Getting Started

Installation

1. (Optional) Creating conda environment

   conda create -n vigc python=3.8
   conda activate vigc
   

2. Install mmpretrain

   you can follow the tutorial

3. You may build from source

   git clone https://gitlab.pjlab.org.cn/fdc/mllm/vigc.git
   cd vigc
   pip install -e .
   

Prepare Models

1. obtain vicuna model

   Vicuna is an open-source LLAMA-based LLM that has a performance close to ChatGPT. We currently use the v1.1 version of Vicuna-13B and 7B. If you already have the Vicuna weights with correct version, modify the llm_model in Model Config to the folder that contains your Vicuna weights. Otherwise, you can follow this instruction to get them, remenber that modify the config file too.

2. download pretrain model

   We support two different kinds of pretrain checkpoints to load from: minigpt-4 and instrucblip. You can download them from the table below, more details please visit their original repositories: minigpt-4 and instrucblip.

   Model Type	Checkpoint pretrained with Vicuna 7B	Checkpoint pretrained with Vicuna 13B
   minigpt-4	Download	Download
   instrucblip	Download	Download

   After download the pretrained checkpoints, please modify the pretrained in Model Config to the folder that contains pretrain weights.

3. download fintuned vigc model

   Download the pretrained vigc checkpoints according to fintuned dataset and the Vicuna model you prepared.

   Fintuned Dataset	Checkpoint Fintuned with Vicuna 7B	Checkpoint Fintuned with Vicuna 13B
   LLaVA	Download	Download
   OKVQA	Download	/
   A-OKVQA	Download	/

Launching Demo

To Launch a demo locally, you should:

1. Download the pretrain weight and finetune weight of minigpt-4 and instructblip to local;

2. Update MODEL_CKPT in line 9 of vigc_demo.py；

3. Run python vigc_demo.py and then follow the instruction on the prompts to view in browser. Arguments are as follows:

   • device0: The gpu id of the first model

   • device1: The gpu id of the second model

​ You can also visit to play with VIGC online demo.

Tutorials

   torchrun --nproc_per_node=8 evaluate.py --cfg-path vigc/projects/mini_gpt4_vicuna13b/generate_qa/llava-150k/generate_llava_qa_complex.yaml   # generate complex reasoning data for Llava using MiniGPT4-vicuna13b
   

2. generate QA based on Object365 for Llava

   1. You should first download the finetuned vigc model
   2. Then modify the finetuned in corresponding Inference Config to the path to the checkpoint file.
