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 50304) – Vocabulary size of the StableLM model. Defines the number of different tokens that can be represented by the inputs_ids passed when calling [~easydel.modules.StableLmModel].

  • hidden_size (int, optional, defaults to 2560) – Dimensionality of the encoder layers and the pooler layer.

  • intermediate_size (int, optional, defaults to 6912) – Dimensionality of the “intermediate” (often named 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.

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

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

  • max_position_embeddings (int, optional, defaults to 4096) – The maximum sequence length that this model might ever be used with.

  • 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-5) – The epsilon used by the layer normalization layers.

  • use_cache (bool, optional, defaults to True) – Whether or not the model should return the last key/values attentions (not used by all models).

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

  • rope_theta (int, optional, defaults to 10000) – The theta value for the rotary position embeddings.

  • rope_scaling (str, optional) – The scaling to use for the rotary position embeddings.

  • qk_layernorm (bool, optional, defaults to False) – Whether to use layer normalization on the queries and keys in the attention layer.

  • use_parallel_residual (bool, optional, defaults to False) – Whether to use a parallel residual connection in the attention layer.

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

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

  • partial_rotary_factor (float, optional, defaults to 0.25) – The factor to scale the partial rotary embeddings by.

  • bos_token_id (int, optional, defaults to 0) – The id for the beginning of stream token.

  • eos_token_id (int, optional, defaults to 0) – The id for the end of stream token.

  • bits (int, optional) – The number of bits to quantize the model to. If None, the model is not quantized.

  • gradient_checkpointing (str, optional, defaults to “nothing_saveable”) – What to save during gradient checkpointing. Choose one of “nothing_saveable”, “first_half_saveable”, “full_saveable”.

get_partition_rules(fully_sharded_data_parallel: bool = True)[source]#

Get the partition rules for the model.

Parameters

fully_sharded_data_parallel (bool, optional, defaults to True) – Whether to use fully sharded data parallelism.

Returns

The partition rules.

Return type

tp.Tuple[tp.Tuple[str, PartitionSpec]]

property granted_freq_max_position_embedding: int#

Returns the maximum position embedding size specifically for frequency-based position embeddings.

If freq_max_position_embeddings is set, it returns that value. Otherwise, it falls back to max_position_embeddings.

Returns

The granted maximum position embedding size for frequency encoding.

Return type

int

property granted_mask_max_position_embedding: int#

Returns the maximum position embedding size specifically for mask-based position embeddings.

If mask_max_position_embeddings is set, it returns that value. Otherwise, it falls back to max_position_embeddings.

Returns

The granted maximum position embedding size for mask encoding.

Return type

int
