## Brief Introduction

NExt-GPT is built on top of existing pre-trained LLM, multimodal encoder and SoTA diffusion models, with sufficient end-to-end instruction tuning.

- **Multimodal Encoding Stage.** Leveraging established encoders to encode inputs in various modalities, where these representations are projected into language-like representations comprehensible to the LLM through a projection layer.
- **LLM Understanding and Reasoning Stage.** Harnessing an existing open-sourced LLM as the core to process input information for semantic understanding and reasoning. The LLM not only directly generates text tokens but also produces unique “modality signal” tokens that serve as instructions to dictate the decoding layers whether & what modal content to output correspondingly.
- **Multimodal Generation Stage.** Receiving the multimodal signals with specific instructions from LLM (if any), the Transformer-based output projection layers map the signal token representations into the ones that are understandable to following multimodal decoders.

For more technical details, kindly refer to the [paper](https://arxiv.org/pdf/2309.05519.pdf).

conda activate nextgpt

# CUDA 11.6
conda install pytorch==1.13.1 torchvision==0.14.1 torchaudio==0.13.1 pytorch-cuda=11.6 -c pytorch -c nvidia

```

### 3. Training/Adapting NExt-GPT on Your Own

####

#### 3.1. Preparing Pre-trained Checkpoint [Back to Top]
NExT-GPT is trained based on following excellent existing models.
Please follow the instructions to prepare the checkpoints.

- `ImageBind`
is the unified image/video/audio encoder. The pre-trained checkpoint can be downloaded from [here](https://dl.fbaipublicfiles.com/imagebind/imagebind_huge.pth) with version `huge`. Afterward, put the `imagebind_huge.pth` file at [[./ckpt/pretrained_ckpt/imagebind_ckpt/huge]](ckpt/pretrained_ckpt/imagebind_ckpt/).
- `Vicuna`:
first prepare the LLaMA by following the instructions [[here]](ckpt/pretrained_ckpt/prepare_vicuna.md). Then put the pre-trained model at [[./ckpt/pretrained_ckpt/vicuna_ckpt/]](ckpt/pretrained_ckpt/vicuna_ckpt/).
- `Image Diffusion`
is used to generate images. NExT-GPT uses [Stable Diffusion](https://huggingface.co/runwayml/stable-diffusion-v1-5) with version `
v1-5`. (_will be automatically downloaded_)
- `Audio Diffusion`
for producing audio content. NExT-GPT employs [AudioLDM](https://github.com/haoheliu/AudioLDM) with version `l-full`. (_will be automatically downloaded_)
- `Video Diffusion`
for the video generation. We employ [ZeroScope](https://huggingface.co/cerspense/zeroscope_v2_576w) with version `v2_576w`. (_will be automatically downloaded_)

#### 3.2. Preparing Dataset [Back to Top]
Please download the following datasets used for model training:

A) T-X pairs data
- `CC3M` of ***text-image*** pairs, please follow this instruction [[here]](./data/T-X_pair_data/cc3m/prepare.md). Then put the data at [[./data/T-X_pair_data/cc3m]](./data/T-X_pair_data/cc3m).
- `WebVid` of ***text-video*** pairs, see the [[instruction]](./data/T-X_pair_data/webvid/prepare.md). The file should be saved at [[./data/T-X_pair_data/webvid]](./data/T-X_pair_data/webvid).
- `AudioCap` of ***text-audio*** pairs, see the [[instruction]](./data/T-X_pair_data/audiocap/prepare.md). Save the data in [[./data/T-X_pair_data/audiocap]](./data/T-X_pair_data/audiocap).

B) Instruction data
- T+X-T
- `LLaVA` of the ***visual instruction data***, download it from [here](https://github.com/haotian-liu/LLaVA/blob/main/docs/Data.md), and then put it at [[./data/IT_data/T+X-T_data/llava]](./data/IT_data/T+X-T_data/llava/).
- `Alpaca` of the ***textual instruction data***, download it from [here](https://github.com/tatsu-lab/stanford_alpaca), and then put it at [[./data/IT_data/T+X-T_data/alpaca/]](data/IT_data/T+X-T_data/alpaca/).
- `VideoChat`, download the ***video instruction data*** [here](https://github.com/OpenGVLab/InternVideo/tree/main/Data/instruction_data), and then put it at [[./data/IT_data/T+X-T_data/videochat/]](data/IT_data/T+X-T_data/videochat/).

Side note：After downloading dataset, please run `preprocess_dataset.py` to preprocess the dataset into a unified format.
- T-X+T (T2M)
- The `T-X+T` instruction datasets (T2M) are saved at [[./data/IT_data/T-T+X_data]](./data/IT_data/T-T+X_data).

- MosIT
- Download the file from [here](), put them in [[./data/IT_data/MosIT_data/]](./data/IT_data/MosIT_data/). (_We are in the process of finalizing the data and handling the copyright issue. Will release later._)

#### 3.3. Precomputing Embeddings [Back to Top]
In decoding-side alignment training, we minimize the distance between the representation of signal tokens and captions.
To save costs of time and memory, we precompute the text embeddings for image, audio and video captions using the text encoder within the respective diffusion models.

Please run this command before the following training of NExT-GPT, where the produced `embedding` file will be saved at [[./data/embed]](./data/embed).
```angular2html
cd ./code/
python process_embeddings.py ../data/T-X_pair_data/cc3m/cc3m.json image ../data/embed/ runwayml/stable-diffusion-v1-5
```

Note of arguments:
- args[1]: path of caption file;
- args[2]: modality, which can be `image`, `video`, and `audio`;
- args[3]: saving path of embedding file;
- args[4]: corresponding pre-trained diffusion model name.

#### 3.4. Training NExT-GPT [Back to Top]

First of all, please refer to the base configuration file [[./code/config/base.yaml]](./code/config/base.yaml) for the basic system setting of overall modules.

Then, the training of NExT-GPT starts with this script:
```angular2html
cd ./code
bash scripts/train.sh
```
Specifying the command:
```angular2html
deepspeed --include localhost:0 --master_addr 127.0.0.1 --master_port 28459 train.py \
--model nextgpt \
--stage 1\
--save_path ../ckpt/delta_ckpt/nextgpt/7b_tiva_v0/\
--log_path ../ckpt/delta_ckpt/nextgpt/7b_tiva_v0/log/
```
where the key arguments are:
- `--include`: `localhost:0` indicating the GPT cuda number `0` of deepspeed.
- `--stage`: training stage.
- `--save_path`: the directory which saves the trained delta weights. This directory will be automatically created.
- `--log_path`: the directory which saves the log file.

The whole NExT-GPT training involves 3 steps:

- **Step-1**: Encoding-side LLM-centric Multimodal Alignment. This stage trains the ***input projection layer*** while freezing the ImageBind, LLM, output projection layer.

Just run the above `train.sh` script by setting: `--stage 1`

Also refer to the running config file [[./code/config/stage_1.yaml]](./code/config/stage_1.yaml) and deepspeed config file [[./code/dsconfig/stage_1.yaml]](./code/dsconfig/stage_1.yaml) for more step-wise configurations.

Note that the dataset used for training in this step is included `dataset_name_list` and the dataset name must precisely match the definition in [[./code/dataset/catalog.py]](./code/dataset/catalog.py)

- **Step-2**: Decoding-side Instruction-following Alignment. This stage trains the ***output projection layers*** while freezing the ImageBind, LLM, input projection layers.

Just run the above `train.sh` script by setting: `--stage 2`

Also refer to the running config file [[./code/config/stage_2.yaml]](./code/config/stage_2.yaml) and deepspeed config file [[./code/dsconfig/stage_2.yaml]](./code/dsconfig/stage_2.yaml) for more step-wise configurations.

- **Step-3**: Instruction Tuning. This stage instruction-tune 1) the ***LLM*** via LoRA, 2) ***input projection layer*** and 3) ***output projection layer*** on the instruction dataset.

Just run the above `train.sh` script by setting: `--stage 3`

Also refer to the running config file [[./code/config/stage_3.yaml]](./code/config/stage_3.yaml) and deepspeed config file [[./code/dsconfig/stage_3.yaml]](./code/dsconfig/stage_3.yaml) for more step-wise configurations.

## 4. Running NExT-GPT System [Back to Top]

#### 4.1. Preparing Checkpoints

First, loading the pre-trained NExT-GPT system.
- **Step-1**: load `Frozen parameters`. Please refer to 3.1 Preparing Pre-trained Checkpoint.

- **Step-2**: load `Tunable parameters`. Please put the NExT-GPT system at [[./ckpt/delta_ckpt/nextgpt/7b_tiva_v0]](./ckpt/delta_ckpt/nextgpt/7b_tiva_v0). You may either 1) use the params trained yourselves, or 2) download our checkpoints from [Huggingface](https://huggingface.co/ChocoWu/nextgpt_7b_tiva_v0).

#### 4.2. Deploying Gradio Demo
Upon completion of the checkpoint loading, you can run the demo locally via:
```angular2html
cd ./code
bash scripts/app.sh
```
Specifying the key arguments as:
- `--nextgpt_ckpt_path`: the path of pre-trained NExT-GPT params.
