+# mPLUG-Owl3
+
+## Introduction
+mPLUG-Owl3 is a state-of-the-art multi-modal large language model designed to tackle the challenges of long image sequence understanding. We propose Hyper Attention, which boosts the speed of long visual sequence understanding in multimodal large language models by sixfold, allowing for processing of visual sequences that are eight times longer. Meanwhile, we maintain excellent performance on single-image, multi-image, and video tasks.
+
+Github: [mPLUG-Owl](https://github.com/X-PLUG/mPLUG-Owl)
+
+## What's new
+```mPLUG-Owl3-7B-241101``` is a improved version of ```mPLUG-Owl3-7B-240728```.
+
+### Fused Hyper Attention
+mPLUG-Owl3 requires separate calculations for cross-attention and self-attention, and fuses the outputs of both through a adaptive gate. Now, we use a unified operation that only requires computing attention once.
+
+### New template for media inputs
+We now use the following format to represent the splited high-resolution images. In addition, we can now enable image splitting when the input consists of multiple images to achieve further performance benefits, which the old version of mPLUG-Owl3 was not trained to handle with this combination.
+```
+<|start_cut|>2*3
+<|image|> <|image|> <|image|>
+<|image|> <|image|> <|image|>
+<|image|><|end_cut|>
+```
+And we use the following format to represent video.
+```
+<|start_video_frame|><|image|><|image|><|image|><|end_video_frame|>
+```
+
+
+### Adjusted media_offset
+Previously, media_offset recorded the range of images each token could see. During training, since the images from multiple samples are concatenated together along the batch dimension, media_offset needed to be carefully modified, otherwise it would point to the wrong image. To prevent this, media_offset is now a List[List[int]], representing the position of each image in a sample within the batch in the original sequence. This design also makes the computation of the cross-attention mask and MI-Rope more efficient and convenient.
+
+**All of these changes are well handled by the processor, and you don't need to change the original way of calling it.**

+## Quickstart
+
+Load the mPLUG-Owl3. We now only support attn_implementation in ```['sdpa', 'flash_attention_2']```.
+```Python
+import torch
+from modelscope import AutoConfig, AutoModel
+model_path = 'iic/mPLUG-Owl3-2B-241101'
+config = AutoConfig.from_pretrained(model_path, trust_remote_code=True)
+print(config)
+model = AutoModel.from_pretrained(model_path, attn_implementation='flash_attention_2', torch_dtype=torch.bfloat16, trust_remote_code=True)
+_ = model.eval().cuda()
+device = "cuda"
+```
+
+Chat with images.
+```Python
+from PIL import Image
+
+from modelscope import AutoTokenizer
+from decord import VideoReader, cpu 
+tokenizer = AutoTokenizer.from_pretrained(model_path)
+processor = model.init_processor(tokenizer)
+
+image = Image.new('RGB', (500, 500), color='red')
+
+messages = [
+    {"role": "user", "content": """<|image|>
+Describe this image."""},
+    {"role": "assistant", "content": ""}

+```
+
+### Save memory by setting device_map
+When you have more than one GPUs, you can set the ```device_map='auto'``` to split the mPLUG-Owl3 into multiple GPUs. However, it will slowdown the inference speed.
+
+```python
+model = AutoModel.from_pretrained(model_path, attn_implementation='flash_attention_2', device_map="auto", torch_dtype=torch.bfloat16, trust_remote_code=True)
+_ = model.eval()
+first_layer_name = list(model.hf_device_map.keys())[0]
+device = model.hf_device_map[first_layer_name]

+    This is the configuration class to store the configuration of a [`Qwen2Model`]. It is used to instantiate a

+    Args:
+        vocab_size (`int`, *optional*, defaults to 151936):
+            Vocabulary size of the Qwen2 model. Defines the number of different tokens that can be represented by the
+            `inputs_ids` passed when calling [`Qwen2Model`]
+        hidden_size (`int`, *optional*, defaults to 4096):
+            Dimension of the hidden representations.
+        intermediate_size (`int`, *optional*, defaults to 22016):
+            Dimension of the MLP representations.
+        num_hidden_layers (`int`, *optional*, defaults to 32):
+            Number of hidden layers in the Transformer encoder.
+        num_attention_heads (`int`, *optional*, defaults to 32):
+            Number of attention heads for each attention layer in the Transformer encoder.
+        num_key_value_heads (`int`, *optional*, defaults to 32):
+            This is the number of key_value heads that should be used to implement Grouped Query Attention. If
+            `num_key_value_heads=num_attention_heads`, the model will use Multi Head Attention (MHA), if
+            `num_key_value_heads=1` the model will use Multi Query Attention (MQA) otherwise GQA is used. 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. For more details checkout [this
+            paper](https://arxiv.org/pdf/2305.13245.pdf). If it is not specified, will default to `32`.

+            The non-linear activation function (function or string) in the decoder.
+        max_position_embeddings (`int`, *optional*, defaults to 32768):
+            The maximum sequence length that this model might ever be used with.
+        initializer_range (`float`, *optional*, defaults to 0.02):
+            The standard deviation of the truncated_normal_initializer for initializing all weight matrices.
+        rms_norm_eps (`float`, *optional*, defaults to 1e-06):
+            The epsilon used by the rms normalization layers.
+        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`.
+        tie_word_embeddings (`bool`, *optional*, defaults to `False`):
+            Whether the model's input and output word embeddings should be tied.
+        rope_theta (`float`, *optional*, defaults to 10000.0):
+            The base period of the RoPE embeddings.
+        use_sliding_window (`bool`, *optional*, defaults to `False`):
+            Whether to use sliding window attention.
+        sliding_window (`int`, *optional*, defaults to 4096):
+            Sliding window attention (SWA) window size. If not specified, will default to `4096`.
+        max_window_layers (`int`, *optional*, defaults to 28):
+            The number of layers that use SWA (Sliding Window Attention). The bottom layers use SWA while the top use full attention.

+

+        attention_mask (`torch.Tensor` 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**,

+
+            If `past_key_values` is used, optionally only the last `decoder_input_ids` have to be input (see
+            `past_key_values`).
+
+            If you want to change padding behavior, you should read [`modeling_opt._prepare_decoder_attention_mask`]
+            and modify to your needs. See diagram 1 in [the paper](https://arxiv.org/abs/1910.13461) for more

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

+            Pre-computed hidden-states (key and values in the self-attention blocks and in the cross-attention
+            blocks) that can be used to speed up sequential decoding. This typically consists in the `past_key_values`
+            returned by the model at a previous stage of decoding, when `use_cache=True` or `config.use_cache=True`.

+            shape `(batch_size, num_heads, sequence_length, embed_size_per_head)`). This is also known as the legacy
+            cache format.
+
+            The model will output the same cache format that is fed as input. If no `past_key_values` are passed, the
+            legacy cache format will be returned.
+
+            If `past_key_values` are used, the user can optionally input only the last `input_ids` (those that don't
+            have their past key value states given to this model) of shape `(batch_size, 1)` instead of all `input_ids`
+            of shape `(batch_size, sequence_length)`.
+        inputs_embeds (`torch.FloatTensor` of shape `(batch_size, sequence_length, hidden_size)`, *optional*):
+            Optionally, instead of passing `input_ids` you can choose to directly pass an embedded representation. This
+            is useful if you want more control over how to convert `input_ids` indices into associated vectors than the
+            model's internal embedding lookup matrix.
+        use_cache (`bool`, *optional*):
+            If set to `True`, `past_key_values` key value states are returned and can be used to speed up decoding (see
