --per_device_train_batch_size $BATCH_SIZE \ --save_steps $SAVE_STEPS \ --seed $SEED \ --do_train \ --do_eval \ --do_predict ``` Such as the Pytorch version, if your GPU supports half-precision training, just add the `--fp16` flag. After training, the model will be both evaluated on development and test datasets. #### Evaluation Evaluation on development dataset outputs the following for our example: ```bash precision recall f1-score support LOCderiv 0.7619 0.6154 0.6809 52 PERpart 0.8724 0.8997 0.8858 4057 OTHpart 0.9360 0.9466 0.9413 711 ORGpart 0.7015 0.6989 0.7002 269 LOCpart 0.7668 0.8488 0.8057 496 LOC 0.8745 0.9191 0.8963 235 ORGderiv 0.7723 0.8571 0.8125 91 OTHderiv 0.4800 0.6667 0.5581 18 OTH 0.5789 0.6875 0.6286 16 PERderiv 0.5385 0.3889 0.4516 18 PER 0.5000 0.5000 0.5000 2 ORG 0.0000 0.0000 0.0000 3 micro avg 0.8574 0.8862 0.8715 5968 macro avg 0.8575 0.8862 0.8713 5968 ``` On the test dataset the following results could be achieved: ```bash precision recall f1-score support PERpart 0.8847 0.8944 0.8896 9397 OTHpart 0.9376 0.9353 0.9365 1639 ORGpart 0.7307 0.7044 0.7173 697 LOC 0.9133 0.9394 0.9262 561 LOCpart 0.8058 0.8157 0.8107 1150 ORG 0.0000 0.0000 0.0000 8 OTHderiv 0.5882 0.4762 0.5263 42 PERderiv 0.6571 0.5227 0.5823 44 OTH 0.4906 0.6667 0.5652 39 ORGderiv 0.7016 0.7791 0.7383 172 LOCderiv 0.8256 0.6514 0.7282 109 PER 0.0000 0.0000 0.0000 11 micro avg 0.8722 0.8774 0.8748 13869 macro avg 0.8712 0.8774 0.8740 13869 ``` ### Emerging and Rare Entities task: WNUT’17 (English NER) dataset Description of the WNUT’17 task from the [shared task website](http://noisy-text.github.io/2017/index.html): > The WNUT’17 shared task focuses on identifying unusual, previously-unseen entities in the context of emerging discussions. > Named entities form the basis of many modern approaches to other tasks (like event clustering and summarization), but recall on > them is a real problem in noisy text - even among annotators. This drop tends to be due to novel entities and surface forms. Six labels are available in the dataset. An overview can be found on this [page](http://noisy-text.github.io/2017/files/). #### Data (Download and pre-processing steps) The dataset can be downloaded from the [official GitHub](https://github.com/leondz/emerging_entities_17) repository. The following commands show how to prepare the dataset for fine-tuning: ```bash mkdir -p data_wnut_17 curl -L 'https://github.com/leondz/emerging_entities_17/raw/master/wnut17train.conll' | tr '\t' ' ' > data_wnut_17/train.txt.tmp curl -L 'https://github.com/leondz/emerging_entities_17/raw/master/emerging.dev.conll' | tr '\t' ' ' > data_wnut_17/dev.txt.tmp curl -L 'https://raw.githubusercontent.com/leondz/emerging_entities_17/master/emerging.test.annotated' | tr '\t' ' ' > data_wnut_17/test.txt.tmp ``` Let's define some variables that we need for further pre-processing steps: ```bash export MAX_LENGTH=128 export BERT_MODEL=google-bert/bert-large-cased ``` Here we use the English BERT large model for fine-tuning. The `preprocess.py` scripts splits longer sentences into smaller ones (once the max. subtoken length is reached): ```bash python3 scripts/preprocess.py data_wnut_17/train.txt.tmp $BERT_MODEL $MAX_LENGTH > data_wnut_17/train.txt python3 scripts/preprocess.py data_wnut_17/dev.txt.tmp $BERT_MODEL $MAX_LENGTH > data_wnut_17/dev.txt python3 scripts/preprocess.py data_wnut_17/test.txt.tmp $BERT_MODEL $MAX_LENGTH > data_wnut_17/test.txt ``` In the last pre-processing step, the `labels.txt` file needs to be generated. This file contains all available labels: ```bash cat data_wnut_17/train.txt data_wnut_17/dev.txt data_wnut_17/test.txt | cut -d " " -f 2 | grep -v "^$"| sort | uniq > data_wnut_17/labels.txt ``` #### Run the Pytorch version Fine-tuning with the PyTorch version can be started using the `run_ner.py` script. In this example we use a JSON-based configuration file. This configuration file looks like: ```json { "data_dir": "./data_wnut_17", "labels": "./data_wnut_17/labels.txt", "model_name_or_path": "google-bert/bert-large-cased", "output_dir": "wnut-17-model-1", "max_seq_length": 128, "num_train_epochs": 3, "per_device_train_batch_size": 32, "save_steps": 425, "seed": 1, "do_train": true, "do_eval": true, "do_predict": true, "fp16": false } ``` If your GPU supports half-precision training, please set `fp16` to `true`. Save this JSON-based configuration under `wnut_17.json`. The fine-tuning can be started with `python3 run_ner_old.py wnut_17.json`. #### Evaluation Evaluation on development dataset outputs the following: ```bash 05/29/2020 23:33:44 - INFO - __main__ - ***** Eval results ***** 05/29/2020 23:33:44 - INFO - __main__ - eval_loss = 0.26505235286212275 05/29/2020 23:33:44 - INFO - __main__ - eval_precision = 0.7008264462809918 05/29/2020 23:33:44 - INFO - __main__ - eval_recall = 0.507177033492823 05/29/2020 23:33:44 - INFO - __main__ - eval_f1 = 0.5884802220680084 05/29/2020 23:33:44 - INFO - __main__ - epoch = 3.0 ``` On the test dataset the following results could be achieved: ```bash 05/29/2020 23:33:44 - INFO - transformers.trainer - ***** Running Prediction ***** 05/29/2020 23:34:02 - INFO - __main__ - eval_loss = 0.30948806500973547 05/29/2020 23:34:02 - INFO - __main__ - eval_precision = 0.5840108401084011 05/29/2020 23:34:02 - INFO - __main__ - eval_recall = 0.3994439295644115 05/29/2020 23:34:02 - INFO - __main__ - eval_f1 = 0.47440836543753434 ``` WNUT’17 is a very difficult task. Current state-of-the-art results on this dataset can be found [here](https://nlpprogress.com/english/named_entity_recognition.html).

# Token classification ## PyTorch version, no Trainer Fine-tuning (m)LUKE for token classification task such as Named Entity Recognition (NER), Parts-of-speech tagging (POS) or phrase extraction (CHUNKS). You can easily customize it to your needs if you need extra processing on your datasets. It will either run on a datasets hosted on our [hub](https://huggingface.co/datasets) or with your own text files for training and validation, you might just need to add some tweaks in the data preprocessing. The script can be run in a distributed setup, on TPU and supports mixed precision by the mean of the [🀗 `Accelerate`](https://github.com/huggingface/accelerate) library. You can use the script normally after installing it: ```bash pip install git+https://github.com/huggingface/accelerate ``` then to train English LUKE on CoNLL2003: ```bash export TASK_NAME=ner python run_luke_ner_no_trainer.py \ --model_name_or_path studio-ousia/luke-base \ --dataset_name conll2003 \ --task_name $TASK_NAME \ --max_length 128 \ --per_device_train_batch_size 32 \ --learning_rate 2e-5 \ --num_train_epochs 3 \ --output_dir /tmp/$TASK_NAME/ ``` You can then use your usual launchers to run in it in a distributed environment, but the easiest way is to run ```bash accelerate config ``` and reply to the questions asked. Then ```bash accelerate test ``` that will check everything is ready for training. Finally, you can launch training with ```bash export TASK_NAME=ner accelerate launch run_ner_no_trainer.py \ --model_name_or_path studio-ousia/luke-base \ --dataset_name conll2003 \ --task_name $TASK_NAME \ --max_length 128 \ --per_device_train_batch_size 32 \ --learning_rate 2e-5 \ --num_train_epochs 3 \ --output_dir /tmp/$TASK_NAME/ ``` This command is the same and will work for: - a CPU-only setup - a setup with one GPU - a distributed training with several GPUs (single or multi node) - a training on TPUs Note that this library is in alpha release so your feedback is more than welcome if you encounter any problem using it.

All examples in this folder are **TensorFlow** examples and are written using native Keras. If you've previously only used 🀗 Transformers via `TFTrainer`, we highly recommend taking a look at the new style - we think it's a big improvement! In addition, all scripts here now support the [🀗 Datasets](https://github.com/huggingface/datasets) library - you can grab entire datasets just by changing one command-line argument! ## A note on code folding Most of these examples have been formatted with #region blocks. In IDEs such as PyCharm and VSCode, these blocks mark named regions of code that can be folded for easier viewing. If you find any of these scripts overwhelming or difficult to follow, we highly recommend beginning with all regions folded and then examining regions one at a time! ## The Big Table of Tasks Here is the list of all our examples: | Task | Example datasets | |---|---| | [**`language-modeling`**](https://github.com/huggingface/transformers/tree/main/examples/tensorflow/language-modeling) | WikiText-2 | [**`multiple-choice`**](https://github.com/huggingface/transformers/tree/main/examples/tensorflow/multiple-choice) | SWAG | [**`question-answering`**](https://github.com/huggingface/transformers/tree/main/examples/tensorflow/question-answering) | SQuAD | [**`summarization`**](https://github.com/huggingface/transformers/tree/main/examples/tensorflow/summarization) | XSum | [**`text-classification`**](https://github.com/huggingface/transformers/tree/main/examples/tensorflow/text-classification) | GLUE | [**`token-classification`**](https://github.com/huggingface/transformers/tree/main/examples/tensorflow/token-classification) | CoNLL NER | [**`translation`**](https://github.com/huggingface/transformers/tree/main/examples/tensorflow/translation) | WMT ## Coming soon - **Colab notebooks** to easily run through these scripts!

For straightforward use-cases you may be able to use these scripts without modification, although we have also included comments in the code to indicate areas that you may need to adapt to your own projects. ## run_text_classification.py This script handles perhaps the single most common use-case for this entire library: Training an NLP classifier on your own training data. This can be whatever you want - you could classify text as abusive/hateful or allowable, or forum posts as spam or not-spam, or classify the genre of a headline as politics, sports or any number of other categories. Any task that involves classifying natural language into two or more different categories can work with this! You can even do regression, such as predicting the score on a 1-10 scale that a user gave, given the text of their review. The preferred input format is either a CSV or newline-delimited JSON file that contains a `sentence1` and `label` field. If your task involves comparing two texts (for example, if your classifier is deciding whether two sentences are paraphrases of each other, or were written by the same author) then you should also include a `sentence2` field in each example. If you do not have a `sentence1` field then the script will assume the non-label fields are the input text, which may not always be what you want, especially if you have more than two fields! Here is a snippet of a valid input JSON file, though note that your texts can be much longer than these, and are not constrained (despite the field name) to being single grammatical sentences: ```json {"sentence1": "COVID-19 vaccine updates: How is the rollout proceeding?", "label": "news"} {"sentence1": "Manchester United celebrates Europa League success", "label": "sports"} ``` ### Usage notes If your inputs are long (more than ~60-70 words), you may wish to increase the `--max_seq_length` argument beyond the default value of 128. The maximum supported value for most models is 512 (about 200-300 words), and some can handle even longer. This will come at a cost in runtime and memory use, however. We assume that your labels represent *categories*, even if they are integers, since text classification is a much more common task than text regression. If your labels are floats, however, the script will assume you want to do regression. This is something you can edit yourself if your use-case requires it! After training, the model will be saved to `--output_dir`. Once your model is trained, you can get predictions by calling the script without a `--train_file` or `--validation_file`; simply pass it the output_dir containing the trained model and a `--test_file` and it will write its predictions to a text file for you. ### Multi-GPU and TPU usage By default, the script uses a `MirroredStrategy` and will use multiple GPUs effectively if they are available. TPUs can also be used by passing the name of the TPU resource with the `--tpu` argument. ### Memory usage and data loading One thing to note is that all data is loaded into memory in this script. Most text classification datasets are small enough that this is not an issue, but if you have a very large dataset you will need to modify the script to handle data streaming. This is particularly challenging for TPUs, given the stricter requirements and the sheer volume of data required to keep them fed. A full explanation of all the possible pitfalls is a bit beyond this example script and README, but for more information you can see the 'Input Datasets' section of [this document](https://www.tensorflow.org/guide/tpu). ### Example command ```bash python run_text_classification.py \ --model_name_or_path distilbert/distilbert-base-cased \ --train_file training_data.json \ --validation_file validation_data.json \ --output_dir output/ \ --test_file data_to_predict.json \ --do_train \ --do_eval \ --do_predict ``` ## run_glue.py This script handles training on the GLUE dataset for various text classification and regression tasks. The GLUE datasets will be loaded automatically, so you only need to specify the task you want (with the `--task_name` argument). You can also supply your own files for prediction with the `--predict_file` argument, for example if you want to train a model on GLUE for e.g. paraphrase detection and then predict whether your own data contains paraphrases or not. Please ensure the names of your input fields match the names of the features in the relevant GLUE dataset - you can see a list of the column names in the `task_to_keys` dict in the `run_glue.py` file. ### Usage notes The `--do_train`, `--do_eval` and `--do_predict` arguments control whether training, evaluations or predictions are performed. After training, the model will be saved to `--output_dir`. Once your model is trained, you can call the script without the `--do_train` or `--do_eval` arguments to quickly get predictions from your saved model. ### Multi-GPU and TPU usage By default, the script uses a `MirroredStrategy` and will use multiple GPUs effectively if they are available. TPUs can also be used by passing the name of the TPU resource with the `--tpu` argument. ### Memory usage and data loading One thing to note is that all data is loaded into memory in this script. Most text classification datasets are small enough that this is not an issue, but if you have a very large dataset you will need to modify the script to handle data streaming.

The warning *Weights from XXX not used in YYY* means that the layer XXX is not used by YYY, therefore those weights are discarded. Parameters: pretrained_model_name_or_path (`str`, *optional*): Can be either: - A string, the *model id* of a pretrained model hosted inside a model repo on huggingface.co. - A path to a *directory* containing model weights saved using [`~TFPreTrainedModel.save_pretrained`], e.g., `./my_model_directory/`. - A path or url to a *PyTorch state_dict save file* (e.g, `./pt_model/pytorch_model.bin`). In this case, `from_pt` should be set to `True` and a configuration object should be provided as `config` argument. This loading path is slower than converting the PyTorch model in a TensorFlow model using the provided conversion scripts and loading the TensorFlow model afterwards. - `None` if you are both providing the configuration and state dictionary (resp. with keyword arguments `config` and `state_dict`). model_args (sequence of positional arguments, *optional*): All remaining positional arguments will be passed to the underlying model's `__init__` method. config (`Union[PretrainedConfig, str]`, *optional*): Can be either: - an instance of a class derived from [`PretrainedConfig`], - a string valid as input to [`~PretrainedConfig.from_pretrained`]. Configuration for the model to use instead of an automatically loaded configuration. Configuration can be automatically loaded when: - The model is a model provided by the library (loaded with the *model id* string of a pretrained model). - The model was saved using [`~TFPreTrainedModel.save_pretrained`] and is reloaded by supplying the save directory. - The model is loaded by supplying a local directory as `pretrained_model_name_or_path` and a configuration JSON file named *config.json* is found in the directory. from_pt (`bool`, *optional*, defaults to `False`): Load the model weights from a PyTorch state_dict save file (see docstring of `pretrained_model_name_or_path` argument). ignore_mismatched_sizes (`bool`, *optional*, defaults to `False`): Whether or not to raise an error if some of the weights from the checkpoint do not have the same size as the weights of the model (if for instance, you are instantiating a model with 10 labels from a checkpoint with 3 labels). cache_dir (`str`, *optional*): Path to a directory in which a downloaded pretrained model configuration should be cached if the standard cache should not be used. force_download (`bool`, *optional*, defaults to `False`): Whether or not to force the (re-)download of the model weights and configuration files, overriding the cached versions if they exist. resume_download: Deprecated and ignored. All downloads are now resumed by default when possible. Will be removed in v5 of Transformers. proxies: (`Dict[str, str], `optional`): A dictionary of proxy servers to use by protocol or endpoint, e.g., `{'http': 'foo.bar:3128', 'http://hostname': 'foo.bar:4012'}`. The proxies are used on each request. output_loading_info(`bool`, *optional*, defaults to `False`): Whether ot not to also return a dictionary containing missing keys, unexpected keys and error messages. local_files_only(`bool`, *optional*, defaults to `False`): Whether or not to only look at local files (e.g., not try downloading the model). token (`str` or `bool`, *optional*): The token to use as HTTP bearer authorization for remote files. If `True`, or not specified, will use the token generated when running `huggingface-cli login` (stored in `~/.huggingface`). revision (`str`, *optional*, defaults to `"main"`): The specific model version to use. It can be a branch name, a tag name, or a commit id, since we use a git-based system for storing models and other artifacts on huggingface.co, so `revision` can be any identifier allowed by git. <Tip> To test a pull request you made on the Hub, you can pass `revision="refs/pr/<pr_number>". </Tip> mirror (`str`, *optional*): Mirror source to accelerate downloads in China. If you are from China and have an accessibility problem, you can set this option to resolve it. Note that we do not guarantee the timeliness or safety. Please refer to the mirror site for more information. subfolder (`str`, *optional*, defaults to `""`): In case the relevant files are located inside a subfolder of the model repo on huggingface.co, you can specify the folder name here. tf_to_pt_weight_rename (`Callable`, *optional*): A function that is called to transform the names of weights during the PyTorch to TensorFlow crossloading process. This is not necessary for most models, but is useful to allow composite models to be crossloaded correctly. use_safetensors (`bool`, *optional*, defaults to `None`): Whether or not to use `safetensors` checkpoints. Defaults to `None`. If not specified and `safetensors` is not installed, it will be set to `False`. kwargs (remaining dictionary of keyword arguments, *optional*): Can be used to update the configuration object (after it being loaded) and initiate the model (e.g., `output_attentions=True`). Behaves differently depending on whether a `config` is provided or automatically loaded: - If a configuration is provided with `config`, `**kwargs` will be directly passed to the underlying model's `__init__` method (we assume all relevant updates to the configuration have already been done) - If a configuration is not provided, `kwargs` will be first passed to the configuration class initialization function ([`~PretrainedConfig.from_pretrained`]). Each key of `kwargs` that corresponds to a configuration attribute will be used to override said attribute with the supplied `kwargs` value. Remaining keys that do not correspond to any configuration attribute will be passed to the underlying model's `__init__` function.

The value of this argument defines the number of overlapping tokens. pad_to_multiple_of (`int`, *optional*): If set will pad the sequence to a multiple of the provided value.

Based on byte-level Byte-Pair-Encoding (BPE). This tokenizer can be used to flatten one or more table(s) and concatenate them with one or more related sentences to be used by TAPEX models. The format that the TAPEX tokenizer creates is the following: sentence col: col1 | col2 | col 3 row 1 : val1 | val2 | val3 row 2 : ... The tokenizer supports a single table + single query, a single table and multiple queries (in which case the table will be duplicated for every query), a single query and multiple tables (in which case the query will be duplicated for every table), and multiple tables and queries. In other words, you can provide a batch of tables + questions to the tokenizer for instance to prepare them for the model. Tokenization itself is based on the BPE algorithm. It is identical to the one used by BART, RoBERTa and GPT-2. This tokenizer inherits from [`PreTrainedTokenizer`] which contains most of the main methods. Users should refer to this superclass for more information regarding those methods. Args: vocab_file (`str`): Path to the vocabulary file. merges_file (`str`): Path to the merges file. do_lower_case (`bool`, *optional*, defaults to `True`): Whether or not to lowercase the input when tokenizing. errors (`str`, *optional*, defaults to `"replace"`): Paradigm to follow when decoding bytes to UTF-8. See [bytes.decode](https://docs.python.org/3/library/stdtypes.html#bytes.decode) for more information. bos_token (`str`, *optional*, defaults to `"<s>"`): The beginning of sequence token that was used during pretraining. Can be used a sequence classifier token. <Tip> When building a sequence using special tokens, this is not the token that is used for the beginning of sequence. The token used is the `cls_token`. </Tip> eos_token (`str`, *optional*, defaults to `"</s>"`): The end of sequence token. <Tip> When building a sequence using special tokens, this is not the token that is used for the end of sequence. The token used is the `sep_token`. </Tip> sep_token (`str`, *optional*, defaults to `"</s>"`): The separator token, which is used when building a sequence from multiple sequences, e.g. two sequences for sequence classification or for a text and a question for question answering. It is also used as the last token of a sequence built with special tokens. cls_token (`str`, *optional*, defaults to `"<s>"`): The classifier token which is used when doing sequence classification (classification of the whole sequence instead of per-token classification). It is the first token of the sequence when built with special tokens. unk_token (`str`, *optional*, defaults to `"<unk>"`): The unknown token. A token that is not in the vocabulary cannot be converted to an ID and is set to be this token instead. pad_token (`str`, *optional*, defaults to `"<pad>"`): The token used for padding, for example when batching sequences of different lengths. mask_token (`str`, *optional*, defaults to `"<mask>"`): The token used for masking values. This is the token used when training this model with masked language modeling. This is the token which the model will try to predict. add_prefix_space (`bool`, *optional*, defaults to `False`): Whether or not to add an initial space to the input. This allows to treat the leading word just as any other word. (BART tokenizer detect beginning of words by the preceding space). max_cell_length (`int`, *optional*, defaults to 15): Maximum number of characters per cell when linearizing a table.

Check the superclass documentation for the generic methods the library implements for all its model (such as downloading or saving, resizing the input embeddings, pruning heads etc.) This model is also a [keras.Model](https://www.tensorflow.org/api_docs/python/tf/keras/Model) subclass. Use it as a regular TF 2.0 Keras Model and refer to the TF 2.0 documentation for all matter related to general usage and behavior. <Tip> TensorFlow models and layers in `transformers` accept two formats as input: - having all inputs as keyword arguments (like PyTorch models), or - having all inputs as a list, tuple or dict in the first positional argument. The reason the second format is supported is that Keras methods prefer this format when passing inputs to models and layers. Because of this support, when using methods like `model.fit()` things should "just work" for you - just pass your inputs and labels in any format that `model.fit()` supports! If, however, you want to use the second format outside of Keras methods like `fit()` and `predict()`, such as when creating your own layers or models with the Keras `Functional` API, there are three possibilities you can use to gather all the input Tensors in the first positional argument: - a single Tensor with `input_ids` only and nothing else: `model(input_ids)` - a list of varying length with one or several input Tensors IN THE ORDER given in the docstring: `model([input_ids, attention_mask])` or `model([input_ids, attention_mask, token_type_ids])` - a dictionary with one or several input Tensors associated to the input names given in the docstring: `model({"input_ids": input_ids, "token_type_ids": token_type_ids})` Note that when creating models and layers with [subclassing](https://keras.io/guides/making_new_layers_and_models_via_subclassing/) then you don't need to worry about any of this, as you can just pass inputs like you would to any other Python function! </Tip> Parameters: config ([`ElectraConfig`]): Model configuration class with all the parameters of the model.

It is used to instantiate an Gemma2 model according to the specified arguments, defining the model architecture. Instantiating a configuration with the defaults will yield a similar configuration to that of the Gemma2-7B. e.g. [google/gemma2-7b](https://huggingface.co/google/gemma2-7b) Configuration objects inherit from [`PretrainedConfig`] and can be used to control the model outputs. Read the documentation from [`PretrainedConfig`] for more information. Args: vocab_size (`int`, *optional*, defaults to 256000): Vocabulary size of the Gemma2 model. Defines the number of different tokens that can be represented by the `inputs_ids` passed when calling [`Gemma2Model`] hidden_size (`int`, *optional*, defaults to 3072): Dimension of the hidden representations. intermediate_size (`int`, *optional*, defaults to 24576): Dimension of the MLP representations. num_hidden_layers (`int`, *optional*, defaults to 28): Number of hidden layers in the Transformer decoder. num_attention_heads (`int`, *optional*, defaults to 16): Number of attention heads for each attention layer in the Transformer decoder. num_key_value_heads (`int`, *optional*, defaults to 16): This is the number of key_value heads that should be used to implement Grouped Query Attention. If `num_key_value_heads=num_attention_heads`, the model will use Multi Head Attention (MHA), if `num_key_value_heads=1` the model will use Multi Query Attention (MQA) otherwise GQA is used. When converting a multi-head checkpoint to a GQA checkpoint, each group key and value head should be constructed by meanpooling all the original heads within that group. For more details checkout [this paper](https://arxiv.org/pdf/2305.13245.pdf). If it is not specified, will default to `num_attention_heads`. head_dim (`int`, *optional*, defaults to 256): The attention head dimension. hidden_activation (`str` or `function`, *optional*, defaults to `"gelu_pytorch_tanh"`): The non-linear activation function (function or string) in the decoder. max_position_embeddings (`int`, *optional*, defaults to 8192): The maximum sequence length that this model might ever be used with. initializer_range (`float`, *optional*, defaults to 0.02): The standard deviation of the truncated_normal_initializer for initializing all weight matrices. rms_norm_eps (`float`, *optional*, defaults to 1e-06): The epsilon used by the rms normalization layers. use_cache (`bool`, *optional*, defaults to `True`): Whether or not the model should return the last key/values attentions (not used by all models). Only relevant if `config.is_decoder=True`. pad_token_id (`int`, *optional*, defaults to 0): Padding token id. eos_token_id (`int`, *optional*, defaults to 1): End of stream token id. bos_token_id (`int`, *optional*, defaults to 2): Beginning of stream token id. tie_word_embeddings (`bool`, *optional*, defaults to `True`): Whether to tie weight embeddings rope_theta (`float`, *optional*, defaults to 10000.0): The base period of the RoPE embeddings. attention_bias (`bool`, defaults to `False`, *optional*, defaults to `False`): Whether to use a bias in the query, key, value and output projection layers during self-attention. attention_dropout (`float`, *optional*, defaults to 0.0): The dropout ratio for the attention probabilities. final_logit_softcapping (`float`, *optional*, defaults to 30.0): scaling factor when applying tanh softcapping on the logits. attn_logit_softcapping (`float`, *optional*, defaults to 50.0): scaling factor when applying tanh softcapping on the attention scores. query_pre_attn_scalar (`float`, *optional*, defaults to 224): scaling factor used on the attention scores sliding_window (`int`, *optional*, defaults to 4096): in Gemma2, every other layer uses sliding window attention. This is the size of the sliding window. ```python >>> from transformers import Gemma2Model, Gemma2Config >>> # Initializing a Gemma2 gemma2-9b style configuration >>> configuration = Gemma2Config() >>> # Initializing a model from the gemma2-9b style configuration >>> model = Gemma2Model(configuration) >>> # Accessing the model configuration >>> configuration = model.config ```""" model_type = "gemma2" keys_to_ignore_at_inference = ["past_key_values"] def __init__( self, vocab_size=256000, hidden_size=3072, intermediate_size=24576, num_hidden_layers=28, num_attention_heads=16, num_key_value_heads=16, head_dim=256, hidden_activation="gelu_pytorch_tanh", max_position_embeddings=8192, initializer_range=0.02, rms_norm_eps=1e-6, use_cache=True, pad_token_id=0, eos_token_id=1, bos_token_id=2, tie_word_embeddings=True, rope_theta=10000.0, attention_bias=False, attention_dropout=0.0, final_logit_softcapping=30.0, attn_logit_softcapping=50.0, query_pre_attn_scalar=224, sliding_window=4096, **kwargs, ): self.vocab_size = vocab_size self.max_position_embeddings = max_position_embeddings self.hidden_size = hidden_size self.intermediate_size = intermediate_size self.num_hidden_layers = num_hidden_layers self.num_attention_heads = num_attention_heads self.head_dim = head_dim self.num_key_value_heads = num_key_value_heads self.hidden_activation = hidden_activation self.initializer_range = initializer_range self.rms_norm_eps = rms_norm_eps self.use_cache = use_cache self.rope_theta = rope_theta self.attention_bias = attention_bias self.attention_dropout = attention_dropout self.attn_logit_softcapping = attn_logit_softcapping super().__init__( pad_token_id=pad_token_id, bos_token_id=bos_token_id, eos_token_id=eos_token_id, tie_word_embeddings=tie_word_embeddings, **kwargs, ) self.final_logit_softcapping = final_logit_softcapping self.query_pre_attn_scalar = query_pre_attn_scalar self.sliding_window = sliding_window self.cache_implementation = "hybrid"

Use it as a regular PyTorch Module and refer to the PyTorch documentation for all matter related to general usage and behavior. Parameters: config ([`GPTNeoConfig`]): Model configuration class with all the parameters of the model. Initializing with a config file does not load the weights associated with the model, only the configuration. Check out the [`~PreTrainedModel.from_pretrained`] method to load the model weights. """ GPT_NEO_INPUTS_DOCSTRING = r""" Args: input_ids (`torch.LongTensor` of shape `(batch_size, input_ids_length)`): `input_ids_length` = `sequence_length` if `past_key_values` is `None` else `past_key_values[0][0].shape[-2]` (`sequence_length` of input past key value states). Indices of input sequence tokens in the vocabulary. If `past_key_values` is used, only `input_ids` that do not have their past calculated should be passed as `input_ids`. Indices can be obtained using [`AutoTokenizer`]. See [`PreTrainedTokenizer.encode`] and [`PreTrainedTokenizer.__call__`] for details. [What are input IDs?](../glossary#input-ids) past_key_values (`Cache` or `tuple(tuple(torch.FloatTensor))`, *optional*): Pre-computed hidden-states (key and values in the self-attention blocks and in the cross-attention blocks) that can be used to speed up sequential decoding. This typically consists in the `past_key_values` returned by the model at a previous stage of decoding, when `use_cache=True` or `config.use_cache=True`. Two formats are allowed: - a [`~cache_utils.Cache`] instance; - Tuple of `tuple(torch.FloatTensor)` of length `config.n_layers`, with each tuple having 2 tensors of shape `(batch_size, num_heads, sequence_length, embed_size_per_head)`). This is also known as the legacy cache format. The model will output the same cache format that is fed as input. If no `past_key_values` are passed, the legacy cache format will be returned. If `past_key_values` are used, the user can optionally input only the last `input_ids` (those that don't have their past key value states given to this model) of shape `(batch_size, 1)` instead of all `input_ids` of shape `(batch_size, sequence_length)`. attention_mask (`torch.FloatTensor` of shape `(batch_size, sequence_length)`, *optional*): Mask to avoid performing attention on padding token indices. Mask values selected in `[0, 1]`: - 1 for tokens that are **not masked**, - 0 for tokens that are **masked**. [What are attention masks?](../glossary#attention-mask) token_type_ids (`torch.LongTensor` of shape `(batch_size, input_ids_length)`, *optional*): Segment token indices to indicate first and second portions of the inputs. Indices are selected in `[0, 1]`: - 0 corresponds to a *sentence A* token, - 1 corresponds to a *sentence B* token. [What are token type IDs?](../glossary#token-type-ids) position_ids (`torch.LongTensor` of shape `(batch_size, sequence_length)`, *optional*): Indices of positions of each input sequence tokens in the position embeddings. Selected in the range `[0, config.max_position_embeddings - 1]`. [What are position IDs?](../glossary#position-ids) head_mask (`torch.FloatTensor` of shape `(num_heads,)` or `(num_layers, num_heads)`, *optional*): Mask to nullify selected heads of the self-attention modules. Mask values selected in `[0, 1]`: - 1 indicates the head is **not masked**, - 0 indicates the head is **masked**. inputs_embeds (`torch.FloatTensor` of shape `(batch_size, sequence_length, hidden_size)`, *optional*): Optionally, instead of passing `input_ids` you can choose to directly pass an embedded representation. This is useful if you want more control over how to convert `input_ids` indices into associated vectors than the model's internal embedding lookup matrix. If `past_key_values` is used, optionally only the last `inputs_embeds` have to be input (see `past_key_values`). use_cache (`bool`, *optional*): If set to `True`, `past_key_values` key value states are returned and can be used to speed up decoding (see `past_key_values`). output_attentions (`bool`, *optional*): Whether or not to return the attentions tensors of all attention layers. See `attentions` under returned tensors for more detail. output_hidden_states (`bool`, *optional*): Whether or not to return the hidden states of all layers. See `hidden_states` under returned tensors for more detail. return_dict (`bool`, *optional*): Whether or not to return a [`~utils.ModelOutput`] instead of a plain tuple. cache_position (`torch.LongTensor` of shape `(sequence_length)`, *optional*): Indices depicting the position of the input sequence tokens in the sequence. Contrarily to `position_ids`, this tensor is not affected by padding. It is used to update the cache in the correct position and to infer the complete sequence length.

Check the superclass documentation for the generic methods the library implements for all its model (such as downloading or saving, resizing the input embeddings, pruning heads etc.) This model is also a [keras.Model](https://www.tensorflow.org/api_docs/python/tf/keras/Model) subclass. Use it as a regular TF 2.0 Keras Model and refer to the TF 2.0 documentation for all matter related to general usage and behavior. <Tip> TensorFlow models and layers in `transformers` accept two formats as input: - having all inputs as keyword arguments (like PyTorch models), or - having all inputs as a list, tuple or dict in the first positional argument. The reason the second format is supported is that Keras methods prefer this format when passing inputs to models and layers. Because of this support, when using methods like `model.fit()` things should "just work" for you - just pass your inputs and labels in any format that `model.fit()` supports! If, however, you want to use the second format outside of Keras methods like `fit()` and `predict()`, such as when creating your own layers or models with the Keras `Functional` API, there are three possibilities you can use to gather all the input Tensors in the first positional argument: - a single Tensor with `input_ids` only and nothing else: `model(input_ids)` - a list of varying length with one or several input Tensors IN THE ORDER given in the docstring: `model([input_ids, attention_mask])` or `model([input_ids, attention_mask, token_type_ids])` - a dictionary with one or several input Tensors associated to the input names given in the docstring: `model({"input_ids": input_ids, "token_type_ids": token_type_ids})` Note that when creating models and layers with [subclassing](https://keras.io/guides/making_new_layers_and_models_via_subclassing/) then you don't need to worry about any of this, as you can just pass inputs like you would to any other Python function! </Tip> Parameters: config ([`GPTJConfig`]): Model configuration class with all the parameters of the model.

Based on [SentencePiece](https://github.com/google/sentencepiece). This tokenizer inherits from [`PreTrainedTokenizer`] which contains most of the main methods. Users should refer to this superclass for more information regarding those methods. Args: vocab_file (`str`): Path to the vocabulary file. src_lang (`str`, *optional*): A string representing the source language. tgt_lang (`str`, *optional*): A string representing the target language. eos_token (`str`, *optional*, defaults to `"</s>"`): The end of sequence token. sep_token (`str`, *optional*, defaults to `"</s>"`): The separator token, which is used when building a sequence from multiple sequences, e.g. two sequences for sequence classification or for a text and a question for question answering. It is also used as the last token of a sequence built with special tokens. cls_token (`str`, *optional*, defaults to `"<s>"`): The classifier token which is used when doing sequence classification (classification of the whole sequence instead of per-token classification). It is the first token of the sequence when built with special tokens. unk_token (`str`, *optional*, defaults to `"<unk>"`): The unknown token. A token that is not in the vocabulary cannot be converted to an ID and is set to be this token instead. pad_token (`str`, *optional*, defaults to `"<pad>"`): The token used for padding, for example when batching sequences of different lengths. mask_token (`str`, *optional*, defaults to `"<mask>"`): The token used for masking values. This is the token used when training this model with masked language modeling. This is the token which the model will try to predict. sp_model_kwargs (`dict`, *optional*): Will be passed to the `SentencePieceProcessor.__init__()` method. The [Python wrapper for SentencePiece](https://github.com/google/sentencepiece/tree/master/python) can be used, among other things, to set: - `enable_sampling`: Enable subword regularization. - `nbest_size`: Sampling parameters for unigram. Invalid for BPE-Dropout. - `nbest_size = {0,1}`: No sampling is performed. - `nbest_size > 1`: samples from the nbest_size results. - `nbest_size < 0`: assuming that nbest_size is infinite and samples from the all hypothesis (lattice) using forward-filtering-and-backward-sampling algorithm. - `alpha`: Smoothing parameter for unigram sampling, and dropout probability of merge operations for BPE-dropout. Examples: ```python >>> from transformers import MBart50Tokenizer >>> tokenizer = MBart50Tokenizer.from_pretrained("facebook/mbart-large-50", src_lang="en_XX", tgt_lang="ro_RO") >>> src_text = " UN Chief Says There Is No Military Solution in Syria" >>> tgt_text = "Şeful ONU declară că nu există o soluţie militară în Siria" >>> model_inputs = tokenizer(src_text, text_target=tgt_text, return_tensors="pt") >>> # model(**model_inputs) should work ```""" vocab_files_names = VOCAB_FILES_NAMES model_input_names = ["input_ids", "attention_mask"] prefix_tokens: List[int] = [] suffix_tokens: List[int] = [] def __init__( self, vocab_file, src_lang=None, tgt_lang=None, eos_token="</s>", sep_token="</s>", cls_token="<s>", unk_token="<unk>", pad_token="<pad>", mask_token="<mask>", sp_model_kwargs: Optional[Dict[str, Any]] = None, **kwargs, ) -> None: # Mask token behave like a normal word, i.e. include the space before it mask_token = AddedToken(mask_token, lstrip=True, rstrip=False) if isinstance(mask_token, str) else mask_token self.sp_model_kwargs = {} if sp_model_kwargs is None else sp_model_kwargs kwargs["additional_special_tokens"] = kwargs.get("additional_special_tokens", []) or [] kwargs["additional_special_tokens"] += [ code for code in FAIRSEQ_LANGUAGE_CODES if code not in kwargs["additional_special_tokens"] ] self.sp_model = spm.SentencePieceProcessor(**self.sp_model_kwargs) self.sp_model.Load(str(vocab_file)) self.vocab_file = vocab_file # Original fairseq vocab and spm vocab must be "aligned": # Vocab | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 # -------- | ------- | ------- | ------ | ------- | --- | --- | --- | ----- | ----- | ---- # fairseq | '<s>' | '<pad>' | '</s>' | '<unk>' | ',' | '.' | '▁' | 's' | '▁de' | '-' # spm | '<unk>' | '<s>' | '</s>' | ',' | '.' | '▁' | 's' | '▁de' | '-' | '▁a' # Mimic fairseq token-to-id alignment for the first 4 token self.fairseq_tokens_to_ids = {"<s>": 0, "<pad>": 1, "</s>": 2, "<unk>": 3} # The first "real" token "," has position 4 in the original fairseq vocab and position 3 in the spm vocab self.fairseq_offset = 1 self.sp_model_size = len(self.sp_model) self.lang_code_to_id = { code: self.sp_model_size + i + self.fairseq_offset for i, code in enumerate(FAIRSEQ_LANGUAGE_CODES) } self.id_to_lang_code = {v: k for k, v in self.lang_code_to_id.items()} self.fairseq_tokens_to_ids["<mask>"] = len(self.sp_model) + len(self.lang_code_to_id) + self.fairseq_offset self.fairseq_tokens_to_ids.update(self.lang_code_to_id) self.fairseq_ids_to_tokens = {v: k for k, v in self.fairseq_tokens_to_ids.items()} super().__init__( src_lang=src_lang, tgt_lang=tgt_lang, eos_token=eos_token, unk_token=unk_token, sep_token=sep_token, cls_token=cls_token, pad_token=pad_token, mask_token=mask_token, sp_model_kwargs=self.sp_model_kwargs, **kwargs, ) self._src_lang = src_lang if src_lang is not None else "en_XX" self.cur_lang_code_id = self.lang_code_to_id[self._src_lang] self.tgt_lang = tgt_lang self.set_src_lang_special_tokens(self._src_lang) @property def vocab_size(self) -> int: return len(self.sp_model) + len(self.lang_code_to_id) + self.fairseq_offset + 1 # Plus 1 for the mask token @property def src_lang(self) -> str: return self._src_lang @src_lang.setter def src_lang(self, new_src_lang: str) -> None: self._src_lang = new_src_lang self.set_src_lang_special_tokens(self._src_lang) def __getstate__(self) -> Dict: state = self.__dict__.copy() state["sp_model"] = None return state def __setstate__(self, d: Dict) -> None: self.__dict__ = d # for backward compatibility if not hasattr(self, "sp_model_kwargs"): self.sp_model_kwargs = {} self.sp_model = spm.SentencePieceProcessor(**self.sp_model_kwargs) self.sp_model.Load(self.vocab_file) def get_vocab(self) -> Dict: vocab = {self.convert_ids_to_tokens(i): i for i in range(self.vocab_size)} vocab.update(self.added_tokens_encoder) return vocab def _tokenize(self, text: str) -> List[str]: return self.sp_model.encode(text, out_type=str) def _convert_token_to_id(self, token: str) -> int: """Converts a token (str) in an id using the vocab.""" if token in self.fairseq_tokens_to_ids: return self.fairseq_tokens_to_ids[token] spm_id = self.sp_model.PieceToId(token) # Need to return unknown token if the SP model returned 0 return spm_id + self.fairseq_offset if spm_id else self.unk_token_id def _convert_id_to_token(self, index: int) -> str: """Converts an index (integer) in a token (str) using the vocab.""" if index in self.fairseq_ids_to_tokens: return self.fairseq_ids_to_tokens[index] return self.sp_model.IdToPiece(index -

It is used to instantiate a Qwen2-VL model according to the specified arguments, defining the model architecture. Instantiating a configuration with the defaults will yield a similar configuration to that of Qwen2-VL-7B-Instruct [Qwen/Qwen2-VL-7B-Instruct](https://huggingface.co/Qwen/Qwen2-VL-7B-Instruct). Configuration objects inherit from [`PretrainedConfig`] and can be used to control the model outputs. Read the documentation from [`PretrainedConfig`] for more information. Args: vocab_size (`int`, *optional*, defaults to 152064): Vocabulary size of the Qwen2VL model. Defines the number of different tokens that can be represented by the `inputs_ids` passed when calling [`Qwen2VLModel`] hidden_size (`int`, *optional*, defaults to 8192): Dimension of the hidden representations. intermediate_size (`int`, *optional*, defaults to 29568): Dimension of the MLP representations. num_hidden_layers (`int`, *optional*, defaults to 80): Number of hidden layers in the Transformer encoder. num_attention_heads (`int`, *optional*, defaults to 64): Number of attention heads for each attention layer in the Transformer encoder. num_key_value_heads (`int`, *optional*, defaults to 8): This is the number of key_value heads that should be used to implement Grouped Query Attention. If `num_key_value_heads=num_attention_heads`, the model will use Multi Head Attention (MHA), if `num_key_value_heads=1` the model will use Multi Query Attention (MQA) otherwise GQA is used. When converting a multi-head checkpoint to a GQA checkpoint, each group key and value head should be constructed by meanpooling all the original heads within that group. For more details checkout [this paper](https://arxiv.org/pdf/2305.13245.pdf). If it is not specified, will default to `32`. hidden_act (`str` or `function`, *optional*, defaults to `"silu"`): The non-linear activation function (function or string) in the decoder. max_position_embeddings (`int`, *optional*, defaults to 32768): The maximum sequence length that this model might ever be used with. initializer_range (`float`, *optional*, defaults to 0.02): The standard deviation of the truncated_normal_initializer for initializing all weight matrices. rms_norm_eps (`float`, *optional*, defaults to 1e-05): The epsilon used by the rms normalization layers. use_cache (`bool`, *optional*, defaults to `True`): Whether or not the model should return the last key/values attentions (not used by all models). Only relevant if `config.is_decoder=True`. tie_word_embeddings (`bool`, *optional*, defaults to `False`): Whether the model's input and output word embeddings should be tied. rope_theta (`float`, *optional*, defaults to 1000000.0): The base period of the RoPE embeddings. use_sliding_window (`bool`, *optional*, defaults to `False`): Whether to use sliding window attention. sliding_window (`int`, *optional*, defaults to 4096): Sliding window attention (SWA) window size. If not specified, will default to `4096`. max_window_layers (`int`, *optional*, defaults to 80): The number of layers that use SWA (Sliding Window Attention). The bottom layers use SWA while the top use full attention. attention_dropout (`float`, *optional*, defaults to 0.0): The dropout ratio for the attention probabilities. vision_config (`Dict`, *optional*): The config for the visual encoder initialization. rope_scaling (`Dict`, *optional*): Dictionary containing the scaling configuration for the RoPE embeddings. Currently supports two scaling strategies: linear and dynamic. Their scaling factor must be a float greater than 1. The expected format is `{"type": strategy name, "factor": scaling factor}`. When using this flag, don't update `max_position_embeddings` to the expected new maximum. See the following thread for more information on how these scaling strategies behave: https://www.reddit.com/r/LocalLLaMA/comments/14mrgpr/dynamically_scaled_rope_further_increases/.

It's an encoder-decoder T5-like model with sparse Feed Forward that stands for Mixture of Experts (MoE) architecture. This model inherits from [`PreTrainedModel`]. Check the superclass documentation for the generic methods the library implements for all its model (such as downloading or saving, resizing the input embeddings, pruning heads etc.) This model is also a PyTorch [torch.nn.Module](https://pytorch.org/docs/stable/nn.html#torch.nn.Module) subclass. Use it as a regular PyTorch Module and refer to the PyTorch documentation for all matter related to general usage and behavior. Parameters: config ([`SwitchTransformersConfig`]): Model configuration class with all the parameters of the model. Initializing with a config file does not load the weights associated with the model, only the configuration. Check out the [`~PreTrainedModel.from_pretrained`] method to load the model weights.

Accepts the following values: - `True` or `'longest_first'`: Truncate to a maximum length specified with the argument `max_length` or to the maximum acceptable input length for the model if that argument is not provided. This will truncate token by token, removing a token from the longest sequence in the pair if a pair of sequences (or a batch of pairs) is provided. - `'only_first'`: Truncate to a maximum length specified with the argument `max_length` or to the maximum acceptable input length for the model if that argument is not provided. This will only truncate the first sequence of a pair if a pair of sequences (or a batch of pairs) is provided. - `'only_second'`: Truncate to a maximum length specified with the argument `max_length` or to the maximum acceptable input length for the model if that argument is not provided.

If left unset or set to `None`, this will use the predefined model maximum length if a maximum length is required by one of the truncation/padding parameters. If the model has no specific maximum input length (like XLNet) truncation/padding to a maximum length will be deactivated. stride (`int`, *optional*, defaults to 0): If set to a number along with `max_length`, the overflowing tokens returned when `return_overflowing_tokens=True` will contain some tokens from the end of the truncated sequence returned to provide some overlap between truncated and overflowing sequences.

Based on [SentencePiece](https://github.com/google/sentencepiece). This tokenizer inherits from [`PreTrainedTokenizer`] which contains most of the main methods. Users should refer to this superclass for more information regarding those methods. Args: vocab_file (`str`): Path to the vocabulary file. eos_token (`str`, *optional*, defaults to `"</s>"`): The end of sequence token. <Tip> When building a sequence using special tokens, this is not the token that is used for the end of sequence. The token used is the `sep_token`. </Tip> unk_token (`str`, *optional*, defaults to `"<unk>"`): The unknown token. A token that is not in the vocabulary cannot be converted to an ID and is set to be this token instead. sep_token (`str`, *optional*, defaults to `"</s>"`): The separator token, which is used when building a sequence from multiple sequences, e.g. two sequences for sequence classification or for a text and a question for question answering. It is also used as the last token of a sequence built with special tokens. pad_token (`str`, *optional*, defaults to `"<pad>"`): The token used for padding, for example when batching sequences of different lengths. sep_token_box (`List[int]`, *optional*, defaults to `[1000, 1000, 1000, 1000]`): The bounding box to use for the special [SEP] token. pad_token_box (`List[int]`, *optional*, defaults to `[0, 0, 0, 0]`): The bounding box to use for the special [PAD] token. pad_token_label (`int`, *optional*, defaults to -100): The label to use for padding tokens. Defaults to -100, which is the `ignore_index` of PyTorch's CrossEntropyLoss. only_label_first_subword (`bool`, *optional*, defaults to `True`): Whether or not to only label the first subword, in case word labels are provided. additional_special_tokens (`List[str]`, *optional*, defaults to `["<s>NOTUSED", "</s>NOTUSED"]`): Additional special tokens used by the tokenizer. sp_model_kwargs (`dict`, *optional*): Will be passed to the `SentencePieceProcessor.__init__()` method. The [Python wrapper for SentencePiece](https://github.com/google/sentencepiece/tree/master/python) can be used, among other things, to set: - `enable_sampling`: Enable subword regularization. - `nbest_size`: Sampling parameters for unigram. Invalid for BPE-Dropout. - `nbest_size = {0,1}`: No sampling is performed. - `nbest_size > 1`: samples from the nbest_size results. - `nbest_size < 0`: assuming that nbest_size is infinite and samples from the all hypothesis (lattice) using forward-filtering-and-backward-sampling algorithm. - `alpha`: Smoothing parameter for unigram sampling, and dropout probability of merge operations for BPE-dropout. legacy (`bool`, *optional*, defaults to `True`): Whether or not the `legacy` behaviour of the tokenizer should be used. Legacy is before the merge of #24622 which includes fixes to properly handle tokens that appear after special tokens. A simple example: - `legacy=True`: ```python >>> from transformers import T5Tokenizer >>> tokenizer = T5Tokenizer.from_pretrained("t5-base", legacy=True) >>> tokenizer.encode("Hello <extra_id_0>.") [8774, 32099, 3, 5, 1] ``` - `legacy=False`: ```python >>> from transformers import T5Tokenizer >>> tokenizer = T5Tokenizer.from_pretrained("t5-base", legacy=False) >>> tokenizer.encode("Hello <extra_id_0>.") # the extra space `[3]` is no longer here [8774, 32099, 5, 1] ``` Checkout the pull request and the issue [here](https://github.com/huggingface/transformers/pull/24565) for more details. add_prefix_space (`bool`, *optional*, defaults to `True`): Whether or not to add an initial space to the input.
