It is used to instantiate31    an InternLM2 model according to the specified arguments, defining the model architecture. Instantiating a32    configuration with the defaults will yield a similar configuration to that of the InternLM2-7B.33 34    Configuration objects inherit from [`PretrainedConfig`] and can be used to control the model outputs. Read the35    documentation from [`PretrainedConfig`] for more information.36 37 38    Args:39        vocab_size (`int`, *optional*, defaults to 32000):40            Vocabulary size of the InternLM2 model.

If52            `num_key_value_heads=num_attention_heads`, the model will use Multi Head Attention (MHA), if53            `num_key_value_heads=1 the model will use Multi Query Attention (MQA) otherwise GQA is used. When54            converting a multi-head checkpoint to a GQA checkpoint, each group key and value head should be constructed55            by meanpooling all the original heads within that group.

InternLM2 supports up to 32768 tokens.62        initializer_range (`float`, *optional*, defaults to 0.02):63            The standard deviation of the truncated_normal_initializer for initializing all weight matrices.64        rms_norm_eps (`float`, *optional*, defaults to 1e-06):65            The epsilon used by the rms normalization layers.66        use_cache (`bool`, *optional*, defaults to `True`):67            Whether or not the model should return the last key/values attentions (not used by all models).

This value is necessary to ensure exact reproducibility79            of the pretraining results.

Currently supports two scaling87            strategies: linear and dynamic. Their scaling factor must be a float greater than 1. The expected format is88            `{"type": strategy name, "factor": scaling factor}`. When using this flag, don't update89            `max_position_embeddings` to the expected new maximum.
