# Seamless Streaming demo
## Running on HF spaces
You can simply duplicate the space to run it.

## Running locally
### Install backend seamless_server dependencies

Please note: we *strongly* recommend running the model on GPU. 

If running for the first time, create conda environment and install the desired torch version. The example below is for PyTorch 2.1.1 and variant cu118. Check [here](https://pytorch.org/get-started/locally/) to find the command for your variant. Then install the rest of the requirements:
```
cd seamless_server
conda create --name smlss_server python=3.8
conda activate smlss_server
conda install pytorch torchvision torchaudio pytorch-cuda=11.8 -c pytorch -c nvidia
pip install -r requirements.txt
conda install -c conda-forge libsndfile==1.0.31
```

### Install frontend streaming-react-app dependencies
```
conda install -c conda-forge nodejs
cd streaming-react-app
npm install
npm run build  # this will create the dist/ folder
```


### Running the server

The server can be run locally with uvicorn below.
Run the server in dev mode:

```
cd seamless_server
uvicorn app_pubsub:app --reload --host localhost
```

Run the server in prod mode:

```
cd seamless_server
uvicorn app_pubsub:app --host 0.0.0.0
```

To enable additional logging from uvicorn pass `--log-level debug` or `--log-level trace`.


### Debuging

If you enable "Server Debug Flag" when starting streaming from the client, this enables extensive debug logging and it saves audio files in /debug folder.
