Updates π
[2024/1/15]π₯ We released the evaluation code.
[2023/12/29]π₯ We released the training code and Osprey-724K dataset.
[2023/12/18]π₯ We released the code, osprey-7b model and online demo for Osprey.
What is Osprey π
Osprey is a mask-text instruction tuning approach that extends MLLMs by incorporating pixel-wise mask regions into language instructions, enabling fine-grained visual understanding. Based on input mask region, Osprey generate the semantic descriptions including short description and detailed description.
Our Osprey can seamlessly integrate with SAM in point-prompt, box-prompt and segmentation everything modes to generate the semantics associated with specific parts or objects.

Offline demo
π» requirments: For this demo, it needs about 17GB
GPU memory for Osprey(15GB) and SAM(2GB).
- First install Gradio-Osprey-Demo.
- Install Segment Anything.
pip install git+https://github.com/facebookresearch/segment-anything.git
-
Download ViT-B SAM model to checkpoints.
-
Run
app.py
.
cd demo
python app.py --model checkpoint/osprey_7b
Install π οΈ
- Clone this repository and navigate to Osprey folder
git clone https://github.com/CircleRadon/Osprey.git
cd Osprey
- Install packages
conda create -n osprey python=3.10 -y
conda activate osprey
pip install --upgrade pip # enable PEP 660 support
pip install -e .
- Install additional packages for training cases
pip install -e ".[train]"
pip install flash-attn --no-build-isolation
Dataset π
The all datasets for training can be found in Dataset preparation.
Osprey-724K: π€Hugging Face
Osprey-724K
is an instruction dataset with mask-text pairs, containing around 724K GPT-generated multimodal dialogues to encourage MLLMs for fine-grained pixel-level image understanding. It contains object-level, part-level and additional instruction samples for robustness and flexibility.
Training π
-
Stage1: Image-Text Alignment Pre-training
- The pretrained projector weights for Convnext-large-CLIP can be found in projector weights.
-
Stage2: Mask-Text Alignment Pre-training
- Download vicuna-7b-v1.5.
- Download projector weights trained in stage1: projector weights.
- Set
model_name_or_path
instage2.sh
to the path ofvicuna-7b-v1.5
. - Set
pretrain_mm_mlp_adapter
instage2.sh
to the path ofmm_projector
. - Set
vision_tower
instage2.sh
to the path of Convnext-large-CLIP-model. - Run
sh scripts/stage2.sh
.
-
Stage3: End-to-End Fine-tuning
- Set
model_name_or_path
instage2.sh
to the path ofstage2 checkpoint
. - Set
vision_tower
instage2.sh
to the path of Convnext-large-CLIP-model. - Run
sh scripts/stage3.sh
.
- Set
Checkpoints π€
Then change the "mm_vision_tower" in config.json
of Osprey-7b model to the path of Convnext-large-CLIP-model
.
Evaluation π
See evaluation for details.
TODO List π
- Release the checkpoints, inference codes and demo.
- Release the dataset and training scripts.
- Release the evaluation code.
- Release the code for data generation pipeline.
Acknowledgement π
- LLaVA-v1.5: the codebase we built upon.
- SAM: the demo uses the segmentation result from SAM as the input of Osprey.
