- logger = logging.get_logger(__name__)
- class AltCLIPTextConfig(PretrainedConfig):
- r"""
- This is the configuration class to store the configuration of a [`AltCLIPTextModel`]. It is used to instantiate a
- AltCLIP text 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 AltCLIP
- [BAAI/AltCLIP](https://huggingface.co/BAAI/AltCLIP) architecture.
- Configuration objects inherit from [`PretrainedConfig`] and can be used to control the model outputs. Read the
- documentation from [`PretrainedConfig`] for more information.
- Args:
- vocab_size (`int`, *optional*, defaults to 250002):
- Vocabulary size of the AltCLIP model. Defines the number of different tokens that can be represented by the
- `inputs_ids` passed when calling [`AltCLIPTextModel`].
- hidden_size (`int`, *optional*, defaults to 1024):
- 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.

- The dropout ratio for the attention probabilities.
- max_position_embeddings (`int`, *optional*, defaults to 514):
- 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 1):
- The vocabulary size of the `token_type_ids` passed when calling [`AltCLIPTextModel`]
- initializer_range (`float`, *optional*, defaults to 0.02):
- The standard deviation of the truncated_normal_initializer for initializing all weight matrices.
- initializer_factor (`float`, *optional*, defaults to 0.02):
- A factor for initializing all weight matrices (should be kept to 1, used internally for initialization
- testing).

- The epsilon used by the layer normalization layers.
- pad_token_id (`int`, *optional*, defaults to 1): The id of the *padding* token.

- eos_token_id (`Union[int, list[int]]`, *optional*, defaults to 2):
- The id of the *end-of-sequence* token. Optionally, use a list to set multiple *end-of-sequence* tokens.
- position_embedding_type (`str`, *optional*, defaults to `"absolute"`):
- Type of position embedding. Choose one of `"absolute"`, `"relative_key"`, `"relative_key_query"`. For
- positional embeddings use `"absolute"`. For more information on `"relative_key"`, please refer to
- [Self-Attention with Relative Position Representations (Shaw et al.)](https://huggingface.co/papers/1803.02155).
- For more information on `"relative_key_query"`, please refer to *Method 4* in [Improve Transformer Models
- with Better Relative Position Embeddings (Huang et al.)](https://huggingface.co/papers/2009.13658).
- 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`.
- project_dim (`int`, *optional*, defaults to 768):
- The dimensions of the teacher model before the mapping layer.
