It is used to instantiate a NemotronH 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 NemotronH-v0.1 model. Args: vocab_size (`int`, *optional*, defaults to 131072): Vocabulary size of the NemotronH model. Defines the number of different tokens that can be represented by the `inputs_ids` passed when calling [`NemotronHModel`] tie_word_embeddings (`bool`, *optional*, defaults to `False`): Whether the model's input and output word embeddings should be tied. Note that this is only relevant if the model has an output word embedding layer. hidden_size (`int`, *optional*, defaults to 4096): Dimension of the hidden representations. intermediate_size (`int`, *optional*, defaults to 21504): Dimension of the MLP representations. num_hidden_layers (`int`, *optional*, defaults to 52): Number of hidden layers in the Transformer encoder. hybrid_override_pattern (`str`, *optional*, defaults to `"M-M-M-M*-M-M-M-M-M*-M-M-M-M-M*-M-M-M-M-M*-M-M-M-M-M-"`): The pattern of the hybrid model. The pattern is a string of characters where each character represents M: Mamba2, *: Attention, -: MLP num_attention_heads (`int`, *optional*, defaults to 32): Number of attention heads for each attention layer in the Transformer encoder. attention_head_dim (`int`, *optional*, defaults to 128): Dimension of each attention head. num_key_value_heads (`int`, *optional*, defaults to 8): This is the number of key_value heads that should be used to implement Grouped Query Attention. If `num_key_value_heads=num_attention_heads`, the model will use Multi Head Attention (MHA), if `num_key_value_heads=1` the model will use Multi Query Attention (MQA) otherwise GQA is used. mlp_hidden_act (`str`, *optional*, defaults to "relu2"): The non-linear activation function in the MLP layers. attention_bias (`bool`, *optional*, defaults to `False`): Whether to use bias in attention layers. mlp_bias (`bool`, *optional*, defaults to `False`): Whether to use bias in MLP layers. use_bias (`bool`, *optional*, defaults to `False`): Whether to use bias in the model. initializer_range (`float`, *optional*, defaults to 0.02): The standard deviation of the truncated_normal_initializer for initializing all weight matrices. layer_norm_epsilon (`float`, *optional*, defaults to 1e-5): The epsilon used by the layer normalization layers. residual_in_fp32 (`bool`, *optional*, defaults to `False`): Whether or not residuals should be in `float32`. If set to `False` residuals will keep the same `dtype` as the rest of the 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`. num_logits_to_keep (`int` or `None`, *optional*, defaults to 1): Number of prompt logits to calculate during generation. If `None`, all logits will be calculated. If an integer value, only last `num_logits_to_keep` logits will be calculated. pad_token_id (`int`, *optional*, defaults to 0): The id of the padding token. bos_token_id (`int`, *optional*, defaults to 1): The id of the "beginning-of-sequence" token. eos_token_id (`int`, *optional*, defaults to 2): The id of the "end-of-sequence" token. sliding_window (`int`, *optional*, defaults to None): Sliding window attention window size. max_position_embeddings (`int`, *optional*, defaults to 4096): The maximum sequence length that this model might ever be used with. attention_dropout (`float`, *optional*, defaults to 0.0): The dropout ratio for the attention probabilities. hidden_dropout (`float`, *optional*, defaults to 0.0): The dropout ratio for the hidden states. use_mamba_kernels (`bool`, *optional*, defaults to `True`): Flag indicating whether or not to use the fast mamba kernels. These are available only if `mamba-ssm` and `causal-conv1d` are installed, and the mamba modules are running on a CUDA device. ssm_state_size (`int`, *optional*, defaults to 128): The dimension of the mamba state space latents. mamba_num_heads (`int`, *optional*, defaults to 128): Number of heads in Mamba layers. mamba_n_groups (`int`, *optional*, defaults to 8): Number of groups in Mamba layers. mamba_head_dim (`int`, *optional*, defaults to 64): Dimension of each Mamba head. mamba_d_conv (`int`, *optional*, defaults to 4): The size of the mamba convolution kernel. mamba_expand (`int`, *optional*, defaults to 2): Expanding factor used to determine the mamba intermediate size. mamba_hidden_act (`str`, *optional*, defaults to "silu"): The non-linear activation function in the Mamba layers. mamba_dt_min (`float`, *optional*, defaults to 0.001): Minimum value for the time step in Mamba. mamba_dt_max (`float`, *optional*, defaults to 0.1): Maximum value for the time step in Mamba. mamba_dt_limit (`tuple`, *optional*, defaults to (0.0, float("inf"))): Limits for the time step in Mamba. mamba_dt_init_floor (`float`, *optional*, defaults to 1e-4): Floor value for time step initialization in Mamba. mamba_conv_bias (`bool`, *optional*, defaults to `True`): Whether to use bias in the convolution layer of the mamba mixer block. mamba_proj_bias (`bool`, *optional*, defaults to `False`): Whether to use bias in the input and output projections of the mamba mixer block. mamba_chunk_size (`int`, *optional*, defaults to 256): Size of chunks for Mamba processing. rescale_prenorm_residual (`bool`, *optional*, defaults to `True`): Whether to rescale the pre-normalization residual connections.
