class PretrainedConfig:
|
|
r"""
|
|
Base class for all configuration classes. Handles a few parameters common to all models' configurations as well as
|
|
methods for loading/downloading/saving configurations.
|
|
|
|
<Tip>
|
|
|
|
A configuration file can be loaded and saved to disk. Loading the configuration file and using this file to
|
|
initialize a model does **not** load the model weights. It only affects the model's configuration.
|
|
|
|
</Tip>
|
|
|
|
Class attributes (overridden by derived classes):
|
|
|
|
- **model_type** (`str`) -- An identifier for the model type, serialized into the JSON file, and used to recreate
|
|
the correct object in [`~paddlenlp.AutoConfig`].
|
|
- **is_composition** (`bool`) -- Whether the config class is composed of multiple sub-configs. In this case the
|
|
config has to be initialized from two or more configs of type [`~paddlenlp.PretrainedConfig`] like:
|
|
[`~paddlenlp.EncoderDecoderConfig`] or [`~RagConfig`].
|
|
- **keys_to_ignore_at_inference** (`List[str]`) -- A list of keys to ignore by default when looking at dictionary
|
|
outputs of the model during inference.
|
|
- **attribute_map** (`Dict[str, str]`) -- A dict that maps model specific attribute names to the standardized
|
|
naming of attributes.
|
|
|
|
Common attributes (present in all subclasses):
|
|
|
|
- **vocab_size** (`int`) -- The number of tokens in the vocabulary, which is also the first dimension of the
|
|
embeddings matrix (this attribute may be missing for models that don't have a text modality like ViT).
|
|
- **hidden_size** (`int`) -- The hidden size of the model.
|
|
- **num_attention_heads** (`int`) -- The number of attention heads used in the multi-head attention layers of the
|
|
model.
|
|
- **num_hidden_layers** (`int`) -- The number of blocks in the model.
|
|
|
|
Arg:
|
|
name_or_path (`str`, *optional*, defaults to `""`):
|
|
Store the string that was passed to [`PreTrainedModel.from_pretrained`] or
|
|
[`PreTrainedModel.from_pretrained`] as `pretrained_model_name_or_path` if the configuration was created
|
|
with such a method.
|
|
output_hidden_states (`bool`, *optional*, defaults to `False`):
|
|
Whether or not the model should return all hidden-states.
|
|
output_attentions (`bool`, *optional*, defaults to `False`):
|
|
Whether or not the model should returns all attentions.
|
|
return_dict (`bool`, *optional*, defaults to `True`):
|
|
Whether or not the model should return a [`~paddlenlp.transformers.model_outputs.ModelOutput`] instead of a plain tuple.
|
|
is_encoder_decoder (`bool`, *optional*, defaults to `False`):
|
|
Whether the model is used as an encoder/decoder or not.
|
|
is_decoder (`bool`, *optional*, defaults to `False`):
|
|
Whether the model is used as decoder or not (in which case it's used as an encoder).
|
|
cross_attention_hidden_size** (`bool`, *optional*):
|
|
The hidden size of the cross-attention layer in case the model is used as a decoder in an encoder-decoder
|
|
setting and the cross-attention hidden dimension differs from `self.config.hidden_size`.
|
|
add_cross_attention (`bool`, *optional*, defaults to `False`):
|
|
Whether cross-attention layers should be added to the model. Note, this option is only relevant for models
|
|
that can be used as decoder models within the [`EncoderDecoderModel`] class, which consists of all models
|
|
in `AUTO_MODELS_FOR_CAUSAL_LM`.
|
|
tie_encoder_decoder (`bool`, *optional*, defaults to `False`):
|
|
Whether all encoder weights should be tied to their equivalent decoder weights. This requires the encoder
|
|
and decoder model to have the exact same parameter names.
|
|
prune_heads (`Dict[int, List[int]]`, *optional*, defaults to `{}`):
|
|
Pruned heads of the model. The keys are the selected layer indices and the associated values, the list of
|
|
heads to prune in said layer.
|
|
|
|
For instance `{1: [0, 2], 2: [2, 3]}` will prune heads 0 and 2 on layer 1 and heads 2 and 3 on layer 2.
|
|
chunk_size_feed_forward (`int`, *optional*, defaults to `0`):
|
|
The chunk size of all feed forward layers in the residual attention blocks. A chunk size of `0` means that
|
|
the feed forward layer is not chunked. A chunk size of n means that the feed forward layer processes `n` <
|
|
sequence_length embeddings at a time. For more information on feed forward chunking, see [How does Feed
|
|
Forward Chunking work?](../glossary.html#feed-forward-chunking).
|
|
|
|

min_length (`int`, *optional*, defaults to 10):
|
|
Minimum length that will be used by default in the `generate` method of the model.
|

|
|
when at least `num_beams` sentences are finished per batch or not.
|
|
num_beams (`int`, *optional*, defaults to 1):
|
|
Number of beams for beam search that will be used by default in the `generate` method of the model. 1 means
|
|
no beam search.

|
num_beam_groups (`int`, *optional*, defaults to 1):
|
|
Number of groups to divide `num_beams` into in order to ensure diversity among different groups of beams

|
|
diversity_penalty (`float`, *optional*, defaults to 0.0):
|
|
Value to control diversity for group beam search. that will be used by default in the `generate` method of
|
|
the model. 0 means no diversity penalty. The higher the penalty, the more diverse are the outputs.
|
|
temperature (`float`, *optional*, defaults to 1):
|
|

|
|
of the model. Must be strictly positive.

|
top_p (`float`, *optional*, defaults to 1):
|
|
Value that will be used by default in the `generate` method of the model for `top_p`. 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 (`float`, *optional*, defaults to 1):
|
|
Parameter for repetition penalty that will be used by default in the `generate` method of the model. 1.0
|
|
means no penalty.
|
|

|
|
Exponential penalty to the length that will be used by default in the `generate` method of the model.
|
|
no_repeat_ngram_size (`int`, *optional*, defaults to 0) -- Value that will be used by default in the

forced_bos_token_id (`int`, *optional*):
|
|
The id of the token to force as the first generated token after the `decoder_start_token_id`. Useful for
|
|
multilingual models like [mBART](../model_doc/mbart) where the first generated token needs to be the target
|
|
language token.
|
|
forced_eos_token_id (`int`, *optional*):
|
|
The id of the token to force as the last generated token when `max_length` is reached.
|
|
remove_invalid_values (`bool`, *optional*):
|
|
Whether to remove possible _nan_ and _inf_ outputs of the model to prevent the generation method to crash.
|
|
Note that using `remove_invalid_values` can slow down generation.
|
|
|
|
> Parameters for fine-tuning tasks
|
|
|
|
architectures (`List[str]`, *optional*):
|
|
Model architectures that can be used with the model pretrained weights.
|
|
finetuning_task (`str`, *optional*):
|
|
Name of the task used to fine-tune the model. This can be used when converting from an original checkpoint.
|
|
id2label (`Dict[int, str]`, *optional*):
|
|
A map from index (for instance prediction index, or target index) to label.
|
|
label2id (`Dict[str, int]`, *optional*): A map from label to index for the model.
|
|
num_labels (`int`, *optional*):
|
|
Number of labels to use in the last layer added to the model, typically for a classification task.
|
|
task_specific_params (`Dict[str, Any]`, *optional*):
|
|
Additional keyword arguments to store for the current task.
|
|
problem_type (`str`, *optional*):
|
|
Problem type for `XxxForSequenceClassification` models. Can be one of `"regression"`,
|
|
`"single_label_classification"` or `"multi_label_classification"`.
|
|
|
|
> Parameters linked to the tokenizer
|
|
|
|
tokenizer_class (`str`, *optional*):
|
|
The name of the associated tokenizer class to use (if none is set, will use the tokenizer associated to the
|
|
model by default).
|
|
prefix (`str`, *optional*):
|
|
A specific prompt that should be added at the beginning of each text before calling the model.
|
|
bos_token_id (`int`, *optional*): The id of the _beginning-of-stream_ token.
|
|
pad_token_id (`int`, *optional*): The id of the _padding_ token.
|
|
eos_token_id (`int`, *optional*): The id of the _end-of-stream_ token.
|
|
decoder_start_token_id (`int`, *optional*):
|
|
If an encoder-decoder model starts decoding with a different token than _bos_, the id of that token.
|
|
sep_token_id (`int`, *optional*): The id of the _separation_ token.
|
|
|
|
tie_word_embeddings (`bool`, *optional*, defaults to `True`):
|
|
Whether the model's input and output word embeddings should be tied. Note that this is only relevant if the
|
|
model has a output word embedding layer.
|
|
dtype (`str`, *optional*):
|
|
The `dtype` of the weights. This attribute can be used to initialize the model to a non-default `dtype`
|
|
(which is normally `float32`) and thus allow for optimal storage allocation. For example, if the saved
|
|
model is `float16`, ideally we want to load it back using the minimal amount of memory needed to load
|
|
`float16` weights. Since the config object is stored in plain text, this attribute contains just the
|
|
floating type string without the `paddle.` prefix. For example, for `paddle.float16` ``dtype` is the
|
|
`"float16"` string.
|
|
|
|
This attribute is currently not being used during model loading time, but this may change in the future
|
|
versions. But we can already start preparing for the future by saving the dtype with save_pretrained.
