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 32000) – Vocabulary size of the Llama model. Defines the number of different tokens that can be represented by the inputs_ids passed to the forward method.

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

  • intermediate_size (int, optional, defaults to 11008) – Dimensionality of the “intermediate” (i.e., feed-forward) layer in the Transformer encoder.

  • num_hidden_layers (int, optional, defaults to 32) – Number of hidden layers in the Transformer encoder.

  • num_attention_heads (int, optional, defaults to 32) – Number of attention heads for each attention layer in the Transformer encoder.

  • number_rep_kv (int, optional, defaults to 1) – Number of repetitions for the key and value vectors.

  • num_key_value_heads (int, optional) – Number of key and value heads for each attention layer in the Transformer encoder. Will default to number_rep_kv * num_attention_heads if not set.

  • max_position_embeddings (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).

  • head_dim (int, optional) – head_dim for attention qkv.

  • rms_norm_eps (float, optional, defaults to 1e-6) – The epsilon used by the rms 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 0) – The id of the beginning-of-sequence token.

  • eos_token_id (int, optional, defaults to 1) – The id of the end-of-sequence token.

  • 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.

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

  • rope_theta (float, optional, defaults to 10000.0) – The theta value to use for rotary position embeddings.

  • attention_bias (bool, optional, defaults to False) – Whether to use attention bias.

  • 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 “nothing_saveable”) – The gradient checkpointing configuration.

  • fcm_min_ratio (float, optional, defaults to -1) – The minimum ratio for Flash Attention.

  • fcm_max_ratio (float, optional, defaults to -1) – The maximum ratio for Flash Attention.

  • rope_scaling (tp.Dict[str, tp.Union[str, float]], optional) – The configuration for rope scaling.

  • scan_mlp_chunk_size (int, optional, defaults to 1024) – The chunk size to use when scanning the MLP.

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

  • hidden_act (str, optional, defaults to “silu”) – The hidden activation function to use.

  • pretraining_tp (int, optional, defaults to 1) – The tensor parallelism degree used during pretraining.

  • mlp_bias (bool, optional, defaults to False) – Whether to use bias in the MLP.

  • scan_layers (bool, optional, defaults to False) – Whether to use the scan implementation for the layers.
