State-of-the-art Natural Language Processing for PyTorch and TensorFlow 2.0🤗 Transformers provides thousands of pretrained models to perform tasks on texts such as classification, information extraction, question answering, summarization, translation, text generation, etc in 100+ languages. Its aim is to make cutting-edge NLP easier to use for everyone.🤗 Transformers provides APIs to quickly download and use those pretrained models on a given text, fine-tune them on your own datasets then share them with the community on ourmodel hub. At the same time, each python module defining an architecture can be used as a standalone and modified to enable quick research experiments.🤗 Transformers is backed by the two most popular deep learning libraries,PyTorchandTensorFlow, with a seamless integration between them, allowing you to train your models with one then load it for inference with the other.Online demosYou can test most of our models directly on their pages from themodel hub. We also offerprivate model hosting, versioning, & an inference APIto use those models.Here are a few examples:Masked word completion with BERTName Entity Recognition with ElectraText generation with GPT-2Natural Language Inference with RoBERTaSummarization with BARTQuestion answering with DistilBERTTranslation with T5Write With Transformer, built by the Hugging Face team, is the official demo of this repo’s text generation capabilities.Quick tourTo immediately use a model on a given text, we provide thepipelineAPI. Pipelines group together a pretrained model with the preprocessing that was used during that model training. Here is how to quickly use a pipeline to classify positive versus negative texts>>>fromtransformersimportpipeline# Allocate a pipeline for sentiment-analysis>>>classifier=pipeline('sentiment-analysis')>>>classifier('We are very happy to include pipeline into the transformers repository.')[{'label':'POSITIVE','score':0.9978193640708923}]The second line of code downloads and caches the pretrained model used by the pipeline, the third line evaluates it on the given text. Here the answer is "positive" with a confidence of 99.8%.This is another example of pipeline used for that can extract question answers from some context:>>>fromtransformersimportpipeline# Allocate a pipeline for question-answering>>>question_answerer=pipeline('question-answering')>>>question_answerer({...'question':'What is the name of the repository ?',...'context':'Pipeline have been included in the huggingface/transformers repository'...}){'score':0.5135612454720828,'start':35,'end':59,'answer':'huggingface/transformers'}On top of the answer, the pretrained model used here returned its confidence score, along with the start position and its end position in the tokenized sentence. You can learn more about the tasks supported by thepipelineAPI inthis tutorial.To download and use any of the pretrained models on your given task, you just need to use those three lines of codes (PyTorch version):>>>fromtransformersimportAutoTokenizer,AutoModel>>>tokenizer=AutoTokenizer.from_pretrained("bert-base-uncased")>>>model=AutoModel.from_pretrained("bert-base-uncased")>>>inputs=tokenizer("Hello world!",return_tensors="pt")>>>outputs=model(**inputs)or for TensorFlow:>>>fromtransformersimportAutoTokenizer,TFAutoModel>>>tokenizer=AutoTokenizer.from_pretrained("bert-base-uncased")>>>model=TFAutoModel.from_pretrained("bert-base-uncased")>>>inputs=tokenizer("Hello world!",return_tensors="tf")>>>outputs=model(**inputs)The tokenizer is responsible for all the preprocessing the pretrained model expects, and can be called directly on one (or list) of texts (as we can see on the fourth line of both code examples). It will output a dictionary you can directly pass to your model (which is done on the fifth line).The model itself is a regularPytorchnn.Moduleor aTensorFlowtf.keras.Model(depending on your backend) which you can use normally. For instance,this tutorialexplains how to integrate such a model in classic PyTorch or TensorFlow training loop, or how to use ourTrainerAPI to quickly fine-tune the on a new dataset.Why should I use transformers?Easy-to-use state-of-the-art models:High performance on NLU and NLG tasks.Low barrier to entry for educators and practitioners.Few user-facing abstractions with just three classes to learn.A unified API for using all our pretrained models.Lower compute costs, smaller carbon footprint:Researchers can share trained models instead of always retraining.Practitioners can reduce compute time and production costs.Dozens of architectures with over 2,000 pretrained models, some in more than 100 languages.Choose the right framework for every part of a model's lifetime:Train state-of-the-art models in 3 lines of code.Move a single model between TF2.0/PyTorch frameworks at will.Seamlessly pick the right framework for training, evaluation, production.Easily customize a model or an example to your needs:Examples for each architecture to reproduce the results by the official authors of said architecture.Expose the models internal as consistently as possible.Model files can be used independently of the library for quick experiments.Why shouldn't I use transformers?This library is not a modular toolbox of building blocks for neural nets. The code in the model files is not refactored with additional abstractions on purpose, so that researchers can quickly iterate on each of the models without diving in additional abstractions/files.The training API is not intended to work on any model but is optimized to work with the models provided by the library. For generic machine learning loops, you should use another library.While we strive to present as many use cases as possible, the scripts in ourexamples folderare just that: examples. It is expected that they won't work out-of-the box on your specific problem and that you will be required to change a few lines of code to adapt them to your needs.InstallationWith pipThis repository is tested on Python 3.6+, PyTorch 1.0.0+ (PyTorch 1.3.1+ forexamples) and TensorFlow 2.0.You should install 🤗 Transformers in avirtual environment. If you're unfamiliar with Python virtual environments, check out theuser guide.First, create a virtual environment with the version of Python you're going to use and activate it.Then, you will need to install at least one of TensorFlow 2.0, PyTorch or Flax.
Please refer toTensorFlow installation page,PyTorch installation pageregarding the specific install command for your platform and/orFlax installation page.When TensorFlow 2.0 and/or PyTorch has been installed, 🤗 Transformers can be installed using pip as follows:pipinstalltransformersIf you'd like to play with the examples or need the bleeding edge of the code and can't wait for a new release, you mustinstall the library from source.With condaSince Transformers version v4.0.0, we now have a conda channel:huggingface.🤗 Transformers can be installed using conda as follows:condainstall-chuggingfacetransformersFollow the installation pages of TensorFlow, PyTorch or Flax to see how to install them with conda.Models architecturesAll the model checkpointsprovided by 🤗 Transformers are seamlessly integrated from the huggingface.comodel hubwhere they are uploaded directly byusersandorganizations.Current number of checkpoints:🤗 Transformers currently provides the following architectures (seeherefor a high-level summary of each them):ALBERT(from Google Research and the Toyota Technological Institute at Chicago) released with the paperALBERT: A Lite BERT for Self-supervised Learning of Language Representations, by Zhenzhong Lan, Mingda Chen, Sebastian Goodman, Kevin Gimpel, Piyush Sharma, Radu Soricut.BART(from Facebook) released with the paperBART: Denoising Sequence-to-Sequence Pre-training for Natural Language Generation, Translation, and Comprehensionby Mike Lewis, Yinhan Liu, Naman Goyal, Marjan Ghazvininejad, Abdelrahman Mohamed, Omer Levy, Ves Stoyanov and Luke Zettlemoyer.BARThez(from École polytechnique) released with the paperBARThez: a Skilled Pretrained French Sequence-to-Sequence Modelby Moussa Kamal Eddine, Antoine J.-P.
