개요

일본어를 위한 자동회귀 언어 모델인 GPT-NeoX-Japanese를 소개합니다. 이 모델은 https://github.com/EleutherAI/gpt-neox에서 학습되었습니다. 일본어는 많은 어휘와 히라가나, 가타카나, 한자의 조합으로 이루어진 독특한 언어입니다. 이러한 일본어의 독특한 구조를 해결하기 위해 특수 서브워드 토크나이저를 사용했습니다. 이 유용한 토크나이저를 오픈소스로 제공해 준 tanreinama에게 매우 감사드립니다.

이 모델은 Google의 PaLM 연구 권장 사항을 따르며, 트랜스포머 블록에서 편향 파라미터를 제거하여 모델 성능을 향상시켰습니다. 자세한 내용은 이 기사를 참조하세요.

모델 개발은 ABEJA, Inc.의 신야 오타니, 타카요시 마카베, 안주 아로라, 쿄 하토리에 의해 주도되었습니다. 이 모델 개발 활동에 대한 자세한 내용은 여기를 참조하세요.

- Example —

This is the configuration class to store the configuration of a `GPTNeoXModelJapanese`. It is used to instantiate a GPTNeoX 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 GPTNeoXJapanese abeja/gpt-neox-japanese-2.7b architecture.

Configuration objects inherit from PretrainedConfig and can be used to control the model outputs. Read the documentation from PretrainedConfig for more information. Default configs is set as 2.7B model

    >>> from transformers import GPTNeoXJapaneseConfig, GPTNeoXJapaneseModel

    >>> # Initializing a GPTNeoXJapanese gpt-neox-japanese-2.7b style configuration
    >>> configuration = GPTNeoXJapaneseConfig()

    >>> # Initializing a model (with random weights) from the gpt-neox-japanese-2.7b style configuration
    >>> model = GPTNeoXJapaneseModel(configuration)

    >>> # Accessing the model configuration
    >>> configuration = model.config

( vocab_file emoji_file unk_token = '<|endoftext|>' pad_token = '<|endoftext|>' bos_token = '<|startoftext|>' eos_token = '<|endoftext|>' do_clean_text = False **kwargs )

Parameters

- vocab_file (`str`) — File containing the vocabulary.
- emoji_file (`str`) — File containing the emoji.
- unk_token (`str`, optional, defaults to `"<|endoftext|>"`) — 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 `"<|endoftext|>"`) — The token used for padding
- bos_token (`str`, optional, defaults to `"<|startoftext|>"`) — The beginning of sequence token.

- do_clean_text (`bool`, optional, defaults to `False`) — Whether or not to clean text for URL, EMAIL, TEL, Japanese DATE and Japanese PRICE.

This tokenizer inherits from `PreTrainedTokenizer` and is based on Japanese special Sub-Word-Encoding that is used in this repository (https://github.com/tanreinama/Japanese-BPEEncoder_V2). Check the repository for details. Japanese has a relatively large vocabulary and there is no separation between words. Furthermore, the language is a combination of hiragana, katakana, and kanji, and variants such as “1” and “①” are often used. In order to cope with these, this tokenizer has the following features

- Subword-by-subword segmentation, which is intermediate between byte strings and morphological analysis.
- BPEs are created for each Kanji, Hiragana, and Katakana character, and there are no BPEs that cross character types, such as Kanji + Hiragana or Hiragana + Katakana.
- All-byte encoding that does not require <unk>.
- Independent of UTF codes such as 2-byte and 3-byte characters
- Conversion of heterographs to the same token_id
- Emoji and Emoticon are grouped into 12 types as special tags.

Example:

    >>> from transformers import GPTNeoXJapaneseTokenizer

    >>> tokenizer = GPTNeoXJapaneseTokenizer.from_pretrained("abeja/gpt-neox-japanese-2.7b")
    >>> # You can confirm both 慶応 and 慶應 are encoded to 17749
    >>> tokenizer("吾輩は猫である🐯。実は慶応(慶應)大学出身")["input_ids"]
    [30014, 26883, 26638, 27228, 25, 26650, 31732, 31679, 27809, 26638, 17749, 31592, 17749, 31593, 321, 1281]

    >>> # Both 慶応 and 慶應 are decoded to 慶応
    >>> tokenizer.decode(tokenizer("吾輩は猫である🐯。実は慶応(慶應)大学出身")["input_ids"])
    '吾輩は猫である🐯。実は慶応(慶応)大学出身'

class transformers.GPTNeoXJapaneseModel

( config )

Parameters

- config (GPTNeoXJapaneseModel) — 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 from_pretrained() method to load the model weights.

The bare Gpt Neox Japanese Model outputting raw hidden-states without any specific head on top.

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 subclass. Use it as a regular PyTorch Module and refer to the PyTorch documentation for all matter related to general usage and behavior.

transformers.modeling_outputs.BaseModelOutputWithPast or `tuple(torch.FloatTensor)`

Parameters

- input_ids (`torch.LongTensor` of shape `(batch_size, sequence_length)`, optional) — Indices of input sequence tokens in the vocabulary. Padding will be ignored by default.

  Indices can be obtained using AutoTokenizer. See PreTrainedTokenizer.encode() and PreTrainedTokenizer.call() for details.

  What are input IDs?

- 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?

- 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.n_positions - 1]`.

  What are 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.
- past_key_values (`Union[~cache_utils.Cache, Tuple[Tuple[torch.FloatTensor]], NoneType]`) — 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 instance, see our kv cache guide;
  - 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)`.

- 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 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.

Returns

transformers.modeling_outputs.BaseModelOutputWithPast or `tuple(torch.FloatTensor)`

A transformers.modeling_outputs.BaseModelOutputWithPast or a tuple of `torch.FloatTensor` (if `return_dict=False` is passed or when `config.return_dict=False`) comprising various elements depending on the configuration (GPTNeoXJapaneseConfig) and inputs.

- last_hidden_state (`torch.FloatTensor` of shape `(batch_size, sequence_length, hidden_size)`) — Sequence of hidden-states at the output of the last layer of the model.

  If `past_key_values` is used only the last hidden-state of the sequences of shape `(batch_size, 1, hidden_size)` is output.

- past_key_values (`Cache`, optional, returned when `use_cache=True` is passed or when `config.use_cache=True`) — It is a Cache instance. For more details, see our kv cache guide.

  Contains pre-computed hidden-states (key and values in the self-attention blocks and optionally if `config.is_encoder_decoder=True` in the cross-attention blocks) that can be used (see `past_key_values` input) to speed up sequential decoding.

- hidden_states (`tuple(torch.FloatTensor)`, optional, returned when `output_hidden_states=True` is passed or when `config.output_hidden_states=True`) — Tuple of `torch.FloatTensor` (one for the output of the embeddings, if the model has an embedding layer, + one for the output of each layer) of shape `(batch_size, sequence_length, hidden_size)`.

  Hidden-states of the model at the output of each layer plus the optional initial embedding outputs.

- attentions (`tuple(torch.FloatTensor)`, optional, returned when `output_attentions=True` is passed or when `config.output_attentions=True`) — Tuple of `torch.FloatTensor` (one for each layer) of shape `(batch_size, num_heads, sequence_length, sequence_length)`.

  Attentions weights after the attention softmax, used to compute the weighted average in the self-attention heads.

The GPTNeoXJapaneseModel forward method, overrides the `__call__` special method.

Although the recipe for forward pass needs to be defined within this function, one should call the `Module` instance afterwards instead of this since the former takes care of running the pre and post processing steps while the latter silently ignores them.

Example:

    >>> from transformers import AutoTokenizer, GPTNeoXJapaneseModel
    >>> import torch

    >>> tokenizer = AutoTokenizer.from_pretrained("abeja/gpt-neox-japanese-2.7b")
    >>> model = GPTNeoXJapaneseModel.from_pretrained("abeja/gpt-neox-japanese-2.7b")

    >>> inputs = tokenizer("日本語のGPT-neoxがHugging Faceで使えます😀", return_tensors="pt")
    >>> outputs = model(**inputs)

    >>> last_hidden_states = outputs.last_hidden_state
