Generates sequences for models with a language modeling head. The method currently supports greedy decoding,
beam-search decoding, sampling with temperature, sampling with top-k or nucleus sampling.
Adapted in part from `Facebook's XLM beam search code
<https://github.com/facebookresearch/XLM/blob/9e6f6814d17be4fe5b15f2e6c43eb2b2d76daeb4/src/model/transformer.py#L529>`__.
Apart from :obj:`input_ids` and :obj:`attention_mask`, all the arguments below will default to the value of the
attribute of the same name inside the :class:`~transformers.PretrainedConfig` of the model. The default values
indicated are the default values of those config.
Most of these parameters are explained in more detail in `this blog post
<https://huggingface.co/blog/how-to-generate>`__.
Parameters:
input_ids (:obj:`torch.LongTensor` of shape :obj:`(batch_size, sequence_length)`, `optional`):
The sequence used as a prompt for the generation. If :obj:`None` the method initializes
it as an empty :obj:`torch.LongTensor` of shape :obj:`(1,)`.
decoder_input_ids (:obj:`torch.LongTensor` of shape :obj:`(batch_size, sequence_length)`, `optional`):
initial input_ids for the decoder of encoder-decoder type models. If :obj:`None` then only
decoder_start_token_id is passed as the first token to the decoder.
max_length (:obj:`int`, `optional`, defaults to 20):
The maximum length of the sequence to be generated.
min_length (:obj:`int`, `optional`, defaults to 10):
The minimum length of the sequence to be generated.
do_sample (:obj:`bool`, `optional`, defaults to :obj:`False`):
Whether or not to use sampling ; use greedy decoding otherwise.
early_stopping (:obj:`bool`, `optional`, defaults to :obj:`False`):
Whether to stop the beam search when at least ``num_beams`` sentences are finished per batch or not.
num_beams (:obj:`int`, `optional`, defaults to 1):
Number of beams for beam search. 1 means no beam search.
temperature (:obj:`float`, `optional`, defaults tp 1.0):
The value used to module the next token probabilities.
top_k (:obj:`int`, `optional`, defaults to 50):
The number of highest probability vocabulary tokens to keep for top-k-filtering.
top_p (:obj:`float`, `optional`, defaults to 1.0):
If set to float < 1, only the most probable tokens with probabilities that add up to ``top_p`` or
higher are kept for generation.
repetition_penalty (:obj:`float`, `optional`, defaults to 1.0):
The parameter for repetition penalty. 1.0 means no penalty. See `this paper
<https://arxiv.org/pdf/1909.05858.pdf>`__ for more details.
pad_token_id (:obj:`int`, `optional`):
The id of the `padding` token.
bos_token_id (:obj:`int`, `optional`):
The id of the `beginning-of-sequence` token.
eos_token_id (:obj:`int`, `optional`):
The id of the `end-of-sequence` token.
length_penalty (:obj:`float`, `optional`, defaults to 1.0):
Exponential penalty to the length. 1.0 means no penalty.
Set to values < 1.0 in order to encourage the model to generate shorter sequences, to a value > 1.0 in
order to encourage the model to produce longer sequences.
no_repeat_ngram_size (:obj:`int`, `optional`, defaults to 0):
If set to int > 0, all ngrams of that size can only occur once.
bad_words_ids(:obj:`List[int]`, `optional`):
List of token ids that are not allowed to be generated. In order to get the tokens of the words that
should not appear in the generated text, use :obj:`tokenizer.encode(bad_word, add_prefix_space=True)`.
num_return_sequences(:obj:`int`, `optional`, defaults to 1):
The number of independently computed returned sequences for each element in the batch.
attention_mask (:obj:`torch.LongTensor` of shape :obj:`(batch_size, sequence_length)`, `optional`):
Mask to avoid performing attention on padding token indices. Mask values are in ``[0, 1]``, 1 for
tokens that are not masked, and 0 for masked tokens.
If not provided, will default to a tensor the same shape as :obj:`input_ids` that masks the pad token.
`What are attention masks? <../glossary.html#attention-mask>`__
decoder_start_token_id (:obj:`int`, `optional`):
If an encoder-decoder model starts decoding with a different token than `bos`, the id of that token.
use_cache: (:obj:`bool`, `optional`, defaults to :obj:`True`):
Whether or not the model should use the past last key/values attentions (if applicable to the model) to
speed up decoding.
model_kwargs:
Additional model specific kwargs will be forwarded to the :obj:`forward` function of the model.
Return:
:obj:`torch.LongTensor` of shape :obj:`(batch_size * num_return_sequences, sequence_length)`:
The generated sequences. The second dimension (sequence_length) is either equal to :obj:`max_length` or
shorter if all batches finished early due to the :obj:`eos_token_id`.
