[Oct.31 2023] We release the evaluation code of our MiniGPT-v2.

[Oct.24 2023] We release the finetuning code of our MiniGPT-v2.

[Oct.13 2023] Breaking! We release the first major update with our MiniGPT-v2

[Aug.28 2023] We now provide a llama 2 version of MiniGPT-4

1. Prepare the code and the environment

Git clone our repository, creating a python environment and activate it via the following command

git clone https://github.com/Vision-CAIR/MiniGPT-4.gitcd MiniGPT-4conda env create -f environment.ymlconda activate minigptv

2. Prepare the pretrained LLM weights

MiniGPT-v2 is based on Llama2 Chat 7B. ForMiniGPT-4, we have both Vicuna V0 and Llama 2 version.Download the corresponding LLM weights from the following huggingface space via clone the repository using git-lfs.

Then, set the variablellama_model in the model config file to the LLM weight path.

• For MiniGPT-v2, set the LLM pathhere at Line 14.

• For MiniGPT-4 (Llama2), set the LLM pathhere at Line 15.

• For MiniGPT-4 (Vicuna), set the LLM pathhere at Line 18

3. Prepare the pretrained model checkpoints

Download the pretrained model checkpoints

ForMiniGPT-v2, set the path to the pretrained checkpoint in the evaluation config fileineval_configs/minigptv2_eval.yaml at Line 8.

ForMiniGPT-4, set the path to the pretrained checkpoint in the evaluation config fileineval_configs/minigpt4_eval.yaml at Line 8 for Vicuna version oreval_configs/minigpt4_llama2_eval.yaml for LLama2 version.

For MiniGPT-v2, run

python demo_v2.py --cfg-path eval_configs/minigptv2_eval.yaml  --gpu-id 0

For MiniGPT-4 (Vicuna version), run

python demo.py --cfg-path eval_configs/minigpt4_eval.yaml  --gpu-id 0

For MiniGPT-4 (Llama2 version), run

python demo.py --cfg-path eval_configs/minigpt4_llama2_eval.yaml  --gpu-id 0

To save GPU memory, LLMs loads as 8 bit by default, with a beam search width of 1.This configuration requires about 23G GPU memory for 13B LLM and 11.5G GPU memory for 7B LLM.For more powerful GPUs, you can run the modelin 16 bit by settinglow_resource toFalse in the relevant config file:

• MiniGPT-v2:minigptv2_eval.yaml
• MiniGPT-4 (Llama2):minigpt4_llama2_eval.yaml
• MiniGPT-4 (Vicuna):minigpt4_eval.yaml

Thanks@WangRongsheng, you can also run MiniGPT-4 onColab

• BLIP2 The model architecture of MiniGPT-4 follows BLIP-2. Don't forget to check this great open-source work if you don't know it before!
• Lavis This repository is built upon Lavis!
• Vicuna The fantastic language ability of Vicuna with only 13B parameters is just amazing. And it is open-source!
• LLaMA The strong open-sourced LLaMA 2 language model.
