News

[Jan.03 2024] Welcome to Hugging Face online demo to try out our models (for Stage-3)!

[Dec.28 2023] Breaking! We release the code of our TinyGPT-V.

TinyGPT-V Traning Process

TinyGPT-V Model Structure

TinyGPT-V Results

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/DLYuanGod/TinyGPT-V.git
cd TinyGPT-V
conda env create -f environment.yml
conda activate tinygptv

2. Prepare the pretrained LLM weights

TinyGPT-V is based on Phi-2. Download the corresponding LLM weights from the following huggingface space via clone the repository using git-lfs.

Phi-2 2.7B: Download

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

• For MiniGPT-v2, set the LLM path here at Line 14 and here at Line 18.

3. Prepare the pretrained model checkpoints

Download the pretrained model checkpoints

For TinyGPT-V, set the path to the pretrained checkpoint in the evaluation config file in tinygptv_stage1_2_3_eval.yaml at Line 8 for Stage 1, 2 and 3 version or tinygptv_stage4_eval.yaml for Stage 4 version.

4. Update the Phi-2 Modeling for transformers lib.

Linux system:

cp modeling_phi.py /root/miniconda3/envs/tinygptv/lib/python3.9/site-packages/transformers/models/phi/

Windows system

Find your conda yourself: conda_sit/envs/tinygptv/lib/python3.9/site-packages/transformers/models/phi/ Replace modeling_phi.py in that directory with the one in TinyGPT-V/modeling_phi.py.

Launching Demo Locally

For Stage 4, run

python demo_v2.py --cfg-path eval_configs/tinygptv_stage4_eval.yaml  --gpu-id 0

For Stage 1, 2 and 3, run

python demo.py --cfg-path eval_configs/tinygptv_stage1_2_3_eval.yaml  --gpu-id 0

To perfer more powerful model, LLMs loads as 16 bit by default. This configuration requires about 8G GPU memory. To more save GPU memory, you can run the model in 8 bit below 8G device by setting low_resource to True in the relevant config file:

• Stage 4 tinygptv_stage4_eval.yaml

• Stage 1, 2 and 3 tinygptv_stage1_2_3_eval.yaml

-Note: Stage 4 is currently a test version as it utilizes partial data for traing. Please use Stage 3 for the demo.

Training

First you need to adjust all the updated weights in the LLM to be calculated with full precision:Here. Remove the comments from the following lines:

                layer.self_attn.q_layernorm.weight.data = layer.self_attn.q_layernorm.weight.data.float()
                layer.self_attn.k_layernorm.weight.data = layer.self_attn.k_layernorm.weight.data.float()
                layer.post_layernorm.weight.data = layer.post_layernorm.weight.data.float()
                layer.input_layernorm.weight.data = layer.input_layernorm.weight.data.float()

                # Perform a similar operation for the bias item
                if layer.self_attn.q_layernorm.bias is not None:
                    layer.self_attn.q_layernorm.bias.data = layer.self_attn.q_layernorm.bias.data.float()
                if layer.self_attn.k_layernorm.bias is not None:
                    layer.self_attn.k_layernorm.bias.data = layer.self_attn.k_layernorm.bias.data.float()
                if layer.input_layernorm.bias is not None:
                    layer.input_layernorm.bias.data = layer.input_layernorm.bias.data.float()


            llama_model.model.model.final_layernorm.weight.requires_grad = True
            llama_model.model.model.final_layernorm.weight.data = llama_model.model.model.final_layernorm.weight.data.float()
            if llama_model.model.model.final_layernorm.bias is not None:
                llama_model.model.model.final_layernorm.bias.data = llama_model.model.model.final_layernorm.bias.float()

Stage 1 and 2:

• Datasets: first stage dataset preparation instruction

• Then run:

torchrun --nproc-per-node NUM_GPU train.py --cfg-path train_configs/tinygptv_stage1.yaml

You need to execute the above code 17 times to complete the first stage of training.

• Then run:

torchrun --nproc-per-node NUM_GPU train.py --cfg-path train_configs/tinygptv_stage2.yaml

Stage 3:

• Datasets: stage 3 dataset preparation instruction

• Then run:

torchrun --nproc-per-node NUM_GPU train.py --cfg-path train_configs/tinygptv_stage3.yaml

Stage 4:

• Datasets: stage 4 dataset preparation instruction Please prepare all datasets except COCO captions and OCR-VQA.

• Then run:

torchrun --nproc-per-node NUM_GPU train.py --cfg-path train_configs/tinygptv_stage4.yaml
