# Emolysis: A Multimodal Open-Source Group Emotion Analysis and Visualization Toolkit

This repo is official repository for the paper [Emolysis: A Multimodal Open-Source Group Emotion Analysis and Visualization Toolkit](https://arxiv.org/abs/2305.05255).

## Get Started

We provided a static demo review for you to try. Please visit [https://emolysis.controlnet.space/local/1](https://emolysis.controlnet.space/local/1).

If you want to analyze your own video, please follow the instructions below to deploy the server.

## Deploy the Server

### From Docker (x86 with CUDA)

Requires:
- Docker
- nvidia-docker

Run the server.
```bash
docker run --runtime nvidia -p <PORT>:8000 [-v <CACHE_DIR_FOR_MODELS>:/app/checkpoints] --name emolysis controlnet/emolysis
```

Then, you can access the app at `http://127.0.0.1:<PORT>`.

### From Source

Requires:
- Conda
- Node.js

Install dependencies.
```bash
npm install
npm run build
cd service
bash -i build_env.sh  # use `build_env.mac.sh` for arm-based mac
conda activate emolysis
cd ..
```

Run the server.
```bash
python service/main.py --port <PORT>
```

Then, you can access the app at `http://127.0.0.1:<PORT>`.
