+
41
+ This model inherits from [`FlaxPreTrainedModel`]. Check the superclass documentation for the generic methods the
42
+ library implements for all its model (such as downloading, saving and converting weights from PyTorch models)
43
+
44
+ This model is also a
45
+ [flax.linen.Module](https://flax.readthedocs.io/en/latest/api_reference/flax.linen/module.html) subclass. Use it as
46
+ a regular Flax linen Module and refer to the Flax documentation for all matter related to general usage and
47
+ behavior.
48
+
49
+ Finally, this model supports inherent JAX features such as:
50
+
51
+ - [Just-In-Time (JIT) compilation](https://jax.readthedocs.io/en/latest/jax.html#just-in-time-compilation-jit)
52
+ - [Automatic Differentiation](https://jax.readthedocs.io/en/latest/jax.html#automatic-differentiation)
53
+ - [Vectorization](https://jax.readthedocs.io/en/latest/jax.html#vectorization-vmap)
54
+ - [Parallelization](https://jax.readthedocs.io/en/latest/jax.html#parallelization-pmap)
55
+
56
+ Parameters:
57
+ config ([`Dinov2Config`]): Model configuration class with all the parameters of the model.
58
+ Initializing with a config file does not load the weights associated with the model, only the
59
+ configuration. Check out the [`~FlaxPreTrainedModel.from_pretrained`] method to load the model weights.
60
+ dtype (`jax.numpy.dtype`, *optional*, defaults to `jax.numpy.float32`):
61
+ The data type of the computation. Can be one of `jax.numpy.float32`, `jax.numpy.float16` (on GPUs) and
62
+ `jax.numpy.bfloat16` (on TPUs).
63
+
64
+ This can be used to enable mixed-precision training or half-precision inference on GPUs or TPUs. If
65
+ specified all the computation will be performed with the given `dtype`.
66
+
67
+ **Note that this only specifies the dtype of the computation and does not influence the dtype of model
68
+ parameters.**
69
+
70
+ If you wish to change the dtype of the model parameters, see [`~FlaxPreTrainedModel.to_fp16`] and
71
+ [`~FlaxPreTrainedModel.to_bf16`].

74

75
+ Args:
76
+ pixel_values (`numpy.ndarray` of shape `(batch_size, num_channels, height, width)`):
77
+ Pixel values. Pixel values can be obtained using [`AutoImageProcessor`]. See [`Dinov2ImageProcessor.__call__`]
78
+ for details.
79
+
80
+ output_attentions (`bool`, *optional*):
81
+ Whether or not to return the attentions tensors of all attention layers. See `attentions` under returned
82
+ tensors for more detail.
83
+ output_hidden_states (`bool`, *optional*):
84

86

29
+ This is the configuration class to store the configuration of a [`Dinov2WithRegistersModel`]. It is used to instantiate an
30
+ Dinov2WithRegisters model according to the specified arguments, defining the model architecture. Instantiating a configuration
31
+ with the defaults will yield a similar configuration to that of the DINOv2 with Registers
32
+ [facebook/dinov2-with-registers-base](https://huggingface.co/facebook/dinov2-with-registers-base) architecture.
33
+
34
+ Configuration objects inherit from [`PretrainedConfig`] and can be used to control the model outputs. Read the
35
+ documentation from [`PretrainedConfig`] for more information.
36
+
37
+ Args:
38
+ hidden_size (`int`, *optional*, defaults to 768):
39
+ Dimensionality of the encoder layers and the pooler layer.

+ num_hidden_layers (`int`, *optional*, defaults to 12):
41
+ Number of hidden layers in the Transformer encoder.
42
+ num_attention_heads (`int`, *optional*, defaults to 12):
43
+ Number of attention heads for each attention layer in the Transformer encoder.
44
+ mlp_ratio (`int`, *optional*, defaults to 4):
45
+ Ratio of the hidden size of the MLPs relative to the `hidden_size`.
46
+ hidden_act (`str` or `function`, *optional*, defaults to `"gelu"`):
47
+ The non-linear activation function (function or string) in the encoder and pooler. If string, `"gelu"`,
48
+ `"relu"`, `"selu"` and `"gelu_new"` are supported.
49
+ hidden_dropout_prob (`float`, *optional*, defaults to 0.0):
50
+ The dropout probability for all fully connected layers in the embeddings, encoder, and pooler.
51
+ attention_probs_dropout_prob (`float`, *optional*, defaults to 0.0):
52
+ The dropout ratio for the attention probabilities.
53
+ initializer_range (`float`, *optional*, defaults to 0.02):
54
+ The standard deviation of the truncated_normal_initializer for initializing all weight matrices.
55
+ layer_norm_eps (`float`, *optional*, defaults to 1e-06):
56
+ The epsilon used by the layer normalization layers.
57
+ image_size (`int`, *optional*, defaults to 224):
58
+ The size (resolution) of each image.
59
+ patch_size (`int`, *optional*, defaults to 16):
60
+ The size (resolution) of each patch.
61
+ num_channels (`int`, *optional*, defaults to 3):
62
+ The number of input channels.
63
+ qkv_bias (`bool`, *optional*, defaults to `True`):
64
+ Whether to add a bias to the queries, keys and values.
65
+ layerscale_value (`float`, *optional*, defaults to 1.0):
66
+ Initial value to use for layer scale.
67
+ drop_path_rate (`float`, *optional*, defaults to 0.0):
68
+ Stochastic depth rate per sample (when applied in the main path of residual layers).
69
+ use_swiglu_ffn (`bool`, *optional*, defaults to `False`):
70
+ Whether to use the SwiGLU feedforward neural network.
71
+ num_register_tokens (`int`, *optional*, defaults to 4):
72
+ Number of register tokens to use.
73
+ out_features (`list[str]`, *optional*):
74
+ If used as backbone, list of features to output. Can be any of `"stem"`, `"stage1"`, `"stage2"`, etc.
75
+ (depending on how many stages the model has). If unset and `out_indices` is set, will default to the
76
+ corresponding stages. If unset and `out_indices` is unset, will default to the last stage. Must be in the
77
+ same order as defined in the `stage_names` attribute.
78
+ out_indices (`list[int]`, *optional*):
79
+ If used as backbone, list of indices of features to output. Can be any of 0, 1, 2, etc. (depending on how
80
+ many stages the model has). If unset and `out_features` is set, will default to the corresponding stages.
81
+ If unset and `out_features` is unset, will default to the last stage. Must be in the
82
+ same order as defined in the `stage_names` attribute.
83
+ apply_layernorm (`bool`, *optional*, defaults to `True`):
84
+ Whether to apply layer normalization to the feature maps in case the model is used as backbone.
85
+ reshape_hidden_states (`bool`, *optional*, defaults to `True`):
86
+ Whether to reshape the feature maps to 4D tensors of shape `(batch_size, hidden_size, height, width)` in
87
+ case the model is used as backbone. If `False`, the feature maps will be 3D tensors of shape `(batch_size,

+ class Dinov2WithRegistersConfig(BackboneConfigMixin, PretrainedConfig):
42
+ r"""
43
+ This is the configuration class to store the configuration of a [`Dinov2WithRegistersModel`]. It is used to instantiate an
44
+ Dinov2WithRegisters model according to the specified arguments, defining the model architecture. Instantiating a configuration
45
+ with the defaults will yield a similar configuration to that of the DINOv2 with Registers
46
+ [facebook/dinov2-with-registers-base](https://huggingface.co/facebook/dinov2-with-registers-base) architecture.
47
+
48
+ Configuration objects inherit from [`PretrainedConfig`] and can be used to control the model outputs. Read the
49
+ documentation from [`PretrainedConfig`] for more information.

28
+ This is the configuration class to store the configuration of a [`DINOv3ConvNextModel`]. It is used to instantiate an
29
+ DINOv3ConvNext model according to the specified arguments, defining the model architecture. Instantiating a configuration
30
+ with the defaults will yield a similar configuration to that of the DINOv3ConvNext
31
+ [facebook/dinov3-convnext-tiny-pretrain-lvd1689m](https://huggingface.co/facebook/dinov3-convnext-tiny-pretrain-lvd1689m) architecture.
32
+
33
+ Configuration objects inherit from [`PretrainedConfig`] and can be used to control the model outputs. Read the
34
+ documentation from [`PretrainedConfig`] for more information.
35
+
36
+ Args:
37
+ num_channels (`int`, *optional*, defaults to 3):
38
+ The number of input channels.
39
+ hidden_sizes (`list[int]`, *optional*, defaults to [96, 192, 384, 768]):
40
+ Dimensionality (hidden size) at each stage.
41
+ depths (`list[int]`, *optional*, defaults to [3, 3, 9, 3]):
42
+ The number of layers for each stage.
43
+ hidden_act (`str` or `function`, *optional*, defaults to `"gelu"`):
44
+ The non-linear activation function (function or string) in each block. If string, `"gelu"`, `"relu"`,
45
+ `"selu"` and `"gelu_new"` are supported.
46
+ initializer_range (`float`, *optional*, defaults to 0.02):
47
+ The standard deviation of the truncated_normal_initializer for initializing all weight matrices.
48
+ layer_norm_eps (`float`, *optional*, defaults to 1e-06):
49
+ The epsilon used by the layer normalization layers.
50
+ layer_scale_init_value (`float`, *optional*, defaults to 1e-06):
51
+ The initial value for the layer scale.
52
+ drop_path_rate (`float`, *optional*, defaults to 0.0):
53
+ The drop rate for stochastic depth.
54
+ image_size (`int`, *optional*, defaults to 224):
55
+ The size (resolution) of input images.
56
+
57
+ Example:
58
+ ```python
59
+ >>> from transformers import DINOv3ConvNextConfig, DINOv3ConvNextModel
60
+
61
+ >>> # Initializing a DINOv3ConvNext (tiny variant) style configuration

30
+ This is the configuration class to store the configuration of a [`DistilBertModel`] or a [`TFDistilBertModel`]. It
31
+ is used to instantiate a DistilBERT model according to the specified arguments, defining the model architecture.
32
+ Instantiating a configuration with the defaults will yield a similar configuration to that of the DistilBERT
33
+ [distilbert-base-uncased](https://huggingface.co/distilbert-base-uncased) architecture.
34
+
35
+ Configuration objects inherit from [`PretrainedConfig`] and can be used to control the model outputs. Read the
36
+ documentation from [`PretrainedConfig`] for more information.
37
+
38
+ Args:
39
+ vocab_size (`int`, *optional*, defaults to 30522):
40
+ Vocabulary size of the DistilBERT model. Defines the number of different tokens that can be represented by
41
+ the `inputs_ids` passed when calling [`DistilBertModel`] or [`TFDistilBertModel`].
42
+ max_position_embeddings (`int`, *optional*, defaults to 512):
43
+ The maximum sequence length that this model might ever be used with. Typically set this to something large
44
+ just in case (e.g., 512 or 1024 or 2048).
45
+ sinusoidal_pos_embds (`boolean`, *optional*, defaults to `False`):
46
+ Whether to use sinusoidal positional embeddings.
47
+ n_layers (`int`, *optional*, defaults to 6):
48
+ Number of hidden layers in the Transformer encoder.
49
+ n_heads (`int`, *optional*, defaults to 12):
50
+ Number of attention heads for each attention layer in the Transformer encoder.
51
+ dim (`int`, *optional*, defaults to 768):
52
+ Dimensionality of the encoder layers and the pooler layer.
53
+ hidden_dim (`int`, *optional*, defaults to 3072):
54
+ The size of the "intermediate" (often named feed-forward) layer in the Transformer encoder.
55
+ dropout (`float`, *optional*, defaults to 0.1):
56
+ The dropout probability for all fully connected layers in the embeddings, encoder, and pooler.
57
+ attention_dropout (`float`, *optional*, defaults to 0.1):
58
+ The dropout ratio for the attention probabilities.
59
+ activation (`str` or `Callable`, *optional*, defaults to `"gelu"`):
60
+ The non-linear activation function (function or string) in the encoder and pooler. If string, `"gelu"`,
61
+ `"relu"`, `"silu"` and `"gelu_new"` are supported.
62
+ initializer_range (`float`, *optional*, defaults to 0.02):
63
+ The standard deviation of the truncated_normal_initializer for initializing all weight matrices.
64
+ qa_dropout (`float`, *optional*, defaults to 0.1):
65
+ The dropout probabilities used in the question answering model [`DistilBertForQuestionAnswering`].
66
+ seq_classif_dropout (`float`, *optional*, defaults to 0.2):
67
+ The dropout probabilities used in the sequence classification and the multiple choice model
68
+ [`DistilBertForSequenceClassification`].

48
+ This model inherits from [`FlaxPreTrainedModel`]. Check the superclass documentation for the generic methods the
49
+ library implements for all its model (such as downloading, saving and converting weights from PyTorch models)
50
+
51
+ This model is also a
52
+ [flax.linen.Module](https://flax.readthedocs.io/en/latest/api_reference/flax.linen/module.html) subclass. Use it as
53
+ a regular Flax linen Module and refer to the Flax documentation for all matter related to general usage and
54
+ behavior.
55
+
56
+ Finally, this model supports inherent JAX features such as:
57
+
58
+ - [Just-In-Time (JIT) compilation](https://jax.readthedocs.io/en/latest/jax.html#just-in-time-compilation-jit)
59
+ - [Automatic Differentiation](https://jax.readthedocs.io/en/latest/jax.html#automatic-differentiation)
60
+ - [Vectorization](https://jax.readthedocs.io/en/latest/jax.html#vectorization-vmap)
61
+ - [Parallelization](https://jax.readthedocs.io/en/latest/jax.html#parallelization-pmap)
62
+
63
+ Parameters:
64
+ config ([`DistilBertConfig`]): Model configuration class with all the parameters of the model.
65
+ Initializing with a config file does not load the weights associated with the model, only the
66
+ configuration. Check out the [`~PreTrainedModel.from_pretrained`] method to load the model weights.

499
+ <Tip>
500
+
501
+ TensorFlow models and layers in `transformers` accept two formats as input:
502
+
503
+ - having all inputs as keyword arguments (like PyTorch models), or
504
+ - having all inputs as a list, tuple or dict in the first positional argument.
505
+
506
+ The reason the second format is supported is that Keras methods prefer this format when passing inputs to models
507
+ and layers. Because of this support, when using methods like `model.fit()` things should "just work" for you - just
508
+ pass your inputs and labels in any format that `model.fit()` supports! If, however, you want to use the second
509
+ format outside of Keras methods like `fit()` and `predict()`, such as when creating your own layers or models with
510
+ the Keras `Functional` API, there are three possibilities you can use to gather all the input Tensors in the first
511
+ positional argument:
512
+
513
+ - a single Tensor with `input_ids` only and nothing else: `model(input_ids)`
514
+ - a list of varying length with one or several input Tensors IN THE ORDER given in the docstring:
515
+ `model([input_ids, attention_mask])` or `model([input_ids, attention_mask, token_type_ids])`
516
+ - a dictionary with one or several input Tensors associated to the input names given in the docstring:
517
+ `model({"input_ids": input_ids, "token_type_ids": token_type_ids})`
518
+
519
+ Note that when creating models and layers with
520
+ [subclassing](https://keras.io/guides/making_new_layers_and_models_via_subclassing/) then you don't need to worry
521
+ about any of this, as you can just pass inputs like you would to any other Python function!
522
+
523
+ </Tip>
524
+
525
+ Parameters:
526
+ config ([`DistilBertConfig`]): Model configuration class with all the parameters of the model.
527
+ Initializing with a config file does not load the weights associated with the model, only the
528
+ configuration. Check out the [`~PreTrainedModel.from_pretrained`] method to load the model weights.

536

+ [What are input IDs?](../glossary#input-ids)
540
+ attention_mask (`Numpy array` or `tf.Tensor` of shape `({0})`, *optional*):

542

543
+ - 1 for tokens that are **not masked**,
544
+ - 0 for tokens that are **masked**.

549

568

47
+ sep_token (`str`, *optional*, defaults to `"[SEP]"`):

49

50

55

58

59
+ clean_text (`bool`, *optional*, defaults to `True`):
60

61
+ whitespaces by the classic one.
62
+ tokenize_chinese_chars (`bool`, *optional*, defaults to `True`):
63

65
+ strip_accents (`bool`, *optional*):

67

+ rope_scaling (`Dict`, *optional*):
62
+ Dictionary containing the scaling configuration for the RoPE embeddings.
63
+ NOTE: if you apply new rope type and you expect the model to work on longer `max_position_embeddings`, we recommend you to update this value accordingly.
64
+ Doge family of small models use `{ 'rope_type': 'dynamic', 'factor': 4.0, 'original_max_position_embeddings': 2048 }` as the default value.
65
+ Expected contents:
66
+ `rope_type` (`str`):
67

68
+ `factor` (`float`, *optional*):
69
+ Used with all rope types except 'default'. The scaling factor to apply to the RoPE embeddings.

90
+ `low_freq_factor` (`float`, *optional*):
91
+ Only used with 'llama3'. Scaling factor applied to low frequency components of the RoPE
92

96
+ num_key_value_heads (`int`, *optional*):
97
+ This is the number of key_value heads that should be used to implement Grouped Query Attention.
98
+ If `num_key_value_heads=num_attention_heads`, the model will use Multi Head Attention (MHA), if
99
+ `num_key_value_heads=1` the model will use Multi Query Attention (MQA) otherwise GQA is used.
100
+ When converting a multi-head checkpoint to a GQA checkpoint, each group key and value head should be constructed by meanpooling all the original heads within that group.
101
+ For more details checkout [this paper](https://arxiv.org/pdf/2305.13245.pdf).
102
+ If it is not specified, will default to `num_attention_heads`.

+ Number of selected experts to route per-token.
119
+ norm_topk_prob (`bool`, *optional*, defaults to `False`):
120
+ Whether to normalize the topk probabilities.
121
+ output_router_logits (`bool`, *optional*, defaults to `False`):

126
+ If `num_key_value_heads=num_attention_heads`, the model will use Multi Head Attention (MHA), if

24
+ class DonutSwinConfig(PretrainedConfig):
25
+ r"""
26
+ This is the configuration class to store the configuration of a [`DonutSwinModel`]. It is used to instantiate a
27
+ Donut model according to the specified arguments, defining the model architecture. Instantiating a configuration
28
+ with the defaults will yield a similar configuration to that of the Donut
29
+ [naver-clova-ix/donut-base](https://huggingface.co/naver-clova-ix/donut-base) architecture.
30
+
31
+ Configuration objects inherit from [`PretrainedConfig`] and can be used to control the model outputs. Read the
32
+ documentation from [`PretrainedConfig`] for more information.
33
+
34
+ Args:
35
+ image_size (`int`, *optional*, defaults to 224):
36
+ The size (resolution) of each image.
37
+ patch_size (`int`, *optional*, defaults to 4):
38
+ The size (resolution) of each patch.
39
+ num_channels (`int`, *optional*, defaults to 3):
40
+ The number of input channels.
41
+ embed_dim (`int`, *optional*, defaults to 96):
42
+ Dimensionality of patch embedding.
43
+ depths (`list(int)`, *optional*, defaults to `[2, 2, 6, 2]`):
44
+ Depth of each layer in the Transformer encoder.
45
+ num_heads (`list(int)`, *optional*, defaults to `[3, 6, 12, 24]`):
46
+ Number of attention heads in each layer of the Transformer encoder.
47
+ window_size (`int`, *optional*, defaults to 7):
48
+ Size of windows.
49
+ mlp_ratio (`float`, *optional*, defaults to 4.0):
50
+ Ratio of MLP hidden dimensionality to embedding dimensionality.
51
+ qkv_bias (`bool`, *optional*, defaults to `True`):
52
+ Whether or not a learnable bias should be added to the queries, keys and values.
53
+ hidden_dropout_prob (`float`, *optional*, defaults to 0.0):
54
+ The dropout probability for all fully connected layers in the embeddings and encoder.
55
+ attention_probs_dropout_prob (`float`, *optional*, defaults to 0.0):
56
+ The dropout ratio for the attention probabilities.
57
+ drop_path_rate (`float`, *optional*, defaults to 0.1):
58
+ Stochastic depth rate.
59
+ hidden_act (`str` or `function`, *optional*, defaults to `"gelu"`):
60
+ The non-linear activation function (function or string) in the encoder. If string, `"gelu"`, `"relu"`,
61
+ `"selu"` and `"gelu_new"` are supported.
62
+ use_absolute_embeddings (`bool`, *optional*, defaults to `False`):
63
+ Whether or not to add absolute position embeddings to the patch embeddings.
64
+ initializer_range (`float`, *optional*, defaults to 0.02):
65
+ The standard deviation of the truncated_normal_initializer for initializing all weight matrices.
66
+ layer_norm_eps (`float`, *optional*, defaults to 1e-05):
67
+ The epsilon used by the layer normalization layers.
68
+
69
+ Example:
70
+
71
+ ```python
72
+ >>> from transformers import DonutSwinConfig, DonutSwinModel
73
+
74
+ >>> # Initializing a Donut naver-clova-ix/donut-base style configuration

23
+ r"""
24
+ This is the configuration class to store the configuration of a [`Dots1Model`]. It is used to instantiate a
25
+ `dots.llm1` model according to the specified arguments, defining the model architecture. Instantiating a
26
+ configuration with the defaults will yield a similar configuration to that of
27
+ [rednote-hilab/dots.llm1.base](https://huggingface.co/rednote-hilab/dots.llm1.base).
28
+
29
+ Configuration objects inherit from [`PretrainedConfig`] and can be used to control the model outputs. Read the
30
+ documentation from [`PretrainedConfig`] for more information.
31
+
32
+ Args:
33
+ vocab_size (`int`, *optional*, defaults to 152064):

35
+ `input_ids` passed when calling [`Dots1Model`].
36
+ hidden_size (`int`, *optional*, defaults to 4608):
37
+ Dimension of the hidden representations.

46
+ num_key_value_heads (`int`, *optional*, defaults to 32):
47
+ Number of key/value heads for Grouped Query Attention. If `num_key_value_heads=num_attention_heads`, Multi
48
+ Head Attention (MHA) is used. If `num_key_value_heads=1`, Multi Query Attention (MQA) is used. Otherwise,
49
+ Grouped Query Attention (GQA) is used. If not specified, defaults to `num_attention_heads`.
50
+ n_shared_experts (`int`, *optional*, default=None):
51
+ Number of shared experts. None means dense model.
52
+ n_routed_experts (`int`, *optional*, default=None):
53
+ Number of routed experts. None means dense model.
54
+ n_group (`int`, *optional*, defaults to 1):
55
+ Number of groups for routed experts.
56
+ topk_group (`int`, *optional*, defaults to 1):
57
+ Number of selected groups for each token (selected experts only within `topk_group` groups).
58
+ num_experts_per_tok (`int`, *optional*, default=None):
59
+ Number of selected experts. None means dense model.
60
+ first_k_dense_replace (`int`, *optional*, defaults to 0):
61
+ Number of dense layers at the beginning of the model before the first MoE layer.
62
+ norm_topk_prob (`bool`, *optional*, defaults to `False`):
63
+ Whether to normalize the weights of the routed experts.
64
+ hidden_act (`str` or `function`, *optional*, defaults to `"silu"`):
65
+ The non-linear activation function (function or string).
66
+ max_position_embeddings (`int`, *optional*, defaults to 2048):
67
+ Maximum sequence length the model might ever be used with.
68
+ initializer_range (`float`, *optional*, defaults to 0.02):
69
+ Standard deviation of the truncated_normal_initializer for initializing all weight matrices.
70
+ rms_norm_eps (`float`, *optional*, defaults to 1e-06):
71
+ Epsilon used by the RMS normalization layers.
72
+ use_cache (`bool`, *optional*, defaults to `True`):
73
+ Whether or not the model should return the last key/values attentions. Only relevant if `config.is_decoder=True`.

79
+ Dictionary for scaling RoPE embeddings. Supports `{"type": strategy name, "factor": scaling factor}`.
80
+ attention_bias (`bool`, *optional*, defaults to `False`):
81
+ Whether to use a bias in the self-attention projections.
82
+ attention_dropout (`float`, *optional*, defaults to 0.0):
83
+ Dropout ratio for the attention probabilities.
84
+ routed_scaling_factor (`float`, *optional*, defaults to 1.0):
85
+ Scaling factor for routed experts.
86
+ sliding_window (`int`, *optional*, defaults to 4096):
87
+ Size of the sliding window for attention. If not specified, defaults to `4096`.
88
+ max_window_layers (`int`, *optional*, defaults to 62):
89
+ The number of layers using full attention. The first `max_window_layers` layers will use full attention, while any
90
+ additional layer afterwards will use SWA (Sliding Window Attention).
91
+ layer_types (`list`, *optional*):
92
+ Attention pattern for each layer.
93
+
94

25
+ r"""
26
+ [`DPRConfig`] is the configuration class to store the configuration of a *DPRModel*.
27
+
28
+ This is the configuration class to store the configuration of a [`DPRContextEncoder`], [`DPRQuestionEncoder`], or a
29
+ [`DPRReader`]. It is used to instantiate the components of the DPR model according to the specified arguments,
30
+ defining the model component architectures. Instantiating a configuration with the defaults will yield a similar
31
+ configuration to that of the DPRContextEncoder
32
+ [facebook/dpr-ctx_encoder-single-nq-base](https://huggingface.co/facebook/dpr-ctx_encoder-single-nq-base)
33
+ architecture.
34
+
35
+ This class is a subclass of [`BertConfig`]. Please check the superclass for the documentation of all kwargs.
36
+
37
+ Args:
38
+ vocab_size (`int`, *optional*, defaults to 30522):
39
+ Vocabulary size of the DPR model. Defines the different tokens that can be represented by the *inputs_ids*
40
+ passed to the forward method of [`BertModel`].
41
+ hidden_size (`int`, *optional*, defaults to 768):
42
+ Dimensionality of the encoder layers and the pooler layer.
43
+ num_hidden_layers (`int`, *optional*, defaults to 12):
44
+ Number of hidden layers in the Transformer encoder.
45
+ num_attention_heads (`int`, *optional*, defaults to 12):
46
+ Number of attention heads for each attention layer in the Transformer encoder.
47
+ intermediate_size (`int`, *optional*, defaults to 3072):
48
+ Dimensionality of the "intermediate" (i.e., feed-forward) layer in the Transformer encoder.
49
+ hidden_act (`str` or `function`, *optional*, defaults to `"gelu"`):
50
+ The non-linear activation function (function or string) in the encoder and pooler. If string, `"gelu"`,
51
+ `"relu"`, `"silu"` and `"gelu_new"` are supported.
52
+ hidden_dropout_prob (`float`, *optional*, defaults to 0.1):
53
+ The dropout probability for all fully connected layers in the embeddings, encoder, and pooler.
54
+ attention_probs_dropout_prob (`float`, *optional*, defaults to 0.1):
55
+ The dropout ratio for the attention probabilities.
56
+ max_position_embeddings (`int`, *optional*, defaults to 512):
57
+ The maximum sequence length that this model might ever be used with. Typically set this to something large
58
+ just in case (e.g., 512 or 1024 or 2048).
59
+ type_vocab_size (`int`, *optional*, defaults to 2):
60
+ The vocabulary size of the *token_type_ids* passed into [`BertModel`].
61
+ initializer_range (`float`, *optional*, defaults to 0.02):
62
+ The standard deviation of the truncated_normal_initializer for initializing all weight matrices.
63
+ layer_norm_eps (`float`, *optional*, defaults to 1e-12):
64
+ The epsilon used by the layer normalization layers.
65
+ pad_token_id (`int`, *optional*, defaults to 0):
66
+ Padding token id.
67
+ position_embedding_type (`str`, *optional*, defaults to `"absolute"`):
68
+ Type of position embedding. Choose one of `"absolute"`, `"relative_key"`, `"relative_key_query"`. For
69
+ positional embeddings use `"absolute"`. For more information on `"relative_key"`, please refer to
70
+ [Self-Attention with Relative Position Representations (Shaw et al.)](https://huggingface.co/papers/1803.02155).
71
+ For more information on `"relative_key_query"`, please refer to *Method 4* in [Improve Transformer Models
72
+ with Better Relative Position Embeddings (Huang et al.)](https://huggingface.co/papers/2009.13658).
73
+ projection_dim (`int`, *optional*, defaults to 0):
74
+ Dimension of the projection for the context and question encoders. If it is set to zero (default), then no
75
+ projection is done.
76
+
77
+ Example:
78
+
79
+ ```python
80
+ >>> from transformers import DPRConfig, DPRContextEncoder
81
+
82
+ >>> # Initializing a DPR facebook/dpr-ctx_encoder-single-nq-base style configuration
83
+ >>> configuration = DPRConfig()
84
+
85
+ >>> # Initializing a model (with random weights) from the facebook/dpr-ctx_encoder-single-nq-base style configuration
86
+ >>> model = DPRContextEncoder(configuration)

+ is useful if you want more control over how to convert `input_ids` indices into associated vectors than the
532
+ model's internal embedding lookup matrix.
533
+
534
+ Examples:
535
+
536
+ ```python
537
+ >>> from transformers import DPRReader, DPRReaderTokenizer
538
+
539
+ >>> tokenizer = DPRReaderTokenizer.from_pretrained("facebook/dpr-reader-single-nq-base")
540
+ >>> model = DPRReader.from_pretrained("facebook/dpr-reader-single-nq-base")
541
+ >>> encoded_inputs = tokenizer(
542

544
+ ... texts=["'What Is Love' is a song recorded by the artist Haddaway"],
545
+ ... return_tensors="pt",

547

394
+ This model inherits from [`TFPreTrainedModel`]. Check the superclass documentation for the generic methods the
395
+ library implements for all its model (such as downloading or saving, resizing the input embeddings, pruning heads
396
+ etc.)
397
+
398
+ This model is also a Tensorflow [keras.Model](https://www.tensorflow.org/api_docs/python/tf/keras/Model)
399
+ subclass. Use it as a regular TF 2.0 Keras Model and refer to the TF 2.0 documentation for all matter related to
400
+ general usage and behavior.
401
+
402
+ <Tip>
403
+
404
+ TensorFlow models and layers in `transformers` accept two formats as input:
405
+
406
+ - having all inputs as keyword arguments (like PyTorch models), or
407
+ - having all inputs as a list, tuple or dict in the first positional argument.
408
+
409
+ The reason the second format is supported is that Keras methods prefer this format when passing inputs to models
410
+ and layers. Because of this support, when using methods like `model.fit()` things should "just work" for you - just
411
+ pass your inputs and labels in any format that `model.fit()` supports! If, however, you want to use the second
412
+ format outside of Keras methods like `fit()` and `predict()`, such as when creating your own layers or models with
413
+ the Keras `Functional` API, there are three possibilities you can use to gather all the input Tensors in the first
414
+ positional argument:
415
+
416
+ - a single Tensor with `input_ids` only and nothing else: `model(input_ids)`
417
+ - a list of varying length with one or several input Tensors IN THE ORDER given in the docstring:
418
+ `model([input_ids, attention_mask])` or `model([input_ids, attention_mask, token_type_ids])`
419
+ - a dictionary with one or several input Tensors associated to the input names given in the docstring:
420
+ `model({"input_ids": input_ids, "token_type_ids": token_type_ids})`
421
+
422
+ Note that when creating models and layers with
423
+ [subclassing](https://keras.io/guides/making_new_layers_and_models_via_subclassing/) then you don't need to worry
424
+ about any of this, as you can just pass inputs like you would to any other Python function!
425
+
426
+ </Tip>
427
+
428
+ Parameters:
429
+ config ([`DPRConfig`]): Model configuration class with all the parameters of the model.
430
+ Initializing with a config file does not load the weights associated with the model, only the
431
+ configuration. Check out the [`~TFPreTrainedModel.from_pretrained`] method to load the model weights.

65

66

68

71
+ ```
72
+
73
+ Args:
74
+ questions (`str` or `list[str]`):
75
+ The questions to be encoded. You can specify one question for many passages. In this case, the question
76
+ will be duplicated like `[questions] * n_passages`. Otherwise you have to specify as many questions as in
77
+ `titles` or `texts`.
78
+ titles (`str` or `list[str]`):
79
+ The passages titles to be encoded. This can be a string or a list of strings if there are several passages.
80
+ texts (`str` or `list[str]`):
81
+ The passages texts to be encoded. This can be a string or a list of strings if there are several passages.
82
+ padding (`bool`, `str` or [`~utils.PaddingStrategy`], *optional*, defaults to `False`):
83
+ Activates and controls padding. Accepts the following values:
84
+
85
+ - `True` or `'longest'`: Pad to the longest sequence in the batch (or no padding if only a single sequence
86
+ if provided).
87
+ - `'max_length'`: Pad to a maximum length specified with the argument `max_length` or to the maximum
88
+ acceptable input length for the model if that argument is not provided.
89
+ - `False` or `'do_not_pad'` (default): No padding (i.e., can output a batch with sequences of different
90
+ lengths).
91
+ truncation (`bool`, `str` or [`~tokenization_utils_base.TruncationStrategy`], *optional*, defaults to `False`):
92
+ Activates and controls truncation. Accepts the following values:
93
+
94
+ - `True` or `'longest_first'`: Truncate to a maximum length specified with the argument `max_length` or to
95
+ the maximum acceptable input length for the model if that argument is not provided. This will truncate
96
+ token by token, removing a token from the longest sequence in the pair if a pair of sequences (or a batch
97
+ of pairs) is provided.
98
+ - `'only_first'`: Truncate to a maximum length specified with the argument `max_length` or to the maximum
99
+ acceptable input length for the model if that argument is not provided. This will only truncate the first
100
+ sequence of a pair if a pair of sequences (or a batch of pairs) is provided.
101
+ - `'only_second'`: Truncate to a maximum length specified with the argument `max_length` or to the maximum
102
+ acceptable input length for the model if that argument is not provided. This will only truncate the
103
+ second sequence of a pair if a pair of sequences (or a batch of pairs) is provided.
104
+ - `False` or `'do_not_truncate'` (default): No truncation (i.e., can output batch with sequence lengths
105
+ greater than the model maximum admissible input size).
106
+ max_length (`int`, *optional*):
107
+ Controls the maximum length to use by one of the truncation/padding parameters.
108
+
109
+ If left unset or set to `None`, this will use the predefined model maximum length if a maximum length
110
+ is required by one of the truncation/padding parameters. If the model has no specific maximum input
111
+ length (like XLNet) truncation/padding to a maximum length will be deactivated.
112
+ return_tensors (`str` or [`~utils.TensorType`], *optional*):
113
+ If set, will return tensors instead of list of python integers. Acceptable values are:
114
+
115
+ - `'tf'`: Return TensorFlow `tf.constant` objects.
116
+ - `'pt'`: Return PyTorch `torch.Tensor` objects.
117
+ - `'np'`: Return Numpy `np.ndarray` objects.
118
+ return_attention_mask (`bool`, *optional*):
119
+ Whether or not to return the attention mask. If not set, will return the attention mask according to the
120
+ specific tokenizer's default, defined by the `return_outputs` attribute.
121
+
122
+ [What are attention masks?](../glossary#attention-mask)
123
+
124
+ Returns:
125
+ `dict[str, list[list[int]]]`: A dictionary with the following keys:

128
+ - `attention_mask`: List of indices specifying which tokens should be attended to by the model.

67
+ Return a dictionary with the token ids of the input strings and other information to give to `.decode_best_spans`.
68
+ It converts the strings of a question and different passages (title and text) in a sequence of IDs (integers),
69
+ using the tokenizer and vocabulary. The resulting `input_ids` is a matrix of size `(n_passages, sequence_length)`
70
+ with the format:
71
+
72
+ [CLS] <question token ids> [SEP] <titles ids> [SEP] <texts ids>
73
+
74
+ Args:
75
+ questions (`str` or `list[str]`):
76
+ The questions to be encoded. You can specify one question for many passages. In this case, the question
77
+ will be duplicated like `[questions] * n_passages`. Otherwise you have to specify as many questions as in
78
+ `titles` or `texts`.
79
+ titles (`str` or `list[str]`):
80
+ The passages titles to be encoded. This can be a string or a list of strings if there are several passages.
81
+ texts (`str` or `list[str]`):
82
+ The passages texts to be encoded. This can be a string or a list of strings if there are several passages.
83
+ padding (`bool`, `str` or [`~utils.PaddingStrategy`], *optional*, defaults to `False`):
84
+ Activates and controls padding. Accepts the following values:
85
+
86
+ - `True` or `'longest'`: Pad to the longest sequence in the batch (or no padding if only a single sequence
87
+ if provided).
88
+ - `'max_length'`: Pad to a maximum length specified with the argument `max_length` or to the maximum
89
+ acceptable input length for the model if that argument is not provided.
90
+ - `False` or `'do_not_pad'` (default): No padding (i.e., can output a batch with sequences of different
91
+ lengths).
92
+ truncation (`bool`, `str` or [`~tokenization_utils_base.TruncationStrategy`], *optional*, defaults to `False`):
93
+ Activates and controls truncation. Accepts the following values:
94
+
95
+ - `True` or `'longest_first'`: Truncate to a maximum length specified with the argument `max_length` or to
96
+ the maximum acceptable input length for the model if that argument is not provided. This will truncate
97
+ token by token, removing a token from the longest sequence in the pair if a pair of sequences (or a batch
98
+ of pairs) is provided.
99
+ - `'only_first'`: Truncate to a maximum length specified with the argument `max_length` or to the maximum
100
+ acceptable input length for the model if that argument is not provided. This will only truncate the first
101
+ sequence of a pair if a pair of sequences (or a batch of pairs) is provided.
102
+ - `'only_second'`: Truncate to a maximum length specified with the argument `max_length` or to the maximum
103
+ acceptable input length for the model if that argument is not provided. This will only truncate the
104
+ second sequence of a pair if a pair of sequences (or a batch of pairs) is provided.
105
+ - `False` or `'do_not_truncate'` (default): No truncation (i.e., can output batch with sequence lengths
106
+ greater than the model maximum admissible input size).
107
+ max_length (`int`, *optional*):
108
+ Controls the maximum length to use by one of the truncation/padding parameters.
109
+
110
+ If left unset or set to `None`, this will use the predefined model maximum length if a maximum length
111
+ is required by one of the truncation/padding parameters. If the model has no specific maximum input
112
+ length (like XLNet) truncation/padding to a maximum length will be deactivated.
113
+ return_tensors (`str` or [`~utils.TensorType`], *optional*):
114
+ If set, will return tensors instead of list of python integers. Acceptable values are:
115
+
116
+ - `'tf'`: Return TensorFlow `tf.constant` objects.
117
+ - `'pt'`: Return PyTorch `torch.Tensor` objects.
118
+ - `'np'`: Return Numpy `np.ndarray` objects.
119
+ return_attention_mask (`bool`, *optional*):
120
+ Whether or not to return the attention mask. If not set, will return the attention mask according to the
121
+ specific tokenizer's default, defined by the `return_outputs` attribute.
122
+
123
+ [What are attention masks?](../glossary#attention-mask)
124
+
125
+ Return:
126
+ `dict[str, list[list[int]]]`: A dictionary with the following keys:
127
+
128
+ - `input_ids`: List of token ids to be fed to a model.
129
+ - `attention_mask`: List of indices specifying which tokens should be attended to by the model.
