minigpt4.cpp

Inference of MiniGPT4 in pure C/C++.

Description

The main goal of minigpt4.cpp is to run minigpt4 using 4-bit quantization with using the ggml library.

Demo

Usage

1. Clone repo

Requirements: git

git clone --recursive https://github.com/Maknee/minigpt4.cpp
cd minigpt4.cpp

2. Getting the library

Option 1: Download precompiled binary

Windows / Linux / MacOS

Go to Releases and extract minigpt4 library file into the repository directory.

Option 2: Build library manually

Windows

Requirements: CMake, Visual Studio and Git

cmake .
cmake --build . --config Release

bin\Release\minigpt4.dll should be generated

Linux

Requirements: CMake (Ubuntu: sudo apt install cmake)

cmake .
cmake --build . --config Release

minigpt4.so should be generated

MacOS

Requirements: CMake (MacOS: brew install cmake)

cmake .
cmake --build . --config Release

minigpt4.dylib should be generated

Note: If you build with opencv (allowing features such as loading and preprocessing image within the library itself), set MINIGPT4_BUILD_WITH_OPENCV to ON in CMakeLists.txt or build with -DMINIGPT4_BUILD_WITH_OPENCV=ON as a parameter to the cmake cli.

3. Obtaining the model

Option 1: Download pre-quantized MiniGPT4 model

Pre-quantized models are available on Hugging Face ~ 7B or 13B.

Recommended for reliable results, but slow inference speed: minigpt4-13B-f16.bin

Option 2: Convert and quantize PyTorch model

Requirements: Python 3.x and PyTorch.

Clone the MiniGPT-4 repository and perform the setup

cd minigpt4
git clone https://github.com/Vision-CAIR/MiniGPT-4.git
cd MiniGPT-4
conda env create -f environment.yml
conda activate minigpt4

Download the pretrained checkpoint in the MiniGPT-4 repository under Checkpoint Aligned with Vicuna 7B or Checkpoint Aligned with Vicuna 13B or download them from Huggingface link for 7B or 13B

Convert the model weights into ggml format

Windows

7B model

cd minigpt4
python convert.py C:\pretrained_minigpt4_7b.pth --ftype=f16

13B model

cd minigpt4
python convert.py C:\pretrained_minigpt4.pth --ftype=f16

Linux / MacOS

7B model

python convert.py ~/Downloads/pretrained_minigpt4_7b.pth --outtype f16

13B model

python convert.py ~/Downloads/pretrained_minigpt4.pth --outtype f16

minigpt4-7B-f16.bin or minigpt4-13B-f16.bin should be generated

4. Obtaining the vicuna model

Option 1: Download pre-quantized vicuna-v0 model

Pre-quantized models are available on Hugging Face

Recommended for reliable results and decent inference speed: ggml-vicuna-13B-v0-q5_k.bin

Option 2: Convert and quantize vicuna-v0 model

Requirements: Python 3.x and PyTorch.

Follow the guide from the MiniGPT4 to obtain the vicuna-v0 model.

Then, clone llama.cpp

git clone https://github.com/ggerganov/llama.cpp
cd llama.cpp
cmake .
cmake --build . --config Release

Convert the model to ggml

python convert.py <path-to-model>

Quantize the model

python quanitize <path-to-model> <output-model> Q4_1

5. Running

Test if minigpt4 works by calling the following, replacing minigpt4-13B-f16.bin and ggml-vicuna-13B-v0-q5_k.bin with your respective models

cd minigpt4
python minigpt4_library.py minigpt4-13B-f16.bin ggml-vicuna-13B-v0-q5_k.bin

Webui

Install the requirements for the webui

pip install -r requirements.txt

Then, run the webui, replacing minigpt4-13B-f16.bin and ggml-vicuna-13B-v0-q5_k.bin with your respective models

python webui.py minigpt4-13B-f16.bin ggml-vicuna-13B-v0-q5_k.bin

The output should contain something like the following:

Running on local URL:  http://127.0.0.1:7860

To create a public link, set `share=True` in `launch()`.

Go to http://127.0.0.1:7860 in your browser and you should be able to interact with the webui.
