Accepted files are reStructuredText (.rst) and Markdown (.md). Create a file with its extension and put it
in the source directory. You can then link it to the toc-tree by putting the filename without the extension.
## Writing Documentation - Specification
The `huggingface/transformers` documentation follows the
[Google documentation](https://sphinxcontrib-napoleon.readthedocs.io/en/latest/example_google.html) style. It is
mostly written in ReStructuredText
([Sphinx simple documentation](https://www.sphinx-doc.org/en/master/usage/restructuredtext/index.html),
[Sourceforge complete documentation](https://docutils.sourceforge.io/docs/ref/rst/restructuredtext.html))
### Adding a new section
A section is a page held in the `Notes` toc-tree on the documentation. Adding a new section is done in two steps:
- Add a new file under `./source`. This file can either be ReStructuredText (.rst) or Markdown (.md).
- Link that file in `./source/index.rst` on the correct toc-tree.
### Adding a new model
When adding a new model:
- Create a file `xxx.rst` under `./source/model_doc`.
- Link that file in `./source/index.rst` on the `model_doc` toc-tree.
- Write a short overview of the model:
- Overview with paper & authors
- Paper abstract
- Tips and tricks and how to use it best
- Add the classes that should be linked in the model. This generally includes the configuration, the tokenizer, and
every model of that class (the base model, alongside models with additional heads), both in PyTorch and TensorFlow.
The order is generally:
- Configuration,
- Tokenizer
- PyTorch base model
- PyTorch head models
- TensorFlow base model
- TensorFlow head models
These classes should be added using the RST syntax. Usually as follows:
```
XXXConfig
~~~~~~~~~~~~~~~~~~~~~
.. autoclass:: transformers.XXXConfig
:members:
```
This will include every public method of the configuration. If for some reason you wish for a method not to be displayed
in the documentation, you can do so by specifying which methods should be in the docs:
```
XXXTokenizer
~~~~~~~~~~~~~~~~~~~~~
.. autoclass:: transformers.XXXTokenizer
:members: build_inputs_with_special_tokens, get_special_tokens_mask,
create_token_type_ids_from_sequences, save_vocabulary
```
### Writing source documentation
Values that should be put in `code` should either be surrounded by double backticks: \`\`like so\`\` or be written as an object
using the :obj: syntax: :obj:\`like so\`.
When mentionning a class, it is recommended to use the :class: syntax as the mentioned class will be automatically
linked by Sphinx: :class:\`transformers.XXXClass\`
When mentioning a function, it is recommended to use the :func: syntax as the mentioned method will be automatically
linked by Sphinx: :func:\`transformers.XXXClass.method\`
Links should be done as so (note the double underscore at the end): \`text for the link <./local-link-or-global-link#loc>\`__
#### Defining arguments in a method
Arguments should be defined with the `Args:` prefix, followed by a line return and an indentation.
The argument should be followed by its type, with its shape if it is a tensor, and a line return.
Another indentation is necessary before writing the description of the argument.
Here's an example showcasing everything so far:
```
Args:
input_ids (:obj:`torch.LongTensor` of shape :obj:`(batch_size, sequence_length)`):
Indices of input sequence tokens in the vocabulary.
Indices can be obtained using :class:`transformers.AlbertTokenizer`.
See :func:`transformers.PreTrainedTokenizer.encode` and
:func:`transformers.PreTrainedTokenizer.encode_plus` for details.
`What are input IDs? <../glossary.html#input-ids>`__
```
#### Writing a multi-line code block
Multi-line code blocks can be useful for displaying examples. They are done like so:
```
Example::
# first line of code
# second line
# etc
```
The `Example` string at the beginning can be replaced by anything as long as there are two semicolons following it.
#### Writing a return block
Arguments should be defined with the `Args:` prefix, followed by a line return and an indentation.
The first line should be the type of the return, followed by a line return. No need to indent further for the elements
building the return.
Here's an example for tuple return, comprising several objects:
```
Returns:
:obj:`tuple(torch.FloatTensor)` comprising various elements depending on the configuration (:class:`~transformers.BertConfig`) and inputs:
loss (`optional`, returned when ``masked_lm_labels`` is provided) ``torch.FloatTensor`` of shape ``(1,)``:
Total loss as the sum of the masked language modeling loss and the next sequence prediction (classification) loss.
prediction_scores (:obj:`torch.FloatTensor` of shape :obj:`(batch_size, sequence_length, config.vocab_size)`)
Prediction scores of the language modeling head (scores for each vocabulary token before SoftMax).
```
Here's an example for a single value return:
```
Returns:
A list of integers in the range [0, 1]: 1 for a special token, 0 for a sequence token.
```

## Migrating from pytorch-transformers to transformers
Here is a quick summary of what you should take care of when migrating from `pytorch-transformers` to `transformers`.
### Positional order of some models' keywords inputs (`attention_mask`, `token_type_ids`...) changed
To be able to use Torchscript (see #1010, #1204 and #1195) the specific order of some models **keywords inputs** (`attention_mask`, `token_type_ids`...) has been changed.
If you used to call the models with keyword names for keyword arguments, e.g. `model(inputs_ids, attention_mask=attention_mask, token_type_ids=token_type_ids)`, this should not cause any change.
If you used to call the models with positional inputs for keyword arguments, e.g. `model(inputs_ids, attention_mask, token_type_ids)`, you may have to double check the exact order of input arguments.

MarianMT
----------------------------------------------------
**DISCLAIMER:** If you see something strange,
file a `Github Issue <https://github.com/huggingface/transformers/issues/new?assignees=&labels=&template=bug-report.md&title>`__ and assign
@sshleifer. Translations should be similar, but not identical to, output in the test set linked to in each model card.
Implementation Notes
~~~~~~~~~~~~~~~~~~~~
- each model is about 298 MB on disk, there are 1,000+ models.
- The list of supported language pairs can be found `here <https://huggingface.co/Helsinki-NLP>`__.
- The 1,000+ models were originally trained by `Jörg Tiedemann <https://researchportal.helsinki.fi/en/persons/j%C3%B6rg-tiedemann>`__ using the `Marian <https://marian-nmt.github.io/>`_ C++ library, which supports fast training and translation.
- All models are transformer encoder-decoders with 6 layers in each component. Each model's performance is documented in a model card.
- the 80 opus models that require BPE preprocessing are not supported.
- The modeling code is the same as ``BartForConditionalGeneration`` with a few minor modifications:
- static (sinusoid) positional embeddings (``MarianConfig.static_position_embeddings=True``)
- a new final_logits_bias (``MarianConfig.add_bias_logits=True``)
- no layernorm_embedding (``MarianConfig.normalize_embedding=False``)
- the model starts generating with pad_token_id (which has 0 token_embedding) as the prefix. (Bart uses <s/>)
- Code to bulk convert models can be found in ``convert_marian_to_pytorch.py``
Naming
~~~~~~
- All model names use the following format: ``Helsinki-NLP/opus-mt-{src}-{tgt}``
- The language codes used to name models are inconsistent. Two digit codes can usually be found `here <https://developers.google.com/admin-sdk/directory/v1/languages>`_, three digit codes require googling "language code {code}".
- Codes formatted like ``es_AR`` are usually ``code_{region}``. That one is spanish documents from Argentina.
Multilingual Models
~~~~~~~~~~~~~~~~~~~~
All model names use the following format: ``Helsinki-NLP/opus-mt-{src}-{tgt}``:
- if ``src`` is in all caps, the model supports multiple input languages, you can figure out which ones by looking at the model card, or the Group Members `mapping <https://gist.github.com/sshleifer/6d20e7761931b08e73c3219027b97b8a>`_ .
- if ``tgt`` is in all caps, the model can output multiple languages, and you should specify a language code by prepending the desired output language to the src_text
- You can see a tokenizer's supported language codes in ``tokenizer.supported_language_codes``
Example of translating english to many romance languages, using language codes:
.. code-block:: python
from transformers import MarianMTModel, MarianTokenizer
src_text = [
'>>fr<< this is a sentence in english that we want to translate to french',
'>>pt<< This should go to portuguese',
'>>es<< And this to Spanish'
]
model_name = 'Helsinki-NLP/opus-mt-en-ROMANCE'
tokenizer = MarianTokenizer.from_pretrained(model_name)
print(tokenizer.supported_language_codes)
model = MarianMTModel.from_pretrained(model_name)
translated = model.generate(**tokenizer.prepare_translation_batch(src_text))
tgt_text = [tokenizer.decode(t, skip_special_tokens=True) for t in translated]
# ["c'est une phrase en anglais que nous voulons traduire en français",
# 'Isto deve ir para o português.',
# 'Y esto al español']
Sometimes, models were trained on collections of languages that do not resolve to a group. In this case, _ is used as a separator for src or tgt, as in ``'Helsinki-NLP/opus-mt-en_el_es_fi-en_el_es_fi'``. These still require language codes.
There are many supported regional language codes, like ``>>es_ES<<`` (Spain) and ``>>es_AR<<`` (Argentina), that do not seem to change translations. I have not found these to provide different results than just using ``>>es<<``.
For Example:
- ``Helsinki-NLP/opus-mt-NORTH_EU-NORTH_EU``: translates from all NORTH_EU languages (see `mapping <https://gist.github.com/sshleifer/6d20e7761931b08e73c3219027b97b8a>`_) to all NORTH_EU languages. Use a special language code like ``>>de<<`` to specify output language.
- ``Helsinki-NLP/opus-mt-ROMANCE-en``: translates from many romance languages to english, no codes needed since there is only 1 tgt language.

## Main concepts

The library is build around three type of classes for each models:
- **model classes** e.g., `BertModel` which are 20+ PyTorch models (`torch.nn.Modules`) that work with the pretrained weights provided in the library. In TF2, these are `tf.keras.Model`.
- **configuration classes** which store all the parameters required to build a model, e.g., `BertConfig`. You don't always need to instantiate these your-self. In particular, if you are using a pretrained model without any modification, creating the model will automatically take care of instantiating the configuration (which is part of the model)
- **tokenizer classes** which store the vocabulary for each model and provide methods for encoding/decoding strings in a list of token embeddings indices to be fed to a model, e.g., `BertTokenizer`
- **model classes** which are PyTorch models (`torch.nn.Modules`) of the 8 models architectures currently provided in the library, e.g. `BertModel`

You don't always need to instantiate these your-self, in particular if you are using a pretrained model without any modification, creating the model will automatically take care of instantiating the configuration (which is part of the model)
- **tokenizer classes** which store the vocabulary for each model and provide methods for encoding/decoding strings in list of token embeddings indices to be fed to a model, e.g. `BertTokenizer`

- `from_pretrained()` let you instantiate a model/configuration/tokenizer from a pretrained version either provided by the library itself (currently 27 models are provided as listed [here](https://huggingface.co/transformers/pretrained_models.html)) or stored locally (or on a server) by the user,
- `save_pretrained()` let you save a model/configuration/tokenizer locally so that it can be reloaded using `from_pretrained()`.

GPT-2, as well as some other models (GPT, XLNet, Transfo-XL, CTRL), make use of a `past` or `mems` attribute which can be used to prevent re-computing the key/value pairs when using sequential decoding. It is useful when generating sequences as a big part of the attention mechanism benefits from previous computations.

model only attends to the left context (tokens on the left of the mask). Such a training is particularly interesting
for generation tasks.
Usually, the next token is predicted by sampling from the logits of the last hidden state the model produces from the input sequence.
There is currently no pipeline to do causal language modeling/generation.
Here is an example using the tokenizer and model and leveraging the :func:`~transformers.PreTrainedModel.top_k_top_p_filtering` method to sample the next token following an input sequence of tokens.

Text Generation
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
In text generation (*a.k.a* *open-ended text generation*) the goal is to create a coherent portion of text that is a continuation from the given context. As an example, is it shown how *GPT-2* can be used in pipelines to generate text. As a default all models apply *Top-K* sampling when used in pipelines as configured in their respective configurations (see `gpt-2 config <https://s3.amazonaws.com/models.huggingface.co/bert/gpt2-config.json>`_ for example).
::
from transformers import pipeline
text_generator = pipeline("text-generation")
print(text_generator("As far as I am concerned, I will", max_length=50))
Here the model generates a random text with a total maximal length of *50* tokens from context *"As far as I am concerned, I will"*.
The default arguments of ``PreTrainedModel.generate()`` can directly be overriden in the pipeline as is shown above for the argument ``max_length``.
Here is an example for text generation using XLNet and its tokenzier.
Here is an example using the tokenizer and model. leveraging the :func:`~transformers.PreTrainedModel.generate` method

GPT-2 is usually a good choice for *open-ended text generation* because it was trained on millions on webpages with a causal language modeling objective.

# Turkish ELECTRA model
We release a base ELEC**TR**A model for Turkish, that was trained on the same data as *BERTurk*.
> ELECTRA is a new method for self-supervised language representation learning. It can be used to
> pre-train transformer networks using relatively little compute. ELECTRA models are trained to
> distinguish "real" input tokens vs "fake" input tokens generated by another neural network, similar to
> the discriminator of a GAN.
More details about ELECTRA can be found in the [ICLR paper](https://openreview.net/forum?id=r1xMH1BtvB)
or in the [official ELECTRA repository](https://github.com/google-research/electra) on GitHub.
## Stats
The current version of the model is trained on a filtered and sentence
segmented version of the Turkish [OSCAR corpus](https://traces1.inria.fr/oscar/),
a recent Wikipedia dump, various [OPUS corpora](http://opus.nlpl.eu/) and a
special corpus provided by [Kemal Oflazer](http://www.andrew.cmu.edu/user/ko/).
The final training corpus has a size of 35GB and 44,04,976,662 tokens.
Thanks to Google's TensorFlow Research Cloud (TFRC) we could train a cased model
on a TPU v3-8 for 1M steps.
## Model weights

# COVID-Twitter-BERT (CT-BERT)
BERT-large-uncased model, pretrained on a corpus of messages from Twitter about COVID-19
## Overview
This model was trained on 160M tweets collected between January 12 and April 16, 2020 containing at least one of the keywords "wuhan", "ncov", "coronavirus", "covid", or "sars-cov-2". These tweets were filtered and preprocessed to reach a final sample of 22.5M tweets (containing 40.7M sentences and 633M tokens) which were used for training.
This model was evaluated based on downstream classification tasks, but it could be used for any other NLP task which can leverage contextual embeddings.
In order to achieve best results, make sure to use the same text preprocessing as we did for pretraining. This involves replacing user mentions, urls and emojis. You can find a script on our projects [GitHub repo](https://github.com/digitalepidemiologylab/covid-twitter-bert).
## Example usage
```python
tokenizer = AutoTokenizer.from_pretrained("digitalepidemiologylab/covid-twitter-bert")
model = TFAutoModel.from_pretrained("digitalepidemiologylab/covid-twitter-bert")
```

# bert-base-romanian-cased-v1
The BERT **base**, **cased** model for Romanian, trained on a 15GB corpus, version ![v1.0](https://img.shields.io/badge/v1.0-21%20Apr%202020-ff6666)
### How to use
```python
from transformers import AutoTokenizer, AutoModel
import torch
# load tokenizer and model
tokenizer = AutoTokenizer.from_pretrained("dumitrescustefan/bert-base-romanian-cased-v1")
model = AutoModel.from_pretrained("dumitrescustefan/bert-base-romanian-cased-v1")
# tokenize a sentence and run through the model
input_ids = torch.tensor(tokenizer.encode("Acesta este un test.", add_special_tokens=True)).unsqueeze(0) # Batch size 1
outputs = model(input_ids)
# get encoding
last_hidden_states = outputs[0] # The last hidden-state is the first element of the output tuple
```

## Reformer Language model on character level and trained on enwik8.
*enwik8* is a dataset based on Wikipedia and is often used to measure the model's ability to *compress* data, *e.g.* in
the scope of the *Hutter prize*: https://en.wikipedia.org/wiki/Hutter_Prize.
`reformer-enwik8` was pretrained on the first 90M chars of *enwik8* whereas the text was chunked into batches of size 65536 chars (=2^16).
The model's weights were taken from https://console.cloud.google.com/storage/browser/trax-ml/reformer/enwik8 and converted
to Hugging Face's PyTorch ReformerLM model `ReformerModelWithLMHead`.
The model is a language model that operates on characters.
Therefore, this model does not need a tokenizer. The following function can instead be used for **encoding** and **decoding**:
```python
import torch
# Encoding
def encode(list_of_strings, pad_to_max_length=True, pad_token_id=0):
max_length = max([len(string) for string in list_of_strings])
# create emtpy tensors
attention_masks = torch.zeros((len(list_of_strings), max_length), dtype=torch.long)
input_ids = torch.full((len(list_of_strings), max_length), pad_token_id, dtype=torch.long)
for idx, string in enumerate(list_of_strings):
# make sure string is in byte format
if not isinstance(string, bytes):
string = str.encode(string)
input_ids[idx, :len(string)] = torch.tensor([x + 2 for x in string])
attention_masks[idx, :len(string)] = 1
return input_ids, attention_masks
# Decoding
def decode(outputs_ids):
decoded_outputs = []
for output_ids in outputs_ids.tolist():
# transform id back to char IDs < 2 are simply transformed to ""
decoded_outputs.append("".join([chr(x - 2) if x > 1 else "" for x in output_ids]))
return decoded_outputs
```
Text can be generated as follows:
```python
from transformers import ReformerModelWithLMHead
model = ReformerModelWithLMHead.from_pretrained("google/reformer-enwik8")
encoded, attention_masks = encode(["In 1965, Brooks left IBM to found the Department of"])
decode(model.generate(encoded, do_sample=True, max_length=150))
# gives:
# In 1965, Brooks left IBM to found the Department of Journalism in 1968. IBM had jurisdiction himself in 1980, while Brooks resolved, nevertheless thro

```python
from transformers import T5Tokenizer, T5ForConditionalGeneration
tokenizer = T5Tokenizer.from_pretrained('huseinzol05/t5-base-bahasa-cased')
model = T5ForConditionalGeneration.from_pretrained('huseinzol05/t5-base-bahasa-cased')
input_ids = tokenizer.encode('soalan: siapakah perdana menteri malaysia?', return_tensors = 'pt')
outputs = model.generate(input_ids)
print(tokenizer.decode(outputs[0]))
```
Output is,
```
'Mahathir Mohamad'
```

Ankara'nın başkent ilan edilmesinin ardından (13 Ekim 1923) şehir hızla gelişmiş ve Türkiye'nin ikinci en kalabalık ili olmuştur.
Türkiye Cumhuriyeti'nin ilk yıllarında ekonomisi tarım ve hayvancılığa dayanan ilin topraklarının yarısı hâlâ tarım amaçlı
kullanılmaktadır. Ekonomik etkinlik büyük oranda ticaret ve sanayiye dayalıdır. Tarım ve hayvancılığın ağırlığı ise giderek
azalmaktadır. Ankara ve civarındaki gerek kamu sektörü gerek özel sektör yatırımları, başka illerden büyük bir nüfus göçünü
teşvik etmiştir. Cumhuriyetin kuruluşundan günümüze, nüfusu ülke nüfusunun iki katı hızda artmıştır. Nüfusun yaklaşık dörtte
üçü hizmet sektörü olarak tanımlanabilecek memuriyet, ulaşım, haberleşme ve ticaret benzeri işlerde, dörtte biri sanayide,
%2'si ise tarım alanında çalışır. Sanayi, özellikle tekstil, gıda ve inşaat sektörlerinde yoğunlaşmıştır. Günümüzde ise en çok
savunma, metal ve motor sektörlerinde yatırım yapılmaktadır. Türkiye'nin en çok sayıda üniversiteye sahip ili olan Ankara'da
ayrıca, üniversite diplomalı kişi oranı ülke ortalamasının iki katıdır. Bu eğitimli nüfus, teknoloji ağırlıklı yatırımların
gereksinim duyduğu iş gücünü oluşturur. Ankara'dan otoyollar, demir yolu ve hava yoluyla Türkiye'nin diğer şehirlerine ulaşılır.

# German Sentiment Classification with Bert
This model was trained for sentiment classification of German language texts. To achieve the best results all model inputs needs to be preprocessed with the same procedure, that was applied during the training. To simplify the usage of the model,
we provide a Python package that bundles the code need for the preprocessing and inferencing.
The model uses the Googles Bert architecture and was trained on 1.834 million German-language samples. The training data contains texts from various domains like Twitter, Facebook and movie, app and hotel reviews.
You can find more information about the dataset and the training process in the [paper](http://www.lrec-conf.org/proceedings/lrec2020/pdf/2020.lrec-1.201.pdf).
## Using the Python package
To get started install the package from [pypi](https://pypi.org/project/germansentiment/):
```bash
pip install germansentiment
```
```python
from germansentiment import SentimentModel
model = SentimentModel()
texts = [
"Mit keinem guten Ergebniss","Das ist gar nicht mal so gut",
"Total awesome!","nicht so schlecht wie erwartet",
"Der Test verlief positiv.","Sie fährt ein grünes Auto."]
result = model.predict_sentiment(texts)
print(result)
```
The code above will output following list:
```python
["negative","negative","positive","positive","neutral", "neutral"]
```
## minimal working Sample
```python
from transformers import AutoModelForSequenceClassification, AutoTokenizer
from typing import List

# ouBioBERT-Base, Uncased
Bidirectional Encoder Representations from Transformers for Biomedical Text Mining by Osaka University (ouBioBERT) is a language model based on the BERT-Base (Devlin, et al., 2019) architecture. We pre-trained ouBioBERT on PubMed abstracts from the PubMed baseline (ftp://ftp.ncbi.nlm.nih.gov/pubmed/baseline) via our method.
The details of the pre-training procedure can be found in Wada, et al. (2020).
## Evaluation
We evaluated the performance of ouBioBERT in terms of the biomedical language understanding evaluation (BLUE) benchmark (Peng, et al., 2019). The numbers are mean (standard deviation) on five different random seeds.

"Indeed, businesses might have other requirements _(languages, hardware, ...)_ for which the training framework might not be the best suited in inference scenarios. In that context, having a representation of the actual computation graph that can be shared accross various business units and logics across an organization might be a desirable component.\n",
"\n",
"Along with the serialization format, ONNX also provides a runtime library which allows efficient and hardware specific execution of the ONNX graph.

- contains `bert`: TFBertForMultipleChoice (Bert model)
The model is set in evaluation mode by default using `model.eval()` (Dropout modules are deactivated)
To train the model, you should first set it back in training mode with `model.train()`
Params:
pretrained_model_name_or_path: either:
- a string with the `shortcut name` of a pre-trained model to load from cache or download, e.g.: ``bert-base-uncased``.
- a string with the `identifier name` of a pre-trained model that was user-uploaded to our S3, e.g.: ``dbmdz/bert-base-german-cased``.
- a path to a `directory` containing model weights saved using :func:`~transformers.PreTrainedModel.save_pretrained`, e.g.: ``./my_model_directory/``.
- a path or url to a `PyTorch, TF 1.X or TF 2.0 checkpoint file` (e.g. `./tf_model/model.ckpt.index`). In the case of a PyTorch checkpoint, ``from_pt`` should be set to True and a configuration object should be provided as ``config`` argument.
from_pt: (`Optional`) Boolean
Set to True if the Checkpoint is a PyTorch checkpoint.
model_args: (`optional`) Sequence of positional arguments:
All remaning positional arguments will be passed to the underlying model's ``__init__`` method
config: (`optional`) instance of a class derived from :class:`~transformers.PretrainedConfig`:
Configuration for the model to use instead of an automatically loaded configuation. Configuration can be automatically loaded when:
- the model is a model provided by the library (loaded with the ``shortcut-name`` string of a pretrained model), or
- the model was saved using :func:`~transformers.PreTrainedModel.save_pretrained` and is reloaded by suppling the save directory.
- the model is loaded by suppling a local directory as ``pretrained_model_name_or_path`` and a configuration JSON file named `config.json` is found in the directory.
state_dict: (`optional`) dict:
an optional state dictionnary for the model to use instead of a state dictionary loaded from saved weights file.
This option can be used if you want to create a model from a pretrained configuration but load your own weights.
In this case though, you should check if using :func:`~transformers.PreTrainedModel.save_pretrained` and :func:`~transformers.PreTrainedModel.from_pretrained` is not a simpler option.
cache_dir: (`optional`) string:
Path to a directory in which a downloaded pre-trained model
configuration should be cached if the standard cache should not be used.
force_download: (`optional`) boolean, default False:
Force to (re-)download the model weights and configuration files and override the cached versions if they exists.
resume_download: (`optional`) boolean, default False:
Do not delete incompletely recieved file. Attempt to resume the download if such a file exists.
proxies: (`optional`) dict, default None:
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: (`optional`) boolean:
Set to ``True`` to also return a dictionnary containing missing keys, unexpected keys and error messages.
kwargs: (`optional`) Remaining dictionary of keyword arguments:
Can be used to update the configuration object (after it being loaded) and initiate the model. (e.g. ``output_attention=True``). Behave 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 (:func:`~transformers.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.
Examples::
model = TFAutoModelFormultipleChoice.from_pretrained('bert-base-uncased') # Download model and configuration from S3 and cache.
model = TFAutoModelFormultipleChoice.from_pretrained('./test/bert_model/') # E.g. model was saved using `save_pretrained('./test/saved_model/')`
model = TFAutoModelFormultipleChoice.from_pretrained('bert-base-uncased', output_attention=True) # Update configuration during loading
assert model.config.output_attention == True
# Loading from a TF checkpoint file instead of a PyTorch model (slower)
