🤖 Multi-modal GPT

Train a multi-modal chatbot with visual and language instructions!

Based on the open-source multi-modal model OpenFlamingo, we create various visual instruction data with open datasets, including VQA, Image Captioning, Visual Reasoning, Text OCR, and Visual Dialogue. Additionally, we also train the language model component of OpenFlamingo using only language-only instruction data.

The joint training of visual and language instructions effectively improves the performance of the model! For more details please refer to our technical report.

Welcome to join us!

Features

• Support various vision and language instruction data
• Parameter efficient fine-tuning with LoRA
• Tuning vision and language at the same time, complement each other

Installation

To install the package in an existing environment, run

git clone https://github.com/open-mmlab/Multimodal-GPT.git
cd Multimodal-GPT
pip install -r requirements.txt
pip install -v -e .

or create a new conda environment

conda env create -f environment.yml

Launch Demo Locally

1. Download the pre-trained weights.

   Use this script for converting LLaMA weights to Hugging Face format.

   Download the OpenFlamingo pre-trained model from openflamingo/OpenFlamingo-9B.

   Download our LoRA Weight from here.

   Then place these models in checkpoints folders like this:

   checkpoints
   ├── llama-7b_hf
   │   ├── config.json
   │   ├── pytorch_model-00001-of-00002.bin
   │   ├── ......
   │   └── tokenizer.model
   ├── OpenFlamingo-9B
   │   └──checkpoint.pt
   ├──mmgpt-lora-v0-release.pt
   
   

2. launch the gradio demo

   python app.py

Fine-tuning

Prepare datasets

1. A-OKVQA

   Download annotation from this link and unzip to data/aokvqa/annotations.

   It also requires images from coco dataset which can be downloaded from here.

2. COCO Caption

   Download from this link and unzip to data/coco.

   It also requires images from coco dataset which can be downloaded from here.

3. OCR VQA

   Download from this link and place in data/OCR_VQA/.

4. LlaVA

   Download from liuhaotian/LLaVA-Instruct-150K and place in data/llava/.

   It also requires images from coco dataset which can be downloaded from here.

5. Mini-GPT4

   Download from Vision-CAIR/cc_sbu_align and place in data/cc_sbu_align/.

6. Dolly 15k

   Download from databricks/databricks-dolly-15k and place it in data/dolly/databricks-dolly-15k.jsonl.

7. Alpaca GPT4

   Download it from this link and place it in data/alpaca_gpt4/alpaca_gpt4_data.json.

You can also customize the data path in the configs/dataset_config.py.

8. Baize

   Download it from this link and place it in data/baize/quora_chat_data.json.
