- include modeling files in repo (8241db4f3c6c84eae0a3083473a91135f2401f69)
- include automap in config.json (0c2389f06d7159973efd6f8b8dbc214ef10cf719)
- use real transformers lib and have changes locally (42896b390130ca774884ddb4fadf0a6dcb613199)
- config jsons missing (7f5c1613bb14d2ad35786291e5d99adaa814527f)
- updated readme (c3bc1837336b3013f851476a946551c054bc3122)

+    This is the configuration class to store the configuration of a [`Kosmos2_5TextModel`]. It is used to instantiate a
+    KOSMOS-2.5 text decoder according to the specified arguments, defining the model architecture. Instantiating a
+    configuration with the defaults will yield a similar configuration to that of the text decoder of the KOSMOS-2.5
+    [microsoft/KOSMOS-2.5](https://huggingface.co/microsoft/KOSMOS-2.5) architecture.
+
+    Configuration objects inherit from [`PretrainedConfig`] and can be used to control the model outputs. Read the
+    documentation from [`PretrainedConfig`] for more information.

+            `inputs_ids` passed when calling [`Kosmos2_5Model`].
+        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

+        attention_heads (`int`, *optional*, defaults to 32):
+            Number of attention heads for each attention layer in the Transformer encoder.
+        activation_function (`str` or `function`, *optional*, defaults to `"gelu"`):
+            The non-linear activation function (function or string) in the encoder and pooler. If string, `"gelu"`,
+            `"relu"`, `"silu"` and `"gelu_new"` are supported.
+        dropout (`float`, *optional*, defaults to 0.1):
+            The dropout probability for all fully connected layers in the embeddings, encoder, and pooler.
+        attention_dropout (`float`, *optional*, defaults to 0.1):
+            The dropout ratio for the attention probabilities.
+        activation_dropout (`float`, *optional*, defaults to 0.0):
+            The dropout ratio for activations inside the fully connected layer.
+        layerdrop (`float`, *optional*, defaults to 0.0):
+            The LayerDrop probability for the decoder. See the [LayerDrop paper](see https://arxiv.org/abs/1909.11556)
+            for more details.
+        layer_norm_eps (`float`, *optional*, defaults to 1e-5):
+            The epsilon used by the layer normalization layers.
+        init_std (`float`, *optional*, defaults to 0.02):
+            The standard deviation of the truncated_normal_initializer for initializing all weight matrices.
+        scale_embedding (`bool`, *optional*, defaults to `True`):
+            Scale embeddings by diving by sqrt(embed_dim).
