| class BioGptConfig(PretrainedConfig): | |
| r""" | |
| This is the configuration class to store the configuration of a [`BioGptModel`]. It is used to instantiate an | |
| BioGPT 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 BioGPT | |
| [microsoft/biogpt](https://huggingface.co/microsoft/biogpt) architecture. | |
| Configuration objects inherit from [`PretrainedConfig`] and can be used to control the model outputs. Read the | |
| documentation from [`PretrainedConfig`] for more information. | |
| Args: | |
| vocab_size (`int`, *optional*, defaults to 42384): | |
| Vocabulary size of the BioGPT model. Defines the number of different tokens that can be represented by the | |
| `inputs_ids` passed when calling [`BioGptModel`]. | |
| hidden_size (`int`, *optional*, defaults to 1024): | |
| Dimension of the encoder layers and the pooler layer. | |
| num_hidden_layers (`int`, *optional*, defaults to 24): | |
| Number of hidden layers in the Transformer encoder. | |
| num_attention_heads (`int`, *optional*, defaults to 16): | |
| Number of attention heads for each attention layer in the Transformer encoder. | |
| intermediate_size (`int`, *optional*, defaults to 4096): | |
| Dimension of the "intermediate" (i.e., feed-forward) layer in the Transformer encoder. | |
| hidden_act (`str` or `function`, *optional*, defaults to `"gelu"`): | |
| The non-linear activation function (function or string) in the encoder and pooler. If string, `"gelu"`, | |
| `"relu"`, `"selu"` and `"gelu_new"` are supported. | |
| hidden_dropout_prob (`float`, *optional*, defaults to 0.1): | |
| The dropout probabilitiy for all fully connected layers in the embeddings, encoder, and pooler. | |
| attention_probs_dropout_prob (`float`, *optional*, defaults to 0.1): | |
| The dropout ratio for the attention probabilities. | |
| max_position_embeddings (`int`, *optional*, defaults to 1024): | |
| The maximum sequence length that this model might ever be used with. Typically set this to something large | |
| just in case (e.g., 512 or 1024 or 2048). | |
| initializer_range (`float`, *optional*, defaults to 0.02): | |
| The standard deviation of the truncated_normal_initializer for initializing all weight matrices. | |
| layer_norm_eps (`float`, *optional*, defaults to 1e-12): | |
| The epsilon used by the layer normalization layers. | |
| scale_embedding (`bool`, *optional*, defaults to `True`): | |
| Scale embeddings by diving by sqrt(d_model). | |
| use_cache (`bool`, *optional*, defaults to `True`): | |
| Whether or not the model should return the last key/values attentions (not used by all models). Only | |
| relevant if `config.is_decoder=True`. | |
| layerdrop (`float`, *optional*, defaults to 0.0): | |
| Please refer to the paper about LayerDrop: https://arxiv.org/abs/1909.11556 for further details | |
| activation_dropout (`float`, *optional*, defaults to 0.0): | |
| The dropout ratio for activations inside the fully connected layer. | |
| pad_token_id (`int`, *optional*, defaults to 1): | |
| Padding token id. | |
| bos_token_id (`int`, *optional*, defaults to 0): | |
| Beginning of stream token id. | |
| eos_token_id (`int`, *optional*, defaults to 2): | |
| End of stream token id. | |
| Example: | |
| ```python | |
| >>> from transformers import BioGptModel, BioGptConfig | |
| >>> # Initializing a BioGPT microsoft/biogpt style configuration | |
| >>> configuration = BioGptConfig() | |
| >>> # Initializing a model from the microsoft/biogpt style configuration | |
| >>> model = BioGptModel(configuration) | |
| >>> # Accessing the model configuration | |
| >>> configuration = model.config | |
