+ Most generation-controlling parameters are set in `generation_config` which, if not passed, will be set to the
+ model's default generation configuration. You can override any `generation_config` by passing the corresponding
+ parameters to generate(), e.g. `.generate(inputs, num_beams=4, do_sample=True)`.
+
+ For an overview of generation strategies and code examples, check out the [following
+ guide](./generation_strategies).
+
+
+
+ Parameters:
+ inputs (`torch.Tensor` of varying shape depending on the modality, *optional*):
+ The sequence used as a prompt for the generation or as model inputs to the encoder. If `None` the
+ method initializes it with `bos_token_id` and a batch size of 1. For decoder-only models `inputs`
+ should of in the format of `input_ids`. For encoder-decoder models *inputs* can represent any of
+ `input_ids`, `input_values`, `input_features`, or `pixel_values`.
+ generation_config (`~generation.GenerationConfig`, *optional*):
+ The generation configuration to be used as base parametrization for the generation call. `**kwargs`
+ passed to generate matching the attributes of `generation_config` will override them. If
+ `generation_config` is not provided, the default will be used, which had the following loading
+ priority: 1) from the `generation_config.json` model file, if it exists; 2) from the model
+ configuration. Please note that unspecified parameters will inherit [`~generation.GenerationConfig`]'s
+ default values, whose documentation should be checked to parameterize generation.
+ logits_processor (`LogitsProcessorList`, *optional*):
+ Custom logits processors that complement the default logits processors built from arguments and
+ generation config. If a logit processor is passed that is already created with the arguments or a
+ generation config an error is thrown. This feature is intended for advanced users.
+ stopping_criteria (`StoppingCriteriaList`, *optional*):
+ Custom stopping criteria that complement the default stopping criteria built from arguments and a
+ generation config. If a stopping criteria is passed that is already created with the arguments or a
+ generation config an error is thrown. This feature is intended for advanced users.
+ prefix_allowed_tokens_fn (`Callable[[int, torch.Tensor], List[int]]`, *optional*):
+ If provided, this function constraints the beam search to allowed tokens only at each step. If not
+ provided no constraint is applied. This function takes 2 arguments: the batch ID `batch_id` and
+ `input_ids`. It has to return a list with the allowed tokens for the next generation step conditioned
+ on the batch ID `batch_id` and the previously generated tokens `inputs_ids`. This argument is useful
+ for constrained generation conditioned on the prefix, as described in [Autoregressive Entity
+ Retrieval](https://arxiv.org/abs/2010.00904).
+ synced_gpus (`bool`, *optional*, defaults to `False`):
+ Whether to continue running the while loop until max_length (needed for ZeRO stage 3)
+ kwargs:
+ Ad hoc parametrization of `generate_config` and/or additional model-specific kwargs that will be
+ forwarded to the `forward` function of the model. If the model is an encoder-decoder model, encoder
+ specific kwargs should not be prefixed and decoder specific kwargs should be prefixed with *decoder_*.
+
+ Return:
+ [`~utils.ModelOutput`] or `torch.LongTensor`: A [`~utils.ModelOutput`] (if `return_dict_in_generate=True`
+ or when `config.return_dict_in_generate=True`) or a `torch.FloatTensor`.
+
+ If the model is *not* an encoder-decoder model (`model.config.is_encoder_decoder=False`), the possible
+ [`~utils.ModelOutput`] types are:
+
+ - [`~generation.GreedySearchDecoderOnlyOutput`],
+ - [`~generation.SampleDecoderOnlyOutput`],
+ - [`~generation.BeamSearchDecoderOnlyOutput`],
+ - [`~generation.BeamSampleDecoderOnlyOutput`]
+
+ If the model is an encoder-decoder model (`model.config.is_encoder_decoder=True`), the possible
+ [`~utils.ModelOutput`] types are:
+
+ - [`~generation.GreedySearchEncoderDecoderOutput`],
+ - [`~generation.SampleEncoderDecoderOutput`],
+ - [`~generation.BeamSearchEncoderDecoderOutput`],
+ - [`~generation.BeamSampleEncoderDecoderOutput`]

+ Generates sequences of token ids for models with a language modeling head using **multinomial sampling** and
+ can be used for text-decoder, text-to-text, speech-to-text, and vision-to-text models.
+
+
+
+ In most cases, you do not need to call [`~generation.GenerationMixin.sample`] directly. Use generate() instead.
+ For an overview of generation strategies and code examples, check the [following
+ guide](./generation_strategies).
+
+
+
+ Parameters:
+ input_ids (`torch.LongTensor` of shape `(batch_size, sequence_length)`):
+ The sequence used as a prompt for the generation.
+ logits_processor (`LogitsProcessorList`, *optional*):
+ An instance of [`LogitsProcessorList`]. List of instances of class derived from [`LogitsProcessor`]
+ used to modify the prediction scores of the language modeling head applied at each generation step.
+ stopping_criteria (`StoppingCriteriaList`, *optional*):
+ An instance of [`StoppingCriteriaList`]. List of instances of class derived from [`StoppingCriteria`]
+ used to tell if the generation loop should stop.
+ logits_warper (`LogitsProcessorList`, *optional*):
+ An instance of [`LogitsProcessorList`]. List of instances of class derived from [`LogitsWarper`] used
+ to warp the prediction score distribution of the language modeling head applied before multinomial
+ sampling at each generation step.
+ max_length (`int`, *optional*, defaults to 20):
+ **DEPRECATED**. Use `logits_processor` or `stopping_criteria` directly to cap the number of generated
+ tokens. The maximum length of the sequence to be generated.
+ pad_token_id (`int`, *optional*):
+ The id of the *padding* token.
+ eos_token_id (`int`, *optional*):
+ The id of the *end-of-sequence* token.
+ output_attentions (`bool`, *optional*, defaults to `False`):
+ Whether or not to return the attentions tensors of all attention layers. See `attentions` under
+ returned tensors for more details.
+ output_hidden_states (`bool`, *optional*, defaults to `False`):
+ Whether or not to return the hidden states of all layers. See `hidden_states` under returned tensors
+ for more details.
+ output_scores (`bool`, *optional*, defaults to `False`):
+ Whether or not to return the prediction scores. See `scores` under returned tensors for more details.
+ return_dict_in_generate (`bool`, *optional*, defaults to `False`):
+ Whether or not to return a [`~utils.ModelOutput`] instead of a plain tuple.
+ synced_gpus (`bool`, *optional*, defaults to `False`):
+ Whether to continue running the while loop until max_length (needed for ZeRO stage 3)
+ model_kwargs:
+ Additional model specific kwargs will be forwarded to the `forward` function of the model. If model is
+ an encoder-decoder model the kwargs should include `encoder_outputs`.
+
+ Return:
+ [`~generation.SampleDecoderOnlyOutput`], [`~generation.SampleEncoderDecoderOutput`] or `torch.LongTensor`:
+ A `torch.LongTensor` containing the generated tokens (default behaviour) or a
+ [`~generation.SampleDecoderOnlyOutput`] if `model.config.is_encoder_decoder=False` and
+ `return_dict_in_generate=True` or a [`~generation.SampleEncoderDecoderOutput`] if
+ `model.config.is_encoder_decoder=True`.
