Bases: EasyDeLBaseConfig

Configuration objects inherit from [EasyDeLBaseConfig] and can be used to control the model outputs. Read the documentation from [EasyDeLBaseConfig] for more information.

Parameters

  • vocab_size (int, optional, defaults to 50400) – Vocabulary size of the GPT-J model. Defines the number of different tokens that can be represented by the inputs_ids passed to the forward method.

  • n_positions (int, optional, defaults to 2048) – The maximum sequence length that this model might ever be used with. Typically set this to something large just in case (e.g., 2048 or 4096).

  • n_embd (int, optional, defaults to 4096) – Dimensionality of the encoder layers and the pooler layer.

  • n_layer (int, optional, defaults to 28) – Number of hidden layers in the Transformer encoder.

  • n_head (int, optional, defaults to 16) – Number of attention heads for each attention layer in the Transformer encoder.

  • rotary_dim (int, optional, defaults to 64) – The dimension of the rotary position embedding.

  • n_inner (int, optional) – Dimensionality of the inner feed-forward layers.

  • activation_function (str, optional, defaults to “gelu_new”) – The non-linear activation function (function or string) to use in the encoder and pooler. If string, “gelu”, “relu”, “swish” and “gelu_new” are supported.

  • resid_pdrop (float, optional, defaults to 0.0) – The dropout probability for all fully connected layers in the embeddings, encoder, and pooler.

  • embd_pdrop (float, optional, defaults to 0.0) – The dropout ratio for the embeddings.

  • attn_pdrop (float, optional, defaults to 0.0) – The dropout ratio for the attention probabilities.

  • layer_norm_epsilon (float, optional, defaults to 1e-5) – The epsilon to use in the layer normalization layers.

  • initializer_range (float, optional, defaults to 0.02) – The standard deviation of the truncated_normal_initializer for initializing all weight matrices.

  • 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.

  • bos_token_id (int, optional, defaults to 50256) – The id of the beginning-of-sequence token.

  • eos_token_id (int, optional, defaults to 50256) – The id of the end-of-sequence token.

  • tie_word_embeddings (bool, optional, defaults to False) – Whether to tie the weights of the input embeddings and the output embeddings.

  • gradient_checkpointing (str, optional, defaults to “”) – The gradient checkpointing configuration.

  • bits (int, optional) – The number of bits to quantize the model to.
