# MM Grounding DINO [MM Grounding DINO](https://huggingface.co/papers/2401.02361) model was proposed in [An Open and Comprehensive Pipeline for Unified Object Grounding and Detection](https://huggingface.co/papers/2401.02361) by Xiangyu Zhao, Yicheng Chen, Shilin Xu, Xiangtai Li, Xinjiang Wang, Yining Li, Haian Huang>. MM Grounding DINO improves upon the [Grounding DINO](https://huggingface.co/docs/transformers/model_doc/grounding-dino) by improving the contrastive class head and removing the parameter sharing in the decoder, improving zero-shot detection performance on both COCO (50.6(+2.2) AP) and LVIS (31.9(+11.8) val AP and 41.4(+12.6) minival AP).

This model inherits from [PreTrainedModel](/docs/transformers/v5.8.0/en/main_classes/model#transformers.PreTrainedModel). Check the superclass documentation for the generic methods the library implements for all its model (such as downloading or saving, resizing the input embeddings, pruning heads etc.) This model is also a PyTorch [torch.nn.Module](https://pytorch.org/docs/stable/nn.html#torch.nn.Module) subclass. Use it as a regular PyTorch Module and refer to the PyTorch documentation for all matter related to general usage and behavior. forwardtransformers.MMGroundingDinoForObjectDetection.forwardhttps://github.com/huggingface/transformers/blob/v5.8.0/src/transformers/models/mm_grounding_dino/modeling_mm_grounding_dino.py#L2401[{"name": "pixel_values", "val": ": FloatTensor"}, {"name": "input_ids", "val": ": LongTensor"}, {"name": "token_type_ids", "val": ": torch.LongTensor | None = None"}, {"name": "attention_mask", "val": ": torch.LongTensor | None = None"}, {"name": "pixel_mask", "val": ": torch.BoolTensor | None = None"}, {"name": "encoder_outputs", "val": ": transformers.models.mm_grounding_dino.modeling_mm_grounding_dino.MMGroundingDinoEncoderOutput | tuple | None = None"}, {"name": "output_attentions", "val": ": bool | None = None"}, {"name": "output_hidden_states", "val": ": bool | None = None"}, {"name": "return_dict", "val": ": bool | None = None"}, {"name": "labels", "val": ": list[dict[str, torch.LongTensor | torch.FloatTensor]] | None = None"}, {"name": "**kwargs", "val": ""}]- **pixel_values** (`torch.FloatTensor` of shape `(batch_size, num_channels, image_size, image_size)`) -- The tensors corresponding to the input images. Pixel values can be obtained using [GroundingDinoImageProcessor](/docs/transformers/v5.8.0/en/model_doc/grounding-dino#transformers.GroundingDinoImageProcessor). See `GroundingDinoImageProcessor.__call__()` for details ([GroundingDinoProcessor](/docs/transformers/v5.8.0/en/model_doc/grounding-dino#transformers.GroundingDinoProcessor) uses [GroundingDinoImageProcessor](/docs/transformers/v5.8.0/en/model_doc/grounding-dino#transformers.GroundingDinoImageProcessor) for processing images). - **input_ids** (`torch.LongTensor` of shape `(batch_size, text_sequence_length)`) -- Indices of input sequence tokens in the vocabulary. Padding will be ignored by default should you provide it. Indices can be obtained using [AutoTokenizer](/docs/transformers/v5.8.0/en/model_doc/auto#transformers.AutoTokenizer). See [BertTokenizer.__call__()](/docs/transformers/v5.8.0/en/internal/tokenization_utils#transformers.PreTrainedTokenizerBase.__call__) for details. - **token_type_ids** (`torch.LongTensor` of shape `(batch_size, text_sequence_length)`, *optional*) -- Segment token indices to indicate first and second portions of the inputs. Indices are selected in `[0, 1]`: 0 corresponds to a `sentence A` token, 1 corresponds to a `sentence B` token [What are token type IDs?](../glossary#token-type-ids) - **attention_mask** (`torch.LongTensor` of shape `(batch_size, sequence_length)`, *optional*) -- Mask to avoid performing attention on padding token indices. Mask values selected in `[0, 1]`: - 1 for tokens that are **not masked**, - 0 for tokens that are **masked**. [What are attention masks?](../glossary#attention-mask) - **pixel_mask** (`torch.BoolTensor` of shape `(batch_size, height, width)`, *optional*) -- Mask to avoid performing attention on padding pixel values. Mask values selected in `[0, 1]`: - 1 for pixels that are real (i.e. **not masked**), - 0 for pixels that are padding (i.e. **masked**). [What are attention masks?](../glossary#attention-mask) - **encoder_outputs** (`Union[~models.mm_grounding_dino.modeling_mm_grounding_dino.MMGroundingDinoEncoderOutput, tuple]`, *optional*) -- Tuple consists of (`last_hidden_state`, *optional*: `hidden_states`, *optional*: `attentions`) `last_hidden_state` of shape `(batch_size, sequence_length, hidden_size)`, *optional*) is a sequence of hidden-states at the output of the last layer of the encoder. Used in the cross-attention of the decoder. - **output_attentions** (`bool`, *optional*) -- Whether or not to return the attentions tensors of all attention layers. See `attentions` under returned tensors for more detail. - **output_hidden_states** (`bool`, *optional*) -- Whether or not to return the hidden states of all layers. See `hidden_states` under returned tensors for more detail. - **return_dict** (`bool`, *optional*) -- Whether or not to return a [ModelOutput](/docs/transformers/v5.8.0/en/main_classes/output#transformers.utils.ModelOutput) instead of a plain tuple. - **labels** (`list[Dict]` of len `(batch_size,)`, *optional*) -- Labels for computing the bipartite matching loss. List of dicts, each dictionary containing at least the following 2 keys: 'class_labels' and 'boxes' (the class labels and bounding boxes of an image in the batch respectively). The class labels themselves should be a `torch.LongTensor` of len `(number of bounding boxes in the image,)` and the boxes a `torch.FloatTensor` of shape `(number of bounding boxes in the image, 4)`.0 The [MMGroundingDinoForObjectDetection](/docs/transformers/v5.8.0/en/model_doc/mm-grounding-dino#transformers.MMGroundingDinoForObjectDetection) forward method, overrides the `__call__` special method. Although the recipe for forward pass needs to be defined within this function, one should call the `Module` instance afterwards instead of this since the former takes care of running the pre and post processing steps while the latter silently ignores them.

Initializing with a config file does not load the weights associated with the model, only the configuration.
