Team: Yixuan Su^*, Tian Lan^*, Huayang Li^*, Jialu Xu, Yan Wang, and Deng Cai^* (Major contributors^*)

Online Demo Demonstration:

Below, we demonstrate some examples of our online demo. For more generated examples of PandaGPT, please refer to our webpage or our paper.

(1) In this example, PandaGPT takes an input image and reasons over the user's input.

(2) In this example, PandaGPT takes the joint input from two modalities, i.e. (1) an <b>image</b> 👀 of car and (2) an <b>audio</b>👂 of thunderstorm.

PandaGPT is the first foundation model capable of instruction-following data across six modalities, without the need of explicit supervision. It demonstrates a diverse set of multimodal capabilities such as complex understanding/reasoning, knowledge-grounded description, and multi-turn conversation.

PandaGPT is a general-purpose instruction-following model that can both <b>see 👀</b> and <b>hear👂</b>. Our pilot experiments show that PandaGPT can perform complex tasks such as detailed image description generation, writing stories inspired by videos, and answering questions about audios. More Interestingly, PandaGPT can take multimodal inputs simultaneously and compose their semantics naturally. For example, PandaGPT can connect how objects look in a photo and how they sound in an audio.

2. Running PandaGPT Demo: <a href='#all_catelogue'>[Back to Top]</a>

2.1. Environment Installation:

To install the required environment, please run

pip install -r requirements.txt

Then install the Pytorch package with the correct cuda version, for example

pip install torch==1.13.1+cu117 -f https://download.pytorch.org/whl/torch/

2.2. Prepare ImageBind Checkpoint:

You can download the pre-trained ImageBind model using this link. After downloading, put the downloaded file (imagebind_huge.pth) in [./pretrained_ckpt/imagebind_ckpt/] directory.

2.3. Prepare Vicuna Checkpoint:

To prepare the pre-trained Vicuna model, please follow the instructions provided [here].

2.4. Prepare Delta Weights of PandaGPT:

We release the delta weights of PandaGPT trained with different strategies in the table above. After downloading, put the downloaded 7B/13B delta weights file (pytorch_model.pt) in the ./pretrained_ckpt/pandagpt_ckpt/7b/ or ./pretrained_ckpt/pandagpt_ckpt/13b/ directory. In our online demo, we use the openllmplayground/pandagpt_7b_max_len_1024 as our default model due to the limitation of computation resource. Better results are expected if switching to openllmplayground/pandagpt_13b_max_len_400.

2.5. Deploying Demo:

Upon completion of previous steps, you can run the demo locally as

cd ./code/
CUDA_VISIBLE_DEVICES=0 python web_demo.py

If you running into sample_rate problem, please git install pytorchvideo from the source as

git clone https://github.com/facebookresearch/pytorchvideo
cd pytorchvideo
pip install --editable ./

3. Train Your Own PandaGPT: <a href='#all_catelogue'>[Back to Top]</a>

Prerequisites: Before training the model, making sure the environment is properly installed and the checkpoints of ImageBind and Vicuna are downloaded. You can refer to here for more information.

3.1. Data Preparation:

Declaimer: To ensure the reproducibility of our results, we have released our training dataset. The dataset must be used for research purpose only. The use of the dataset must comply with the licenses from original sources, i.e. LLaVA and MiniGPT-4. These datasets may be taken down when requested by the original authors.

After downloading, put the downloaded file and unzip them under the ./data/ directory.

**** The directory should look like:

.
└── ./data/ 
     ├── pandagpt4_visual_instruction_data.json
     └── /images/
         ├── 000000426538.jpg
         ├── 000000306060.jpg
         └── ...
          

3.2 Training Configurations:

The table below show the training hyperparameters used in our experiments. The hyperparameters are selected based on the constrain of our computational resources, i.e. 8 x A100 (40G) GPUs.

3.3. Training PandaGPT:

To train PandaGPT, please run the following commands:

cd ./code/scripts/
chmod +x train.sh
cd ..
./scripts/train.sh

The key arguments of the training script are as follows:

• --data_path: The data path for the json file pandagpt4_visual_instruction_data.json.
• --image_root_path: The root path for the downloaded images.
• --imagebind_ckpt_path: The path where saves the ImageBind checkpoint imagebind_huge.pth.
• --vicuna_ckpt_path: The directory that saves the pre-trained Vicuna checkpoints.
• --max_tgt_len: The maximum sequence length of training instances.
• --save_path: The directory which saves the trained delta weights. This directory will be automatically created.

Note that the epoch number can be set in the epochs argument at ./code/config/openllama_peft.yaml file. The train_micro_batch_size_per_gpu and gradient_accumulation_steps arguments in ./code/dsconfig/openllama_peft_stage_1.json should be set as 2 and 4 for 7B model, and set as 1 and 8 for 13B model.

Usage and License Notices:

PandaGPT is intended and licensed for research use only. The dataset is CC BY NC 4.0 (allowing only non-commercial use) and models trained using the dataset should not be used outside of research purposes. The delta weights are also CC BY NC 4.0 (allowing only non-commercial use).
