class PlugNLGConfig(PlugNLUConfig):
    """
    This is the configuration class to store the configuration of a [`PlugModel`]. It is used to instantiate a
    PLUG understanding 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 PLUG
    [PLUG](https://modelscope.cn/models/damo/nlp_plug_text-generation_27B/summary) architecture.

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

    Args:
        vocab_size (`int`, *optional*, defaults to 21504):
            Padded vocabulary size of the PLUG model for vocab tensor parallel. Defines the number of different tokens
            that can be represented by the `inputs_ids` passed when calling [`PlugModel`].
        original_vocab_size (`int`, *optional*, defaults to 21128):
            True vocabulary size of the PLUG model. Defines the number of different tokens that can be represented.
        hidden_size (`int`, *optional*, defaults to 8192):
            Dimensionality of the encoder layers and the pooler layer.
        num_hidden_layers (`int`, *optional*, defaults to 24):
            Number of hidden layers in the Transformer encoder.
        dec_hidden_layers (`int`, *optional*, defaults to 6):
            Number of hidden layers in the Transformer decoder.
        num_attention_heads (`int`, *optional*, defaults to 128):
            Number of attention heads for each attention layer in the Transformer encoder.
        intermediate_size (`int`, *optional*, defaults to 32768):
            Dimensionality of the "intermediate" (i.e., feed-forward) layer in the Transformer encoder.
        hidden_act (`str`, *optional*, defaults to `"gelu"`):
            The non-linear activation function (function or string) in the encoder and pooler. If string, `"gelu"`,
            `"relu"`, `"selu"` and `"gelu_new"` are supported.
        hidden_dropout_prob (`float`, *optional*, defaults to 0.1):
            The dropout ratio for all fully connected layers in the embeddings, encoder, and pooler.
        attention_probs_dropout_prob (`float`, *optional*, defaults to 0.1):
            The dropout ratio for the Transformer Attention.
        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., 512 or 1024 or 2048).
        type_vocab_size (`int`, *optional*, defaults to 3):
            The vocabulary size of the `token_type_ids` passed when calling [`PlugModel`].
        initializer_range (`float`, *optional*, defaults to 0.00707):
            The standard deviation of the truncated_normal_initializer for initializing all weight matrices.
        lr_decay_style (`str`, *optional*, defaults to 'linear'):
            The decay style of learning rate during fine-tunining. If string, `"linear"`, `"cosine"`, `"exponential"`,
            `"constant"`, `"None"` are supported.
        weight_decay (`float`, *optional*, defaults to 1e-2):
            Decoupled weight decay to apply.
        clip_grad (`float`, *optional*, defaults to 1.0):
            Maximum gradient norm for gradient clipping.
        warmup (`float`, *optional*, defaults to 0.01):
            Ratio of total training steps used for a linear warmup from 0 to `learning_rate`.
        pre_ln (`boolean`, *optional*, defaults to `True`):
            Whether or not to apply LayerNorm to the input instead of the output in the blocks.
        fp16 (`boolean`, *optional*, defaults to `True`):
            Whether to use fp16 16-bit (mixed) precision training instead of 32-bit training.
        fp32_layernorm (`boolean`, *optional*, defaults to `True`):
            Whether to use fp32 32-bit precision LayerNorm training while the argument `fp16` set to `True`.
        fp32_embedding (`boolean`, *optional*, defaults to `False`):
            Whether to use fp32 32-bit precision Embedding training while the argument `fp16` set to `True`.
        fp32_tokentypes (`boolean`, *optional*, defaults to `False`):
            Whether to use fp32 32-bit precision token types training while the argument `fp16` set to `True`.
        layernorm_epsilon (`float`, *optional*, defaults to 1e-5):
            The epsilon to use in the layer normalization layers.
        attn_separate (`boolean`, *optional*, defaults to `False`):
            Whether or not to separate query-key-value to query, key, value in the Attention.

    Example:

    >>> # The PLUG model has 27B parameters and usually need to run on multiple GPUs. The example given
    >>> # here only initializes a slice of the model on a single GPU.
    >>> # Check out the [`~DistributedPipeline.__init__`] method to initialize entire PLUG model.
    >>> from modelscope.models.nlp.plug import PlugNLGConfig, PlugModel

    >>> # Initializing a Plug configuration
    >>> configuration = PlugNLGConfig()

    >>> # Initializing a model from the configuration
    >>> model = PlugModel(configuration)

    >>> # Accessing the model configuration
