Getting Started

Installation

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.git
cd MiniGPT-4
conda env create -f environment.yml
conda activate minigptv

2. Prepare the pretrained LLM weights

MiniGPT-v2 is based on Llama2 Chat 7B. For MiniGPT-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 variable llama_model in the model config file to the LLM weight path.

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

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

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

3. Prepare the pretrained model checkpoints

Download the pretrained model checkpoints

For MiniGPT-v2, set the path to the pretrained checkpoint in the evaluation config file in eval_configs/minigptv2_eval.yaml at Line 8.

For MiniGPT-4, set the path to the pretrained checkpoint in the evaluation config file in eval_configs/minigpt4_eval.yaml at Line 8 for Vicuna version or eval_configs/minigpt4_llama2_eval.yaml for LLama2 version.

Launching Demo Locally

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 model in 16 bit by setting low_resource to False 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 on Colab
