33
+ This is the configuration class to store the configuration of a [`Phi3VModel`]. It is used to instantiate a Phi-3
34
+ model according to the specified arguments, defining the model architecture. Instantiating a configuration with the
35
+ defaults will yield a similar configuration to that of the
36
+ [microsoft/Phi-3-vision-128k-instruct](https://huggingface.co/microsoft/Phi-3-vision-128k-instruct).
37
+
38
+ Configuration objects inherit from [`PretrainedConfig`] and can be used to control the model outputs. Read the
39
+ documentation from [`PretrainedConfig`] for more information.
40
+
41
+ Args:
42
+ vocab_size (`int`, *optional*, defaults to 32064):
43
+ Vocabulary size of the Phi-3-V model. Defines the number of different tokens that can be represented by the
44
+ `inputs_ids` passed when calling [`Phi3VModel`].
45
+ hidden_size (`int`, *optional*, defaults to 3072):
46
+ Dimension of the hidden representations.
47
+ intermediate_size (`int`, *optional*, defaults to 8192):
48
+ Dimension of the MLP representations.
49
+ num_hidden_layers (`int`, *optional*, defaults to 32):
50
+ Number of hidden layers in the Transformer decoder.
51
+ num_attention_heads (`int`, *optional*, defaults to 32):
52
+ Number of attention heads for each attention layer in the Transformer decoder.
53
+ num_key_value_heads (`int`, *optional*):
54
+ This is the number of key_value heads that should be used to implement Grouped Query Attention. If
55
+ `num_key_value_heads=num_attention_heads`, the model will use Multi Head Attention (MHA), if
56
+ `num_key_value_heads=1 the model will use Multi Query Attention (MQA) otherwise GQA is used. When
57
+ converting a multi-head checkpoint to a GQA checkpoint, each group key and value head should be constructed
58
+ by meanpooling all the original heads within that group. For more details checkout [this
59
+ paper](https://arxiv.org/pdf/2305.13245.pdf). If it is not specified, will default to
60
+ `num_attention_heads`.
61
+ resid_pdrop (`float`, *optional*, defaults to 0.0):
62
+ Dropout probability for mlp outputs.
63
+ embd_pdrop (`int`, *optional*, defaults to 0.0):
64
+ The dropout ratio for the embeddings.
65
+ attention_dropout (`float`, *optional*, defaults to 0.0):
66
+ The dropout ratio after computing the attention scores.
67
+ hidden_act (`str` or `function`, *optional*, defaults to `"silu"`):
68
+ The non-linear activation function (function or string) in the decoder.
69
+ max_position_embeddings (`int`, *optional*, defaults to 4096):
70
+ The maximum sequence length that this model might ever be used with.
71
+ original_max_position_embeddings (`int`, *optional*, defaults to 4096):
72
+ The maximum sequence length that this model was trained with. This is used to determine the size of the
73
+ original RoPE embeddings when using long scaling.
74
+ initializer_range (`float`, *optional*, defaults to 0.02):
75
+ The standard deviation of the truncated_normal_initializer for initializing all weight matrices.
76
+ rms_norm_eps (`float`, *optional*, defaults to 1e-05):
77
+ The epsilon value used for the RMSNorm.
78
+ use_cache (`bool`, *optional*, defaults to `True`):
79
+ Whether or not the model should return the last key/values attentions (not used by all models). Only
80
+ relevant if `config.is_decoder=True`. Whether to tie weight embeddings or not.
81
+ tie_word_embeddings (`bool`, *optional*, defaults to `False`):
82
+ Whether to tie weight embeddings
83
+ rope_theta (`float`, *optional*, defaults to 10000.0):
84
+ The base period of the RoPE embeddings.
85
+ rope_scaling (`dict`, *optional*):
86
+ The scaling strategy for the RoPE embeddings. If `None`, no scaling is applied. If a dictionary, it must
87
+ contain the following keys: `type`, `short_factor` and `long_factor`. The `type` must be either `su` or `yarn` and
88
+ the `short_factor` and `long_factor` must be lists of numbers with the same length as the hidden size
89
+ divided by the number of attention heads divided by 2.
90
+ bos_token_id (`int`, *optional*, defaults to 1):
91
+ The id of the "beginning-of-sequence" token.
92
+ eos_token_id (`int`, *optional*, defaults to 32000):
93
+ The id of the "end-of-sequence" token.
94
+ pad_token_id (`int`, *optional*, defaults to 32000):
95
+ The id of the padding token.
96
+ sliding_window (`int`, *optional*):
97
+ Sliding window attention window size. If `None`, no sliding window is applied.
98
+ embd_layer (`str`, *optional*, defaults to `"default"`):
99
+ The embedding layer to use. Can be either `"default"` or `"image"`. "default" uses the standard embedding for text.

1254
+
1255

1258

1261
+
1262
+ - 1 for tokens that are **not masked**,
1263

+ `past_key_values`).
1272

1273

+
1283
+ [What are position IDs?](../glossary#position-ids)
1284

1285
+ Pre-computed hidden-states (key and values in the self-attention blocks and in the cross-attention
1286
+ blocks) that can be used to speed up sequential decoding. This typically consists in the `past_key_values`
1287
+ returned by the model at a previous stage of decoding, when `use_cache=True` or `config.use_cache=True`.
1288
+
1289
+ Two formats are allowed:
1290
+ - a [`~cache_utils.Cache`] instance;
1291
+ - Tuple of `tuple(torch.FloatTensor)` of length `config.n_layers`, with each tuple having 2 tensors of
1292
+ shape `(batch_size, num_heads, sequence_length, embed_size_per_head)`). This is also known as the legacy
1293
+ cache format.
1294
+
1295
+ The model will output the same cache format that is fed as input. If no `past_key_values` are passed, the
1296
+ legacy cache format will be returned.
1297
+
1298
+ If `past_key_values` are used, the user can optionally input only the last `input_ids` (those that don't
1299
+ have their past key value states given to this model) of shape `(batch_size, 1)` instead of all `input_ids`
1300
+ of shape `(batch_size, sequence_length)`.
1301
+ inputs_embeds (`torch.FloatTensor` of shape `(batch_size, sequence_length, hidden_size)`, *optional*):
1302
+ Optionally, instead of passing `input_ids` you can choose to directly pass an embedded representation. This
1303
+ is useful if you want more control over how to convert `input_ids` indices into associated vectors than the
1304
+ model's internal embedding lookup matrix.
1305
+ pixel_values (`torch.FloatTensor` of shape `(batch_size, num_channels, image_size, image_size)):
1306
+ The tensors corresponding to the input images. Pixel values can be obtained using [`AutoImageProcessor`].
1307
+ See [`Phi3ImageProcessor.__call__`] for details.
1308
+ image_sizes (`torch.LongTensor` of shape `(batch_size, 2)`, *optional*):
1309
+ The sizes of the images in the batch, being (height, width) for each image.
1310
+ use_cache (`bool`, *optional*):
1311
+ If set to `True`, `past_key_values` key value states are returned and can be used to speed up decoding (see
1312
+ `past_key_values`).
1313
+ output_attentions (`bool`, *optional*):
1314
+ Whether or not to return the attentions tensors of all attention layers. See `attentions` under returned
1315
+ tensors for more detail.
1316
